How to solve the problem of insufficient flow of diesel engine fire pump group
The problem of insufficient flow of diesel fire pump sets may usually be caused by a variety of factors. Here are some possible reasons and corresponding solutions, presented in a clear and point-by-point manner:
1. Too high head
Problem description: When the head of the diesel fire pump is set too high, it may cause insufficient flow.
Solution: Adjust the head to match the actual needs.
2. Pipeline problem
Problem description: The pipeline is too long or has right-angle elbows, which may increase the resistance of fluid flow and cause insufficient flow.
Solution:
Shorten the length of the pipeline.
Change the curvature of the pipeline and reduce right-angle elbows.
3. Filter and pipeline blockage
Problem description: Garbage objects in the filter or pipeline may cause fluid flow obstruction.
Solution:
Check and clean the filter.
Remove garbage objects in the pipeline to ensure that the pipeline is unobstructed.
4. Motor problem
Problem description: There may be problems with the motor wiring, switch, etc., affecting the normal operation of the pump.
Solution:
Check whether the motor wiring is safe and whether the switch contacts are tight.
Repair or replace if necessary.
5. Impeller and impeller cover problem
Problem description: The friction between the impeller or impeller cover and the motor stator and rotor may increase the resistance of the pump.
Solution:
Check whether the impeller and impeller cover, motor stator and rotor are in contact.
If necessary, adjust or replace.
6. Other possible causes and solutions
The speed is too low: Check whether the motor wiring, voltage, etc. are normal.
The suction head is too high: Check the existing net pressure head and increase the suction head if necessary.
The impeller or pipeline is blocked: Check and clear the obstacles in the impeller and pipeline.
The motor is not rotating in the right direction: Check and adjust the rotation direction of the motor.
The impeller gap is too large or the impeller is damaged: Check and adjust the impeller gap, and replace the impeller if necessary.
