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.

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.

Now the general diesel engine fire pump set is powered by imported or domestic Cummins, Wuxi Power Engine Factory and other diesel engines produced by large-scale key enterprises in the internal combustion engine industry at home and abroad, through highly elastic couplings or diaphragm couplings produced by professional manufacturers. The engine is directly connected with the water pump, and the power of the diesel engine can reach 880KW. It can be equipped with water pumps of different lifts and flow rates for customers to choose and use according to different needs.

At the same time, it can be connected with the customer’s automatic fire alarm device or the fire control system control cabinet produced by our factory to realize the function of remote monitoring.

Fire pumps are used in the equipment of the fire protection system. Their function is to increase the pressure to supplement the water source, so as to achieve the purpose of extinguishing the fire. Moreover, the equipment adopts high-tech means and introduces advanced technology, which has incomparable advantages over other products.

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.

The advantage of the diesel engine fire pump is that when a fire breaks out, the power supply fails, and the electric fire pump set cannot be put into use normally, the diesel engine fire pump set can be put into operation automatically to ensure the normal fire fighting. Compared with the electric fire pump set, the second advantage is that it does not need long-term investment in power supply, saving the mains power supply transformer and normal expenses. Diesel engine fire pumps are equipped with various automatic functions to meet customer requirements, ensure long-term normal standby status of the equipment, and put it into fire fighting work at any time.

1. Natural ventilation When setting up and arranging diesel machine fire pumps, it’s first necessary to consider adequately sized ventilation openings and exhaust openings, and secondly, to insure that there’s enough fresh air to supply diesel machine combustion within the temperature limit. In this way, the heat of the circulating cooling water can be taken down by the water force radiator to take down the heat radiated from the face of the unit.

2. Forced ventilation when the natural ventilation conditions can not be met, forced ventilation can be espoused. Inlet suckers and exhaust suckers can be installed at the reflections. The addict specifications and the position of the air bay and outlet in the machine room should be named to give enough cold air for the diesel machine. At the same time, the hot air in the pump room is taken down, and the small air input volume of the unit needs to be about 6- 7 times that of the diesel machine air input.

The main heat dissipation methods of diesel engine fire pumps can be divided into two types: wind heat dissipation and water heat dissipation. According to the two heat dissipation principles, the water heat dissipation system has uniform heat dissipation and good heat dissipation effect. The relative price is also relatively low, so most of the diesel engine fire pumps mainly use water for heat dissipation. Wind heat dissipation can be divided into two types: natural wind and forced wind. Natural wind uses the airflow coming in from the machine in motion to directly cool the cylinder head, cylinder block and other parts; The airflow at the place increases the cooling rate and area. The principle of water heat dissipation is to use water or antifreeze as a cooling medium to take away the heat of the high-temperature parts of the diesel engine fire pump engine to ensure the normal operating temperature of the engine.
