Structural Characteristics And Application Scope Of Explosion-proof Sand Discharge Mining Pump

Jan 03, 2025

Explosion proof sewage and sand discharge submersible mining pump is an electric drainage and irrigation equipment that combines a pump and an electric motor. Next, let's talk about the structural characteristics and application scope of explosion-proof sand discharge mining pumps.

1, Structural characteristics of explosion-proof sand discharge mining pump

It can operate continuously underwater for a long time and is equipped with an electric pump. Water flows through the interlayer of the electric motor, effectively extending the service life of the electric pump;

External electric pump, with a double channel large overcurrent structure for the impeller, operates smoothly, has strong discharge capacity, is anti winding, and has no blockage phenomenon;

The electric motor adopts a Y-shaped dry-type explosion-proof three-phase asynchronous motor, which has the characteristics of high starting torque, good operating performance, low noise, small size, light weight, easy maintenance, as well as excellent explosion-proof structural performance and high protection level;

The electric pump adopts an O-ring rubber seal as the static seal, which has good structural performance. The rubber vulcanization curve control technology is used to ensure the quality and sealing performance of the O-ring in terms of moisture resistance and aging resistance;

The dynamic seal adopts two sets of mechanical seals with oil chamber isolation protection, effectively providing lubrication for the rotating friction pair, forming a fluid film lubrication protection, and releasing the heat accumulated during the movement process, thereby extending the service life of the mechanical seal and ensuring the sealing performance;

The fluid components of the electric pump are made of wear-resistant alloy cast iron, and the water pump part adopts fluid mechanical design and balancing technology, effectively extending the service life of the electric pump.

2, Application scope of explosion-proof sand discharge mining pump

Suitable for use with water pumps in environments containing explosive gases such as methane or coal dust, underground mining faces and tunnels with explosive hazards.

Widely used for automated drainage of coal mine shafts, inclined shafts, and loose coal slurry at the bottom of the shaft.
