An upright water pump

Abstract

The invention provides an upright water pump, which belongs to the technical field of machinery. The upright water pump includes a motor frame, a pump casing with a water inlet section and a water outlet section, an outer cylinder vertically arranged between the motor frame and the pump casing, and an impeller assembly arranged in the outer cylinder. The impeller assembly includes a water inlet connected to the water inlet. The inlet of the section is connected to the outlet of the outer cylinder, the lower end of the outer cylinder is connected to the water outlet section, the pump casing and the motor frame are provided with convex rings, the two ends of the outer cylinder are respectively inserted into two convex rings, and the outer side wall of the outer cylinder is in close contact with the inner side wall of the convex ring; The upper end sidewall of the outer cylinder is bent inward to form a cylinder with an axial cross-section that is roughly "L" shaped. An annular groove is formed between the ring part 1 and the inner wall of the outer cylinder, an annular rubber body is fixed in the annular groove, the inner and outer side walls of the rubber body are respectively abutted against the outer wall of the ring part 1 and the inner wall of the outer cylinder; And the axis of the outlet is perpendicular to the axis of the first ring portion. The present invention is structurally stable.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a water pump, in particular to a water pump for upright use. Background technique [0002] Pumps used upright generally include a pump casing, a motor frame, an impeller guide vane assembly, an outer cylinder and a shaft. The pump casing is provided with a water inlet section, a water outlet section and a water passage connecting the water inlet section and the water outlet section; the motor frame is above the pump casing, and the pump casing and the motor frame are fixedly connected by bolts; the outer cylinder is vertically positioned on the Between the motor frame and the pump casing, and the lower end of the outer cylinder communicates with the outlet; the impeller guide vane assembly is arranged inside the outer cylinder and is driven by the shaft. When in use, the impeller guide vane assembly draws the fluid in the water inlet section upwards into the outer cylinder, and ...
