The automatic assembly line tank production process is divided into: blanking, automatic plate welding, head spinning forming, one-time roll forming of the tank body and other domestic advanced production processes. The tank material is mostly produced from high-quality carbon steel plates.
For special purposes, imported Korean 304 stainless steel can also be used according to customer needs. The tank volume is "3 cubic, 4 cubic, 5 cubic, 6 cubic, 8 cubic, 10 cubic, 12 cubic, 15 cubic, 20 cubic, 25 cubic, 30 cubic".
The engine drives the gearbox, and the power take-off installed on the gearbox drives the sprinkler pump. The sprinkler pump generates power to spray the liquid inside the tank through the pipe network. Working range: Self-priming height: ≤7m, sprinkler width: ≥14m, maximum range: ≥28m; can be adjusted to direct rush, heavy rain, light rain, drizzle, range ≥30m; can also be adjusted to mist, range ≥15m.
Sprinkler truck water pump:
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 with an upward-curved elbow and then a horizontal pipe. Pipes and quick connectors, 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. Connect 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 pipeline 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 circulates multiple times until the gas in the suction pipe is drained out. Filled with liquid, the self-priming process is completed, and 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. Operation.
