Water pump head reduced, may be these several reasons
1, impeller inflow channel blockage
First of all, the most intuitive problem, check whether the impeller is stuck in the main blockage, if so, timely cleaning can break theproblem.However, filtering bias can be added to the front of the pump bay to avoid the impeller runners being blocked again, If necessary.
2 、 Inside leakage
When the gap between the connection points of colorful corridor in the pump is too large, it’ll beget the pump to blunder, performing in a drop in discharge pressure. When this problem occurs, dismembering and form should be carried out.
3 、 Cavitation
still, performing in the pump bay pressure is lower than the impregnated brume pressure of the pumping medium, it’ll form cavitation, If the bay pipeline system has no blockage or the bay stopcock opening is too small. At this time, the blockage should be cleared or the bay stopcock should be opened wide, or the liquid position of the bay pool should be increased.
4 、 drop in rotational speed
Check whether the speed of the pump is reduced because of certain factors, the speed is commensurable to the head, if the speed of the problem, check the reasons, reasonable results.
5 、 Motor reversal
Observe the steering of the pump, if the steering is reversed, exchange the two cables on the outstations of the motor.
