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.

    1. The weight of the pipeline should not be borne on the pump, otherwise the pump will be easily damaged.

      2. The pump and motor are of integral structure. The pump and the motor are an integral structure. It is calibrated by the manufacturer at the time of shipment, so there is no need to adjust the contract when installing it. This makes installation very easy.

      3. The foot bolt must be tightened during installation. The pump should be inspected at regular intervals to prevent it from loosening. To prevent the pump from vibrating violently when starting up and affecting the performance of the pump.

      4. Before installing the pump, check carefully whether there are any hard objects (such as stones, iron sand, etc.) in the flow channel of the pump that may affect the operation of the pump, so as to avoid damaging the overflow parts when the pump is in operation.

      5. For easy maintenance and safety in use. Install a regulating valve on the pump’s throttle and a pressure gauge near the pump’s throttle, and for high head pumps. To prevent water hammer. A check valve should also be installed in front of the outlet gate valve to cope with sudden power failure and other loss of power accidents, thus ensuring that the pump operates under suitable working conditions and increasing the service life of the pump.

      6. The pump is used in suction range situations. It should be equipped with a bottom valve, and the pipeline should not have too many bends in the mouth of the flume, and there should be no water leakage or air leakage in the same inch. To avoid affecting the suction performance of the pump.

      7, in order not to make impurities burst into the pump and block the flow channel to affect the performance. A filter should be installed in front of the pump’s flume.

      8, the installation of pipeline bary for the rotation of the pump rotor parts, should be no grinding sound or jamming phenomenon, otherwise the pump should be disassembled to check the reasons.
