water tank truck working video, also known as multi-function greening Spray sprinkler truck. It is used to clean roads, sanitation, dust, watering, spraying pesticides, etc. of urban roads, large factories, troops, gardens, etc., in order to beautify the environment. At the same time, it can be used for temporary emergency fire fighting sprinklers. Each sprinkler 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 and sprays the liquid inside the tank through the pipe network. Self-priming height: ≤7m, sprinkling width: ≥20m, maximum range: ≥28m; can be adjusted into a column, range ≥28m; can also be adjusted into a fog, range ≥5m.
Before spraying and after spraying, the front is equipped with a duck-shaped nozzle or a round head punch, the rear is equipped with a cylindrical sprinkler nozzle or a shower head nozzle, and a working platform at the rear is equipped with a high-pressure water gun. The rear can also be equipped with 8 nozzles (optional) sprinklers are generally used to flush the street.
The basic composition of the sprinkler: anti-rust tank, power take-off, transmission shaft, special self-priming sprinkler pump, pipe network, spray outlet, working platform, second-class chassis.
Optional configuration of sprinkler: GPS, universal sprinkler, electromagnetic valve, pneumatic valve, visual operating system, external power, medicine tray.
The sprinkler uses the engine power of the car to drive the on-board sprinkler pump through the power take-off, add water to the car from the water inlet or transport the water in the tank to each sprinkler through the pipeline, so as to achieve various functions.
Before the sprinkler pump works, the liquid in the pump must be higher than the pump shaft, so the pump inlet must be connected with an upward bent pipe and then a horizontal pipe and a quick connector. The center line of the quick connector must be 300 mm above the center line of the pump shaft ; The inlet piping system must ensure that there is no air leakage; the suction head of the suction pipe must be submerged under 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 elbow.
The sprinkler pump adopts an externally mixed self-priming structure, and an appropriate amount of liquid should be stored in the pump. After the pump is started, the impeller rotates, and a negative pressure is formed at the inlet of the impeller. The gas in the suction pipe is mixed with the liquid in the pump, and enters the gas-liquid separation chamber through the pressure chamber. Due to the difference in the specific gravity of 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. After repeated cycles, the gas in the suction pipe is discharged and filled with liquid, completing the self-priming process. , The pump begins to infuse normally.
The sprinkler pump can function as water suction and pressurized drainage. The self-priming pump can directly suck the water from the pond into the tank, or directly connect the water injection from the fire hydrant on the city street and suck it into the tank for sprinkling.
