Sprinkler trucks are also called spray trucks, multi-function sprinkler trucks, landscaping sprinkler trucks, water tank trucks, and water trucks.
Sprinkler trucks are suitable for washing various road surfaces, trees, green belts, lawn greening, construction of roads, factories and mines, and high-altitude building washing. It has the functions of water sprinkling, dust pressing, high and low level spraying, pesticide spraying, guardrail washing, etc. It also has the functions of water transportation, drainage, emergency firefighting, etc.
Spraying truck, also known as multi-functional greening sprinkler truck. It is used for road cleaning, sanitation, dust prevention, watering, pesticide spraying, etc. on urban roads, large factories, military units, gardens and other units to beautify the environment.
It can also be used for temporary emergency fire sprinklers. Each sprinkler truck is equipped with a dedicated fire-fighting interface. The engine drives the gearbox, and the power take-off installed on the gearbox drives the sprinkler pump. The sprinkler pump generates the main power to spray the liquid inside the tank through the pipe network. Self-priming height: ≤7m, sprinkler width: ≥20m, maximum range: ≥28m; can be adjusted into columnar shape, range ≥28m; can also be adjusted into mist, range ≥5m.
It sprays from the front to the back, with a duck-shaped nozzle or a round head nozzle at the front, a cylindrical sprinkler nozzle or a shower head nozzle at the back, and a working platform at the back equipped with a high-pressure water cannon. Eight nozzles (optional) can be installed at the rear. Water sprayers are generally used for washing streets.
Water absorbing work
(1) The sprinkler truck should be as close as possible to the operating point and park.
(2) Open the side door of the walking platform box, take out the water-absorbing hose, and swing it backward without bending.
(3). Pump the water-absorbing hose into the water as deep as possible, ensuring that the end of the pipe is always less than 300mm from the liquid level during operation.
(4). Push the handle of the four-way valve until it is perpendicular to the ground.
(5). Put the transmission into neutral, then start the engine, disengage the clutch, pull the power take-off switch backward to put the power take-off into gear, and the pump starts running.
(6) The operator can pass the observation mirror on the upper part of the rear head. When the liquid level reaches the middle of the observation mirror, the driver should be notified, and colleagues should quickly pull the water suction hose away from the water or close the four-way valve.
(7) After putting away the hose, put it back into the walking box and close the side door.
(8) Drive the sprinkler truck away from the pumping location.
Spraying operations
(1) Pull the rear handle of the four-way valve parallel to the ground, open the ball valve you want to spray (front spray, rear spray, side spray, shower), then start the engine, put the transmission into gear, and turn the power take-off Pull the switch back to put it into gear and take power, then disengage the clutch, the pump starts to run, and starts sprinkling water.
(2) After the water in the tank is sprinkled, the driver should promptly push the power take-off control handle forward to disengage the gear and stop the sprinkler pump.
The sprinkler truck uses the power of the vehicle's engine to drive the vehicle-mounted sprinkler pump through the power take-off. It adds water to the vehicle from the water inlet or transports the water in the tank to each nozzle through pipes to achieve various functions.
Before the sprinkler pump works, the liquid inventory in the pump must be higher than the pump shaft, so the pump inlet must be connected to an upward-curving elbow and then a horizontal pipe and quick connector. The center line of the quick connector must be 300 mm higher than the center line of the pump shaft. ; The inlet piping system must be guaranteed to be airtight; the suction head of the suction pipe must be immersed in water to prevent air from being sucked into the water pipe; when the outlet pipe is connected to the pump outlet, the length of the straight pipe must be ≥ 200 mm before connecting the bent pipe.
The sprinkler pump adopts an external mixing self-priming structure, and there should be an appropriate amount of liquid in the pump. After the pump is started, the impeller rotates and a negative pressure is formed at the impeller inlet. The gas in the suction pipe mixes with the liquid in the pump and enters the gas-liquid separation chamber through the pressure discharge chamber. Due to the difference in specific gravity between gas and liquid, the gas is separated from the liquid and discharged from the outlet pipe. The liquid sinks in the gas-liquid separation chamber and undergoes multiple cycles until the gas in the suction pipe is drained and filled with liquid, completing the self-priming process. , the pump starts normal infusion.
The sprinkler pump can absorb water and pressurize drainage. The self-priming pump can directly suck water from the pond into the tank. It can also be directly connected to the fire hydrant on the city street to inject water and suck it into the tank for sprinkling operations.
The most common use of spray trucks is road cleaning, and we can also see spray trucks in large gardens. A spray truck is a type of sprinkler truck. It is mainly used for chemical spraying in green belts and large gardens on both sides of the road.
By type
1. Spray type.
2. Flush type.
3. Spray-rinse type.
According to use
Greening sprinkler truck, multi-function sprinkler truck, truck-mounted crane sprinkler truck, water truck sprinkler truck, fire sprinkler truck.
According to capacity
3-8 cubic meters sprinkler truck.
10-12 cubic meters sprinkler truck.
13-15 cubic meters sprinkler truck.
18-20 cubic meters sprinkler truck.
Sprinkler truck with more than 20 cubic meters.
According to emission standards
National V, National IV, National III, National II.
According to chassis
1.Automobile style.
2.Semi-trailer type.
3.Trailer mounted sprinkler truck.
(1) Car chassis and supporting pump maintenance should be carried out according to the corresponding operating instructions.
(2) The vehicle should be run-in according to the requirements of the vehicle manual before use.
(3) When transporting the vehicle for long-distance transportation, there should be fixed anti-skid devices on the front, rear, left and right sides of the vehicle, and there should be a gap of more than 200mm around the vehicle. If the vehicle is moving by itself, the front nozzle and rear sprinkler should generally be removed to prevent them from becoming loose and lost.
(4) Frequently check whether there is any blockage in each liquid outlet hole and mouth. If any blockage is found, it should be cleaned in time.
(5) After each shift of work, the oil stains should be cleaned, the pipelines should be rolled up neatly, the site should be cleaned, and the doors should be locked.
(6) If the vehicle is not used for a long time or is stored in winter, the remaining water in the tank, pump and pipelines should be drained. When stored, it should be parked in a carport and wiped clean to avoid exposure to the sun and rain.
Cleaning of the chassis of the sprinkler truck: The chassis closest to the ground must be messed up by mud and sand. Therefore, before cleaning other parts, we must first conduct a comprehensive cleaning of the chassis of the 10-ton sprinkler truck. After passing through a muddy road, the front and rear hub plates of the 10-ton sprinkler truck will be covered with yellow mud and small sand and gravel. When cleaning, you need to use a high-pressure water gun under the wheel hub plate. The water spray direction of the high-pressure water gun is toward the wheel hub plate, so that the dirt attached to the wheel hub plate can be effectively removed.
Cleaning of the paint surface of the sprinkler truck: After completing the cleaning of the chassis, we can clean the body of the 10-ton sprinkler truck. First, rinse the car paint surface from top to bottom with tap water in order to wash away the larger volume of sand and gravel on the car body. Use a towel and wipe gently from top to bottom of the car. Please note that the paint surface closer to the chassis must be wiped more carefully to prevent the car paint from being scratched by fine sand.
