How to operate the water bowser and water spraying truck?

　　1.Brief Introduction of working principle and structure of water tank truck

　　(1)structure drawing

　　water canon Sprinkler Tnak Truck chassis

　　Rear Sprinkler Pump system and pipeline Front Sprinkler

　　2. Chassis

　　Water bowser tank truck adopts second class chassis.

　　3. Tank

　　Structure shown as below drawing, tank shape can be oval or bread, made of carbon steel. The tank is adopted 2~3 compartments, the compartment board has holes underneath, whose function is to reduce the shock of wave to the tank while moving. To proof of corrosion, tank inside is non-toxic and anti-corrosion treated, and tank surface is painted anti-corrosive and decorative paint .

　　4. Manhole

　　The round manhole cover is adopted with breath hole, which keeps the pressure of the tank inside and outside equal when filling in water.

　　5, PTO

　　The PTO of Water Truck series is controlled by switch. When Open the pneumatic switch, the gear of PTO enters into engage position. Through the shaft drive the pump working. When close the pneumatic switch, the pump stops working immediately.

　　6, Pump

　　The structure principle and maintenance are attached.please find attachment “pump instruction manual”

　　7, Ball valve

　　There are usually one piece of four-position tri-link ball valve and six pieces of duel-link ball valve in water truck. The four-position tri-link ball valve is a kind of ball valve which can shape three liquid channels. This ball valve can quickly change the direction of liquid. It is widely used in non-corrosive medium. It is through the position of handle to makes any of two holes open or close.

　　8.Sprinkler

　　The front of the car is equipped with duckbill nozzle or round red mouth, the back is equipped with a cylindrical watering mound, side showers.Rear of car is mounted with antiaircraft gun(Optional).Sprinklers are generally used for washing streets, eliminating the dust and cooling air.the water sprinkler can be adjusted to change Sprinkler spraying direction and angle, antiaircraft gun can be used to effect urban and rural areas and emergency fire engines. Shower nozzle can be poured down Middle of the road washing dust and clean the air.

　　Operation Instructions

　　1.Preparation before using.

　　(1).Check the oil surface of lubrication in transmission, based on bottom edge of oil surface plug hole, adding gear oil when not enough.

　　(2). Check the transmission lever, let it be in neutral position, and check the controlling lever position of PTO,keep it be horizontal and right position, then check the accelerator controller, make it to be minimum.

　　2.Operation for Water Pump and PTO

　　(1).Start, connect the related pipelines well, start the engine,when the vehicle pressure gauge reads at 0.3Mpa, press the clutch pedal, and release the clutch slowly (If too fast, PTO and transmission will be damaged), then put it into gear.Through the oil throttle controller, it can control the working speed of water pump.

　　(2).Stop, boost the oil throttle controller, adjust it to a minimum, press the clutch pedal,and then keep the controlling switch of PTO back to the previous position, make the PTO box out of gears.

　　3.Check after using the water spraying truck

　　(1) Check if returning the controlling switch of PTO, and check if the oil throttle is on the minimum position.

　　(2) Check if the position for valve handle lever is “off” state.

　　4. Instruction for Different Operation of Water Tank Truck

　　1) Refilling Water tanker truck.

　　a. Filling in Running Water: Stop water truck in designated position, open the manhole, insert the water hose into manhole, turn on the water till the tanker is totally full.

　　b. Filling in open water: Using pump to suck water into the tanker. Main process:

　　Connect a water hose in open of "3 Way Valve G", turn the valve into open position horizontally as below diagram (note: 3 Way Valve is close if the handle face same direct with dent mark on the valve), close stainless steel valve A, B, C, D, E, F and Fire Hydrant I，open Aluminum Valve H; go to cabin and press down the clutch, open the PTO switch, gradually release the clutch (Note: don't release too quick, or it will ruin PTO and Gearbox), then pump start to work and fill water into the tanker, close all the open valves.

　　Water Flowing Ways: Entering from 3 Way Valve G, pass the filter & pump, through Aluminum Valve H, finally into the tanker. (Valve A, B, C, D, E, F, G are all closed.)

　　C. Filling with Fire Hydrant Water: Connect the fire hydrant hose in "Fire Hydrant I", close the valve and turn the "3 Way Valve G" to vertical position, then water will flow into the tanker.

　　Water Flowing Ways: Entering from Fire Hydrant I, through Aluminum Valve H, finally into the tanker. (Valve A, B, C, D, E, F, G, H are all closed.)

　　(2) Water Spraying Operation of water bowser

　　To Spray water on the road, the main process: Turn 3 Way Valve G to vertical postion (note: 3 Way Valve is close if the handle face same direct with dent mark on the valve), Close Aluminum Valve H & Fire Hydrant I, open stainless valve A, B, C, D, E;go to cabin and press down the clutch, open the PTO switch, gradually release the clutch (Note: don't release too quick, or it will ruin PTO and Gearbox), then pump start to work and start the spraying water. Open Valve F to water high tree or grass far distance beside the road.

　　Water Flowing Ways: flow out of the tanker, through 3 Way Valve G, water filter & pump, front & back spraying hose. (H & I Valve are closed)

　　(3) Firefighting Operation

　　In any fire emergency, the water truck can use to extinguish fire with water gun at connecting on fire hydrant water. The main operation process: Turn 3 Way Valve G to vertical position (note: 3 Way Valve is close if the handle face same direct with dent mark on the valve), close stainless steel valve A, B, C, D, E and aluminum valve H, open fire hydrant I and stainless steel valve F; go to cabin and press down the clutch, open the PTO switch, gradually release the clutch (Note: don't release too quick, or it will ruin PTO and Gearbox), then pump start to work, water gun and fire hydrant can use to extinguish fire

　　Water Flowing Ways: flow out of the tanker, through 3 Way Valve G, water filter & pump, water gun F & fire hydrant I. (Valve A, B, C, D, E, H are closed)

　　(4) Mobile Pump Station of water spraying truck

　　As the truck have water pump, it can become mobile pump station if needed. Main process: Connect hose in 3 Way Valve G, Turn 3 Way Valve G to vertical position (note: 3 Way Valve is close if the handle face same direct with dent mark on the valve), close stainless steel valve A, B, C, D, E and aluminum valve H, open fire hydrant I and stainless steel valve F; go to cabin and press down the clutch, open the PTO switch, gradually release the clutch (Note: don't release too quick, or it will ruin PTO and Gearbox), then pump start to work as mobile pump station.

　　Water Flowing ways: flow in from 3 ways valve G, through filter & pump, then out in Fire Hydrant I. (Valve A, B, C, D, E, F, G, H are closed)
