KMFP-5 Valve Group Negative Pressure Automatic Slag Drainer

There is a large amount of water and sediment in the coal mine gas pipe pumping system, which often causes pipeline blockage, poor pumping and drainage, increases the negative pressure of the system, increases the torque of the pumping motor, greatly reduces the pumping efficiency, and seriously threatens the safety of production. Section 5.4.6 of the Code for Coal Mine Gas Pumping (AQ1027-2006) points out that “water dischargers should be placed at the pumping drill site, pipeline bends, low-lying areas, sudden temperature changes and appropriate distances along the pipeline”; Section 5.5.5 “Water dischargers shall be provided in the pipes near the station building ……”.
