Introduction Of Steel Mine Supports

The steel mine support is a passive support for coal mine support. Steel mine support has high tensile strength and compressive strength. Steel mine support also has good toughness performance, high support force, high support strength, and can be used multiple times. Steel mine support is widely used in mine roadways, especially in deep complex roadways and soft coal roadways.

Steel mine supports are mainly used for secondary support of mine tunnels and mine tunnels through mountain tunnels. The optimal stress state of the steel mine support is that the main material of the steel mine support-U-shaped steel is evenly compressed after the wall is filled and compacted. When the surrounding rock pressure value used on the steel mine support reaches a certain value, the support will produce The compression reduces the pressure of the surrounding rock on the steel mine support, so as to avoid the pressure of the surrounding rock being greater than the bearing capacity of the steel mine support and damaging the support.

According to the specific conditions on site, flexibly choose the type, structure and shed spacing of the steel mine support, correctly guide the construction of the steel mine support of the tunnel, ensure its effective and reliable work, and speed up the tunneling speed, reduce the amount of roadway later repairs, and ensure It is of great significance to produce safely, extend service life, obtain better technical and economic benefits, and give full play to the support performance of steel mine supports.

Rotary Water Well Drilling Rig Machine

Rotary water well drilling rig machine, it mainly relies on the rotary motion of the drilling tool to break the rock formation into holes. There are five main types:

(1) pot cone. The pan cone drill is used to rotate and cut the soil layer. According to the size of the drill, they are respectively called cauldron cone and small cauldron cone, which can be driven by manpower or power. The cuttings fall into the pot and are lifted to the ground. Its simple structure, low efficiency, suitable for the general soil or sand pebble soil layer. The drilling depth is 80 ~ 100 meters for small pot cone and 30 ~ 40 meters for large pot cone.

(2) circulating mud wash rotary drilling machine. By tower, hoist, rotary, drilling tools, mud pump, faucet and motor. During the operation, the power machine drives the rotary table through the transmission device, and the drill bit is driven by the active drill pipe to rotate and break the rock. There are positive and negative cycles. During the operation of the positive circulation drill, cuttings at the bottom of the well are carried out of the wellhead through a circular channel outside the drill pipe. After settling in the sedimentation tank, mud flows back to the mud pool for recycling. During the operation of the reverse-circulation drill, mud will flow from the wellhead to the bottom of the well after settling in the sedimentation tank. Mud carrying cuttings will be pumped upward from the well by sand and gravel pump through the bit nozzle and through the inner cavity of the drill pipe and back to the sedimentation tank. The drilling machine has a high rising velocity in the drill pipe, strong ability to discharge cuttings and pebbles, fast drilling speed, suitable for soil, sand and loose formation with pebble diameter smaller than the drill pipe inner diameter. The drilling depth is generally less than 150 meters.

Drilling Rig Industry

A drilling rig is a machine that creates holes in the earth subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers. Drilling rigs can sample subsurface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called 'offshore oil rigs' even if they don't contain a drilling rig). The term "rig" therefore generally refers to the complex equipment that is used to penetrate the surface of the Earth's crust.

Small to medium-sized drilling rigs are mobile, such as those used in mineral exploration drilling, blast-hole, water wells and environmental investigations. Larger rigs are capable of drilling through thousands of metres of the Earth's crust, using large "mud pumps" to circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the "cuttings" while a well is drilled. Hoists in the rig can lift hundreds of tons of pipe. Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas; and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred). Marine rigs may operate thousands of miles distant from the supply base with infrequent crew rotation or cycle.

Petroleum drilling industry

Oil and natural gas drilling rigs are used not only to identify geologic reservoirs but also to create holes that allow the extraction of oil or natural gas from those reservoirs. Primarily in onshore oil and gas fields once a well has been drilled, the drilling rig will be moved off of the well and a service rig (a smaller rig) that is purpose-built for completions will be moved on to the well to get the well on line.[8] This frees up the drilling rig to drill another hole and streamlines the operation as well as allowing for specialization of certain services, i.e. completions vs. drilling.

Mining drilling industry

Mining drilling rigs are used for two main purposes, exploration drilling which aims to identify the location and quality of a mineral, and production drilling, used in the production-cycle for mining. Drilling rigs used for rock blasting for surface mines vary in size dependent on the size of the hole desired, and is typically classified into smaller pre-split and larger production holes. Underground mining (hard rock) uses a variety of drill rigs dependent on the desired purpose, such as production, bolting, cabling, and tunnelling.

Features: Small size, high power, high efficiency, accurate positioning. And can use the magnetic force of the suction, drilling from different angles. Used in conjunction with coring bits, the effect is better; at the same time, the problem of removing slag in the pipeline is also solved, and the overlapped drilling of steel plates can also achieve satisfactory results, and the problem of stainless steel pipes and stainless steel drilling with a certain thickness can be solved.

The magnetic drill is a mobile high-efficiency tool that uses the electromagnetic principle to pass the magnetic seat to attract the rig frame and the rotary drilling mechanism to the surface of the steel workpiece for drilling. The magnetic drill has two main parts.

The first part: The magnetic base, such as the black rectangular parallelepiped part below, its effect is that after the power is turned on, the magnetic drill generates a magnetic attraction force of thousands of kilograms perpendicular to the bottom of the magnetic base through the electromagnetic effect, so that it is firmly absorbed on the steel plate or the structural surface It plays the role of a fixed machine. The stronger the magnetic attraction force, the more stable the body of the magnetic drill when it is working, and the higher the drilling accuracy.

Part II: Drilling, which is divided into two parts:

1. It is a fixed part. It is fixed when drilling. The main function is to control the motor, such as switching the gear position.

How To Make The Concrete Mixer Pump Wearing Parts "Longevity"

Operators of concrete mixing plant pumps should have such experience: in the work, some parts of concrete pumps are damaged prematurely, which increases the cost of equipment maintenance for users, and also seriously affects the efficiency of construction operations. So, it is worth discussing how to improve the service life of vulnerable parts of concrete pump. The small edition is introduced from the following four aspects:

Cutting ring and spectacle plate are a pair of closely matched parts with relative motion. The contact surfaces of both parts are welded with a layer of wear-resistant material. The clearance between them can be adjusted in (0.1-0.2) mm by means of special-shaped nuts at the end of S-shaped tube spline shaft. The rubber spring assembled between the S-shaped tube and the cutting ring enables the cutting ring and the spectacle plate to move relatively flexibly and freely. With the prolongation of service time, the rubber spring loses its elasticity, and the joint surface of the cutting ring and the eyeglasses plate will be worn, resulting in the gap between the two enlarged. When the gap is more than 0.7mm, it should be adjusted immediately, otherwise the pumped mortar will enter by "gap". Once the mortar enters the friction surface, the wear rate of the cutting ring and the spectacle plate will be greatly accelerated.

When pumping concrete, the cutting ring oscillates with the swing of S-shaped pipe and plays the role of cutting concrete. Therefore, the wear rate of the cutting ring is faster. The higher the concrete pressure at the outlet, the worse the wear degree of the cutting ring. Usually, the wear of the cutting ring first occurs at the edge, and it is located in two symmetrical parts with 90 degrees above. Therefore, when the above parts of the cutting ring are worn out, the cutting ring can be rotated at an angle in time to continue to use, which is equivalent to doubling the service life of the cutting ring.

Screw Air Compressor

The Importance Of Good Sealing Performance Of Mortar Pump

The sealing gasket used in the mortar pump and the pipes through which the air source is supplied shall be made of non-toxic, odorless, non-particle falling off and corrosion-resistant materials. Internal pressure metal support frame is embedded in the pump shell, which limits the permanent deformation of the plastic pump shell under axial expansion under heat and axial compressibility under compression, overcomes the shortcomings of the plastic pump body, such as easy to produce compression deformation, cold shrinkage deformation and other mechanical performance instability, and effectively improves the operating stability of the plastic anti-corrosion and anti-wear pump.

In the key parts that are easy to wear out, the high wear-resistant material suitable for inlay solves the problem of short service life and high operation cost of slurry transfer pump in the high temperature leaching section of wet smelting. Can transport all kinds of corrosive and abrasive slurry and liquid, especially hfm-i two-stage booster pump, especially suitable for mortar pump pressure feeding, so that the mortar pump high efficiency, good filtering effect, filter cake less water content, pump sealing, long service life, low maintenance cost. The mortar pump is composed of motor, cycloidal needle wheel reducer, reciprocating gear and hydraulic working end. Flow ≤ 60m3/h, head ≤ 1.2mpa, suction ≤ 10m, temperature ≤ 80 ℃.

The mortar pump can withstand various corrosive media (acid, alkali, salt) and organic solvents within a certain range of temperature and concentration, and impregnate in 80 kinds of organic solvents at 20℃ and 90℃ for 30d. There was nothing abnormal in appearance, and little change in other physical properties.

Food Cooking Stainless Steel Or Aluminum Deep-fried Pan

A deep-fried pan refers to a kitchen appliance that uses a cooking oil as a main raw material to perform a frying cooking process on a food. It has the characteristics of novel style, reasonable structure, simple operation, fast heating speed and easy cleaning. It is a kitchen equipment widely used in fast food restaurants, hotels and dining places.

Fryers are divided into: electric heating, coal heating, gas heating and other heating methods. It is a smokeless, multi-functional, oil-water hybrid frying equipment. This equipment adopts the most internationally selected oil-water mixing frying process, which completely changes the structure of traditional frying equipment and fundamentally solves the traditional style. The disadvantages of the frying pan can be fried at the same time, and the food is not scented. It is multi-purpose. The process adopts the method of heating from the middle of the oil layer to control the temperature of the upper and lower oil layers, effectively alleviating the oxidation degree of the oil, and inhibiting the acid medium. High, automatic filtration and residual temperature during the frying process, automatic temperature control, thus extending the service life of the fried oil.

1. Using the principle of skill, the oil does not change. The principle of different proportions of oil, water and animal oil is used. The residue generated in the working process is completely submerged in water, and the animal fat sinks into the lower layer of vegetable oil, which fundamentally solves the residue in the traditional fryer. Animal fats and oils, repeated frying, causing the oil to be acidified and carbonized to cause carcinogens.

2, improve the quality, ensure the health of the special process to make the residue and animal oils leave the working layer, plus the middle heating to effectively control the convection of the upper and lower oil layers, thus ensuring the purity of various oil layers, the fried food is not only color and flavor, the appearance is clean and beautiful (no dark spots Phenomenon), improved product quality and extended shelf life.

3, saving oil, good for environmental protection This product solves the problem of excessive evaporation of oil caused by the overheating of traditional fryers. The oil-water mixing technology allows the water below the oil layer to continuously generate a small amount of steam, and penetrates into the oil layer to replenish the frying oil, thereby inhibiting the oil from being volatilized. The central heating process can control the upper and lower temperatures according to the needs of the electronic control device. The degree of oxidation of the frying oil inhibits the production of acid, which prolongs the life cycle of the frying oil and reduces waste. It saves more than 50% of oil compared with the traditional fryer, while reducing air pollution, allowing the operator to avoid the smoke. The bitterness.

4, the oil does not taste, the machine uses the process to control through the limit, partition temperature control, scientific use of the specific relationship between vegetable oil and animal oil, so that the animal oil leached from the fried food naturally sinks into the lower layer of vegetable oil, so that the middle and upper working oil is always maintained Pure, can also fry a variety of food at the same time, do not taste each other, a multi-purpose machine, can increase your business varieties.

5. This machine is equipped with advanced automatic temperature control device. The oil temperature can be adjusted arbitrarily between normal temperature and 230 degrees. After selecting the temperature according to the explosive, the heating can be automatically controlled to ensure the constant temperature, which not only reduces the energy consumption.

Hand-Operated Popsicle Making Popsicles Is Convenient And Safe

As the weather gets hotter, popsicles and ice creams are starting to hit the market. I remember when I was a child, I often saw a car with a popsicle on the street, covered with a large quilt. I didn’t know why I had to put a quilt. Now I want to isolate the outside temperature and prevent the popsicle from melting.

Inevitably, most people have eaten a long popsicle in Southeast Asian countries such as Thailand, Myanmar, Laos, etc. These popsicles are all enclosed in drums filled with ice cubes. This is the hand-cranked popsicle that is popular in Southeast Asian countries. machine. So, how does a hand-operated popsicle make a popsicle?

According to the relevant personnel, first of all, the crushed ice is directly put into the popsicle machine. What is unexpected is that after adding half of the water, you need to put about 5 kg of salt. The purpose is to make the popsicles not freeze into ice at low temperatures, affecting the soft taste.

Next, put a layer of insulation into the jack and insert the cleaned and sterilized cup on the jack. Put the prepared solution into each cup after putting it, such as cola, black tea, green tea, yogurt, fresh milk, etc. It is worth noting that don't add too much and fill it up two or three times. After closing the lid, manually rock the popsicle machine back and forth.Once again, after shaking the popsicle machine for a few minutes, open the lid, insert the bamboo stick into the cup that has not been frozen, and then cover it with the lid to continue shaking. After about 10 minutes, the liquid in the cup will completely condense into a popsicle. Simple, convenient and fast.

Finally, when selling popsicles, you only need to take the cup out of the popsicle machine, put it into the clear water and soak it a little. Move the bamboo stick to the left and right, and the popsicle can be taken out for consumption.

Automatic Ramen Noodle Maker Machine

The automatic ramen machine is a mechanical device for making noodles, and the steps of making noodles are divided into: dough, face, face, face, face and face.The process of making handmade kneading is very complicated and painstaking. It is very time-consuming and physically demanding for face, face, face, face, face and ramen. The automatic ramen is invented for this need. Like other automation equipment, it replaces labor with machines.

The automatic ramen machine refers to the case of hand-made noodles, and the amount of water used in the dough is relatively large, about 45% of the flour. When the flour is mixed with water, mash, andthe starch and protein in the flour will absorb the water to the utmost extent. When the starch absorbs water, it will become sticky, and when the protein absorbs water, it will become gluten. The combination of the two is the dough for the dough. The longer the dough is hand-baked, the better it is to form a gluten network and increase the stickiness, which provides the most basic conditions for the good taste of the hand-picked noodles.

When the dough is well formed, the automatic ramen machine is also used to simulate the continually changing the angle of the palm of the hand, so that the force of the dough is evenly distributed, and there is no uneven force. Produce a "dead angle." When you lick the dough, you usually put the dough stick on the dough and push it forward. When you turn it to the ellipse, you don’t have to lick the front and back, but also lick the left and right sides to make the whole skin thick and consistent. Rolled on both sides into a roll, or folded into a trapezoid, cut into noodles with a knife.
