The use of sprinkler skills

 使用Watering cart (East wind or liberation)Read the instruction manual carefully before use。Operation in strict accordance with the requirements of use is an important guarantee for the use of sprinklers。
1.Water requirements。When the sprinkler(East wind or liberation)When using rivers and ponds as water sources, pay attention to the end of the suction pipe all into the water。In order to avoid inhaling stones or more sediment, drift debris, suction pipe end is generally equipped with a filter device, water suction is strictly prohibited to remove the filter device。If the water source is shallow, it is necessary to dig the suction deeper in advance to ensure that it does not contain debris and does not enter air。Different sprinkler pumps have different requirements for water sources, clean water pumps require no impurities in the water, turbidated water pumps require no stones and too much sediment in the water。
2.Additional pilotage。Before the centrifugal pump absorbs water each time, a certain amount of water must be added to the pump, and the water inlet must be closed after the addition。When the self-priming pump is used for the first time, it needs to add water, and then it is unnecessary to add water。

3.The inlet pipe must be vacuumed。The water inlet pipe system must maintain a certain vacuum degree when absorbing water,To get the water into the tank。The water inlet pipe system must be sealed reliably, the hose can not be damaged, and the hard pipe can not be cracked, otherwise there will be air leakage, which will cause no water suction。
4.Stop gear。Whether it is before absorbing water or before sprinkling water, the gear of the force taking device must be carried out when stopping。
5.Winter drainage。Before winter, the water in the pump and water pipe should be emptied to prevent freezing and cracking。In the north of China, there is no longer construction in general winter, so after the construction is completed, the water pump and the water pipe are immediately emptied to prevent future problems。
6.Sprinkling precautions。The sprinkler head position is low, close to the ground, spraying pressure is large, can be used to wash the road;The position of the rear nozzle is higher(The rear sprinkler head is generally installed one on each side)The water surface is wide, can be used for highway construction sprinkler, after the use of the nozzle, the front nozzle should be closed;When using an adjustable sprinkler, the sprinkler width can be adjusted as needed。The wider the sprinkling width, the less overlap in the middle and the more uniform the sprinkling density。

7.Lubrication and fastening。In the process of use, the lubrication points of the transmission assembly should be regularly lubricated, and the joint points should be often tightened to ensure normal use。
8.Periodic blowdown。The sprinkler storage tank is provided with a sewage pipe, and the inlet of the pipe is the low point of the water tank。After a period of use, the sewage pipe switch should be opened regularly to remove the debris accumulated in the tank until the water becomes clear。
