Mine explosion-proof submersible pump is also called explosion-proof submersible pump. I believe most people don’t understand how to achieve explosion protection. Our company will give you the following explanation. The explosion-proof measures for mining explosion-proof submersible pumps are divided into two categories. The first category of measures is to allow explosions in the inner cavity of the motor, but must not spread to the surrounding medium.
The second type of measure is to take isolation measures between the conductive part and the explosive medium. Or to prevent dangerous sparks and localized heating of conductive parts that may come into contact with explosive mixtures.
The mining explosion-proof submersible pumps produced by our company are designed and manufactured strictly in accordance with the coal industry standards/"Explosion-proof Submersible Electric Pumps for Coal Mines" and the national executive standard of the Republic of China "Electrical Equipment for Explosive Gas Environments". The motor adopts Dry type explosion-proof three-phase asynchronous motor has the characteristics of large 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. It is suitable for It is used in conjunction with water pumps in environments containing dangerous explosive gases such as gas or coal dust, and in underground mining surfaces and tunnels with explosion risks.
1. This pump is suitable for draining sewage containing solid particles in environments with the risk of methane explosion, drainage of coal mines, drainage of inclined shaft construction, drainage of mines without water silos, drainage of mining working faces, and main drainage. Parallel well
Automatic drainage of coal bunkers at the bottom, automatic drainage of ponds, automatic drainage of water gushing in uninhabited areas, drainage of clear water bunkers, cleaning of silt, sand and floods, disaster relief and emergency drainage, etc.
