Mining flameproof submersible sand pump Structural features:

1 BQS trapping by the mining flameproof submersible electric pump structure, the upper part of motor, the central for mechanical seal, lower for the pump. Motor and pump mechanical seal and coaxial connection.


2 Electric pump impeller, volute, inlet section, outlet and other parts, impeller fixed by the nut fastening


3 For the three-phase ac motor flameproof dry-type squirrel-cage asynchronous motor. Stator winding use polyester, make motor life is greatly improved.


4 Cable adopts special seal structure, the water could not enter inside motor, adopt and double mechanical seal mechanical seal. In a sealed motor shaft, sealing indoor 15 or 20 machine oil filling, forbid to fill, should take a certain space, in order to avoid motor running fever, machine oil expansion seal damage.


Mining flameproof submersible sand pump Working principle

Electric pump starts, turning on the power supply will produce a rotating magnetic field of the stator rotor rotation, so as to drive the impeller rotation. Due to the blade centrifugal effect, with a lot of water flow velocity and high pressure water pipe by the volute, ascend to the height of the ideal.
