The power take-off of a water sprinkler truck is one of the important components of the vehicle. Without it, the water sprinkler function cannot be used normally. Not only in water sprinkler trucks, but also in other fields of professional vehicles, the role of the power take-off cannot be underestimated, such as oil trucks, aerial work platforms, high-pressure cleaning vehicles, road sweepers, sewage and feces suction vehicles, etc. In these vehicles, power take-off is widely used.

So, what is a power take-off? What is the function of the power take-off for a water sprinkler truck? The following is a detailed introduction for you.

1. What is a power take-off

The power take-off is a set of variable speed gears, also known as a power output device. It is generally composed of a gearbox and a clutch. It is connected to the transmission by gears and to the lift pump by an shaft. It is a separate gear in the transmission. When this gear is engaged and the accelerator is pressed, the lift pump can start to operate. The water sprinkler truck lift pump is a hydraulic device that lifts the truck body and realizes the self-unloading function. Special vehicles that require additional power, such as dump trucks, fire engines, cement mixers, and refrigeration equipment, obtain power through power take-off devices. The power take-off is an additional device installed on the outside of the transmission (for cement mixers, it is on the clutch housing), and it acquires power from a certain gear in the transmission. The connection or disconnection of this power is achieved through an electromagnetic valve in the driver's cabin. The high-pressure oil pump is driven by the power take-off to supply the dump truck. Drive the water pump to supply power to the fire engine; Drive the compressor to supply the refrigeration vehicle; Drive the hydraulic motor to rotate the stirring tank.

2. The function of the power take-off of the water sprinkler truck

The main function of the power take-off of the water sprinkler truck is to provide power for the water pump, enabling the water sprinkler truck to perform water sprinkling operations normally and providing all power sources except for driving.
