KXJ-80/660S flameproof and intrinsically safe pumps water level controller (hereinafter referred to as controller) for hazardous explosive gas and coal dust in coal mine underground pump automatic control, and ensure that water automatically Qidong, anhydrous automatically stop the pump. Reduce the labor intensity and reduce the failure rate of the pump to extend the mine life of the pump. 
 Second, characteristics: 
 Controller manual and automatic, along with the overload, phase failure, short circuit, main circuit leakage blocking and voltage protection, the controller can replace QQBZ-80-type flameproof vacuum electromagnetic starter. As a three-phase AC 50HZ, voltage 660V point source, can look into mine 55KW pumps used alone as a starter. 
 Explosion-proof type controller with the main structure of flameproof di, water level control section using intrinsically safe explosion-proof type ib, explosion-proof type is Flameproof and Intrinsic Safety. The explosion marked as Exd (ib). 
 Third, the working conditions: 
 (1) Operating ambient temperature is generally 0 - 40 degrees; 
 (2) not more than 2000 meters above sea level, atmospheric pressure 80 - 110KPa; 
 (3) air relative humidity of 95% (+25); 
 (4) pollution level 3; 
 (5) In grade 3 there is pollution, methane, an explosive mixture of mines; 
 (6) no obvious place to shake and vibration; 
 (7) and the installation of vertical tilt does not exceed 15 degrees, the water level probe is mounted vertically. Mobile
