It can be used in independent fire water supply systems, and can be used in fire protection and living shared water supply systems. It can also be used in construction, municipal, industrial and mining, water supply and drainage, ships, field operations and other occasions .

Three start-up functions for diesel engines:
1. Manual start function: manual and automatic interlocking can be completed through the transfer switch, and the manual start function can be realized:

2. Automatic manual function: allow to start three times. If the startup fails for three times, it will issue a “startup failure alarm” and automatically exit the startup state. After a successful startup, the time from startup to rated load is 5-10-15S (depending on the unit capacity);

3. Emergency manual direct start function: When the automatic control device fails, the emergency manual direct start function can be realized.

The engine cooling system of the diesel engine fire pump adopts double closed-loop heat exchangers. The system has the advantages of high cooling efficiency and little influence on the ambient temperature of the pump room. The cooling water flow direction is controlled by a ball valve from the pump outlet pipe to the heat exchanger, so that the cooling water temperature of the body is between 85 and 95 °C. If the water temperature is too high, the opening of the ball valve can be increased, the heat dissipation capacity of the heat exchanger can be increased, and the water temperature of the engine cooling water can be reduced. On the contrary, the opening of the ball valve can be closed to increase the water temperature of the engine cooling water.​​
Diesel engine fire pump sets, such as automatic control fire pump sets, add a solenoid valve in parallel with the ball valve in the heat pipe. Under normal circumstances, the solenoid valve is closed, and the cooling water can meet the engine cooling requirements through the gate valve. When the engine cooling water temperature exceeds 95°C, the solenoid valve will automatically open to increase the cooling water flow and reduce the engine cooling water temperature. After 20 seconds, when the water temperature of the diesel engine still exceeds 95°C, the automatic control system will issue an audible and visual alarm and call the staff to the scene to check the cause.

The diesel engine fire pump has compact structure, small size and beautiful appearance. Its vertical structure determines that the installation area is small, and its center of gravity coincides with the center of the pump foot, thus enhancing the running stability and service life of the pump. The horizontal direction simplifies the connection of the pipeline, the pump rotor has a small winding, stable operation, low vibration, low noise and long service life.

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. Because diesel fire pumps are not omnipotent, there will be some problems in daily use, so when choosing equipment, we must pay attention to whether the quality of the equipment meets the national standards. As fire equipment, all kinds of equipment must be To ensure performance, avoid affecting use in disaster situations and delaying rescue.

The fire pump is usually equipped with a local control cabinet. The control cabinet does not have a transfer control switch for automatic and manual conversion, but the automatic control loop leaves start and stop contacts, which are connected to the fire alarm system control module. In addition, according to the relevant regulations, the system using the bus linkage control should also be set in the fire control room with buttons that can directly start and stop the pump.
When the fire alarm system receives the signal of the fire hydrant start pump button, the control module automatically starts the fire pump and collects its feedback signal.

The fire pump is part of the water supply of the fire sprinkler system and can be powered by electricity or diesel. The inlet of the pump is connected either to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake). The pump supplies water at higher pressure to the sprinkler system risers and hose risers.
Fire pumps generally use three driving forces, including diesel engines, gasoline engines and electric motors. Gasoline engines are commonly used in portable fire pumps and light duty firefighting. Electric motors are the most widely used driving force for fire pumps and are both efficient and convenient.

After receiving the fire/pipe network pressure/power failure/other start signals, the diesel engine fire pump can automatically start and enter full load operation within 5 seconds. The battery can be automatically charged by the main power supply or the diesel charging motor to ensure the smooth start of the equipment; automatic alarm protection for low oil pressure, high water temperature and other faults of the diesel engine, overspeed alarm and shutdown; the diesel engine fire pump is in a hot engine standby state to ensure emergency work.
