洒水车水泵压力太小怎么解决?

一、洒水车管道过滤网梗塞了,由于洒水车水泵抽进去的水不可能全部是洁净的自来水,可能是脏水池或是池塘里抽的水,那样水里杂质太多,过滤网容易被杂物堵住了,如沙石、塑料袋、树枝等杂物,只需求把过滤网三通内的过滤网拆下来清洗洁净,确保畅通,即可恢复正常的工作,过滤网的位置在洒水车水泵进水口管道中端。认真察看抽水过程中各部件的漏水漏气状况,检查抽水四通阀位置能否正确,检查出抽水口或管道。
1. The filter screen of the sprinkler pipe is blocked. Because the water pumped by the sprinkler pump can not be all clean tap water, it may be dirty water or water pumped from the pond. There are too many impurities in the water. The filter screen is easily blocked by impurities, such as sand, stone, plastic bags, branches and so on. It is only necessary to remove the filter screen in the three-way of the filter screen and clean it to ensure smooth flow. The filter screen is located in the middle of the intake pipe of the sprinkler pump. Carefully inspect the water leakage and air leakage of each component in the process of pumping, check whether the position of the four-way valve is correct, and check out the outlet or pipeline.
二、叶轮呈现磨损变形,招致洒水泵叶轮正常旋转但无法正常进出水,只需改换新叶轮即可。
2. The impeller is abrasive and deformed, which causes the impeller of sprinkler pump to rotate normally but not to enter and leave water normally. It is only necessary to replace the new impeller.
三、水泵水封长时间老化后容易呈现缝隙,招致空气进入,招致水泵漏水后压力缺乏,处理办法是认真检查工作中的水泵能否有缝隙泄露水。
3. The seals of water pumps tend to show cracks after aging for a long time, which leads to air entry and pressure shortage after water leakage. The treatment method is to carefully check whether there are cracks in the water pumps in the work.
四、洒水车水泵泵内无水工作,招致水泵内机械密封呈现无水干烧的现象,改换机械密封即可。
4. There is no water in the pump of sprinkler, which causes the phenomenon of dry burning without water in the mechanical seal of the pump. It is enough to replace the mechanical seal.
五、传动轴功率缺乏,使得水泵内叶轮未到达正常工作转速,加大油门即可。
Fifth, the lack of power of the transmission shaft makes the impeller in the pump fail to reach the normal working speed and increase the throttle.

为保证泵具有良好的自吸性能,必需满足以下条件:
In order to ensure that the pump has good self-priming performance, the following conditions must be satisfied:
1、泵工作前,泵内的液体存量必需高于泵轴,因而泵进口处必需接一个向上弯的弯管再接一个程度管和快速接头,快速接头中心线必需高于泵轴中心线300毫米。
1. Before the pump works, the liquid stock in the pump must be higher than that in the pump shaft. Therefore, the inlet of the pump must be connected with an upward bending elbow and a degree pipe and a quick joint. The center line of the quick joint must be 300 mm higher than the center line of the pump shaft.
2、进口管路系统必需保证不漏气,密封性能完好。
2. Import pipeline system must ensure no leakage and good sealing performance.
3、吸水管的吸入头必需浸没于水下,以免空气吸入水管。
3. The suction head of the suction pipe must be submerged in water to avoid air suction pipe.
4、出口管道与泵出口衔接时必需保证直管长度≥200毫米后再接弯管。
4. When connecting the outlet pipe with the outlet of the pump, it is necessary to ensure that the straight pipe length is more than 200 mm before connecting the elbow pipe.
5、进水口管道中端必需有过滤网三通,保证水进入水泵前不会有杂质损坏泵内精细部件。6、叶轮磨损严重。叶轮叶片经长期运用而磨损,也会影响水泵性能。
5. The middle end of the intake pipe must have a three-way filter to ensure that no impurities damage the fine parts of the pump before water enters the pump. 6. Impeller wear is serious. The wear and tear of impeller blade after long-term use will also affect the performance of water pump.
7、抽水管道的密封垫漏水也会影响水泵的抽水吸力。
7. Leakage of sealing pad in pumping pipeline will also affect pumping suction.
