Wire saws are mainly divided into electric wire saws and hydraulic wire saws according to power

Advantages and disadvantages of electric wire saw

1. The saw head is relatively heavy. In actual construction, you can fix the saw head by directly pressing the bottom corner without using expansion screws, which greatly reduces the damage to the concrete cutting.

2. There is no need for a lot of cooling water. Anyone who has used hydraulic wire saws knows that hydraulic pumping stations must use cooling water to cool the oil temperature to reduce the problem. Electric wire saw machines do not need a lot of cooling water, only the rope head Just add cooling water, it can work for a long time.

3. Low cost: It can be operated by household electricity, eliminating the need for hydraulic system, so the cost is much lower.

Disadvantages: Inferior to hydraulic wire saws, it is flexible in construction, especially in places where the construction area is narrow. 2. The power is not as strong as the hydraulic power, and the efficiency is slower than that of the YG hydraulic wire saw.

The Basic Classification of Water Well Drilling Rigs

The essence of drilling is to try to solve the problems of breaking rock and removing cuttings, protecting well wall and deepening drilling. The water well drilling rig must complete water well drilling, well casing, well flushing and other operations. Through long-term production practice and scientific research, the drilling method can be divided into two drilling methods with industrial practical value: impact method and rotation method. Various well drilling rig models have evolved from these two methods.

According to drilling methods, water well drilling rigs are divided into three categories: impact drilling rigs, rotary drilling rigs and compound drilling rigs. According to the circulation method, it can be divided into four categories: mud positive circulation drilling rigs, mud reverse circulation drilling rigs, conventional air drilling rigs and air reverse circulation drilling rigs. According to the classification of drilling depth, it can be divided into three types: shallow well drilling rig, medium-deep well-drilling rig and deep well drilling rig. According to the type of assembly, it can be divided into three types: vehicle-mounted water well drilling rig, trailer mounted water well drilling rig and bulk water well drilling rig.

Understanding the common types and characteristics of water well drilling rig is only the first step to give full play to the use-value of the equipment. In order to make better use of the equipment and improve the drilling quality and operation efficiency of water wells, it is also necessary to do a good job in the design, selection, matching and use of drilling rigs. YG machinery will continue to organize and share relevant wonderful information for you.

Working principle of drilling pump

If the entire drilling construction process is compared to human life activities, then the drilling pump, like the human heart, is the source of continuous circulation of drilling fluid from the ground to the bottom of the well, and then back to the ground from the bottom of the well. The drilling pump sucks the drilling fluid in the circulating tank, and at a pressure of 10-30 MPa and a delivery displacement of 20-60 liters per second, it passes through the ground high-pressure manifold, hose, drill pipe, and drill nozzle to the bottom of the well. , It will also form a high-pressure jet when flowing through the nozzle of the drill bit. Play the role of breaking rocks, cleaning the bottom of the well, and cooling the drill bit. When drilling with bottom hole screws or turbodrills, drilling fluid is the power source for power drilling tools. If the drilling pump fails to work normally and the drilling fluid cannot maintain circulation during the drilling process, downhole drilling engineering accidents will occur. It's as if the human heart stopped beating. Click here to know more details.

Drilling pump classification

A reciprocating pump is a kind of drilling pump commonly used in oil drilling rigs, and its function principle is exactly the same as that of general reciprocating pumps. The power end of the drilling pump is a set of crank and slider mechanisms. Because the liquid transported is mostly mud, it is also called a mud pump. There are many types of drilling pumps, which can be divided into double-cylinder pumps and triple-cylinder pumps according to the number of hydraulic cylinders of the pump. According to the number of times the piston sucks or discharges liquid once, it can be divided into single-acting pumps and double-acting pumps. At present, the most widely used oil drilling rigs at home and abroad are double-cylinder double-acting and triple-cylinder single-acting piston drilling pumps.

Work efficiency

The efficiency of the drilling pump directly affects the speed and progress of drilling. The pump valve, piston, cylinder liner and seal of the YG mud pump are the weakest parts of the drilling pump because they have been working in the drilling fluid containing fine sand for a long time, and the working environment and conditions are harsh. In recent years, with the joint efforts of scientific research and manufacturing units, my country has developed a number of high-quality, long-life drilling pump accessories, which greatly improves the working efficiency of drilling pumps.

Mud pump development

In the 1980s, due to the rise and development of jet drilling technology, the matching update speed of high-horsepower drilling pumps was greatly accelerated. In just over ten years, the mud pump has developed from 600 horsepower in the past to 800, 1000 and 1300 horsepower now. Individual deep well drilling teams are also equipped with 1,600-horsepower drilling pumps.

Sandblasting Machine & Air Compressor

An automatic sandblasting machine is a machine that uses compressed air as the power to form a high-speed jet beam and spray the material at high speed to the surface of the workpiece to be processed. So that the mechanical properties of the outer surface of the workpiece surface are changed. Air compressor is the basic product of modern industrialization. It is a device that converts the mechanical energy of the prime mover (in general, electric motor) into air pressure energy.

How to Choose Air Compressor?

The use of a sandblasting machine is inseparable from the air compressor. The air generated by the air compressor acts as a motive force in the sandblasting process. Different sandblasting machines need different air compressors. Sandblasting machines can be divided into general pressure wet sandblasting machines, pressure sandblasting machines, and high pressure sandblasting machines in terms of the efficiency and strength of sandblasting. The air compressor connected with the sandblasting machine generally selects a pressure of 0.8Mpa. Then select the appropriate air compressor according to the size of the air source required by the sandblasting machine.

What types of sandblasting machines?

The normal pressure sandblasting machine is the siphon sandblasting machine. Compared with the other two types of sandblasting machines, the efficiency of sandblasting is lower than that of pressurized and high-pressure sandblasting machines. The air compressor required for each gun on this type of sandblasting machine has an air output of at least 1 cubic meter per minute, that is, an air compressor of at least 7.5KW. If you want to learn more about wet blasting machines for sale, please view them here.

Both pressurized sandblasting machines and high-pressure sandblasting machines belong to pressure-feeding sandblasting machines. The blasting efficiency of a single gun is lower than that of the high-pressure type. The air compressor required for each gun on the pressurized sandblasting machine has an air output of at least 2 cubic meters per minute, which is a 15KW air compressor.

The air compressor required for each gun on the high-pressure sandblasting machine has an air output of at least 3 cubic meters per minute, which is a 22KW air compressor. Click here to know more about grit blasting machine manufacturers.

Optional machine

In general, the bigger the air compressor, the better. If you consider the cost, you can refer to the above data for selection. The air compressor and the sandblasting machine need to be equipped with an air storage tank and a dryer. The gas storage tank is used to store the gas generated by the air compressor to ensure the stability of the air source. The dryer is used to dry the oil and moisture in the air to ensure that the air is dry when it reaches the sandblasting machine. It also reduces sand blocking problems caused by sand agglomeration.

Introduction of drilling rig machine

Drilling rigs are mechanical equipment for drilling holes on the surface. Drilling rigs include outdoor drilling equipment for large water wells, oil wells and natural gas wells. It also includes small devices that can be moved by a single person, called augers.

Drilling rigs can sample underground mineral deposits or be used to install underground production equipment. Such as underground machinery, instruments, pipelines and hoistways. Drilling rigs can be mobile equipment installed on trucks, trailers, or tracks.

Drilling rigs can also be relatively fixedly installed on land and offshore structures (such as drilling platforms, which are generally referred to as "offshore oil rigs", although they do not include drilling rigs). The term "drilling rig" generally refers to equipment that drills into the earth's crust.

The rig includes

Small portable drilling rig. Such as mining drilling, water wells drilling machine price, environmental survey drilling rigs.

Large-scale drilling rigs can drill the earth's crust to a depth of more than thousands of meters. During the drilling process, the mud pump circulates the mud through the drill pipe and the drill bit into the casing annulus to cool the drill bit and remove cuttings.

The lifting system on the drilling rig can lift hundreds of tons of drill rods. Other equipment can pump acid or sand into the reservoir, perform fracturing operations, and guide crude oil or natural gas out of the reservoir to the surface. In remote areas, drilling rigs can be equipped with permanent residential facilities, eating tools, etc., which can be provided for the daily lives of more than one hundred employees. Offshore drilling rigs can operate at a distance of several hundred kilometers offshore, and personnel on the well will rotate.

Drilling rigs are classified according to drilling type

Because different YG drilling rig types allow drill rods to enter the borehole in different ways, each has advantages and disadvantages. According to the depth that can be drilled, sampling type, cost, and insertion rate, there are two basic drilling types. : Cuttings drilling and core drilling.

Down the hole drilling uses a spiral drill to rotate into the ground, and the soil is lifted to the ground through the gap of the spiral blade. Hollow drill pipes can be used for drilling, geological drilling, soil engineering and geochemical exploration of mineral deposits in soft soils such as swamps and other soils where the soil does not open naturally. Solid flying drills/short tube augers are used for hard soil drilling. Sometimes, mining shafts are drilled with auger rods. Small drill machine rods can be installed on trucks, and large augers can be used to place bridge foundations.

Spiral drill pipes are generally used for relatively soft unconsolidated materials or rocks in bad weather and are characterized by economy and speed.

Disposable latex glove production line Production process

To produce disposable latex gloves, the main raw materials and additives are first stirred and mixed in a special container in a certain proportion to form an emulsion. After filtering, vacuuming, and standing still, the mixture is pumped into the dipping tank in the production line. Under normal production conditions, the hand molds on the assembly line automatically enter the dipping tank, and the hand molds that adhere to the emulsion come out of the dipping tank in turn, and continuously rotate during the journey to make the emulsion on the surface of the hand mold uniform and make the excess emulsion hang down. Drip down. The dripping liquid returns to the immersion tank through the collection tank.

After dripping the excess emulsion, the hand mold moves into the oven with the production line. The temperature of the oven is controlled at 230-250 degrees Celsius. Under this condition, the emulsion that is touched by hand is cured and formed. The hand mold coming out of the oven undergoes processes such as natural cooling, lip curling, and powder dipping. The gloves are manually removed from the hand mold, and the hand mold continuously moves to the dipping tank. The unloaded disposable latex gloves will be put into storage as a finished product after powder removal. Check here to know more details.

Oxygen production equipment is equipment for producing gaseous oxygen. Oxygen production equipment includes three aspects: industrial oxygen production equipment, household oxygen production equipment, and medical use oxygen generator.

Industrial oxygen production equipment

The principle of industrial PSA oxygen production equipment is to use air separation technology. First, the air is compressed at a high density and then the difference in the condensation point of each component in the air is used to separate the gas and liquid at a certain temperature, and then it is obtained by further rectification. Industrial oxygen is generally obtained through this physical method. The oxygen generator is also called air separation equipment. According to the number of products, it can be divided into small-scale oxygen generator equipment below 800m3/h; medium-sized equipment from 1000-6000m3/h; large-scale equipment above 10000m3/h. The so-called 800m3/h and 1000-6000m3/h represent the hourly output of the oxygen plant from the air separation tower. China's oxygen production equipment is generally composed of air compressors, pre-cooling devices, purification devices, and air separation towers.

Household oxygen production equipment

The working principle of household oxygen-making equipment: using molecular sieve physical adsorption and desorption technology. The oxygen-making machine is filled with molecular sieves, which can absorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and becomes after purification. High purity oxygen. The molecular sieve discharges the adsorbed nitrogen back into the ambient air when it is decompressed and can absorb nitrogen and produce oxygen during the next pressurization. The whole process is a periodic dynamic cycle process, and the molecular sieve is not consumed.

Medical oxygen production equipment

All medical oxygen production equipment adopts the world's advanced PSA (pressure swing adsorption) air separation oxygen production technology, which is based on the difference in the adsorption capacity of the attractant (zeolite molecular sieve) on oxygen and nitrogen in the air to achieve oxygen and nitrogen Separate. When air enters the bed filled with adsorbent, nitrogen has a strong adsorption capacity and is adsorbed, but oxygen is not adsorbed so that a high concentration of oxygen can be obtained at the outlet end of the adsorption bed. Because the adsorbent has the characteristic that its adsorption capacity changes with pressure, changing its pressure can make adsorption alternately perform adsorption and desorption operations.

Regardless of the purpose of the oxygen production equipment, the physical oxygen production method is adopted, and the oxygen is separated by isolating the air.
