Oil field oil pump sand scraping device and manufacturing method thereof

Abstract

Disclosed are an oil field oil pump sand scraping device and a manufacturing method thereof. According to the technical scheme, the oil field oil pump sand scraping device with a sand scraping function is designed and located between an upper travelling ball cover and an upper travelling valve joint of an oil-well pump, so that sand grains in crude oil do not enter the position between a plunger and a pump barrel; the oil field oil pump sand scraping device is composed of a sand hole straight-through joint and a scraper ring; the sand hole straight-through joint is of a tubular straight through structure, and an upper end opening of the sand hole straight-through joint is provided with an upper screw opening, a lower end opening of the sand hole straight-through joint is provided with a lower screw opening, a cutter groove is formed in the middle of the sand hole straight-through joint, and a sand return hole is formed in the cutter groove; the scraper ring is in a circular-ring shapeand provided with a cutter ring seam, so that a ring opening is enlarged conveniently during mounting; and the section of an annular reinforcement is prismatic, the inner diameter wall is low and theouter diameter wall is high, and two cutter edges are formed on the upper portion and the lower portion of the annular reinforcement. The oil field oil pump sand scraping device has the beneficial effects that the problem that the oil field oil pump sand scraping device is jammed and crashed due to precipitation of the sand grains in the crude oil in an upper opening of the plunger of the oil-wellpump can be solved, and the working efficiency of the oil-well pump is improved.

Description

technical field [0001] The invention relates to a manufacturing method of an oilfield oil recovery equipment accessory. , especially an oilfield oil pump sand 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, be...
