A vertical simulation experiment method of metal screw pump

Abstract

The invention discloses a vertical simulation experiment method of a metal screw pump. The drive system drives the pump system to work, and the pump system sucks the sand-containing liquid in the stirring system into the pump body through the pumping pipeline, and pumps it into the pipeline for metering at the same time. The system completes the metering work, and then the pump system pumps the sandy liquid back into the mixing system through the pumping pipeline; due to the vertical setting of the drive system and the pump system, the fit clearance of the stator and rotor in the pump system will not be affected by gravity , and then well simulate the working state of the pump system in the well, and realize the accurate simulation of different media movement conditions in the vertical flow direction. The present invention has the following remarkable advantages: 1. Vertical experimental device structure: the vertical installation of the stator and rotor is realized, which avoids the influence of gravity on the fit gap of the stator and rotor; 2. Different media (sand, gas, moisture content ) accurate simulation of motion conditions.

Description

technical field [0001] The invention relates to a simulation experiment method of an oil field screw pump, in particular to a vertical simulation experiment method of a metal screw pump. Background technique [0002] Affected by its own weight, the stress of the screw pump rotor is concentrated on the stator part near the ground, especially in high-speed, sandy operating conditions, which will increase the wear of the rotor on the stator. In order to better simulate the working state of the screw pump in the well, more To accurately grasp the wear resistance characteristics of screw pumps under the condition of adding sand, it is necessary to design a new vertical simulation experiment method for metal screw pumps. Contents of the invention [0003] The purpose of the present invention is to provide a metal screw pump vertical simulation experiment method, which overcomes the fact that when the existing horizontal test bench is running, the rotor is concentrated on the sta...
