Since the operation of the electric water pump is inseparable from electricity, and the power supply is often cut off at the scene of a fire accident or the power supply is automatically closed due to the fire, even if we are equipped with a dual power supply switching device, it is really impossible to ensure that the power grid must be normal when the fire alarm signal comes.
Therefore, starting and running a diesel engine fire pump completely disconnected from the grid becomes the preferred equipment for backup fire protection facilities! The driving power of diesel engine fire pumps is completely different from that of electric water pumps, so their daily protection and treatment are also different in many places! The characteristics of diesel engine fire pump: The biggest difference between diesel engine fire pump and electric water pump is that it has its own independent power supply system – storage battery. Therefore, the start and operation of diesel engine fire pump can be completely separated from the mains.

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.

Diesel engine fire pump unit is a kind of pump equipment that is widely used in fire protection, and it is more suitable for mobile work in fire pumps. In fact, it is driven by a diesel engine connected to the pump head of the fire pump. Compared with motor drive, it can be used in the field, mines, and places lacking power supply. It is also called a diesel engine pump or a diesel engine fire pump unit.

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.
