As one of the core equipment of Isuzu fire trucks, fire pumps play a key role in extracting and transporting water to the fire scene. The high-power fire pump equipped on Isuzu fire trucks has powerful water pumping and water delivery capabilities, and can quickly provide a large amount of fire-extinguishing water in different scenarios. The fire pump uses an efficient water pump system to draw water from a water tank or an external water supply source. While the vehicle is moving, it sprays a powerful water flow through fire hoses, sprinklers and other equipment to extinguish the fire. The existence of fire pumps greatly improves the fire extinguishing efficiency and combat capabilities of fire trucks, and can quickly respond to fires, curb the spread of fires, and protect people's lives and property safety. The stable operation and reliability of fire pumps provide continuous water supply for fire scenes and greatly improve the ability and mobility of fire fighters to respond to fires. Therefore, the fire pump is of irreplaceable importance to Isuzu fire trucks and is one of the key equipment to ensure the smooth progress of firefighting work.

Let’s learn more about the fire water pump：

For low-pressure water tank Isuzu fire trucks with parallel pumps, if low-pressure water supply is used, the usage method is the same as that of low-pressure water tank fire trucks. If medium-pressure water supply is used, when the pump is running at low speed, switch the series-parallel conversion handle from the "parallel" position at startup to the "series" position, and adjust the throttle so that the water pressure and flow rate meet the requirements of the water gun or the medium-pressure soft Requirements for pipe reels and medium pressure water guns. It should be noted that when converting between "parallel" and "series" on the series-parallel conversion handle, the pump speed must be reduced first, otherwise the forced conversion may damage the structural parts of the pump.

For low-pressure water tank Isuzu fire trucks with tandem pumps, if only low-pressure water supply is used, the usage method is the same as that of low-pressure water tank fire trucks. If you only use medium-pressure water flow, you do not need to open the low-pressure water outlet. Instead, you only need to open the valve on the connecting pipe between the low-pressure pump and the medium-pressure pump, then open the valve on the medium-pressure outlet pipe or the medium-pressure hose reel valve, and adjust the throttle. , so that the water pressure and flow rate meet the requirements of the water gun or the requirements of the medium-pressure hose reel and medium-pressure water gun. If you want to use medium and low pressure together, open the low-pressure outlet valve, the valve on the connecting pipe between the low-pressure pump and the medium-pressure pump, the valve on the medium-pressure outlet pipe or the medium-pressure hose reel valve at the same time, adjust the throttle, and make the water pressure , the flow rate meets the requirements of the water gun or the requirements of the medium-pressure hose reel and medium-pressure water gun.

For high and low pressure water tank Isuzu fire trucks, if only low pressure water supply is used, the usage method is the same as that of low pressure water tank Isuzu fire trucks. If you use a high-pressure hose reel alone, you do not need to open the low-pressure water outlet. Instead, you only need to open the valve on the connecting pipe between the low-pressure pump and the high-pressure pump, open the high-pressure hose reel valve, and adjust the throttle to ensure that the water pressure and flow rate meet the requirements of the high-pressure hose reel. Requirements for pipe reels and high-pressure water guns. If you want to use high and low pressure together, open the low-pressure outlet valve, the valve on the connecting pipe between the low-pressure pump and the high-pressure pump, and the high-pressure hose reel valve at the same time. Adjust the throttle so that the water pressure and flow rate meet the requirements of the water gun and the medium-pressure soft hose. Requirements for pipe reels and high-pressure water guns.
