Series of mining pneumatic submersible pumps
Series of mining pneumatic submersible pumps are a new product developed by ourselves. Series of mining pneumatic submersible pumps adopt mechanical products in which the rotor and the pump body are coaxially connected. They adopt vertical Structure, lower pump type.
The series of mining pneumatic submersible pumps are suitable for drainage operations in places containing gas and coal dust explosion hazards. They can be widely used on any working surface underground in coal mines to transport groundwater containing coal powder and sediment particles. They are safe and reliable to use. and effectively improve on-site air quality.
Technical features of the series of mining pneumatic submersible pumps
The series of mining pneumatic submersible pumps for coal mines have a compact structure and are easy to move, assemble, disassemble and maintain. The vortex of the pump body adopts a high-efficiency and energy-saving hydraulic model, and the impeller is specially designed. This water pump has the advantages of strong sewage discharge capacity, large flow rate and high lift.
The structure and working principle of the series of mining pneumatic submersible pumps
The series of mining pneumatic submersible pumps mainly consist of three parts: pump body, air motor and overflow.
The pump body is divided into The upper and lower chambers are separated from air and water by a sealing ring in the middle. The sealing ring adopts spring sealing, and uses the pressure of air and water to cause high-pressure air and water to enter the inner walls of the upper and lower sealing rings respectively, causing them to expand inward and enhance the sealing effect.
The air motor part consists of a rotor, turbine, bearings, etc. Using compressed air as power, the impact turbine drives the rotor to rotate at high speed to perform work.
The overflow part consists of water wheel, pump cover, suction port, pump base, etc. The water wheel is installed on the rotor shaft in the lower cavity of the shell. Compressed air is sent in from the air inlet. The rotor rotates to drive the water wheel. Under the action of centrifugal force, the water in the water wheel is pressed into the water outlet vortex of the shell and discharged along the water outlet pipe. .
Technical Parameters of Series Mining Pneumatic Submersible Pumps

4. Use, Maintenance and Maintenance
New pumps must be tested on the ground once before use. When running dry on the ground, the air pressure should be controlled within . The pump test time should not exceed three minutes to avoid high-speed operation, which will accelerate the wear of parts and reduce the service life.
. The inner diameter of the air inlet pipe must not be less than millimeters, and the working air pressure must not be lower than . Dry and clean to prevent impurities from entering, causing parts to wear or blocking the rotor and preventing it from running.
. The water wheel nut must be added with a spring washer to prevent the rotor from turning loose when the water returns, causing the impeller to sink and cause friction with the pump cover.
During the assembly and disassembly process of replacing wearing parts such as impellers, turbines and shooting rings, do not use heavy hammers to avoid damaging the matching accuracy of internal parts. Generally, after about fifteen days of continuous use, the air pump should be opened and cleaned once for maintenance.
The sewage air 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 granular media. premature damage due to inhalation.
The exhaust pipe should be exposed to the water surface, and water and other impurities cannot be allowed to enter the exhaust pipe to avoid corrosion of the internal parts of the turbine or jamming of the impeller and rotor.
5. Safety precautions
When there is no water, the air source should be turned off immediately and the machine should be shut down
The working air pressure should not be greater than.
If a fault is found, the machine should be shut down and used after repairs are normal.
6. Transportation and Storage
The product can be transported by conventional means. During transportation, reliable positioning and waterproofing measures should be taken to prevent vibration and impact. Rough handling and unloading are strictly prohibited, and transportation with corrosive substances is not allowed. The product should be stored in an upright position in a ventilated and dry warehouse, and must not be stored in the same warehouse as corrosive substances
7. Safety warnings for mining pneumatic submersible pumps
Be sure to install and use this product before Read the product instruction manual thoroughly and install and operate it strictly in accordance with the provisions of this instruction manual.
When installing the air intake pipe, impurities in the pipe and joints must be blown away to ensure clean and dry air to prevent impurities from entering the cylinder, causing wear of parts or blocking the rotor from rotating.
The exhaust pipe should be exposed to the water surface, and water and other impurities cannot be allowed to enter the exhaust pipe to prevent internal parts of the turbine from rusting or blocking the blades and rotor.
. The air pump rotates at a high speed (cooled by water), and the no-load operation time without water should not exceed minutes! To avoid damage to the machine parts and malfunction.
. When there is no water, the air source should be turned off immediately and the machine should be stopped
. The air pressure should not be too high.
If a fault is found, the machine should be shut down and used after repairs are normal.
Users cannot freely replace the standard accessories and main components.
