Product features: :: :
Based on the original mining pneumatic submersible pump, the design parameters of the volumetric vane pneumatic motor are optimized. A supporting factory with advanced casting production
technology (coated sand gravity casting) is selected to process the aluminum alloy shell to improve the air tightness and tensile strength of the pneumatic motor shell
and improve the product performance. The development of silencers to reduce the noise of pneumatic motors has improved the underground industrial and mining environment.
Differences from other pumps of the same type: :: :
The design parameters have been optimized, the air inlet structure of the motor has been improved, the working chamber for the expansion and work of the pneumatic motor has been added, and the
shaft power. The mine air inlet quick connector is formed by the lost wax casting process, which is durable and convenient for users to use.
The aluminum alloy shell of the wind motor adopts advanced casting technology, and the air tightness and tensile strength of the shell are significantly improved.
The cloth-coated bakelite blades are molded with high temperature and high pressure of polymer materials, with uniform dimensional tolerances, and closely consistent molecular structures inside and outside
Good dimensional stability, small deformation, moderate hardness and flexibility, and wear resistance Durable, greatly improving service life.
The swirl impeller is a semi-open bidirectional inclined blade shape, which has strong sewage discharge capacity. The centrifugal pump impellers are all semi-open vortex composite blade shapes.
The impeller material is formed by the lost wax casting process, which is durable and has a high lift. The curve is flat.
The submersible pump is equipped with a muffler that utilizes the air flow energy of the exhaust noise of the wind motor. It has no power loss and no noise. When the water pump is running at full flow
it can further increase the pump lift and can be fully submerged underwater. work, greatly improving the practicality of the submersible pump.
The turbine air pump adopts a double air inlet form and re-adjusts the structural parameters of the moving impeller to achieve higher aerodynamic efficiency. The main structural parts are made of high-quality sheet materials, which reduces the weight of the whole machine and makes it easier to move.

Selection of mining pneumatic submersible pumps: :: :
The general selection should be based on the actual wind pressure underground, the actual water quality of the mine, the actual required flow rate, etc. Parameter selection, product quality can be selected according to the material of the blade. The blades made of high-temperature and high-pressure polymer materials have uniform dimensional tolerances, closely consistent molecular structures, good dimensional stability, basically zero deformation, and durability. It is durable and can greatly extend the service life of the air pump.
Generally, for drainage operations in coal mine well construction or tunnel projects, air pumps and/or are mostly used. These two types of air pumps have large flow rates and high lifts, and are basically applicable. The water wheel of the air pump is floating on the vortex of the pump body. Above the chamber, the throughput is larger than /
and is suitable for working conditions with a lot of mud and impurities in the water. The water wheel of / is sunk in the vortex chamber of the pump body. The water wheel has a large diameter and a high lift ratio. , but the mud concentration in the water should not be too large. Users should choose based on the actual situation
when selecting.
Use, care and maintenance: :: :
For volumetric vane air pumps (except oil-free self-lubricating wind motors), the oil mist of the air pump should be filled with machinery before use
Oil, during no-load test operation on the ground, the air pressure should be controlled and should not exceed 1 minute to avoid high-speed operation and accelerate parts wear, thus reducing the service life.
Before connecting the air inlet hose to the water pump air inlet joint, the dirt, sand, gravel and other debris in the air inlet pipe and the joint should be blown away to avoid entering the
cylinder and causing the cylinder to rupture or the rotor to be stuck and unable to operate. It is strictly prohibited to remove the stainless steel wire protective mesh
cover installed in the air inlet joint.
The inner diameter of the air inlet high-pressure hose is average (except for special requirements of the user). In order for the performance of the air pump to meet the design requirements, it should
ensure that its working air pressure is between ~.
During the use of the air pump with a lubricator, machine oil should be injected into the lubricator once per shift according to regulations.
It is not allowed to operate without lubricating oil, and it is not allowed to use grease instead. .
If any malfunction or abnormal sound is found during use, the air source should be shut down immediately for maintenance. During the disassembly and assembly process of replacing wearing parts, do not hit with a heavy hammer to avoid damaging the accuracy of internal parts. Generally, after one month of continuous use, the air pump should be opened and cleaned once for maintenance and upkeep. During installation, you should strictly follow the company's assembly and disassembly sequence regulations to extend its service life. If the blades are worn to the limit, they should be replaced in time. After the wind motor is assembled, it should be flexible when turning the shaft head by hand without any jamming. When installing the water pump impeller nut, a spring washer should be installed to prevent the rotor from turning loose when water returns, causing the impeller to loosen and sink and the pump body to rub,
affecting the normal use of the air pump.
The air pump rotates at a high speed. When there is no water, the air source must be turned off. Long-term no-load operation is prohibited to avoid damage to internal parts. The wind
pump can be used in turbid water containing a lot of rock powder and sediment. It can pass through particles and will not be blocked by the inhalation of small solid particles or fibers, nor will it be blocked by the inhalation of granular media. Premature damage due to inhalation.
The exhaust port of our company's air pump is connected to a muffler with independent intellectual property rights, but the exhaust interface should be exposed to the water to prevent sewage
Impurities directly enter the inside of the cylinder from the exhaust port, causing corrosion of parts or damaging the blades. The rotor is stuck, affecting normal use. Assembly steps of vane type mining pneumatic submersible pump: :: :
