What are the common problems of diesel emergency fire pump?


No matter what brand the diesel engine emergency fire pump is, in the process of long-term use, some problems will inevitably occur. For some common problems, the operator should know the cause and the countermeasures. So, what are the common faults in the use of diesel emergency fire pumps?

1. Cannot start

Sometimes the diesel engine emergency fire pump will fail to start. At this time, you must check the connection of the power plug in time to see if the connection is firm, and at the same time check whether the switch is in tight contact. If there is an open circuit or poor contact, you must Repair in a timely manner.

2. Insufficient flow

Sometimes the diesel engine emergency fire pump will have insufficient flow. This problem is likely because the lift is too high, or the pipeline is too long, or the pipeline has a right-angle bend. These factors will lead to insufficient flow. Therefore, the lift should be adjusted in time, the pipeline should be shortened, and the curvature of the pipeline should be reduced. At the same time, it should also be checked and excluded from the filter screen and the pipeline. If there is any blockage, it should be removed in time.

3. Motor overheating

During the operation of the diesel engine emergency fire pump, if the motor overheats, it is best to check the wiring and switches in time to see if there is a short circuit, and check the impeller and impeller cover, and check whether there is friction between the motor stator and the rotor. The above problems exist, and obstacles must be eliminated in time.

4, can not absorb water

When the diesel engine emergency fire pump fails to absorb water, it is probably because there is air in the pump body, or there is air accumulation in the water inlet pipe. At this time, the air must be removed, and the water must be pressed up first, and then the pump Fill your body with water, and then turn it on again. At the same time, it is also necessary to check whether the check valve is tight, and whether there is air leakage in the pipeline joints. If air leakage is found, after disassembly, apply lubricating oil or blend paint to the joints, and tighten the screws at the same time. In addition, the oil seal ring of the diesel engine fire pump should also be checked. If it is worn, it must be replaced in time.

All in all, as an operator of a diesel emergency fire pump, you must be familiar with these common problems in the process of operation. When a problem occurs, you must find the cause in time and come up with solutions
