First of all, it is necessary to do a good job on the requirements of the water source: When the sprinklers use the river ditch or pond as a water source, 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.
Secondly, we must pay attention to the method of adding water: Before the centrifugal water pump absorbs water, a certain amount of water must be added to the water pump. After the water is added, 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.
Again, keep in mind that the water inlet must be vacuumed: the water inlet system must maintain a certain degree of vacuum before it can draw 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.
When using the sprinkler to sprinkle water in specific operations, it is necessary to correctly recognize that: the sprinkler head is located at a lower position and close to the ground, and the spray pressure is relatively large, which can be used for flushing the road surface; the position of the rear spray head is relatively high (the sprinklers are generally installed one after the other. ) Widesprinkling surface can be used for road construction and watering. When using the rear nozzle, the front nozzle should be closed. When using an adjustable nozzle to spray water, 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.
There is also a need for proper parking: When the sprinklers are in front of the water or before the water is sprayed, the power take-off device must be parked.
Special attention should be paid to water discharge in winter: Before the advent of winter, the water in the water pump and water 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.
In addition, the lubrication and fastening of the sprinkler: In the course of use, it is necessary to regularly lubricate the lubrication points of the transmission assembly, and frequently tighten the joints to ensure normal use.
Lastly, sprinklers should be regularly drained. 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.
In order to facilitate the correct use of the sprinkler and to reduce the obstacles caused by improper operation during use, Cheng Li Special Automobiles reminds the drivers that the friends should carefully read the manual before using the sprinkler and strictly follow the operating requirements. .
