Mine explosion-proof submersible sand discharge electric pump submersible sand discharge electric pump manufacturer direct sales to Inner Mongolia

Overview of mine explosion-proof submersible sand discharge pump>

Mining explosion-proof submersible sand discharge electric pump is used for local water accumulation in coal pits at the bottom of tunnels and tunnels in underground coal mines and drainage of coal preparation plants. It is an advanced and reliable drainage tool used in engineering drainage and other occasions.

Mining explosion-proof submersible sand discharge electric pumps are particularly suitable for use in coal mine tunnels, mining working surfaces and other places where the working environment contains explosive gas mixtures of methane or coal dust. It discharges groundwater and contains small amounts of suspended solids. Coal powder, rock chips, coal particles, sand, gravel, mud and other solid particles of sewage.

The unit can drain shallow water on the surface of the working surface, and can also work submerged in water for a long time. The electric pump has the advantages of compact structure, light weight, easy to move, no need for water diversion, double-sided sealing, durability, safety, reliability and strong adaptability.


>Structural features of mine explosion-proof submersible sand discharge electric pump

The upper part of the structure of mine explosion-proof submersible sand discharge electric pump is explosion-proof. The motor used in the submersible sand discharge pump has a mechanical seal in the middle and a water pump in the lower part. The motor, mechanical seal and water pump are coaxially connected.

The electric pump is composed of an impeller, a volute, a water inlet, a water outlet, and other parts. The impeller is fixed with a key and is fastened with a nut.

The motor used in the flameproof submersible sand discharge electric pump is a three-phase AC flameproof dry-type squirrel cage asynchronous motor. The stator winding uses polyester enameled wire, which greatly improves the life of the motor.

The cable adopts a special sealing structure to prevent water from entering the inside of the motor. The mechanical seal adopts an integral double-end mechanical seal. It is installed on the motor shaft of the sealing chamber. The sealing chamber is filled with mechanical oil, but it is not allowed to be filled. A certain space should be left to prevent the motor from heating up during operation and the expansion of the mechanical oil to damage the seal

< br/> >The working principle of the explosion-proof submersible sand discharge electric pump for mining

After the electric pump is turned on and started, the stator will generate a rotating magnetic field to rotate the rotor, thereby driving the impeller to rotate. Due to the centrifugal force of the blades The water is lifted through the volute through the water pipe to the desired height at a high flow rate and high pressure.
