Recently, Shenhua Shendong Coal Group Yujialiang mine self-developed timing pump and successfully put into use.
Timed pump is a mechanical timer added to the control loop, the staff can be based on the amount of water accumulated, combined with the pump rated displacement, calculate the time required to pump water, and through the timing controller knob set the pumping time , When the timer ends automatically stop working pump. In the case of water particularly large, need long-term open, simply turn the timing control device to the normally closed position, the pump will always be in working condition.
At present, the invention has been put into operation in the mine, effectively reducing the workload of the staff, but also put an end to the pump in a state of vacuum pump damage caused by the phenomenon, by the staff alike.
