Sanitation sprinkler

Sanitation sprinklers are mainly suitable for all kinds of road washing, trees, green belts, lawn greening, construction of roads, factories and mines, and construction of high-rise buildings.

wash. With sprinkler, dust, high and low spray, pesticide spraying, guardrail flushing and other functions. It has been widely used in cities and townships to sprinkle water and sanitation.

Sanitation sprinklers are categorized according to their uses: divided into spray-type, flush-type, spray-wash-type sprinklers;

Sanitation sprinklers are categorized into chassis types: automotive, semi-trailer and trailer-mounted sprinklers;

Sanitation sprinklers are classified by capacity and can be divided into a number of parties or tons of sprinklers.

Sanitation sprinklers classified by brand: sprinklers According to the different chassis can be divided into Dongfeng sprinklers, Jiefang sprinklers, Futian sprinklers, JAC sprinklers, Hualing sprinklers, Shaanxi Auto sprinklers, heavy truck sprinklers, Beiben sprinkler Cars and so on.

Optional configuration: The prices of sprinklers vary from place to place throughout China. Standard configuration sprinkler (greening sprayer, water tanker): front shower, side spray; high side shower; rear working platform with green sprinkler, can be adjusted into a column, with a range of ≥ 28m; can also be adjusted to fog Shape, range ≥15m. Optional medicine tray, fight drugs machine. It can also install advanced facilities such as medicine discs, drug pumps, anti-corrosion and anti-rust in the tank, multi-directional inlet and outlet water connections, solenoid valves, pneumatic valves, etc. to meet the needs of different users.

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.

Starting from September 1, 2010, Guangzhou's Pearl River Delta region will implement the National IV emission standard. At that time, the country's three-emission motor vehicles will not be able to license in the region, and many national first-tier cities will continue to implement the three national emission standards. The three national emission standard engines are divided into three types. One is the high pressure common rail technology, which is often referred to as the EFI engine. The second is the single pump, that is, the oil pump oil supply engine. The third is EGR. A secondary exhaust engine is equipped with a tail gas recycling technology that has reduced vehicle exhaust emissions.

When the sprinkler uses the river ditch or pond as a source of water, pay attention to 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.

Every 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.

The water inlet 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.

Before the water sprinkling vehicle or water sprinkling, the power take-off device must be parked.

Before the advent of winter, the water in the pumps and pipes should be vented to prevent freezing. The northern part of the country is generally no longer under construction during the severe winter. Therefore, after the construction is completed, the water in the pump and the water pipe will be drained immediately to prevent future problems.

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 sprinkler density.

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.

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.

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.

Gasoline prices are comparable to gold, and for car owners, the car's fuel consumption soars. Fuel consumption is the most important factor in the process of car owners' use. How much fuel consumption is related to the owner's car use. If you find that fuel consumption is suddenly over 10% more than usual, it may mean that the car has a problem. You can look for the causes and remedial measures in the following eight areas in a timely manner:

1. If you find that the taxi's current taxiing distance is significantly reduced while you are driving, you should check if the tire pressure meets the air pressure standard. If the tires are inflated, the fuel consumption will increase.

Tip: Adequate gas for tires is available in due course.

2, check the degree of wear of the tire, if the tire is worn out, it will often slip phenomenon, increase fuel consumption.

Tip: Replace new tires if necessary.

3. If you find that the wheels have abnormal noise during driving or starting, you should check the bearing and brake system for failure. If the wheels rotate abnormally, it will affect the speed of the vehicle and increase fuel consumption.

Tip: Repair the bearing and brake system.

4. Clutch slipping can cause the engine's revolutions to be lost. When you suddenly accelerate, you find that the engine tachometer increases quickly, but the increase in speed is very slow. At this time, it can be determined that the clutch is slipping.

Tip: The clutch plate, clutch platen and drive wheel need to be replaced.

5. When your car has traveled two or three hundred thousand kilometers, the cylinder pressure is usually insufficient, and the fuel consumption will obviously increase.

Tip: If this failure really occurs, the engine needs to be overhauled.

6, when the exhaust pipe appears black smoke, fuel consumption increases, you need to check the carburetor.

Tip: If the carburetor is too dirty, it can be sprayed with a cleaning agent directly into the inlet of the carburetor. If black smoke is emitted at this time, the carburetor can only be disassembled and cleaned.

7. If the spark plug is used for too long, there will be an increase in fuel consumption. Because spark plug damage will reduce the ignition energy, the vehicle speed will slow down, leading to a significant increase in gasoline consumption.

Tip: The spark plug should be replaced.

8, when the car's temperature control switch and thermostat damage, there will be increased fuel consumption. Because the temperature control switch and the thermostat damage will cause the water temperature to decrease, the carburetor will not work properly, resulting in poor atomization of the gasoline and a significant increase in fuel consumption.

Tip: Replace the problem part.
