Problems solved by technology

Since the diameter of the plunger is reduced from 32mm or 38mm to 25mm, the reduction of the plunger diameter will increase the deflection of the long plunger when turning the outer circle, resulting in increased deformation of the processed workpiece, increased processing difficulty, and improved processing accuracy.

Abstract

The invention discloses a small-diameter long plunger processing device and a processing method thereof, and belongs to the technical field of oil production engineering. A track underframe is fixed on the level ground through a ground screw; a tendency track is fixed on the track underframe through a bolt; a straightening block mechanism is mounted on the track underframe, positioned at the front ends of anti-shake guide wheels, and capable of moving along the tendency track; the anti-shake guide wheels are fixed on the track underframe; travelling sliding sleeves of the anti-shake guide wheels sleeve the tendency track in a clearance fit manner; a sliding base is positioned on the tendency track and can move frontwards and backwards along the tendency track; and a motor system is fixed on the sliding base and the tendency track is connected with a tailstock.

Description

technical field [0001] The invention relates to a small-diameter long plunger processing device and a process method, belonging to the technical field of oil recovery engineering. Background technique [0002] Rod pump oil production of pumping unit is an artificial lifting oil production method, which is widely used in major oil fields at home and abroad for its advantages of simple equipment, low investment, convenient management, and strong adaptability. The oil pump is the key downhole equipment of the rod pump oil production system. It is installed at the lower part of the tubing string, submerged in the well fluid, and the oil is discharged to the ground by pumping. Oil well pump is mainly composed of pump barrel, plunger, fixed valve and floating valve. The pump barrel is the cylinder liner, and the plunger with the traveling valve is housed in it. The plunger forms a seal with the pump barrel for expelling fluid from the pump barrel. [0003] In recent years, due ...
