All-metal screw pump stator machining equipment

Abstract

The invention discloses all-metal screw pump stator machining equipment. The all-metal screw pump stator machining equipment comprises a cutter bar, a cutter head, a guide rod, a supporting base, a workpiece fixing device and a cutter bar rotation driving device, wherein the supporting base is fixedly connected with a machine tool; a guide sleeve is arranged on the guide rod; a guide slot is formed on the guide rod; the guide rod is arranged on the supporting base; the cutter bar is arranged inside the guide slot through an adjustable shaft sleeve; the cutter head is arranged at the front end of the cutter bar; the back end of the cutter bar is connected with the cutter bar rotation driving device; the cutter bar is equipped with a translational mechanism moving in the radial direction of the guide slot; at least one axial air hole is formed on the guide rod; the outlet of the axial air hole is formed on the front end surface of the guide rod; the inlet of the axial air hole is connected with an air supplying device; an axially communicated cooling oil hole is formed in the center of the cutter bar; and a cooling oil supplying device is connected at the back end of the cooling oil hole. The all-metal screw pump stator machining equipment has the advantage as follows: metal scraps are discharged from a cutting point, thus avoiding the problems such as abrasion of the cutter head and blade flaking, and preventing defects of an internal hole caused by scratch of the internal hole by the metal scraps.

Description

technical field [0001] The invention relates to a processing device for an all-metal screw pump, in particular to a processing device for a stator of an all-metal screw pump. Background technique [0002] As a new technology with great potential and advantages in downhole mining technology, screw pump has been more and more widely used in various oil fields in the world in recent years. It has the characteristics of small initial investment, simple structure of ground driving device, convenient installation, small footprint and high pump efficiency. At present, the application of screw pumps is mainly concentrated in several major fields such as heavy oil cooling pumps, sand production reservoirs, offshore platforms, energy conservation and environmental protection. The traditional screw pump stator is made of nitrile rubber lining in the steel sleeve. But this kind of rubber stator screw pump usually can only cope with the normal work of low speed, low viscosity and low t...

AI Technical Summary

Problems solved by technology

However, due to the long length of the stator, the following disadvantages will occur: one is that the cutting metal chips cannot be effectively discharged, so it will cause knife punching and blade chipping, and the inner hole is easily scratched by metal chips to cause defects. It is difficult to lubricate the tool, so the life of the tool is very low, so the device cannot really be used for the machining of the stator cavity
