How To Operate Mortar Spraying Machine?

The mortar spraying machine is easy to operate, no need to take scaffolding, no mobile equipment, no need to repair the raft, the yin and yang horns, the top plate can be freely sprayed, shortening the construction period, improving the progress, and saving the cost of the frame material, but in the operation process We still have a lot of details to pay attention to.

Mortar Spraying Machine Operation Guide

1. Before each shift, first press the hand oil pump several times to fill the transmission part.

2. After turning on the power, first electric motor, check whether the rubber spiral rotation direction is consistent. If it is inconsistent, replace the power phase line (this check should be done every time the power is reconnected).

3. Connect the conveying hose and nozzle, add 5L of clean water to the hopper, start the motor to clear the water pump, and wet the hopper, pump body and conveying hose, and stop the pump after most of the water is pumped out.

4. Put the putty or paint into the hopper to start spraying (should start the air compressor and open the damper).

5. It is strictly forbidden to idling in the state of no material and no water in the hopper.

6. After the work is finished, drain the remaining material in the hopper, and fill enough water in the hopper, clean the hopper, and pump it out, clean the hose and the nozzle until the pump is full of water, so as to avoid the residual material in the hose. Solidify, block the hose and nozzle.

7. If the downtime is too long, wipe the mortar spraying machine clean and remove the booster screw. After oiling, keep it in a safe place and reinstall it when using it.

8. In the mortar spraying machine work process, there is insufficient pumping pressure, and the booster stator bolt or the pressurized rubber sleeve and the booster worm can be adjusted.

9. Before mortar spraying machine working, the sprayed area should be infiltrated with water; when spraying, the nozzle should be vertically and sprayed as far as possible (the distance can be adjusted according to the spraying effect), and it can be sprayed evenly and coordinated with the leveling process. If the wall is too dry or sprayed for too long, it will seriously affect the leveling effect and change the process.

10. The material in the hopper should be evenly distributed and should not be interrupted. When the conveying screw rotates, it is strictly forbidden to stir with the stick in the hopper to prevent injury.

11. Once the spray pipe is blocked, switch the switch to the manual position, only open the compressor, remove the quick joint before the pump head, and then block the nozzle downward, the wind pressure will generate reverse pressure, and the pipe will be remnant. Blow out, put the quick connector on, and start normal work.

12, when the spray hand operation, should wear helmets, protective glasses, protective clothing and other protective equipment.

13. The pressurized rubber sleeve and the booster screw are wearing parts. In order to prolong the service life, the booster stator bolt is in a loose state when it is used for the first time. When the pressure is reduced and the flow rate is significantly reduced, the compression bolt is adjusted to make it In normal working condition.

Spraying Machine Parts Component

The spraying machine is mainly composed of a feeding device, a spray gun and an atomization generating source. The atomization source varies with different types and sprayers: the atomization source of the air sprayer consists of an air compressor, a gas pipe, an air oil water separator, and a gas storage tank; the air spray machine atomization source is powered by a power source. The composition of the high-pressure pump; the atomization generating source of the electrostatic spraying machine is composed of a high-frequency high-voltage electrostatic generator.


It consists of two parts: shotcreting and drying. The working mechanism includes a spray booth equipped with a spray head, a leather conveyor belt, a drying system and a cleaning mechanism. After 2012, the rotary multi-nozzle sealed spray chamber was used. The nozzle was opened and closed by ultrasonic or computer control, which realized the leather spray, no leather and no spray; saving the paint agent, reducing pollution and high coating efficiency. The sprayed leather is fed to the drying zone by a conveyor belt and collected from the other end after drying.

The spraying machine is a special spraying equipment using high pressure airless spraying technology.

High-pressure airless spraying, also known as airless spraying, uses a high-pressure piston pump to directly pressurize the paint to form a high-pressure paint that is sprayed out of the muzzle to form an atomizing airflow on the surface of the object (wall or wood surface). Compared with air-spraying, the paint surface is uniform and has no graininess. Because it is isolated from the air, the paint is dry and clean. Airless spray can be used for the construction of high viscosity paints with clear edges and even for some spray projects with boundary requirements. Depending on the type of machine, it is also divided into a pneumatic airless sprayer, an electric airless sprayer, and an internal combustion airless sprayer.

Principle And Application Of The Rebar Detector Introduction

In the concrete structure inspection, it is necessary to detect the position, diameter and thickness of the steel bars in the concrete. The site is usually tested by the rebar detector. This paper mainly introduces the working principle and usage of the rebar detector.

First, the rebar detector working principle

(1) According to the electromagnetic field theory, the coil is a strict magnetic dipole. When the signal source supplies alternating current, it is radiated to the outside.

The electromagnetic field is emitted; the reinforcing bar is an electric dipole that receives an external electric field, thereby generating an induced current that is distributed along the reinforcing bar. The induced current of the steel bar re-radiates the electromagnetic field (ie, the secondary field) to the outside, causing the original excitation coil to generate an induced electromotive force, thereby causing a change in the output voltage of the coil. The reinforcing bar position measuring instrument determines the reinforcing bar according to the change. The location and thickness of its protective layer. Moreover, when the reinforcing bar is directly above, the output voltage of the coil is most affected by the secondary magnetic field generated by the reinforcing bar. Therefore, in the test, during the movement of the probe, the most affected point, that is, the point with the largest signal value, can be automatically locked. The thickness value is obtained according to the correspondence between the thickness of the protective layer and the signal.

(2) The rebar detector consists of a host, a probe and a signal line, wherein the probe has a transmitting and receiving function; the host has processing data and a display function. The electromagnetic signal is emitted by the probe of the rebar detector, and the steel bar in the concrete member generates a secondary induced magnetic field, which is received by the receiver in the probe, and shows the thickness of the protective layer of the steel bar, the diameter of the steel bar and the spacing of the steel bars after data processing by the host.

Second, the use of introduction

1. Precautions

(1) It is not possible to test concrete containing ferromagnetic substances;

(2) Select the appropriate test surface, the test surface should be clean and flat, and the metal embedded parts should be avoided;

(3) For the structure and components with the facing layer, the finishing layer should be removed and then tested on the concrete surface;

2. Operation steps

(1) Preheating and zeroing the instrument before performing the test;

(2) When the test is performed, the probe moves on the detection surface until the thickness of the protective layer displayed by the instrument is the smallest.

The center line of the head coincides with the axis of the steel bar, mark it at the corresponding position, and follow the above steps to position the adjacent other steel bars.

(3) Set the range of the instrument and the nominal diameter of the steel, and select the adjacent steel bars along the measured steel bar axis to have less influence.

Position, and avoid the steel joint and the wire, read the concrete detection value of the first test, repeat the test at the same position of the measured steel bar, read the thickness of the concrete cover layer detected in the second time, such as the same When the read output differs by more than 1mm, it should be re-tested;

(4) After positioning the steel bar, record the nominal diameter of the steel bar displayed on the positioning mark every steel.

Repeat the test twice, the probe should be rotated 180° in the second test, and each reading must be consistent;

How Far Should Acrow Prop Be?

How far should acrow prop be? This depends on the length of the work surface.

First of all, we need to understand the difference between "hydraulic support" and "single hydraulic prop"

1. The hydraulic support is an important part of the fully mechanized mining equipment. It can reliably and effectively support and control the roof of the working face, isolate the goaf, prevent the meteorite from entering the mining face and propelling the conveyor. It is used together with the shearer to realize comprehensive mechanization of coal mining, to solve the contradiction that the roof management in the mechanized coal mining work lags behind the coal mining work, further improve and improve the efficiency of coal mining and transportation equipment, and reduce the labor intensity of coal miners. Limit the safety of coal miners.

The hydraulic support is used on the fully mechanized mining face. The general width is 1.5m. According to the length of the face, it can be calculated how many hydraulic supports are needed. Of course, the selection of hydraulic supports has strict requirements and will not be described in detail here.

2. The single hydraulic acrow props use the liquid pressure to generate working resistance and realize the single retractable pillars for lifting and unloading. They are used on the working surface during general mining or blasting. Of course, the advanced support of the fully mechanized mining face is partially used in advance. Most of the brackets are supported by a single hydraulic acrow prop.

The spacing of the single hydraulic acrow props is divided into the column spacing and the row spacing. According to the length of the surface, it is possible to calculate how many monomers are needed, generally 60-100 cm.

In addition, the longest working face in China is currently more than 300m, and more than 200 of the fully mechanized support can be used on one side.

What kind of hydraulic acrow prop do you need? Tell me the length of your work surface, we will calculate exactly how many acrow props you need for you!!!

How Is The Scraper Winch Operation

Although the majority of users use the scraper winch, although they know how to operate, but the specific operation steps and routine maintenance of the scraper winch may not know very clearly, I will explain in detail the "Scraper Winch Operation".

Step / Method

1

Check before work or open an empty test drive, pay attention to the lubrication condition is good, do not use dirty, non-standard lubricants when adding lubricant. And always pay attention to whether the temperature rise is normal, when the scraper winch has a faulty problem, it is not allowed to continue to work. The leader should be informed and the maintenance master should be assisted to eliminate the fault.

2

When the motor is started, the transmission gear starts to run. At this time, the brake band on the reel is clamped, and the shank on the large gear should be loosened, so that the reel does not rotate, and only the large internal gear rotates.

3

To start the reel, the brake band on the roll must be completely loosened and the brake band on the large internal gear must be tightened. At this time, the reel is rotated and wound up to work.

4

During the working process of the scraper winch, if the scraper winch is temporarily stopped, the brake band of the upper wheel should be loosened and the brake band on the reel should be tightened.

5

When the position of the towed load is scheduled by the micro-range, it is only necessary to alternately lift or press the left and right brake levers to stop the revolving between the reels. When operating the brake lever, attention should be paid to the protection of the shoulder pin, the joint bolt and the pad.

6

If the parking time is long, you should hold the brakes and turn off the motor.

7

The opening and stopping of the reel must be rapid to reduce the wear of the brake band, but it is not allowed to drive and stop in a hurry to prevent damage to the transmission.

8

When there is often a counter-torque effect on the scraper winch reel, both brakes must be in good contact and secure.

9

When the motor is running, the two brakes cannot be braked at the same time to prevent the motor from being burnt.

Always pay attention to the working condition of the brakes. If the brakes are not working, they must be adjusted. The grease and dirt that falls on them must be cleaned.

The temperature of the drum brake belt and bearing of the scraper winch shall not exceed 70 °C. If the temperature rises drastically, it must be stopped for inspection.

The seal must be intact to prevent dust ingress and oil spillage.

Check whether the rope head is secure, whether there is damage or biting inside the transmission mechanism, and whether the internal parts are excessively worn. Only after checking and confirming that it is correct can you drive.

The temperature of the motor should not exceed the specifications of the machine.

The scraper winch must not exceed the rated load for work.

Each team must carefully maintain the various parts of the scraper winch every day, remove dirt when leaving work, and there should be no dust on the motor.

Employees in charge of maintenance must check the use of the scraper winch frequently, assist in the handling of temporary failures, conduct regular inspections of the scraper winch, prevent malfunctions and accidents, and make maintenance records.

If the scraper winch is left unused for a long time, appropriate measures should be taken to protect it from rust or damage.

For the specific repair of the scraper winch, please refer to the eight methods of common fault handling of the scraper winch.

Precautions

1.When the motor is running, the two brakes cannot be braked at the same time to prevent the motor from being burnt.

2.The temperature of the drum brake belt and bearing of the scraper winch shall not exceed 70 °C. If the temperature rises drastically, it must be stopped for inspection.

3.The scraper winch must not exceed the rated load for work.

4.Check before starting work or drive an empty car.

How To Maintain Cement Plaster Spraying Machine

Before any maintenance operations, the pressure must be removed and the balloon valve closed.

1. According to the viscosity of the paint and the thickness of the particles, select the appropriate filter filter screen. After used cement plaster spraying machine, the dirt on the filter should be removed in time, and the damaged filter should be replaced in time.

2. When diluting the paint or cleaning equipment, the solvent specified by the paint should be used to prevent the paint from abnormally depositing or agglomerating, blocking the passage of the paint filter, high pressure valve port, high pressure pipeline and spray gun, and it is impossible to spray. In particular, when diluting the coating, it must be strictly in accordance with the technical requirements of the coating to avoid affecting the performance of the coating.

3. The two major components of the cylinder and gas distribution system should not be scrubbed with strong organic solvents, and should not be immersed in strong solvents. All rubber seals in the equipment can only be cleaned with gasoline or non-solvent cleaners.

4. Cylinders, gas distribution systems, upper and lower pilot valves, oil misters, pressure regulators and other pneumatic components. Do not enter rust, sand, dust, etc. during assembly after cleaning and maintenance. The foreign matter on the air intake filter should be cleaned regularly to prevent the intake air from decreasing and affecting the cement plaster spraying machine pressure.

5. After used cement plaster spraying machine, the spraying machine should be cleaned in time. Otherwise, curing the agglomerated coating will aggravate the wear of the paint cylinder, piston rod, seal ring and other parts, and shorten the service life of the cement plaster spraying machine.

6. If you need to replace all the important parts such as seals (rubber or Teflon), paint cylinder, piston rod, paint hydraulic system pressure parts, spring, air motor and gas distribution system during maintenance, please choose genuine Original accessory products to ensure the normal operation of the cement plaster spraying machine.

8. Material ratio (cement) 0.7:3 mortar.

Here in the purpose of the majority of consumers responsible, we still have a few things to remind you: buy the manufacturer's website pictures, video is professional, from the site content to determine the professional level of the factory, must pay attention to the factory to confirm the situation . If there is no website, the situation of the manufacturer can be imagined;

Whether the manufacturer has a business license, whether there is a formal contract, whether to open a formal invoice, etc., each industry has a lot of leather bags companies, all from the other invoices, if the manufacturers are general taxpayers, the credibility is relatively high;

If the situation allows for the first purchase, try to visit the manufacturer to check the quality and professionalism of the products and accessories; if the conditions such as the schedule are not allowed, you can find the real shot or video display of some equipment through the network. For the next product, make another judgment.

Dot column or other temporary support.

The acrow props is suitable for the inclined coal seam mining face with the coal seam inclination angle less than 25 degrees - 35 degrees. The condition of the coal seam top and bottom plate is: the roof is not affected by the recovery of the pillar, the bottom plate should not be too soft, and the pillar is not pressed into the bottom plate. Deteriorate the integrity of the base plate, otherwise the base should be enlarged. When used in a soft coal mining face, protective measures should be taken on the surface of the live cylinder to prevent collapse. When the pillar is used with the wooden top beam or used as a point column, the top cover should be replaced with a column cap to avoid damage to the wooden beam.

Acrow props classification:

According to the liquid supply mode and the working fluid, it is divided into external liquid supply type (referred to as external injection type) and internal liquid supply type (referred to as internal injection type).

According to different working strokes, it is divided into single telescopic (single stroke) pillars and double telescopic (double stroke) pillars. When the stroke characteristics are not specified, it is a single telescopic pillar.

According to different materials used, it is divided into ordinary steel pillars, high titanium alloy pillars, aluminum alloy pillars, stainless steel pillars, etc., and steel pillars are not indicated when the material characteristics are not indicated.

According to the structure, it can be divided into two types: piston type pillar and plunger suspension type pillar. The piston type pillars are further divided into single telescopic and double telescopic pillars according to the working stroke. The plunger suspension column uses an aqueous medium and is an “environmentally friendly” pillar. At present, there is a new series of SZK single hydraulic props in foreign countries. The three-purpose valve is arranged on the outside of the cylinder block, and the liquid supply pipe is welded outside the cylinder to connect the three-purpose valve with the cylinder internal cavity.

The inner diameter of the single-pillar cylinder is φ63mm, φ70mm, φ80mm, φ90mm, φ100mm, φ110mm, φ125mm, among which the φ100mm cylinder diameter pillar is the most used in the well, and the φ63mm, φ70mm, φ125mm cylinder diameter pillars are mainly used for special purposes.

The maximum height of the single pillars is 0.63m, 0.8m, 1.0m, 1.2m, 1.4m, 1.6m, 1.8m, 2.0m, 2.24m, 2.5m, 2.8m, 3.15m, 3.5m.

In recent years, three specifications of 3.8m, 4.0m and 4.5m have been added. In principle, the pillars of 3.5 meters or more are not used as working surface support, but can be used for end and advanced support.
