Light large-flow low-level draining pump

Abstract

The invention relates to the field of water pumps, and particularly relates to a light large-flow low-level draining pump. The light large-flow low-level draining pump comprises a pump case, a motor,a water pump end cover, an adjustable suction inlet and a filter screen type water pump base, the adjustable suction inlet is installed on the end of the water pump end cover, a flange is arranged onthe outer wall of the suction inlet, a plurality of flange through holes are formed in the flange, a plurality of end cover blind holes are formed in the water pump end cover, the water pump end coveris connected with the adjustable suction inlet by virtue of an adjusting bolt, an upper adjusting nut and a lower adjusting nut are respectively arranged on the adjusting bolt on the upper and lowersides of the flange, the filter screen type water pump base comprises a bottom plate and a side wall, the bottom plate is a plane, a plurality of draining holes are formed in the bottom plate, the side wall is of a filter screen type structure, a plurality of inward concave ways are formed in the side wall, and the base is fixedly connected with the water pump end cover by virtue of fastening bolts at the inward concave ways. The light large-flow low-level draining pump has the advantages of the simple structure, convenience in operation and time and labor saving, a water pump is prevented from being damaged, and the flow lift of the water pump is prevented from being reduced.

Description

technical field [0001] The invention relates to the field of water pumps, in particular to a light-duty, large-flow, low-liquid-level suction and discharge pump. Background technique [0002] Water pumps are used for agricultural irrigation or to remove road water. Commonly used drainage pumps have a fixed connection between the pump end cover and the suction port. When the water pump is used to remove road water, the pump needs to be fixed. It is time-consuming and labor-intensive, and it will undoubtedly have a great impact on road emergency operations, and when the water pump works for a period of time, the suction The inner wall of the inlet or the impeller will be worn to a certain extent, resulting in an increase in the gap between the suction inlet and the impeller, thereby affecting the flow rate and head of the pump. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a light-duty large-flow low-liquid-leve...
