Abstract
The utility model relates to a sand and dirt preventing efficiency-enhanced oil well pump, and belongs to the field of oil production equipment. The sand and dirt preventing efficiency-enhanced oil well pump comprises a plunger assembly and a pump cylinder assembly, wherein the plunger assembly comprises an anti-breakage traveling valve cover, an upper part plunger, an upper part traveling valve cover, a traveling valve cover joint, a plunger body, a lower part traveling valve cover and a lower traveling valve cover joint which are arranged from the top down; the pump cylinder assembly comprises a guide coupling, a sand settling pipe, an upper pump cylinder coupling, a pump cylinder, a lower pump cylinder coupling, a fixed valve cover and a fixed valve cover joint which are connected with one another from the top down in sequence; a traveling valve set is arranged in the space between the upper part traveling valve cover and the traveling valve cover joint; a fixed valve set is arranged in the space formed between the fixed valve cover and the fixed valve cover joint. The sand and dirt preventing efficiency-enhanced oil well pump adopting the structure has the advantage that the pump clamping phenomenon caused by sand and dirt settled in the pump cylinder is avoided effectively.
Description
Technical field
The utility model relates to a kind of sand-preventing scale-preventing synergistic oil pump, belongs to the oil production equipment field.
Background technique
Oil well pump is a link important in underground equipment in the petroleum production industry.The conventional oil well pump of current domestic use is comprised of pump barrel assembly and plunger piston assembly.Its pump barrel assembly upper end connects the tubing string in oil well by upper box cupling, and lower end standing valve joint directly connects the bottom tubing string, and plunger piston assembly connecting with pumping rod post, moved up and down oil recovery process with it.In oil recovery process, if in fluid, contain sand grains and dirt, can be deposited on pump barrel inside, cause the holddown phenomenon, and then cause the oil well operation accident, to oil extraction operation, cause very large loss.
Summary of the invention
The purpose of this utility model will provide a kind of sand-preventing scale-preventing synergistic oil pump to solve above problem exactly.The utility model is simple in structure, and design concept is ingenious, and novel form is convenient to manufacture.
The technological scheme that the utility model provides is:
The sand-preventing scale-preventing synergistic oil pump, comprise plunger piston assembly and pump barrel assembly, anti-breaking nomadic valve cover, top plunger, top nomadic valve cover, travelling valve shield joint, plunger body, bottom nomadic valve cover and lower nomadic valve cover joint arrange the formation plunger piston assembly from top to bottom; Drive ring, sand sediment pipe, top pump barrel box cupling, pump barrel, bottom pump barrel box cupling and standing valve cover and standing valve shield joint connect to form the pump barrel assembly from top to bottom successively; The traveling valve pair is arranged in the space of top nomadic valve cover and travelling valve shield joint formation, and the standing valve pair is arranged in the space between standing valve cover and standing valve shield joint.
Concrete, in the ring set space between top plunger and sand sediment pipe, be provided with centering ring.
Concrete, sand launder is scraped on the plunger body surface.
Preferably, plunger piston assembly length is greater than the pump barrel assembly.
The utility model plunger piston assembly length is greater than pump barrel length, makes sand grains avoid falling into pump barrel inside, and sand launder is scraped on the plunger body surface, can constantly scrape the dirt of pump barrel internal surface, is unlikely to be deposited on the pump barrel internal surface.Pump barrel top is provided with sand sediment pipe, and the sand grains that plunger is taken out of and dirt can be deposited in this space.This structure has effectively prevented the holddown phenomenon caused due in sand grains and dirt deposition pump barrel.

Embodiment
The sand-preventing scale-preventing synergistic oil pump, comprise plunger piston assembly and pump barrel assembly, anti-breaking nomadic valve cover, top plunger, top nomadic valve cover, travelling valve shield joint, plunger body, bottom nomadic valve cover and lower nomadic valve cover joint arrange the formation plunger piston assembly from top to bottom; Drive ring, sand sediment pipe, top pump barrel box cupling, pump barrel, bottom pump barrel box cupling and standing valve cover and standing valve shield joint connect to form the pump barrel assembly from top to bottom successively; The traveling valve pair is arranged in the space of top nomadic valve cover and travelling valve shield joint formation, and the standing valve pair is arranged in the space between standing valve cover and standing valve shield joint.
In ring set space between top plunger and sand sediment pipe, be provided with centering ring.
Sand launder is scraped on the plunger body surface.
Plunger piston assembly length is greater than the pump barrel assembly.
In drive ring, sand sediment pipe, top pump barrel box cupling and pump barrel, form an annular sand setting space.By the sand launder of scraping on plunger body, sand grains and dirt are scraped, and deposit in annular sand setting space.Prevent the holddown phenomenon caused due in sand grains and dirt deposition pump barrel.
