　　Mining explosion-proof submersible pumpMain purpose and scope of application

　　A、 Construction drainage of coal mine shafts and inclined shafts.

　　B、 Drainage at the bottom of the mine without a water storage tank.

　　C、 Drainage of mining face.

　　D、Pneumatic turbine submersible pump for coal minesClean up the sediment in the water tank and drain it.

　　E、 Suitable for underground drainage in coal mines with methane coal dust gas.

　　Mining explosion-proof submersible pumpThe wide application and characteristics of

　　Pneumatic turbine submersible pump for coal minesIt is a new type of drainage equipment that uses a pneumatic motor as a coaxial prime mover, which is not affected by power supply, humidity, dust and other conditions. Especially in places that require explosion-proof, it has the safety and reliability that electric submersible pumps cannot replace. It can be used in mining work faces containing various dangerous gases such as coal dust, as well as in harsh working conditions such as danger, vibration, and high temperature. It can ensure reliability and has the characteristics of novelty, advanced technology, energy saving, efficiency, low noise, lightweight, and low maintenance. It can be widely used in coal mines and any working face to transport underground water containing coal powder and sediment particles. It is safe and reliable to use, and can optimize on-site air quality.

　　useMining explosion-proof submersible pumpThere are some things to pay attention to when doing so

　　1. Before using the pneumatic submersible pump, it is necessary to conduct a ground load test run. When the wind speed is 0.6mpa, the pump should work for about ten minutes to check if it is running normally.

　　2. Connect a rubber hose with an inner diameter of 50mm to the drainage pipe to prevent gangue powder from entering the pump.

　　3Mining explosion-proof submersible pumpIt is strictly prohibited to operate without load. Due to the use of friction wheels to limit the speed of the pump, idling can cause an increase in frictional heating temperature and damage to parts, leading to accidents.

　　4. When assembling the turbine cover after maintenance, attention should be paid to aligning the nozzle outlet with the reverse chamber arc of the pump body

　　5Pneumatic turbine submersible pump for coal minesRegularly apply paint and pay attention to maintenance when not in use

　　6. When the operation is normal and there is no water supply, it is necessary to dismantle, inspect, repair or replace parts, and not to beat and beat again

　　Mining explosion-proof submersible pumpDismantling and Assembly

　　1. Dismantling procedure:

　　a、 Remove the protective cover and separate the lower pump cover from the volute.

　　b、Mining explosion-proof submersible pumpRemove the impeller nut of the water pump, and at the same time, remove the volute. Lightly tap the periphery of the volute to drive the water wheel and shaft apart.

　　c、 Remove the exhaust hood and separate the bearing seat from the housing at the same time.

　　d、 Remove the cover.

　　e、Pneumatic turbine submersible pump for coal minesUse the two M10 screw holes in the middle of the fan blade to separate the wind turbine from the shaft with two M10 bolts.

　　f、 Remove the shaft and take out the friction plate.

　　2. Assembly Procedure for FQW15-30/W Mining Pneumatic Submersible Pump:

　　a、 Simply proceed in the reverse order of disassembly.

　　b、Mining explosion-proof submersible pumpWhen installing the skeleton oil seal, special tools should be used to guide it to avoid damaging the oil seal.

　　c、 Before assembling the pump cover, move the water pump impeller by hand and observe whether there is any friction between the workpieces. If there is any abnormality, reassemble and debug.
