Single-pole single-suction submerged pump

Abstract

The invention relates to a single-pole single-suction submerged pump. The submerged pump comprises a pump frame, a fixed nut, an upper bearing, a motor output shaft, a lubricating hole, a lower bearing, a base, an oil seal, a support pipe, a pump cover, an impeller, an impeller nut, a filter screen, a pump body, a lower protective sleeve, a shaft sleeve, a protective sleeve end cover, a liquid outlet pipe and a flange; the pump frame is arranged on the base; the fixed nut, the upper bearing, the motor output shaft and the lubricating hole are arranged in the pump frame; the upper bearing is arranged at the upper part of the motor output shaft, and is fixed through the fixed nut; the lubricating hole is formed in the lower end of the motor output shaft; the liquid outlet pipe is connected into the pump body; an infusion pipe is bent up; and the flange is arranged at the tail end. The submerged pump is simple in structure, stable in work, excellent in sealing property, long in service life and low in production cost, and resists acid and corrosion.

Description

Technical field [0001] The invention relates to a pump body, in particular to a single-pole single-suction submerged pump. Background technique [0002] Existing submersible pumps are restricted by the length of the shaft, and the pump body cannot rise and fall with the liquid level, so it cannot suck the liquid in the deep storage tank and the pool. Generally, it is only suitable for the shallow pool with the liquid depth within 2M. Suction and conveying medium; secondly, because the position is fixed during suction and cannot be moved horizontally, precipitation is prone to occur at the bottom of the pool during the suction process, so it is generally not suitable for conveying liquid with granular medium. Although the extended shaft length can be used to suck the liquid with the deeper liquid level in the deep pool, the extended shaft length not only requires high shafts, the long shafts are difficult to manufacture and transport, the manufacturing cost is high, the precision ...

AI Technical Summary

Problems solved by technology

[0002] The existing submerged pumps are limited by the length of the shaft, and the pump body cannot rise and fall with the liquid level, so they cannot pump liquids in deep storage tanks and pools. Generally, they are only suitable for shallow pools with a liquid depth of less than 2M. Suction conveying medium; secondly, because the position is fixed during suction and the level cannot be moved, sedimentation is prone to occur at the bottom of the pool during the suction process, so it is generally not suitable for conveying liquids with granular media

Although the length of the extended shaft can be used to pump liquids with a deep pool and a high liquid level, the length of the extended shaft not only has high requirements on the shaft, but also the long shaft is difficult to manufacture and transport, the manufacturing cost is high, the precision requirements are also high, and the work is not easy. Stable, poor anti-resonance, easy to shake when working

In addition, the long-axis submerged pump is also large in size, and it is inconvenient to transport and store (need to be placed and transported upright)

Furthermore, the shallow pond occupies a large area, which is not conducive to saving land
