Functional description and the principle of Water Sprinkler Truck

The Water Sprinkler Truck has the functions of water spraying, dirt pressure, high and low spraying, chemical spraying, safety rail flushing, etc. It additionally has functions like water transportation, drainage, and emergency hearth fighting. What's the practical description and dealing principle of the Water Sprinkler Truck?

Function Description

Water absorption work

(1) The Water Sprinkler Truck ought to be as shut as potential to the operation purpose and set.

(2) Open the outside door of the pallet box, get rid of the water suction hose, and swing it back while not bending.

(3) Pump the water suction hose into the water as deep as the potential to confirm that the Water Sprinkling Truck pipe finish is often below 300mm from the liquid surface throughout the operation.

(4) Push the handle of the four-way valve to be perpendicular to the bottom.

(5) Place the Water Sprinkler Truck transmission into neutral, then begin the engine, disengage the clutch, pull the facility take-off switchback, and so place the facility geared to require off the facility, and therefore the pump starts to run.

(6) The operator of the Water Sprinkling Truck will pass the observation mirror on the higher part of the rear head. Once the liquid level reaches the center of the observation mirror, the motive force ought to be notified, and therefore the colleague ought to quickly pull the water suction hose aloof from the water surface or shut the four-way valve.

(7) When away from the hose, place it back within the pallet box and shut the outside door.

(8) Drive the Water Spraying Truck aloof from the pumping website.

Spraying operation

(1) Pull the rear handle of the water cart four-way valve parallel to the bottom, open the valve you would like to spray (front flush, rear spray, side spray, shower), then begin the Water Sprinkling Truck engine and place the transmission into gear, pull the facility take-off switch back to induce the facility geared, then disengage the clutch, the pump starts to run and starts to sprinkle water

(2) When the water within the tank is sprayed, the motive force of the Water Spraying Truck ought to push the facility take-off to handle forward in time to disengage, and therefore the mechanical device pump can stop running.

Working principle

The Water Sprinkler Truck uses the engine power of the vehicle to drive the aboard mechanical device pump through the facility take-off, adding water to the vehicle from the water or transporting the water within the tank to every mechanical device through pipes, thereby realizing varied functions.

Before the mechanical device pump works, the liquid stock within the pump should be beyond the pump shaft, that the water of the Water Sprinkling Truck pump should be connected with an associate upward bent elbow and so a horizontal pipe and a fast connexion. The centerline of the short connexion should be beyond the middle of the pump shaft. Line three hundred mm; the water piping system should guarantee no air leakage; the suction head of the suction pipe should be submerged in water to forestall air from being sucked into the water pipe; once connecting the outlet pipe of the water cart to the pump outlet, the length of the straight pipe should be two hundred millimeters before connecting bend.

The mechanical device pump adopts an associate external mix sort self-priming structure, associated there ought to be an acceptable quantity of liquid within the pump. Thanks to the distinction in relative density of the gas and liquid, the gas is separated from the liquid and discharged from the outlet pipe, and therefore the liquid sinks within the gas-liquid separation chamber. When several cycles, the gas within the suction pipe is discharged and full of liquid, and therefore the self-priming method is completed the Water Sprinkling Truck pump begins traditional infusion.

The mechanical device pump will play the functions of water absorption and controlled emptying. The self-priming pump will directly suck the water within the pool into the tank, or directly connect the water injection from the fireplace hydrant within the town street, and suck it into the tank for sprinkling.
