This type of trailer pump combines the mobile carrier with the rainproof box that integrates the generator set and the drainage equipment. It becomes a professional use of the drainage and rescue mobile pumping station. The trailer mounted pump is suitable for all-weather field open-air operation, and has overall stable and reliable performance. The integrated operation is light and practical, fast response, high drainage efficiency, convenient combination of functions, wide use and high cost performance. The flood control pump can well meet the needs of outdoor operation and urban flood control, agricultural drought resistance, municipal engineering and emergency drainage.

In the process of using the flood control pump, it is inevitable that the pump will not be sucked up by the pump. The following is the reason for analyzing why the pump can not pump water and the solution:
1. Since the installation process of the pump is not careful enough, for example, the inlet pipe of the flood control pump should be supported by other supporting measures to support the weight of the imported pipe, and some users rely on the weight of the entire imported pipe during installation and use. The mobile pump unit is used to carry, so that when the inlet pipe is installed, it is easy to appear that the joint and the flange are not sealed perfectly, and the atmosphere is sucked into the pipe so that the whole system can not reach the negative pressure state and is always in the exhaust state, and the pump is long after the time. The water temperature inside the body rises and there is a phenomenon that the pump trailer is always unable to pump water. The solution is to re-adjust the installation mode to detect the leak point and repair it.
2. If the commonly used trailer water pump exceeds the specified self-priming height, it will also be the reason why the pump can not pump water, and some users have multiple suction pipe elbows, and the normal installation and use of the flood control pump, The import pipe elbow allows the number of elbows to be between 1 and 2, which may also cause the flood control pump to be pumped.



3. Due to the lack of knowledge about the operation of the trailer mounted pumps, there is no pre-irrigation of water in the pumping chamber of the flood control pumping tank before the use of the pump. Therefore, it is only necessary to prevent the pumping of the pump trailer. Fill the pump with water to absorb the water.
4. Since the suction pipe of the drainage pump is not configured according to the allowable pipe size, but the water pipe is enlarged or changed from one to more than the water pipe, it will cause the flood control pump to suck the water, so consult the professional flood control pump manufacturer before changing the size of the imported pipe or increasing the number of pipes.
5. Since the depth of the water inlet of the pump is not more than 25cm, the air content on the surface of the liquid is large. It is also the reason why the pump can not be sucked up by the pump. The solution is to extend the water pipe to the bottom of the pool. .
6. Due to the urgency of the water flow in the river or the sewer, the phenomenon of sloshing in the inlet pipe of the pumping and smashing pump, this will also cause the pump to not pump water. The solution is to use a baffle around to reduce the water flow phenomenon, or use a vacuum-assisted flood control pump to improve the self-priming performance of the flood control pump.
