Introduction

An overview,
Developed by our company under suction BQW series of mining flame-proof submersible pumps, adopt strict isolation measures, and the coal ministry has review inspection approval, apply to contain gas or coal dust explosion hazard gas mine, in the mining face and roadway, bottom hole water, local water, puddles, row containing the cuttings, coal, sand and other solids used in sewage. For diving flame-proof motor three-phase asynchronous motor, cover an area of an area small, easy installation and use, flame-proof and reliable, long life.
Second, using the environment and working conditions
Environment and conditions of use:
1, power frequency 50 hz, rated voltage 380 v or 660 v three-phase ac power supply.
2, the particle size of solid particles in water, no more than 15 mm.
3, the volume of solid impurities in water than the average no more than 2%.
4, medium temperature does not exceed 40 ℃.
5, by pumping liquid pH value of 4 to 10.
Three, structure features
Within 1. BQW series under suction type mining flameproof submersible pumps, diving flame-proof three-phase asynchronous motor and a sewage pump is composed of two parts. A pump body straight, at the bottom of the motor and its middle is equipped with reliable mechanical seal, can effectively prevent the cooling fluid in the motor and the pumping medium, the exchange between the cooling performance is good, guarantee the electric pump run reliably for a long time.
2. The motor winding for polyethylene water resistant nylon sheathed electromagnetic wire. 10 motor sealed inner cavity perfusion machine oil or 25 # transformer oil (for pumps, vertical submerged on bearing is limited, can not fill), with the centripetal ball shaft motor, easy tear open outfit, easy maintenance.
3. Small flow for closed type centrifugal pump impeller structure, used in mine excavating surface drainage, the central warehouse high lift water drainage: big flow for shuangliu non-clog pump impeller or mixed flow structure, used in sewage pumping high impurities in mines.
4. Electric pump design full consideration without blocking this crucial question, impurity particles through good performance.
5. Electric pump structure is built-in type, by pumping liquid discharge by motor, motor parts can work long time above the water.
