Sprinkler sprinkler function description:

The sprinkler is equipped with a duck-shaped nozzle or a round-headed punching nozzle, a cylindrical open-spray nozzle or a showerhead nozzle at the back, and a working platform at the rear, equipped with a water cannon. Eight nozzles (optional) can be installed at the rear.

The water sprayer is generally used for flushing the street and plays a role of dust removal and cooling. The water sprayer can change the spraying direction and angle of the water sprayer by adjusting the nozzle thread. The water spray gun can be used for urban and rural landscape greening and emergency firefighting. Lian Peng mouth can be poured down the middle of the road to the dust from the sprinkler, play a role in cleaning the air.

Scrubber chassis cleaning: The chassis closest to the ground must have been muddled by mud. Therefore, before carrying out cleaning of other components, we must first carry out a thorough cleaning of the chassis of the 10-ton sprinkler. After the muddy road, the front and rear hub plates of the 10-ton sprinkler will be stained with yellow mud and small sandstone. When cleaning, it is necessary to use a high-pressure water gun to put it under the hub plate. The direction of the water jet of the high-pressure water jet is toward the direction of the hub plate, so that it can be effectively removed from the hub plate.

Sprinkler cleaning: After cleaning the chassis, we can clean the 10-ton sprinkler body. First, the surface of the paint is washed from top to bottom with tap water in order to wash away the larger volume of sand on the body. Use a towel to gently wipe from the top of the car to the bottom of the car. Please note that the closer the paint to the chassis is, the more carefully it should be wiped to avoid scratching the car paint.

In front of the sprinkler, there is a duck-billed or conical nozzle, followed by a cylindrical sprinkler nozzle or a shower head nozzle, and a working platform at the rear, equipped with a water cannon. There are 8 nozzles on the back.

Sprinkler, green spray vehicle special features: Green sanitation function, suitable for urban sanitation and environmental sanitation, the use of quality leading high-power dedicated sprinkler pumps. After the rush (spray), sprinkle, with side spray (shower), with the back of the platform, install green sprinkler on the platform (cannon with heavy rain, moderate rain, drizzle, fog can be adjusted), with suction pipe, with fire Joints, with self-flow valve, self-priming self-discharge, optional 20 meters green spray reel, high-altitude operations, truck crane cargo and other functions.

Operating system: The engine is mainly driven by the engine. The PTO installed on the gearbox drives the sprinkler pump. The sprinkler pump generates power to spray the liquid inside the tank through the pipe network. Working range: Self-priming height: ≤7m, Sprinkling width: ≥14m, Maximum range: ≥28m; Adjustable into a column with a range of ≥28m; It can also be adjusted to a mist with a range of ≥15m.

(1) The sprinkler should be as close as possible to the operating point and parked.

(2) Open the side door of the walk-in box and take out the water-absorbing rubber hose so that it swings back without bending.

(3). Pull the water suction hose into the water as deep as possible to ensure that the end of the pipe is 300mm below the liquid level during the operation.

(4). Push the four-way valve handle vertically to the ground.

(5). Hitch the transmission to neutral, then start the engine, separate the clutch, pull the power take-off switch backwards to pull the file, and the pump starts to run.

(6) The operator can observe the upper part of the rear head. When the liquid level reaches the middle of the sight glass, the operator should be notified that the coworker should quickly pull the suction hose away from the water or close the four-way valve.

(7) After retracting the hose, return it to the walk-in box and close the side door.

(8) Driving the water truck away from the pumping location

(1) Pull the rear handle of the four-way valve to parallel with the ground, open the ball valve you want to spray (front punch, rear spray, side spray, shower), then start the engine and put the transmission into the gear, take the power take off device. The switch pulls back and pulls the gear, then the clutch is disengaged and the pump starts to run.

(2) After the water in the tank has been sprinkled, the driver should push the power take-off handle forward to remove the gear, and the sprinkling pump stops running.

1. Power take-off device 2, water pump 3, water tank 4, communication valve 5, fire ball valve 6, filter net 7, front flush valve

8. Sprinkler valve 9, side spray valve 10, rear spray valve 11, water spray gun 12, tank cap 13, front punch

14, side spray lotus head 15, after the sprinkler 16, anti-rotation plate ABC, three-way four valve

First, add water

1. Open the car to a predetermined position so that the mouth of the tank is aligned with the tap of the tap. Open the cap and tap water to add water.

2. When the water is collected in the field, water can supply water to the tank through the water pump. Its operating procedure is: connecting a rubber hose to the surface water source at the four-position three-way valve A to make the three-way ball valve A and C communicate, closing the ball valve 7, 8, 9, 10, opening 4, and stepping on the clutch to open the power. Switch, slowly release the clutch (do not be too fast, otherwise it will damage the power take off or gearbox), so that the water pump starts working, you can add water to the tank, stop the switch back to work.

Second, sprinkle water

Connect the c and b of the three-way and four-position valve, close the valve 4, open 7, 8, 9, 10 as needed, where 7 is the forward punch switch for flushing the road and 8 is the water gun switch (can be used for emergency fire fighting. Long-distance watering of flowers and trees). 9 is a side spray switch, which can water the roadside flowers and plants. 10 is a post-sprinkler switch for watering the pavement.

After the water in the water tank is sprinkled, separate the clutch and remove the power take-off device.

Third, watering flowers, emergency fire

Turn on the three-way and four-position ball valves, B and C are connected, 4, 7, 8, 9 and 10 are closed, and then a hose is connected at 5, and the other end of the hose is connected to a water gun. Using the gravity of the water, the water can be flowed freely. . Can also be hung on the power take-off pressure emergency fire or long-distance watering flowers and trees.

IV. Active pump station

Turn on the three-way four-valve A and C. Connect the suction hose to the A port, close the 4, 7, 8, 9, and 10, open the valve 5, and take out the water pipe at port 5 so that the water pump can start working. The pumping of the ground to the second floor serves as an active pumping station.

1. When the sprinkler uses the river ditch or pond as a water source, be careful that all the ends of the suction pipe are not in the water. 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. The water pump requirements for different sprinklers are different. The clean water pump requires no impurities in the water. The turbid water pump requires no stones and excessive sediment in the water.

2. Each time the centrifugal pump absorbs water, a certain amount of water must be added to the pump. After the addition, the water inlet must be closed. When the self-priming pump is used for the first time, it is necessary to add water, and it is unnecessary to add water afterwards.

3. The water inlet pipe system must maintain a certain degree of vacuum before it can suck water into the tank. The inlet pipe system must be sealed reliably, the hose can not be damaged, the hard pipe can not have cracks, otherwise it will have a phenomenon of air leakage, which will result in the situation that it cannot suck water.

4. When the sprinklers are in front of the water or before the water is sprayed, the power take-off device must be parked.

5. Before the advent of winter, the water in the pumps and pipes should be vented to prevent freezing. In northern China, which is generally no longer under construction during the harsh winter season, the water in the pumps and pipes will be drained immediately after construction is completed to prevent future problems.

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

7. Lubricate the lubrication points of the transmission assembly on a regular basis during use, and frequently tighten the coupling points to ensure normal use.

8. The sprinkling tank storage tank is provided with a discharge pipe. The inlet of the pipe is the lowest point of the 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.

Before the sprinkler works, the liquid in the pump must be higher than the pump shaft. Therefore, an upwardly bent elbow should be connected to the pump inlet, and then a horizontal pipe and quick connector must be connected. The center line of the quick connector must be 300 mm higher than the centerline of the pump shaft. Import pipeline system must ensure that no air leakage; suction pipe suction head must be immersed in water, so as not to suck air into the water pipe; outlet pipe and pump outlet connection must ensure that the length of straight pipe ≥ 200 mm and then take over the bend.

The sprinkler pump adopts an external mixed self-priming structure, and an appropriate amount of liquid should be stored in the pump. After the pump is started, the impeller rotates and a negative pressure is formed at the inlet of the impeller. The gas in the suction pipeline is mixed with the liquid in the pump and passes through the pressure chamber to enter the gas-liquid separation chamber. Because of the difference in the specific gravity of the gas and liquid, the gas is separated from the liquid and discharged from the outlet pipe. The liquid sinks in the gas-liquid separation chamber and is circulated repeatedly until the gas in the suction pipe is drained and filled with liquid to complete the self-priming process. The pump started normal infusion.

The sprinkler pump can function as a suction and pressurization drainer. The self-priming pump can directly inhale the water from the pond into the tank, and can also directly connect the water from the fire hydrant in the city streets and inhale the water in the tank.

(1) Maintenance of automobile chassis and supporting pump shall be carried out according to the corresponding instructions for use.

(2) Before use, the vehicle should be worn out according to the requirements of the vehicle's instructions.

(3) When the long-distance transfer is consigned, there should be a fixed anti-skid device around the vehicle, and there should be more than 200mm clearance around the vehicle. If the self-conversion is performed, the front nozzle and rear sprinkler should be removed to prevent loosening.

(4) Check regularly whether there is any clogging in the holes and mouths, and clean up the debris when it is found to be clogged.

(5) After each shift is completed, the oil should be cleaned, the pipelines must be neatly arranged, and the scene should be cleaned up.

(6) If the vehicle is not used for a long time or stored in winter, the remaining water in the tank, the pump and the pipeline shall be drained, and it shall be parked in the carport during storage and wipe clean to avoid exposure to rain and rain.

First, the motor part

1. No response after power on. Most of them are caused by short-circuiting of power plugs, power outlets, and motor windings.

2, difficult to start or can not start, and accompanied by "squeak" sound. During inspection and repair, small bamboo strips can be used to rapidly move the blades according to the running direction. If the motor is quickly operated, it indicates that the starting capacitor or starting winding is damaged. Replace the capacitor with the same capacity or repair the starting winding. If the motor is issued, the motor and the pump head are mostly. Mechanical failure, such as bearing damage, stuck impeller and so on.

3, the motor can run, but the speed is slow, and the chassis is overheated, burned odor. Most of them are caused by the short circuit of the motor windings. The motor should be disassembled and repaired by welding, jumper, isolation, rewinding, etc., depending on the damage.

4, large noise and vibration during operation. Most of the bearings are damaged or the bearing and the chassis are not properly mated. The motor must be dismantled for inspection. If the bearings are damaged, they should be replaced. If the bearings run out of the circle, the pump shell can be mated with the stencil treatment. If the bearings run in a circle, The wear part of the motor shaft is stenciled, and the wear is serious. The repair is performed by first surfacing after welding.

Second, sprinkler pump head section

1. The motor runs normally but has little or no water. This situation should first check the sprinkler pump seal, check should first unplug the power plug, hand plug the suction port, fill the water pump, with the mouth to seal the exit and blow in the air, observe the pump head is leaking The leaking point is where the seal is damaged. Common faults include suction pad, outlet pad, and impeller cover pad, which should be replaced during maintenance. If there is no full water phenomenon, the impeller is damaged, the water-retaining partition between the water-absorbing chamber and the outlet chamber is worn out, the pump head is covered with water, and the gap between the impeller and the pump casing is increased. The impeller and the pump casing should be replaced. . When replacing the rake wheel, care should be taken to completely remove the remaining copper blades in the pump so as not to damage the new impeller again.

2, the chassis is charged. Most of them are damaged by water seals. Water penetrates into the motor through the motor shaft and deteriorates the insulation performance of the motor. It can be repaired by replacing the water seal and drying the motor. It should be noted that because the water pump is exposed to water for a long time and it is open to work in the open air, it is prone to moisture and deteriorates the insulation performance. In order to ensure personal safety, the self-priming pump of the electric sprinkler should be reliably grounded.

Sprinklers are exempted from the announcement that they will be exempted from the use of sprinklers. Customers who purchase this vehicle may be exempt from vehicle purchase tax. Exemption from exemption from purchase of additional tax

Sprinklers are exempt from vehicle purchase tax quotas: The purchase price of special invoices for motor vehicle sales includes value-added tax. Therefore, when assessing vehicle purchase tax, 17% of value-added tax must be eliminated, ie, the purchase of sprinkler vehicles. Taxes and taxation price = invoiced price is 1.17, and then the vehicle purchase tax is levied at a tax rate of 10%. Consumers purchase a 100,000 yuan sprinkler and pay 10% tax after removing the VAT portion. The formula is 100000÷1.17×0.1=8547 yuan.

Sprinkler vehicle purchase tax exemption operation procedure: To the purchase tax payment hall, the staff will provide a tax exemption card for this vehicle according to the exemption announcement, hold the tax exemption card to the local vehicle management office, and the vehicle management office will handle the relevant ownership of the vehicle. .

The most common use of spray trucks is road cleaning. In large gardens, we can also see the spray trucks. A spray truck is a type of sprinkler. It is mainly used for drug spraying on green belts and large gardens on both sides of the road.

This year's winter snow in Beijing is raging. As the weather turns colder every day, the low temperatures and rain and snow will make the car go through a severe test. Here, you may wish to learn some practical first-aid tricks. When the car suddenly meets the snowstorm, you might come in handy.

Cold Syndrome 1: The door cannot be opened

Description of the illness: The snow seeps into the cracks in the car. Under the effect of low temperature at night, the car door key hole or door is frozen, the key cannot be inserted, or it is inserted but it cannot be moved; exhausted the whole body strength, the door Can't open it either.

Wrong way: Use hard to twist the key or open the door.

Symptomatic medicine: If you force the key or hit the car door may be counterproductive, the key may be damaged. If you beat the door, the paint will be damaged. It is recommended that a bottle of warm water (hot water may burst the glass) be poured from home into the icing area. If you have a lighter on your hand, you can burn it at a distance from the door. The most basic method can be used to warm up, of course, the time will be longer.

Prevention tricks: You can inject a little lubricating oil into the door lock hole in advance, and apply a thin layer of grease on the sealing strip around the door.

Chilling II: Window Covered with Snow

Description of the illness: Heavy snow covered the front window so that it completely blocked the sight of the vehicle.

Wrong way: Start the wiper to remove snow.

Symptomatic medicine: As the name implies, the wiper wipes the rain. If the snow covered by the window is thick and even ice has been formed, using a wiper will cause serious damage to its rubber strips and other plastic parts. It is recommended that the car be equipped with a special glass snow shovel or a hard plastic blade to remove ice and snow. Avoid scratching the glass when removing snow and ice. It should be moved in the same direction. Do not scratch back and forth. If the snow is thin, you can enter the car, adjust the air conditioning warm air gear, and set it into a front wind mode. After a few minutes, the snow and ice can evaporate. In addition, some high-end cars are equipped with a rearview mirror heating function, which will solve the problem of rearview mirror icing soon after opening.

Prevention tricks: If you can only park your car outdoors, you should choose a sunny, dry place. When the vehicle is parked with its front facing away from the wind, it can reduce the amount of snow covered by the car body. If necessary, stop at night to support the wiper blade to ensure it will not be frozen.

Usually a sprinkler consists of the following components: special vehicle chassis, tanks, piping systems, and operating systems. Here are the four

A brief description of the parts.

First, special vehicle chassis: generally use Dongfeng, Jiefang, Jianghuai and other types of chassis. At present, the more widely used is the "East Wind"

Cassidy Sprinkler, Dongfeng Doolika Sprinkler, Dongfeng Sanpingcha Water Sprinkler, Dongfeng 140 Sprinkler (Long Head), Dongfeng 145

Sprinkler (flat head), Dongfeng 153 sprinkler (flat head), Dongfeng 1208 sprinkler (rear double bridge).

Second, the tank production: Chu Sheng company uses automatic assembly line tank production process is divided into: cutting, automatic welding puzzle, head spinning into

Type, tank rolling and other domestic advanced production technology. Tank materials are mostly made of high-quality carbon steel plates. Special use case

Under the customer's needs can also be imported South Korea 304 stainless steel. Tank volume is 4 cubic, 5 cubic, 6 cubic, 8 cubic

10 cubic meters, 13 cubic meters, and 15 cubic meters.

Third, the pipeline system consists of "pipes, valves, filter devices, outlets (before punching, side spray; high side shower; after work

Platform with green sprinkler.

Fourth, the operating system: mainly driven by the engine gearbox, gearbox installed on the PTO driven sprinkler pump, sprinkler produced

Power to spray the liquid inside the tank through the pipe network. Work scope: Self-priming height: ≤7m, Sprinkling width: ≥14m, most

Large range: ≥28m; Can be adjusted into a column with a range of ≥28m. It can also be adjusted to a mist with a range of ≥15m.

Optional configuration: Spilling discs, drug pumps, anti-corrosion and anti-corrosion in tanks, multiple inlet and outlet connections, solenoid valves, pneumatic valves, etc.

Into facilities to meet the needs of different users.

Take a sprinkler as an example:

In the conversation with the user, we can ask the user: under what circumstances the car is used? Is it the urban road spraying or the landscaping spray or the road surface dust?

From which we can understand the driving conditions of the car, the user valued the function of which part of the car. If the road surface is flat, then there is no need for too much engine power. If the road is steep, a high-powered engine should be used. If it is a green sprinkler, then we must pay attention to the appropriate nozzle, the performance of the water gun is also relatively more critical.

After that we can ask the user: How much tonnage or volume is needed?

The wheelbase and length of each car are determined so that after the tonnage or volume has been determined, the vehicle type that the user generally needs can be determined. Then combined with the previous questions, we can recommend the user to the appropriate sprinkler.
