Metal screw pump vertical type simulation experiment method

Abstract

The invention discloses a metal screw pump vertical type simulation experiment method. The metal screw pump vertical type simulation experiment method comprises the steps that a driving system drives a pump system to work, sand containing liquid in a stirring system is sucked into a pump body by the pump system through a pumping pipeline, meanwhile, a measuring system on the pumping pipeline completes the measuring work, and then the sand containing liquid is pumped back into the stirring system by the pump system through a pumping out pipeline. The driving system and the pump system are arranged vertically, so that the fit clearance of a stator and a rotor in the pump system cannot be influenced by gravity; accordingly, the working state of the pump system in the pit is well simulated, and the movement working conditions of various mediums in the perpendicular flow direction are simulated precisely. The metal screw pump vertical type simulation experiment method has the following remarkable advantages that 1, by means of the perpendicular experiment device structure, vertical installation of the stator and the rotor is achieved, and the fit clearance of the stator and the rotor is prevented from being influenced by the gravity; and 2, the movement working conditions of the various mediums (sand, gas and the moisture content) in the perpendicular flow direction are simulated precisely.

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...
