Cause of overcurrent of single stage double suction pump

Double suction pump will appear in the operation of this imagination of supercurrent, and what is the reason for this phenomenon?

1) The pump running speed is too high to make the motor overload operation, resulting in the phenomenon of supercurrent, should take relevant measures to reduce the speed of double suction pump running;

2) The single-stage double-suction pump supporting power is lower than the actual supporting power, which increases the load of the motor, and replaces the high-power supporting motor as soon as possible to reduce losses;

3) If the bearing appears or the shaft is bent, it should be checked immediately whether the pump shaft and bearing are faulty, and if there is a corresponding replacement;

4) The pressure of the packing gland is too tight, and the corresponding relaxation is carried out;

5) In the process of single-stage double-suction pump assembly, the gap between the pump coupling and the motor coupling is too large or they are different, the pump coupling can be adjusted accordingly;

6) The head of the model selected in the selection is much higher than the actual working condition, resulting in the phenomenon of overcurrent, which can be adjusted by installing the outlet valve;

7) The motor is unstable when the motor is disabled for a long time, which can make the motor run for a period of time and gradually stabilize.

When the single-stage double-suction pump appears the phenomenon of overcurrent, it should be stopped immediately to check the pump group and solve it in time, so as to ensure that the pump unit will not fail and can operate effectively.
