Mine flameproof submersible sewage pump, the pump and motor combination of power irrigation and drainage equipment. Its appearance, simple structure, good sealing performance, easy to install and use, and can be long-term continuous operation in the water, is widely used in coal mine shaft, inclined shaft and the bottom of the loose coal slurry automatic drainage. The following describes the structural characteristics of mining submersible pumps.
The electric pump and the impeller adopt the big flow structure of the double flow passage, the running is steady, the sewage capacity is strong, anti-winding, no clogging phenomenon, and the pump is easy to operate. And has a small size, light weight, easy to carry characteristics.
Each mine flameproof submersible sewage pump are strictly in accordance with the coal industry standard MT / T671-2005 "coal mine explosion-proof submersible pump", the Chinese Republic of national implementation of the standard GB3836-2000 "Explosive gas environment electrical Equipment "to design production.
The motor adopts Y type dry type explosion-proof three-phase asynchronous motor, which has the characteristics of big starting torque, good running performance, low noise, small volume, light weight and convenient maintenance, and good flameproof structure performance and high protection Grade, suitable for containing methane or coal dust and other explosive gas environment, there is an explosion of mine mining face and roadway and other places and supporting the use of pumps.
O-shaped rubber pump seal as a static seal, structural performance, the use of rubber vulcanization curve control technology to protect the O-ring anti-aging anti-aging quality and sealing performance.
Dynamic seal with two sets of mechanical seals, and oil chamber isolation protection, effective for rotating friction pair to provide lubrication, the formation of fluid film lubrication protection, while releasing the accumulation of heat in the movement process, thus extending the mechanical seal life, to ensure that The sealing performance. Pump fluid components made of wear-resistant alloy cast iron, pump part of the fluid mechanical design and balancing technology, effectively extending the life of the pump.
