The flow rate of ordinary diesel pump is generally low, and sometimes it can not meet the requirements of customers. Nowadays, the diesel pump with large flow rate has been developed. It uses double suction ports, which is twice the flow rate of ordinary diesel pump. Moreover, the structure is more reasonable, the NPSH is small, and it is more durable,

This is a large-flow diesel fire pump. Diesel fire pumps are suitable for high-lift and high-flow fire-fighting environments. Because the diesel engine has strong power, it can drive a large pump. The large pump is what we often call a high-lift and high-flow centrifugal pump. , and can maintain the stability and work efficiency of the equipment.

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 biggest difference between diesel engine fire pump and electric water pump is that it has its own independent power supply system – battery. Therefore, the start and operation of diesel engine fire pump will not completely depend on city power.

The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference.

As environmental concerns become more prominent, there is growing interest in environmentally friendly firefighting pump options.

Generally speaking, we recommend that where natural ventilation is used to install diesel engine fire pumps, there must be vents and exhaust ports of sufficient size, and the position of the vents ensures that there is enough fresh air to supply the diesel engine for combustion within the temperature limit. Of course, the water supply radiator can also be used to take away the heat of the circulating cooling water and the heat emitted from the surface of the unit. If the space cannot meet the requirements of natural ventilation and cannot effectively dissipate heat, it is recommended that you adopt forced ventilation, install an intake fan and an exhaust fan at the vent, and choose a location that can provide enough cold air for the diesel engine and take away the machine room hot air inside. Generally speaking, the air intake of the unit should be 6-7 times that of the diesel engine. Only in this way can normal ventilation be ensured and the operating efficiency of the equipment can be improved.

In addition, it must be fixed firmly so that the entire unit can be supported to ensure that the unit is in a horizontal state and absorb vibration. Generally speaking, the foundation of the unit adopts a concrete structure. The length and width are 150-250mm on one side of the length and width of the unit chassis, and the depth is 300-600mm. The height of the anchor bolts should be about twice the bolt diameter. And there should be a 750mm channel on both sides and front of the unit to facilitate the operator’s inspection and general maintenance.
