In addition, the following operating details need to be noted during the use of the sprinkler: 1. Requirements for Water Sources by Sprinklers When using sprinklers (Dongfeng or Liberation) as a source of water in a ditch or pond, pay attention to that all the ends of the suction pipe are submerged in 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. Sweater Sweaters are knitted by machine or by hand. The history of sweater knitting is very long. Human beings used leaves and animal skins to cover their bodies in primitive life, and later learned to use knitting techniques, so sweaters were produced. With the evolution of civilization and the invention of technology, there are more and more types of sweaters, with better and better quality. The function of sweaters is generally to keep warm, but with the progress of mankind, people began to pursue the beauty of sweaters.

Sprinklers mainly have the functions of cooling and cooling, road dust, and air purification. The multifunctional sprinkler also has other functions such as fire fighting, pesticide spraying, and high-altitude operations.
Today, we take the sanitation green sprinkler as an example to analyze the size of the sprinkler.
The size of the sprinkler sprinkler does not have a standard parameter, but it depends on the actual condition of the sprinkled floor and the weather. When the road surface is extremely dry, the amount of watering should be relatively increased. When the rain is fine and some road sections are still wet, the amount of watering should be relatively reduced. If there is too much dirt or sand on the road surface, it needs to be cleaned by the sanitation sweeper or after the workers have finished cleaning.
Many users who purchased a sprinkler for the first time always think that the larger the sprinkler is, the better the watering is. This is not correct. The greater the sprinkling volume of the sprinkler, the shorter the road surface distance from the sprinkling water will be, resulting in an increase in the number of watering of the sprinkler tanks and an increase in the relative fuel consumption of the round-trip car, which will reduce the economic benefits.
Secondly, if the amount of water is too large, water in low-lying sections will be easily generated, and some of the water will flow down the road into the sewers. This will result in double waste of water resources and economy. When there is too much soil on the ground, muddy conditions will be easily formed, resulting in even more The secondary pollution of many grounds may even seriously block the sewer. After the ground is dry, it is easier to form a large area of ​​dust and pollution, causing inconvenience to the sweepers of sanitation.
In view of the above, the sprinkling of water by the sprinkler is not good, and the small amount of sprinkling does not have a significant effect. Therefore, it is necessary to formulate scientific and reasonable technical indicators in combination with the actual conditions in the local area in order to obtain practical and economical sprinkler traffic.
2. Sprinklers and water pumping Centrifugal pumps must add a certain amount of water to the water pump before each water absorption. 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 of the sprinkler must be vacuumed. The inlet pipe 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.
4. Sprinklers Parking Sprinklers Whether it is before or after watering, the power take-off device must be parked.
5. Sprinkler Truck Winter Drainage Before the advent of winter, sprinklers should empty the water in the pumps and pipes 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.
6. Sprinkler Precautions The front sprayer of the sprinkler is located at a low position and close to the ground. The spray pressure is greater and can be used for flushing the road surface. The rear nozzle is located at a higher position (the sprinkler head is generally installed on the left and right sides respectively), and the sprinkler surface is wide. When spraying water on highway construction, the front nozzle should be closed when the rear nozzle is used, and the width of the water can be adjusted as needed when using the adjustable nozzle. The wider the sprinkler width, the less the amount of intermediate overlap and the more uniform the sprinkler density.
7. Sprinkler Car Lubrication and Fastening The sprinkler should regularly lubricate the lubrication points of the drive assembly during use, and often tighten the joints to ensure normal use.
8. Sprinklers regularly discharge sewage The storage tank of the sprinkler is provided with a drain 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.
