Diesel engine fire pumps are usually used as a backup facility, and will only start automatically when the electric water pump fails or the power is cut off when the fire signal comes. When equipped with an ultra-low pressure pump starting device, the matching electric pump control cabinet should also be equipped with an ultra-low pressure pump starting device, and the lower limit of pump starting should have a certain pressure difference. Of course, it is also possible to design a control system that is more suitable for customer needs according to customer requirements.

1. The function of the diesel fire pump is very powerful. We can set the control time during use, such as: preheating, pre-lubricating or timing start. The use of high-tech has made some complicated and time-consuming things easier in the past. The preheating setting greatly reduces the preparation time for rescue, allowing firefighters to rescue the first time. In the face of disasters, time is money and time. is life.
2. The head and flow can be controlled by adjusting the speed of the engine, and the height and size of the water flow become easier to control. When the nozzle is in a stable state, by controlling the engine, we can accurately spray the water source at the fire point to extinguish the fire, which also reduces the difficulty of rescue for firefighters.

Power surges or electrical disturbances can impact the operation of electric fire pumps. Proper surge protection measures, such as surge suppressors and lightning protection, should be in place to safeguard the electrical components of the fire pump system.

Diesel engine fire pumps are relatively common in life, and their performance requirements are relatively high. In ordinary use, more attention should be paid to maintenance, so as to prolong the service life of the pump.
