What to do if the diesel engine fire pump head is too high
When the head of the diesel engine fire pump group is too high, the following methods can be used to solve the problem:
1. Choose a suitable fire pump:
When purchasing or selecting a fire pump, you must consider the actual needs and the use environment and choose a suitable pump type. Make sure that the pump's head, flow rate and other parameters meet the actual needs.
For the installed fire pump, if there is a problem with the head, you can consider reselecting the pump type and replacing it with a pump that is more suitable for the actual needs.
2. Adjust the pump's use parameters:
If the installed fire pump has a too high head, you can solve the problem by adjusting the pump's use parameters. For example, appropriately reduce the pump's speed, adjust the valve opening of the inlet and outlet pipes, etc., to meet the actual water pressure required.
When adjusting the parameters, it is necessary to refer to the pump's performance parameters and actual use status to ensure that it will not affect the normal operation of the pump.
3. Check and adjust the pipeline system:
Check whether the inlet pipeline has problems such as excessive resistance and unreasonable design, and make corresponding adjustments and optimizations.
Ensure that the inlet water level is not lower than the center line of the pump to avoid increased suction resistance.
4. Other possible solutions:
If the high head of the fire pump is caused by improper pump design or too small water flow, you can consider reducing the water flow rate, increasing the number of pumps, or using other technical means to reduce the head.
If none of the above methods can solve the problem, it is recommended to contact a professional fire pump supplier or maintenance personnel for more in-depth diagnosis and repair.
