Abstract
The invention relates to the oilfield oil extraction equipment manufacturing technical field, in particular to a ceramic plunger. To overcome the problem of blockage of an oil pump in the prior art caused by the heating and deformation of a metal plunger, the invention provides the ceramic plunger which comprises a top ring, a spacing ring, a ceramic plunger barrel, an oil pumping pipe and a ball valve; one end of the top ring has a sunken conical surface; two ends of the ceramic plunger barrel have protuberant ceramic conical surfaces, two ends of the spacing ring have sunken conical surfaces; one end of the ball valve is fixedly connected with a middle check nut; the other end of the ball valve is provided with a spring seat; the spring seat is provided with a spring seat liner inside; the spring seat is connected with the spring seat liner by a spring seat pin; and a spring is arranged between the spring seat and the spring seat liner. The ceramic plunger lightens the vertical impulsive force when the plunger bumps the pump, eliminates the extrusion to the ceramic plunger barrel when the metal top ring, the spacing ring and the oil pumping pipe are heated and expanded, and protects the ceramic plunger barrel from being broken easily.
Description
Technical field
The present invention relates to the manufacturing technology field of oil field equipment, be specifically related to a kind of ceramic plunger.
Background technique
Oil well pump is one of capital equipment in the well recovery system, and plunger is the critical component of oil well pump, and existing thick oil steam drive oil well is in the process of recovering the oil with oil well pump, and the metal plunger temperature distortion causes holddown, influences oil well production.Though have excellent heat-resisting quantity, very high chemical stability and wear resistance with the plunger of stupalith manufacturing, pottery enbrittles, cracked easily and damage, therefore must make special structural design, could satisfy demand of practical production.
Summary of the invention
The present invention is in order to overcome the oil well pump that exists in the prior art because of the holddown problem that the metal plunger temperature distortion causes, and a kind of ceramic plunger of high temperature resistant, anticorrosive, good stability is provided.
In order to achieve the above object, the technical solution used in the present invention is: a kind of ceramic plunger, comprise apical ring, spacer ring, ceramics pole plug sleeve, oil pick-up tube, ball valve, described oil pick-up tube two ends are respectively equipped with tight cap in upper end and middle tight cap, apical ring is arranged on the outside two ends of oil pick-up tube, apical ring and ceramic plunger cover closely cooperate, spacer ring is set between the ceramics pole plug sleeve at interval, closely cooperate between ceramics pole plug sleeve and the spacer ring, its special way is: an end of described apical ring is the recessed conical surface, the conical surface of the two ends of ceramics pole plug sleeve for protruding, the two ends of spacer ring are the recessed conical surface; One end of described ball valve is fixedlyed connected with middle tight cap, and the other end is provided with spring seat, is provided with cover in the spring seat in the described spring seat, and spring seat is connected by the spring seat pin with the interior cover of spring seat, is provided with spring between the cover in spring seat and the spring seat.
The acute angle angle that the bus of the conical surface that protrude at above-mentioned ceramics pole plug sleeve two ends and circular cone center line intersect is 45 °～75 °.
The material of above-mentioned spring is a stainless steel.
Compared with prior art, advantage of the present invention is as follows:
1, be provided with spring vibration damper among the present invention, the vertical impulse force when alleviating plunger and bumping pump, protection ceramics pole plug sleeve is difficult for broken;
When 2, the present invention has eliminated metal apical ring, spacer ring and oil pick-up tube expanded by heating, to the extruding of ceramics pole plug sleeve, protection ceramics pole plug sleeve.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention.
Reference character:
The 1-apical ring, 2-spacer ring, 3-ceramics pole plug sleeve, 4-oil pick-up tube, 5-ball valve, the tight cap in 6-upper end, tight cap in the middle of the 7-, cover in the 8-spring seat, 9-spring seat, 10-spring seat pin, 11-spring.
Embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention done describing in further detail.
Referring to Fig. 1, the invention provides a kind of ceramic plunger, comprise apical ring, spacer ring, ceramics pole plug sleeve, oil pick-up tube, ball valve, described oil pick-up tube two ends are respectively equipped with tight cap in upper end and middle tight cap, apical ring is arranged on the outside two ends of oil pick-up tube, apical ring and ceramic plunger cover closely cooperate, and at interval spacer ring are set between the ceramics pole plug sleeve, closely cooperate between ceramics pole plug sleeve and the spacer ring.One end of described apical ring is the recessed conical surface, the conical surface of the two ends of ceramics pole plug sleeve for protruding, and the two ends of spacer ring are the recessed conical surface; The acute angle angle that the bus of the conical surface that protrude at above-mentioned ceramics pole plug sleeve two ends and circular cone center line intersect is 45 °～75 °.When metal apical ring, spacer ring and oil pick-up tube expanded by heating, can cause extruding to ceramics pole plug sleeve therebetween, when the cone match between apical ring, spacer ring, the ceramics pole plug sleeve can discharge metal apical ring, spacer ring and oil pick-up tube expanded by heating, to the extruding force of ceramics pole plug sleeve.
One end of described ball valve is fixedlyed connected with middle tight cap, and the other end is provided with spring seat, in the described spring seat
Be provided with cover in the spring seat, spring seat is connected by the spring seat pin with the interior cover of spring seat, is provided with stainless steel spring between the cover in spring seat and the spring seat.Vertical impulse force when the top of ceramic plunger is provided with damping device and can alleviates plunger and bump pump, protection ceramics pole plug sleeve is difficult for broken.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
