The invention relates to a portable diving diagonal flow pump which can have multiple configurations. According to one configuration, a low velocity permanent magnet synchronous motor and a special permanent magnet synchronous motor frequency conversion controller are arranged; according to another configuration, an asynchronous motor is arranged, a common frequency conversion controller can be used in a matched manner for startup, and direct starting can be achieved; an efficient integrated diving diagonal flow type guide vane set is adopted in an internal structure, and a special efficient diagonal flow type impeller is used in a matched manner; an efficient integrated internal water passing outer barrel is adopted on the exterior, a built-in design mechanism is adopted in a pump motor part, and the outer barrel, a motor shell, the guide vane set, the impeller, a front cover oil chamber bearing body, an outlet connector and a base are all made of stainless steel materials; and the performance of being compact in structure, high in efficiency, small in size, extremely light, convenient to move and the like are achieved. In addition, a quick joint water outlet manner is adopted in a single pump, and application is convenient; and multiple pumps can be subject to quick joint to be used in series, and the functions of the large flow and high lift are achieved.
Description
technical field [0001] The invention relates to the technical field of electromechanical integrated mobile pump station equipment, in particular to a portable submersible diagonal flow pump. Background technique [0002] The structure and performance of the diagonal flow pump are between the axial flow pump and the centrifugal pump. It is an ideal pump type that absorbs the advantages of the centrifugal pump and the axial flow pump and compensates for the shortcomings of both. However, most common diagonal flow pumps are long-axis type, which have the disadvantages of heavy weight, large volume, low efficiency, and difficulty in moving; when the water depth is not enough to submerge the motor, it will affect the normal operation of the submersible, making the diagonal flow pump The high requirements of working conditions limit its scope of application. Therefore, developing a portable submersible diagonal flow pump with light weight, small volume, large flow rate, high effi...
