Wear-resistant efficient horizontal centrifugal sand pump and working method thereof

Abstract

The invention discloses a wear-resistant efficient horizontal centrifugal sand pump. The wear-resistant efficient horizontal centrifugal sand pump comprises a pump housing, a motor shaft, an outer magnetic rotor, an isolation sleeve, an inner magnetic rotor, a linkage shaft, an impeller, an end cover and a wear-resistant layer, wherein the motor shaft is arranged inside the pump housing; one end of the motor shaft is connected with the outer magnetic rotor; the isolation sleeve is arranged inside the outer magnetic rotor; the inner magnetic rotor is arranged inside the isolation sleeve; one end of theinner magnetic rotor is connected with the linkage shaft; the impeller is arranged at one end of the linkage shaft; the end cover is arranged on the outer side of the impeller; the wear-resistant layer is arranged on the surface of a cavity between the end cover and the isolation sleeve; and the wear-resistant efficient horizontal centrifugal sand pump further comprises a dredging mechanism and a sealing mechanism. The invention further discloses a working method of the wear-resistant efficient horizontal centrifugal sand pump. On one hand, the space in the pump can be dredged, the problem of blockage in the pump is effectively solved, the circulation speed of equipment is high, and the effect is good; and on the other hand, multiple sealing and leakage detection are adopted, so that the problems that the equipment is poor in sealing and easy to leak are solved.

Description

technical field [0001] The invention belongs to the field of centrifugal pumps, in particular to a wear-resistant high-efficiency horizontal centrifugal sand pump and its working method. Background technique [0002] The centrifugal sand pump is mainly used to support the circulating solid control system of the oil field drilling rig, and its function is to provide drilling fluid with a certain displacement and pressure for the desander, desilter, mixer, etc., so as to ensure the efficient operation of these equipment . Since the emergence of centrifugal pumps in the 1930s and 1940s, they have been in continuous development and have been in a state of great demand in the market. Nowadays, there are more than 600 pump manufacturing enterprises in my country, with an annual output value of nearly 20 billion, which is still rising. It can be seen that the centrifugal sand pump is an indispensable equipment in modern industrial production. [0003] However, due to the huge ma...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the high viscosity of the conveying fluid, the current sand pump is prone to sticking and clogging, resulting in equipment failure and poor conveying effect

[0006] 2. Most of the current sand pumps adopt the traditional bolt and gasket sealing method, and the sealing effect is not high

[0007] 3. Most of the current sand pumps do not have the detection and response to leakage, poor practicability and low safety performance
