Abstract

The invention provides an upward scraping device for an oilfield oil pump and a manufacturing method thereof. According to the technical scheme, the upward scraping device for the oilfield oil pump isdesigned and used for scraping sand. The device is arranged between an upstream movable spherical cover and an upstream movable valve joint of the oil pump; stand in crude oil cannot enter between aplunger piston and a pump barrel through the device. The device comprises a sand hole through joint and a scraping cutter ring, wherein the sand hole through joint is in a tubular through form; an upper end port of the sand hole through joint is provided with an upper screw port; a lower end port of the sand hole through joint is provided with a lower screw port; a cutter groove is formed in the middle part of the sand hole through joint, and a sand returning hole is formed in the cutter groove; the scraping cutter ring is annular and is provided with a cutter ring seam, and a ring opening canbe conveniently expanded during mounting; the sections of ring ribs are prismatic; the inside diameter walls of the ring ribs are low, and the outside diameter walls of the ring ribs are high; two blades are formed in the top parts and the bottom parts of the ring ribs. The device has the beneficial effects that the problem of locking and halting caused by sand deposition in crude oil in an upperport of a plunger piston of the oil pump can be solved, and thus the working efficiency of the oil pump can be improved.

Description

technical field [0001] The invention relates to a manufacturing method of an oilfield oil recovery equipment accessory. , especially an oil well pump scraping device and a manufacturing method thereof. Background technique [0002] The oil pump is a common oil pumping equipment for pumping the crude oil in the well to the ground. The existing oil pump mainly consists of an upper moving ball cover, an upper sealing ball, an upper sealing ball seat, an upper fixed valve joint, and an upper moving valve joint. , plunger, pump barrel, middle-swimming valve cover, middle sealing ball, middle sealing ball seat, sealing seat cover, middle fixed valve joint, lower fixed valve cover, lower sealing ball, lower sealing ball seat, lower fixed valve joint The oil pumping method is to lift the crude oil from a low place to a high place through the up and down movement of the plunger and pump the crude oil from the bottom of the well to the top of the well and out of the well, because the...
