Problems solved by technology

[0002] In the various types of positive displacement pumps in the prior art, the pump body is mostly irregular in structure, and the pump feet for fixing are usually processed on the specially designed fixed end surface of the pump body, which limits the installation position of the pump body. Since the position of the liquid inlet and outlet on the pump body is fixed, it is impossible to conveniently rotate the axial direction at any time according to the change of the construction site to adjust the orientation of the pump body inlet and outlet, and the liquid port. Only by installing reversing pipes and other structural forms To realize the direction change of the inlet and outlet, and the liquid port, but the construction site is often difficult to erect redundant pipelines due to space constraints, resulting in greater limitations in the use of the pump

Embodiment Construction

[0020] As shown in Figures 1 to 3, this external circulation type rotary piston pump includes a pump body 2 processed with pump legs 3 and inlet and outlet ports 1 and 4, and is characterized in that more than 3 sets of pump bodies are processed on the pump body 2. The pump legs 3 of each group of pump legs 3 form a plane structure between the outer end surfaces, and the planes formed by each group of pump legs 3 intersect in turn to form a regular polygonal structure, and each group of pump legs 3 is located on each outer surface of the pump body 2 of the same position.

[0021] In order to conveniently rotate along the axial radial position and adjust the installation position of the pump, the planes formed by the outer end faces of each group of pump legs 3 on the pump body 2 intersect in turn to form a square structure. In this way, the position of the inlet and outlet ports 1 and 4 can be adjusted by adjusting the radial installation angle of the pump body 2 under the con...

Abstract

The external circulating drains rotary piston pump in the displacement pump area, comprises the pump body with pump stand bar and liquid inlet and outlet openings, featuring in over three sets of pump stand bars on the pump body with the space between their outside end surface in planar structure, which sequentially crosses to form regular polygon, with each set of pump stand bars located at the same place of each of the outside surface of the pump body. Without changing the original loading space, it can proceed multi-azimuth rotary loading along the axle radially in the angles of 90degree, 180degree, 270degree or 360degree, to adjust the liquid in and out location of the pump for the convenience of load.
