Abstract

The utility model discloses a segmented high-lift multistage submersible sand discharging pump, relating to the field of submersible pumps for mechanical engineering. The segmented high-lift multistage submersible sand discharging pump is mainly used for solving the problems of high-lift submersible sand discharging pumps that impellers are easily worn and the leakage is large. According to the segmented high-lift multistage submersible sand discharging pump, the bottom of a pump body (3) is connected with a base (8) through double-headed studs, a balance hub (10) is mounted at the upper part of an upper impeller (11), a skeleton oil seal (9) is mounted at the lower part of a sealing shell (1), and a middle section (13) is sealed through a sealing ring (6). The segmented high-lift multistage submersible sand discharging pump has the advantages that the dismounting and mounting are facilitated, and the production efficiency is increased; due to the double-tube tapered pump body, the flow loss is reduced, and the unit efficiency is increased; the structure is segmented, the diameter of a rotor shaft is increased, and the radial swing is reduced, so that the impeller is difficultly worn; due to the effective binding face of the balance hub, the pressure is balanced, the leakage is reduced, and the service life of the submersible sand discharging pump is prolonged.

Description

Segmented high-lift multi-stage submersible sand discharging pump
Affiliated technical field
