Large-flow portable hydraulic diagonal flow pump

Abstract

The invention belongs to the field of fluid machines and particularly relates to a large-flow portable hydraulic diagonal flow pump. The diagonal flow pump comprises an axial plunger motor, a water pump guide vane body, a water pump impeller, an impeller room and water inlet horn opening, and a motor oil supply and oil return pipe. The axial plunger motor is arranged in the water pump guide vane body. The water pump guide vane body serves as a shell of the axial plunger motor. The axial plunger motor comprises an output shaft and a motor oil inlet and outlet pipe end cover. The motor oil inlet and outlet pipe end cover is connected with the motor oil supply and oil return pipe. The other end of the motor oil supply and oil return pipe extends out of the water pump guide vane body to be connected with an external power unit. The water pump impeller is arranged at the end portion of the output shaft, and the water pump impeller is arranged in the impeller room and water inlet horn opening. The guide vane body and the axial plunger pump are integrally designed, the size of a center area of the guide vane body is reduced, an important role is achieved in optimizing a runner, and therefore the overall size is reduced, the overall weight is reduced, and portability is improved while flow is ensured.

Description

technical field [0001] The invention belongs to the field of fluid machinery, and in particular relates to a large-flow portable hydraulic diagonal flow pump. Background technique [0002] The existing submersible oblique (axial) current pump is driven by a submersible motor, the volume and weight of the motor are relatively large, and the pump body is long, which is not convenient for equipment handling and pumping site work, and the operation is extremely inconvenient; Portable) submersible oblique (axial) current pump, because the motor accounts for nearly 50% of the total weight of the pump equipment, the weight and volume of the pump are limited by the maximum manpower that can be moved. [0003] The existing portable submersible oblique (axial) flow pump reduces the overall weight from two aspects. On the one hand, it is convenient to use a water pump with a small flow rate; on the other hand, it uses light materials such as cast aluminum alloy. However, these two me...
