Model Description
Technical parameters
1.The altitude should not exceed 2000 meters;
2.The operating environment temperature -5° C ~ 40 ° C;
3.The relative humidity should not exceed 95% at 25°C;
4.In an environment with a methane explosive mixture in the mine;
5.The installation inclination with the vertical plane does not exceed 15 °;
6.Where there is no significant shaking or impact;
7.In gas and steam environment without obvious damage to insulation;
8.At the place without dripping;
9.Pollution level: 3 ;
10.Installation category: III.
Enable the automatic activation of the water pump and its automatic shutdown in the absence of water (or through a counter control). This system alleviates labor intensity, reduces the pump's failure rate, and prolongs the operational lifespan of the mining electric pump.
