Water truck

Water sprinkling vehicles are also known as spray trucks, multi-function sprinklers, landscaping sprinklers, water tankers, and water trucks. Mainly used for urban roads, large factories, troops, gardens and other units to clean the road, health, dust, watering, spraying pesticides, etc., but also has water transport, drainage, emergency fire and other functions. The types of water sprinkling trucks include Dongfeng Sprinklers, Liberation Sprinklers, Foton Sprinklers, Nanjun Sprinklers, JAC Sprinklers, Hualing Sprinklers, Shaanxi Steam Sprinklers, Heavy Duty Sprinklers, Beiben Sprinklers, etc.

The water-sprinkling truck is equipped with a front spray (spray) and sprinkled, with a side spray, a working platform behind the tank, and a green sprinkler on the platform. The water spray gun can rotate 360° and can be continuously adjusted into a straight punch, column or fog. Shape, range 15-30 meters, sprinkler width ≧ 14 meters, with security guardrail, equipped with Hangzhou Veyron sprinkler pump or Suizhou sprinkler pump, the pump can be self-priming, installed filter, with fire interface, through the hydrant into the water , With self-flow valve, vehicle optional 20 meters green reel, can spray pesticides, spray metal paint tank.

First, the tank

Sprinkler tank structure, the tank is elliptic cylindrical or square, made of steel plate, the vehicle body tank is 2-3 rooms, the bottom of the middle partition has a through hole, the warehouse partition has anti-wave function. To reduce the impact of liquid in the tank when the car is running. An anti-rotation plate is installed at the water outlet to prevent whirlpools from impacting water pressure when water is sprayed. Appearance painted anti-rust paint and decorative paint.

Second, tank mouth

Tank mouth assembly: The large cover is fastened to the tank door neck plate by bolts, and is connected together by a support pin and a cover plate cover, and the small cover is pressed tightly by turning the handle on the small cover clockwise. After reversing, when the ear plate is disengaged, the small cap can be opened. The large cap has a hole of 30, so that the pressure in the tank is basically the same as the atmospheric pressure during the process of adding water.

Three, power take off

The special power take-off matched with the gearbox of each vehicle type, pneumatic operation or manual operation, the operation switch pulls backwards, the take-off force tooth enters the gearing position, the water pump works through the drive shaft, the switch back to the position, the water pump stops working.

Fourth, the pump

Self-priming impeller pumps are special pumps for sprinklers.

Fifth, the ball valve

The sprinkler is equipped with 7 Φ50mm stainless steel ball valves, and 7, 8, 9 and 10 in the figure are used for regulating watering. Φ50mm aluminum tank ball valve, 4 in the figure to control the pumping or sprinkling, open when pumping, close when watering. Φ65mm fire ball valve, can be connected to the fire belt for emergency use.

Six, water sprayer

In front of the sprinkler there is a duck-billed or round-headed nozzle, followed by a cylindrical sprinkler and a side sprayed shower head. The rear of the car is equipped with an overhead spray gun.

The water sprayer is generally used for flushing the streets and plays a role of dust removal and cooling. The sprayer can change the spraying direction and angle of the water sprayer by adjusting the nozzle thread. The spray gun can be used for urban and rural landscape afforestation and the role of emergency fire trucks. . The puff nozzle can pour the dust from the middle water sprayer to clean the air.

special requirement

According to the different requirements of customers, it can be equipped with sprinkler discs, drug pumps, tanks to do anti-corrosion anti-rust treatment, multi-directional inlet and outlet connections, solenoid valves, pneumatic valves and other advanced facilities.

Water requirements

Although the requirements for water sources are not very high for sprinklers, when the sprinklers use river ditches and ponds as the source of water, it is necessary to pay attention to the fact that the ends of the suction pipes are completely submerged. In order to avoid inhaling stones or more sand and drift debris, the suction pipe end is generally provided with a filtering device, and it is forbidden to remove the filtering device during the water absorption. If the water source is shallow, it is necessary to dig up the water absorption area in advance so as to ensure that it does not contain impurities and air.

Add water diversion

The self-priming water pump only needs to divert water when it is used for the first time, and it is not necessary to add water afterwards. Before the centrifugal water pump absorbs water, a certain amount of water must be added to the water pump. After the water pump is added, the water inlet must be closed.

Inlet pipe must be vacuumed

Water inlet pipe system must maintain a certain degree of vacuum before the water can be sucked into the tank, and the inlet pipe system must be sealed and reliable, the hose can not be damaged, the pipe can not have cracks, otherwise it will have a leakage phenomenon, it will cause suction Not on the water situation.

Winter water

Before the advent of winter, the water in the pumps and pipes should be vented to prevent freezing. In northern China, the winter is generally no longer in construction, so after the construction is completed, the water in the pump and the water pipe will be immediately drained to prevent cracks.

Precautions when spraying

The front sprinkler of the sprinkler is located at a low position, close to the ground, the spray pressure is relatively large, and can be used for flushing the road surface; the position of the rear sprinkler is relatively high (the sprinkler is generally installed on the left and right sides of the sprinkler), and the sprinkler surface is wide, and can be used for highway construction and watering. When the rear nozzle is used, the front nozzle should be closed; when using the adjustable nozzle, the width of the sprinkler can be adjusted as needed. The wider the sprinkler width, the less the amount of intermediate overlap, and the more uniform the density of the sprinkler.

Regular sewage

The water tank of the sprinkler truck is provided with a sewage pipe. The inlet of the pipe is the lowest point of the water tank. After a period of use, the discharge pipe switch should be opened periodically to remove the accumulated debris from the tank until the water becomes clear.

Lubrication and fastening

During the process of use, lubrication points of the transmission assembly should be regularly lubricated, and the joints should be tightened frequently to ensure normal use.
