Fire pumps are the heart of the whole fire fighting system, and it is vital to start quickly and run continuously and reliably to pump fire water. Select a reliable quality fire pump, as well as daily maintenance in the firefighting work is vital, fire pumps in daily use, will often encounter a variety of common problems, such as vibration, abnormal noise, high temperature and a series of problems, today I will talk with you, why the fire pump will be hot, and we should respond to the measures.
We all know that the fire pump has a cooling system, divided into manual and automatic, its working principle is to control the heat exchanger heat dissipation capacity through the control of the ball valve. The engine cooling system of diesel fire pump adopts double closed-loop heat exchanger. The cooling water is controlled by ball valves from the pump outlet pipe to the heat exchanger so that the body cooling water temperature is between 85 and 95℃. If the water temperature is too high, the opening of the ball valve can be increased to increase the heat dissipation capacity of the heat exchanger, and vice versa, the opening of the ball valve is closed. Automatic control of the fire pump set, in the heat pipeline and the ball valve parallel to increase a solenoid valve. The solenoid valve is more temperature automatic switch, after 20 seconds the water temperature of diesel engine still exceeds 95°c, the automatic control system will issue an audible and visual alarm, and the staff will go to the scene to check the reason.
After understanding the working principle of the cooling system of the fire pump, we just need to know the diesel engine fire pump temperature is too high for several main reasons, in the future use of maintenance process, in the encounter of such situations, we can easily troubleshoot the problem, the simple problem can be repaired by themselves. Fire pump overheating mainly has the following possibilities.
1: diesel engine fire pump running for a long time can easily lead to overload operation. Therefore, in the operation of the fire pump, it is necessary to pay attention to the fact that we should avoid the diesel engine to run at high speed and overload for a long time.
2: The oil radiator of the diesel engine fire pump is blocked by foreign objects, causing poor heat dissipation. When the blockage is found, we only need to clear the blockage, and the problem can be solved.
3: The cylinder of the diesel engine fire pump leaks, and the high temperature gas enters the oil sump and heats the oil in the sump.
4: The cooling fan of the air cooler of the diesel engine fire pump rotates too low, which reduces the cooling intensity and makes the diesel engine body temperature rise.
5: The oil temperature adjustment switch of the diesel engine fire pump is not correctly positioned.
Check whether there is a problem with the above parts, basically you can check out the cause of high fire pump temperature. In the daily maintenance, zjbetter remind everyone that we must run and overhaul regularly, so as not to make it difficult to run in emergencies where sudden conditions occur!
