As we know, Dongfeng Greening and Spraying Vehicles are used to prevent and control urban street trees, plant diseases and pests of garden plants, and garden irrigation, and can also be used as vehicles for various functions such as road washing, air dust removal, and detoxification. Sprayer operation need to pay attention to those matters?

1. Sprayer car requirements for water

The general sprinkler work is to use the water of the ditch and pond as a water source. At this time, we need to pay attention to the fact that the end of the suction pipe cannot be completely submerged in water. So as not to inhale the bottom of the pool of stones or silt, and other debris, although the suction pipe end is generally equipped with a filter device, absorbent can not be removed when the filter device. If the water source is shallow, it is necessary to dig some of the water absorption points first, so that some sundries and air enter the suction pipe and affect normal operation. Different sprinklers have different pump configurations. They also have different requirements for the water source they carry. Clean water pumps require less impurities in the higher waters, and turbid water pumps require relatively low water but no stones in the water. And excessive silt, otherwise it will cause congestion.

2. Add water diversion

Just like old-fashioned wells in the past, sometimes because of lack of gravity, they need to use water. For example, a centrifugal pump must add a certain amount of water to the pump before each water absorption. After the water is added, the water must be turned off. Otherwise, the water will be shut off. Quickly reset automatically. Self-priming pumps need to add proper amount of water when they are used for the first time. Afterwards, it is unnecessary to add water.

3. The inlet pipe must be vacuumed

The water inlet system must have a certain degree of vacuum before it can suck water into the tank. The inlet pipe system must be sealed reliably, the hose must be intact, and the hard pipe must not be cracked or damaged. Otherwise, there will be a leakage phenomenon, which will result in a situation where the water cannot be sucked.

4. Parking stalls

Whether the sprinkler is before or after watering, the power take-off device must be parked.

5. Winter water release

In cold winter weather, the water in the pumps and pipes should be vented in advance to prevent the water in the pipes from freezing and freezing. For example, in northern China, winter is generally not used because it is very easy to freeze water. 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 eliminate the debris accumulated in the tank until the water becomes clear.

There are also some need to pay attention to when the sprayer is decommissioned for a long time, the fuel and water should be drained, the machine should be parked in a place where ventilation, moisture, sun protection and fire protection facilities, to avoid exposure.
