Sanitary Garbage Truck Daily Maintenance And Cleaning Method

If you interested to know more detail information about the sanitation garbage truck?

Please click here !!!

At present, the country pays more and more attention to environmental protection throughout the country, and various rectification efforts are becoming more and more important. Some units must have corresponding treatment measures and sanitation garbage trucks. The previous open-air discharge and manual landfill treatment are no longer allowed. As the punishment increases, companies invest more and more in environmental protection projects. The national environmental protection project is moving towards an era where people's lives are healthier and sanitation work is more intelligent. There are more and more sanitation garbage trucks on the road, and the city is building better. Various sprinklers, sanitation garbage trucks, and road sweepers frequently shuttle through the city. In the streets and lanes, they are like beauticians in the city's blood vessels, purifying the city's blood and making the beautiful city glow with new brilliance.

Sanitation garbage trucks play an increasingly important role in urban environmental protection, and the workload is getting heavier and heavier. Among them, sanitation garbage trucks are doing the dirtiest and most tiring work, and they are hard-working and hardworking. Many sanitation garbage trucks we see on the roads. It is dirty. Due to the heavy workload every day, it is rarely paid attention to maintenance and cleaning. However, after the sanitation garbage truck has been working for a long time, the dust and garbage accumulated on the surface and inside of the vehicle body will cause wear of the line and pipeline components. Increase, often cleaning the vehicle and repairing key parts can avoid many parts damage accidents and increase the service life. If the vehicle is not maintained for a short period of time, it will not work for two or three years. It is not a problem to use it for 5-7 years. It is usually in the car. Spend a little time on your body and you can save money on buying a new car. Don't act quickly!


The first step of sanitation garbage truck cleaning: the body surface. Most of the body is dust, dirt and oil. You can use water pipes or water guns to wash the sediment on the surface of the car from top to bottom. Do not use washing powder and other detergents. Because washing powder and detergent contain high content, long-term use will be To make the sanitation garbage truck paint tarnish, make it matte or even chapped, use car wash liquid or shampoo instead of using a rag to wipe the dirty oil. Then rinse the rear of the car body and then clean the lower part of the car body. In this step, the chassis should be thoroughly rinsed to thoroughly clean the edges, bends, fenders and other parts. In particular, sand and dirt on wheel and brake disc parts, wing parts and front mesh parts, door frames and skirts should be thoroughly cleaned.

The second step: the cab. Long-term use in the cab by smoke, sand, driver's perspiration or air circulation system, causing air pollution in the cab, and then bacteria breeding, and even produce unpleasant strange smell, making the seat cushion moldy, leather aging. It affects both physical and mental health and affects driving mood. Therefore, professional care should be taken according to the situation, and dust and cleaning should be done in time. Some instrument lines should be inspected frequently, and the aging lines should be replaced in time, and deal with them in case of failure.

The third step: Inside the sanitation garbage truck box. The sanitation garbage truck belongs to a sealed box, which is difficult to clean thoroughly, and should pay attention to key parts at a high price. In the connection between some boxes and internal moving parts, it should be checked frequently. If foreign matter is caught, it should be cleaned in time to avoid further wear. If there is too much garbage on the push plate and cylinder, clean it in time to avoid affecting work efficiency.

The influence of wall Rendering machine on the construction industry

Although it is now a big technology era, but when it comes to the construction industry, our first impression should be that real estate is very hot, and our people have a fascination with the house! And because of the huge demand for housing. Therefore, the workers are continually urged to work as soon as possible.

For such a large amount of work, the construction workers are overwhelmed and they are struggling every day. However, even if they work day and night, they still can't keep up. Under all kinds of difficulties, the savior of the construction industry was born, that is, China Transport Group automatic intelligent wall rendering machine.

The automatic intelligent wall rendering machine is a new star machine in the construction industry. Since its birth in 2002, it has developed a new product after continuous research and development experiments by China Transport Group.

How To Increase The Waste Detector Success Rate Of Finding Water?

1, PQWT series water detector to start the first test, why should I delete the retest?
The China Coal series of geophysical probes is the latest intelligent frequency selection technology developed in China. Generally, when the first point is first tested, the frequency parameters will be automatically adjusted according to the site environment. There may be instability. It is recommended to save and save again after measurement.


2. How to make the same section repeat measurement image response consistent?
The same section repeats the measurement direction, the MN line spacing, the dot pitch, and as close as possible, so that the repeated measurement images are consistent. If the image display is abnormally large, check for abnormal changes caused by interference factors such as wires, transformers, and large mechanical operations. If there is no interference or a large abnormality, you can choose to use the PQWT series of water detector to solve this problem.

3. How to arrange the dot pitch and the pole pitch? What effect does the dot pitch and pole distance have on the measurement results?
The point size is generally determined according to the size of the measured target. The larger the target is, the larger the distance is, and the smaller the target is, the smaller the distance is. For small anomalies such as dyke leakage and fissure water, you can choose a distance of 1 m or less. For example, if you are measuring the groundwater with a pebble layer or a large amount of water, you can choose a larger distance measurement (5-10 m) to avoid water finding. Prospecting of water and minerals.
The smaller the pole distance (length of MN line), the weaker the received signal, and the greater the interference, especially the electric field strength of the measurement area is small (the overall value of the measurement data is below 0.1). The length of the MN line can be appropriately increased to obtain more stability. Data, generally choose 10-20 meters is better


4. Why do some blue areas in the profile show water, and some blue areas do not produce water?
We all understand that the blue region of the profile represents the relative minimum or maximum resistivity of the entire profile, rather than representing water. Even in the non-aqueous formation, even the blue region (resistivity relative minimum or maximum) represents only the formation. Resistivity, not water, is often a greater chance of water in an aquifer. Of course, attention should also be paid to the water-bearing conditions such as the aquifer, the fracture layer, the cave or the fault, the fissure, etc. in the formation. If the local structure itself is easy to enrich water, the blue area on the structural belt is often easy to effluent.

5. Does the aquifer on the map only look at the blue area?
Not necessarily, rocks with large water permeability and large gaps, as well as pebbles, coarse sand, loose sediments, cracked rocks, and karst-developed rocks can all be aquifers. Water is low-resistance, and the rock density and resistivity in the aquifer can be unknown high or low. The geological conditions in different regions are different, which will cause different color reactions in the aquifer. The blue to yellow layer may be aquifer. Color, can only say that the water-rich rock formation area generally looks at the blue area. Therefore, it is best to collect local hydrogeological information before using the China Coal Water detector. If possible, do more experiments in the local known water wells to find out the characteristics of the local aquifer. It is better to use the water detector to guide the well.

6. What is the impact of the small number of measuring points causing the line to be too short?
The Chinese coal water detector can automatically map at least 6 points. If the distance is too small (assuming 1 meter), the line will be too short, reflecting less geological information. It is difficult to comprehensively analyze the underground geological conditions, which is easy to cause. Wrong judgment. The longer the line is, the more the reaction information is. The probability of increasing the success is generally recommended to be 10-20 points or more.

7. Can I measure after the rain (ground wet)?
Whether it is a natural electric field instrument or an artificial electric field instrument, when the ground is wet, the ground will form a low-resistance shield, which will affect the measurement depth, but the same profile humidity has little effect on the natural electric field instruments, but for the artificial electric field. Class instruments have a large impact.

8. What is the difference between an electromagnetic probe (no need for a wire) and an electrode measurement?
The position of the measuring point of the electromagnetic probe is directly below the probe; the position of the measuring point of the electrode rod is the center point of the MN electrode rod, the electromagnetic probe is obtained by measuring the magnetic field and converted into an electric field signal, and the electrode rod is directly obtained by measuring the electric field signal to obtain the resistivity. . In some areas, there is a diametrically opposite abnormal reaction.

9. What functions must the phone be turned on during measurement?
The Bluetooth function needs to be turned on, and the mobile phone traffic is not consumed when measuring. The Chinese coal water detector is like this

10. How to deal with wires, high-voltage lines, network cables, underground pipes, metal objects, etc. when measuring? What is the interference with the measurement results?
It is best to stay away from high-voltage lines, wires and other power facilities on the ground, especially the high-voltage lines are better than a few hundred meters away. If you can't move away from the parallel wires and high-voltage lines as much as possible, and each line needs to be measured more than 2 times, look for the common anomaly area of ​​the two color maps. Improper measurement and disposal in high-voltage lines, electric wires, etc. will result in inaccurate measurement data due to excessive electric field strength in the vicinity, and the geological information displayed by the color map is distorted, misleading the user to make a wrong judgment.
For small underground metal pipes and metal objects, it has little effect on the measurement results; for relatively large metal objects, it will form a certain low-resistance shielding for the natural field; reduce the depth of detection of the instrument. If the metal pipe is charged, electromagnetic interference will occur, causing the measurement data to be inaccurate and should be kept away.

11. What is the gap between the known wells? It is clear that there is water measured to reflect the absence of water.
Due to the influence of artificial drilling, grouting, etc., the underground geological structure has undergone major changes. It is recommended that the known wells will produce a situation that does not correspond to the original geological information. well.

12. How to interpret the intensive, loose and closed lines of the measured graph?
Contours are dense and indicate that the resistivity of the nearby rock formation changes greatly. Looseness indicates that the resistivity of the rock formation changes little, and the surrounding rock resistivity values are equal.

13. What is the minimum and maximum area in the profile?
The minimum value represents the low value of the resistivity of the rock formation on the section, and the maximum value represents the abnormal value of the high resistivity of the rock formation on the section.

How to maintain the noise of the excavator?

If the noise occurs for a long time in the excavator work, it will not only affect the health of the construction personnel, but also indicate that the components of the excavator have corresponding faults. Today, China Transport professional editor mainly introduces the common noise faults of several hydraulic components of excavators.

Hydraulic pump noise
There are three main reasons for the noise of the hydraulic pump:
1) Hydraulic pump suction
When the air is mixed into the hydraulic oil, it is easy to form air pockets in the high pressure zone and propagate in the form of pressure, causing oil to oscillate, causing noise in the system. The main reasons are: the oil filter of the hydraulic pump, the oil inlet pipe is blocked or the hydraulic oil viscosity is too high, causing the vacuum of the hydraulic pump inlet port to be too high, so that the air penetrates; the hydraulic pump, the pilot pump shaft end oil seal is damaged or the oil inlet pipe Poor sealing, causing air to enter; oil tank oil level is too low, so that the hydraulic pump suction pipe is sucked.
When there is high noise in the working of the hydraulic pump, the above parts should be inspected first, and the problem should be dealt with in time.

2) Excessive wear of hydraulic pump components
If the cylinder of the plunger pump and the fitting plate, plunger and plunger hole are worn or strained, the hydraulic pump will leak seriously. When the hydraulic pump outputs high pressure and small flow hydraulic oil, flow pulsation will be generated. Higher noise. At this time, the inclination of the pilot system variable mechanism can be appropriately increased to improve the influence of the internal leakage on the output flow of the hydraulic pump.
The servo valve spool of the hydraulic pump and the piston that controls the flow will also cause the piston to pulsate during the movement due to local wear and strain, resulting in fluctuations in the output flow and pressure of the hydraulic pump, resulting in a large vibration at the outlet of the hydraulic pump. And noise. At this point, components that are severely worn or strained can be brushed, ground, or replaced.
3) Distribution plate failure
When the valve plate of the hydraulic pump is in use, due to surface wear or sludge deposition on the opening of the unloading groove, the unloading groove becomes shorter and the unloading position is changed, which causes a trapped oil phenomenon, which in turn causes high noise. During the normal repair process, the flat-repaired distribution plate will also shorten the unloading groove. If it is not slender in time, it will generate a lot of noise. In addition, it should be noted during the assembly process that the large unloading groove of the distribution plate must be assembled in the high pressure chamber, and its sharp angle must be opposite to the direction of rotation of the pump body, otherwise large noise will be generated.

Relief valve noise
The overflow valve is prone to high-frequency noise, which is mainly caused by the unstable performance of the pilot valve, which is the noise generated by the high-frequency oscillation of the front chamber pressure of the pilot valve.

The main reasons are:
Air is mixed into the oil to form a cavitation in the front cavity of the pilot valve to cause high frequency noise. At this time, the air should be exhausted in time and the outside air should be prevented from re-entering.
The needle valve is excessively worn due to frequent opening during use, so that the tapered surface of the needle valve and the valve seat cannot be tightly combined, resulting in unstable pilot flow and pressure fluctuations, which may cause timely repair or replacement.
The pilot valve is unstable due to the spring fatigue deformation, which causes the pressure fluctuation to be large and causes noise. At this time, the spring should be replaced.
Hydraulic cylinder noise
There are two main reasons for noise in hydraulic cylinders:
Air is mixed in the oil or the air in the hydraulic cylinder is not completely exhausted, causing cavitation under high pressure and causing large noise. At this time, the air must be exhausted in time.
The cylinder head oil seal is too tight or the piston rod is bent. During the movement, noise will also be generated due to “not strong”. In this case, the oil seal or alignment piston rod must be replaced in time.

Pipeline noise
Excessive dead bends or loose clips can generate vibration and noise. Therefore, the bending of the pipe should be avoided as much as possible, and the loose clips should be tightened in time.
In addition to troubleshooting the size of the excavator from the noise level, according to the color of the exhaust gas (smelling the woman, smelling the "fart" repairing machine, how to do it?), working conditions, etc. can also diagnose and repair the fault of the excavator, Learn more, stay tuned!

How To Maintenance The Road roller?

First, hydraulic system maintenance
Regularly change the hydraulic oil. When adding or changing oil, pay attention to clean and avoid the wind. Be careful not to mix impurities and dirt into the fuel tank. The filter element is replaced every 2,000 hours, even if it is not enough for two years, it needs to be replaced to prevent the hydraulic oil from deteriorating. Pay attention to the oil level gauge on the side of the fuel tank. When the hydraulic oil is too small, add the same type of hydraulic oil of the same brand to prevent the chemical reaction of the additives in various brands of hydraulic oil, leading to early grinding of hydraulic components. Also, always check the mounting bolts of the filter, valve, motor, oil pump, cylinder, etc. for looseness and oil leakage at each joint.


Second, the vibration wheel maintenance

The vibration wheel should be replaced once every 1000 hours (the lubricating oil is the same type of 15w/40 diesel engine oil as the engine), and should be cleaned when changing the oil. Check the vibration of the vibrating wheel oil at any time. When checking the oil level, turn the fuel filler to the upper position and open the oil drain to make the oil leak out until it leaks or leaks.



Third, battery maintenance

The Zhongyun Group's road roller adopts maintenance-free batteries, which are normal and require no maintenance. In the winter, the battery should be disassembled and stored indoors.

For equipment that uses rechargeable batteries, the electrode needs to be maintained for a long time, so that if the battery is improperly used or improperly maintained, the electro-hydraulic gravity will be low, the voltage during charging will be extremely high, and the voltage during discharge will be extremely low. White crystal particles were found outside the plate to form the "acid salt" of the battery, rendering it unusable. The acidified battery can be charged normally by charging 1-2 times with a small current. The surface of the battery must be kept clean. If there is dust or electrolyte flowing out, it is best to wipe it with a cloth dampened with ammonium chloride alcohol or 10% ammonium sulfate.

In terms of charging condition, it can be checked by acid hydrometer to see if the battery is fully charged. The specific gravity of the electrolyte should be 1.28 (15oC) when fully charged. If the specific gravity drops to 1.2, the battery should be borrowed from other sources. Charging. Under normal conditions, the diesel generator is sufficient to fully charge the battery, but in the winter, the battery pack is recommended to remain fully charged to avoid freezing.



Fourth, water spray system maintenance

During the winter storage period, the equipment should be stored indoors as much as possible. For the water spray system, you need to open the water pipe joint at the hinge, open the pipe joints at both ends of the spray pipe, clean the water of the system as much as possible, disassemble the water spout, the water tank, the water tank filter, the water pump, the water pipe, and the water spray pipe. Water. Avoid frostbite.

For small equipment, you can also add low temperature wiper to the system and follow the steps above. Avoid residual water damage to water system components.



Fifth, pay attention to lubrication points


For other equipment, the grease lubrication point should not be ignored. The lubrication points of the whole car are in any position. For each equipment, it should be recorded, especially in the high-strength construction, the lubrication time specified by the manufacturer, winter. Before storage, before the start of spring, it is necessary to record and record one by one according to the lubrication point record to extend the service life of the original.


Sixth, the whole machine is clean, stored and transported

In terms of cleaning, the road roller must be washed away from dirt and dust after each operation. At this time, special attention should be paid to diesel engines, generators, starter motors, fuel injection pumps, fuel injectors, hydraulic pumps, etc., as well as hydraulic piping. To clean the exterior, these areas must be wiped clean with a dry, soft cloth. Test all device functions and check all service points. If problems are found, solved in time, or ordered repair parts, repairs are completed before the start of construction in spring, to avoid delays in the second year of construction.

When the equipment does not need to be idle, the road roller should be stored in a dry warehouse. It is forbidden to store unrelated items and gasoline. In case of parking in the open air on rainy days, the parking ground should be kept dry. It must be covered with a rainproof cloth.

When the road roller needs to be transported for short distances, the roller can be driven by high speed according to the road conditions. Try to avoid long-distance transportation, causing damage to the surface of the steel wheel and high-temperature oil leakage and wear of the reducer. Long-distance transfer should be transported by flatbed trailer. During lifting and transportation, the safety locking device on the fuselage should be used to lock the frame to prevent relative rotation between the fuselage and the frame, causing damage to the swing limit block and fracture of the tubing. At the same time, the road roller should be firmly fixed on the flatbed trailer. For the steel wheel equipment, the crushing damage of the hard parts in the transport ladder and the transporting bucket should be avoided as much as possible. For the lashing point, the lining should be placed to prevent damage to the hoisting point.

"If you want to do something good, you must first sharpen your tools." Doing a good job of daily equipment maintenance will make you more effective in future construction.

Introduction of Pneumatic Pick Brazing 

Pneumatic pick brazing is a tool for the production of rock drilling equipment and equipment related accessories. It mainly produces various types of rock drilling equipment such as pneumatic hammer , pneumatic picks brazing, crushers, rock drills, anchor drills, bolt mounters, coal drills and related accessories. Rock hammer is divided into pneumatic hammer and hydraulic hammer according to different dynamic media (compressed air, hydraulic pressure), mainly used for breaking road surface, building removal or secondary rock crushing. Pneumatic pick brazing can be divided into conventional pneumatic brazing and high pneumatic brazing. The pneumatic pick brazing is a manual hand-held operation, and the hydraulic brazing is mechanically operated.




Pneumatic Pick Brazing Use Precautions

1.Do not use the pneumatic hammer as a lever;

2. Use within the specified working angle and scope;

3. It is strictly forbidden to exceed the maximum friction temperature value (350 degrees);

4. Try to avoid empty play; before the pneumatic hammer is used, it is necessary to lubricate the wind oil;

5. When using the pneumatic hammer, the spare air is not less than 3, and the continuous working time of each wind shall not exceed 2.5h.

6. Hold the broom handle and press it in the direction of the chisel when operating, so that the pick brazing is strong against the brazing sleeve;



7. The inner diameter of the selected trachea should be 16mm, and the length should not exceed 12m, and ensure that the tube is clean, clean and the joint of the trachea is firm and reliable;

8.When operating,do not insert all the pick brazing into the broken object to prevent air strikes; when the pick brazing is stuck into the titanium crucible, do not force vigorously shake the pneumatic hammer to avoid damage to the body;

9.When operating, reasonably select the pick brazing. According to the different hardness of the titanium crucible, to choose different pick brazing . The harder the titanium crucible is, the shorter the pick brazing is.Pay attention to the hotness of the brazing tail to prevent the pick brazing from being stuck;

10.When squeezing the burrs, it should be handled in time, and the burrs should not be used;

11, No air strikes
The pneumatic pick brazing is stuck in the rock. Do not shake the air violently to avoid damage to the threaded parts of the cylinder block and the connecting sleeve. Before Working you should check the mating of the tail and the pro-sleeve.In order to prevent the pick brazing from being bent and stuck,the gap should not be too big or too small,

Application Range Of Pneumatic Pick Brazing 

The pick brazing is directly in contact with the work object, the size and shape of the pick brazing is significantly affected by the productivity of the pneumatic hammer. The shape and length of the pick brazing are determined by the hardness of the ore layer, and the harder the ore layer is, the shorter the pick brazing will be. For soft or cracked ore layers, choose the 300-400 mm length pick brazing;for the hard and tough ore layer ,choose the 150-300 mm length pick brazing.
