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.

The green sprinkler uses the vehicle gearbox power taker as the power source. The power is transmitted from the drive shaft to the water pump to run the pump at the rated speed. The liquid is sucked into the tank according to the set function, or the liquid in the tank is pumped through the pump. The pressure is discharged from the tank to complete the special functions of the green sprinkler. Pipe network system diagram As shown in figure one. Its operating principle: 4# ball valve can be equipped with pneumatic devices, 5 #, 6 # before and after the pipeline switch is optional, pneumatic device, the rest of the ball valve are manually controlled. All ball valve handles are opened and closed by a vertical pipe line, and are opened in the same direction as the pipe line. The one end of the four-way three-way ball valve facing the red point is closed.

Tank

There are two types of green sprinkler tank shapes: 1. Elliptical cylindrical 2. Square. Greening the plate of the sprinkler for: high-quality carbon steel, stainless steel. Greening sprinkler tanks are divided into compartments, and through the middle of the partitions, through holes are provided at the upper and lower ends to prevent the impact of the liquid in the tank on the tank. An anti-rotation plate is installed at the exit to prevent the vortex from affecting the water pressure when the green sprinkler is sprinkled with water. The surface of the green sprinkler cans is painted with antirust paint and decorative paint.

Tank mouth

Tank mouth set up: The large cover of the green sprinkler is fastened by bolts on the neck of the tank door, and is connected together by a support pin and a small cover plate. Turning the handle on the small cover clockwise can compact the small cover. After reversing, when the ear plate is disengaged, the small cover can be opened. There is a hole of Φ30 on the large cover so that the pressure in the tank can be kept in line with atmospheric pressure during the process of adding water to prevent the deformation of the tank body.

PTO

Power take-offs are divided into manual power take-offs and pneumatic power take-offs. Commonly used on models with air supply, the air source control handle (single-gear switch) located on the left side of the cab controls the engagement and disengagement of the power take-off: Single The gear switch is pulled out to the engaged state, and the single switch advances to the disengaged state. Manual power take-off is commonly used on models with air supply. The manual power take-off is controlled by the handle, the handle is pulled back, and the power take-off works. The handle reset operation is terminated and the clutch must be depressed when the power take-off is engaged and disengaged.

Pump

Self-priming impeller pumps are petrol pumps for green sprinklers. The structure principle, use and maintenance of the water pump can be seen in the manual of the sprinkler pump.

Adjustable propulsion

The greening sprinkler nozzle is composed of pipe joints and nozzles, which can self-adjust the direction of the nozzle and change the width and the direction of the sprinkler.

Voice device

The voice device is composed of a telecommunication switch and a voice device. When the voice device is used, the switch can be connected to send a musical sound to remind passers-by to pay attention. The voice switch is located on the left side of the cab and is set as a single-speed switch. The music sound of the single-speed switch is extracted, and then the music stops.

Start the engine, wait for the whole machine to reach the starting state, step on the clutch to open the pneumatic switch, the power take-off is sufficient to push the shaft sleeve to make the power take off device and the gearbox in the combined state, pull out the handle about 10 seconds to determine the power take off and shift The box is fully integrated. At this time, the clutch pedal is slowly released. The engine idle speed slowly accelerates the pump to the rated speed, and the pump can work normally. After the work is completed, step on the clutch pedal and push the power take-off control handle for about 10 seconds to release the clutch pedal. The power take-off is separated from the gearbox and the pump finishes working.

Do not pull out the power take-off control handle when the storage pressure is insufficient. Otherwise, the power take-off and gearbox cannot be completely combined, resulting in damage to the gearbox and power take-off. When pulling and advancing the power take-off control handle, wait 10 seconds and release the clutch pedal. This ensures the perfect combination of the power take-off and the gearbox. When using a green sprinkler to spray plants or use artillery to flush the ground, be sure to open the ball valve (front or rear sprinkler) or the green sprinkler piping, pumps, seals, etc. will be damaged due to excessive pressure.

For the first time, the greening sprinkler was tested and the pump was working for the first time. It was necessary to inject 20 KG of clean water into the pump. The method is very simple. Simply connect the ball valve to the suction hose and inject the clean water into the hose. Gradually raise the hose and let the water flow into the pump until it is filled with suitable water. When the pump has been used, there will be no water in the pump. Then switch the valve, a series of movements such as hanging on the car to pay attention. When the sprinklers are siphoning at Hetang or other sources of water, the hose should be placed under 300mm below the liquid surface. Take some measures to prevent sand, weeds, and other small objects from being sucked into the pump. Otherwise, it will cause If the water pump is clogged or the pipeline valve is damaged prematurely, the sprinkler should be careful not to engage the power take-off with the function switch unopened, otherwise damage to the pump shaft, power take-off, gearbox, and piping will result. Push the four-way valve of the sprinkler truck to the vertical position, start the engine by putting the transmission into neutral, and disengage the clutch. Pull the power take-off switch backwards to pull the file and pull the force. Then the pump starts to run. This is the driver should pay attention to observe The rear head sight glass can close the four-way valve and pull out the suction hose when the liquid level reaches the middle of the sight glass. Put the hose back in the pipe.

Dismantling: Change the front tire with a triangle pad to plug the rear wheel, and then start to loosen the wheel nut with the wheel nut socket wrench in the vehicle tool. Use the jack to lift the end of the axle, make the wheel slightly off the ground, remove the wheel nut , And then remove the tire from the rim, pay attention to the action should be light, the vehicle staff to cooperate with the tacit understanding, to avoid being injured by the tire, and to protect the valve, in the process of removal should pay attention to the right wheel of the vehicle nut is threaded, The wheel nut on the left is left-handed and the thread that leaks out of the wheel must be wiped clean. It is best to apply a bit of lubricant. If twins are to lower the axle to its original position, then loosen the inner bolts and nuts, and then push the axle with the top of the daughter wheel so that the wheels are off the ground, remove the inner wheel nuts, and then remove the inner wheel tires.

Installation: First use a boring bar to fit the rim bolt hole of the tire into the bolt. Followed by the road wheel Yi bolt adjustment to the center of the bolt hole, and tighten the tire nut. Then lower the jack to the ground where the tire touches and tighten the tire nut. When tightening the tire nut, there is a certain rule. Twist half circle first, then turn one half, and then rotate half a circle clockwise and then half circle In this method, the tire can be tightened more quickly and easily until the nut is screwed to a fixed torque of 420-500 N·m. In the end, if twins are used, the axles must be lifted up again. The tires are slightly off the ground, and the tires can be installed again in accordance with the above method.

The “Three” Big Tips for Sprinkler Winter Maintenance

1. The space for parking Dongfeng sprinklers in the winter must be ventilated, not too humid, because the damp air is prone to corrosion paint and parts.

2. Sprinklers have to be parked for a long period of time. Attention should be paid to the aging, swelling, or deformation of rubber products such as tires. The longer the stopping time, the more difficult it is to recover the deformed parts. If found, it must be promptly sent to the maintenance point for repair.

3. When the sprinkler stops in the winter, the battery will automatically discharge, so be sure to constantly check the battery's power, and timely recharge.

Greening sprinklers are generally used less frequently, especially in northern areas where heavy snow lasts longer and the sprinkler has no way to operate, so it will stop for a long time. When winter sprinklers are parked, maintenance is very There are exquisite, here to tell you some maintenance methods.

Do you know under what conditions the sprinkler should not be on the road?

People with certain experience in driving a car know that the sprinkler sprinkles water and rains on the ground. However, under the rain, the car can't slip on the road. The sprinkler sprinkles water and spills on the road. A layer of "oil", let you be careful and careful, this layer of "oil" will always bring some danger. Of course, it's not that a sprinkler will have a traffic accident when it comes to sprinkling water, but that it should reduce the danger as much as possible.

Sprinklers are able to “skate” passersby to fall on the road after crossing the road, which has attracted the attention of relevant departments. Public readers also telephoned each other and asked the gardening department of the city when to sprinkle water in the winter. When the weather is cold and it is easy to freeze, water can not be sprinkled so as to avoid accidents or danger to pedestrians and vehicles.

The Urban Planning Bureau of the City Six Districts started from November 15th and unanimously “see the face of God” to adjust the sprinkler operating time. The uniform requirement is that the temperature be below 0°C, and the sprinkler cannot spray water on the road.

(1) Do not spray water below 0°C.

(2) Sprinklers should spray water from 9:30am to 12:00am and from 2pm to 5:30pm in a timely manner to handle the large amount of accumulated water in time.

(3) The machine sweeping time is from 5:30 in the morning to 7:00 in the morning, from 10:30 to 12:00 at noon, and from 3 to 5 in the afternoon. Mainly to clear the road surface, during the cleaning process will be mildly wet road, but will not cause water accumulation.
