sinotruk howo 18000l to 20000l water tank truck operation instructions:
The spray truck is equipped with a duckbill nozzle or a round head nozzle in the front, a cylindrical sprinkler nozzle or a shower head nozzle is arranged at the rear, and a working platform at the rear is equipped with a water gun. Eight nozzles can also be installed at the rear.
Special functions for spraying vehicles and greening spraying vehicles: multi-functional greening and sanitation, suitable for greening and sanitation of factories in urban communities, using high-power special sprinkler pumps with national leading quality. Front sprinkling (spraying), rear sprinkling, side spraying (shower), rear working platform, green sprinkling anti-aircraft gun mounted on the platform (the gun has heavy rain, moderate rain, drizzle, and fog can be adjusted), with suction pipe, with fire protection Connector, with self-flow valve, self-priming and self-draining, optional 20-meter greening spray reel, high-altitude operation, truck-mounted crane and other functions.
Operating system: The engine mainly drives the gearbox, and the power take-off installed on the gearbox drives the sprinkler pump. The sprinkler pump generates power and sprays the liquid inside the tank through the pipe network. Working range: self-priming height: ≤7m, sprinkling width: ≥14m, maximum range: ≥28m; can be adjusted into a column, range ≥28m; can also be adjusted into a fog, range ≥15m.
1. Water absorption
(1) The spray truck should be as close as possible to the operating point and parked.
(2) Open the side door of the walking platform box, take out the water-absorbing hose, and make it swing backward without bending.
(3). Pump the water-absorbing hose into the water as deep as possible to ensure that the pipe end is always less than 300mm from the liquid surface during the operation.
(4). Push the four-way valve handle 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 take power, and the pump starts to run.
(6) The operator can pass the sight glass on the upper part of the rear head. When the liquid level reaches the middle of the sight glass, the driver should be notified. Colleagues should quickly pull the suction hose away from the water surface or close the four-way valve.
(7) After retracting the hose, put it back in the box and close the side door.
(8) Drive the sprayer away from the pumping location.
2. Spraying operation
(1) Pull the rear handle of the four-way valve parallel to the ground, open the ball valve you want to spray (forward, rear, side, and shower), then start the engine, hang the transmission into gear, and take the power take-off When the switch is pulled back, the gear is shifted to take power, then the clutch is disengaged, the pump starts to run, and watering
(2) After the water in the tank has been sprinkled, the driver should promptly push the power take-off handle forward to disengage the gear, and the sprinkler pump stops running.
