Abstract
The invention discloses a paraffin scraping device for a pumping rod and belongs to the field of petroleum equipment. The paraffin scraping device for the pumping rod comprises a paraffin scraper, a main adjusting nut, an auxiliary adjusting nut and a short joint, wherein the main adjusting nut, the auxiliary adjusting nut and the short joint are connected sequentially, and the paraffin scraper is sleeved between the main adjusting nut and an upper circular bead of the short joint and is provided with a spiral runner. The paraffin scraping device for the pumping rod is simple in structure and convenient to mount and demount, labor intensity of workers is reduced, production management is facilitated, paraffin scraping effects are good while paraffin scraping speed is high, and removal operation can be achieved while the pumping rod is lifted. The paraffin scraping device for the pumping rod is more stable and durable by the aid of threaded connection.
Description
Technical field
The present invention relates to a kind of petroleum machinery oil production equipment field, particularly relate to a kind of device that is used for pumping rod wax scraping.
Background technology
At present, in tubing pump oil production equipment system, sucker rod is done reciprocating, in the process of transmitting axial load; Because sucker rod is the slender axles parts, in the sucker rod process, can adhere to very thick and heavy wax above the sucker rod; Therefore, needing frequent paraffin cutting, generally all is manually to carry out paraffin cutting with instrument now; Efficient is very low, and sucker rod is very elongated, and paraffin cutting is also very inconvenient.
Summary of the invention
Technical problem to be solved by this invention provides carries out the device of paraffin cutting to it when a kind of convenience is carried on sucker rod.
In order to solve the problems of the technologies described above; The present invention adopts following technical scheme: a kind of device that is used for pumping rod wax scraping; Comprise paraffin scraper, main regulation nut, secondary adjusting nut and short circuit head; Main regulation nut, secondary adjusting nut and short circuit head link in order, and paraffin scraper is set between the upper end shoulder of main regulation nut and short circuit head it, and said paraffin scraper is provided with the spiral flow passage.Paraffin scraper is because of the existence of spiral flow passage; In sucker rod pumps the course of work, because the percussion of oil stream produces the power that rotates in a circumferential direction; Make paraffin scraper, sheet rotation; Paraffin scraper and tube inner wall evenly rub, and have both prevented sucker rod generation eccentric wear, can play the paraffin cutting effect to oil pipe again.
As preferably, said main regulation nut, secondary adjusting nut and short circuit head are through the screw thread link.Make device more firm, dismounting is also simple and convenient.
As preferably, for the convenience of installation and removal, the surfaces externally and internally of said short circuit head is provided with screw thread.
As preferably, supportingly on the said main regulation nut be provided with cubic spanner.The design of spanner is for more laborsaving when screwing or unclamping nut, and is quicker.
As preferably, supportingly on the said short circuit head be provided with cubic spanner.The design of spanner is for more laborsaving when screwing or unclamping nut, and is quicker.
The present invention is a kind of, and to be used for the apparatus structure of pumping rod wax scraping simple, and easy accessibility has alleviated working strength of workers, has made things convenient for production management, and paraffin cutting is effective, speed is high, and can realize removing work when carrying sucker rod last; Employed screw thread link makes device more firm, durable in the device.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further explain.
Fig. 1 is that a kind of device that is used for pumping rod wax scraping of the present invention is installed simple structural representation.
Wherein, Reference numeral: 1 is paraffin scraper, and 2 is the main regulation nut, and 3 is the good fortune adjusting nut, and 4 is short circuit head.
The specific embodiment
Disclosed arbitrary characteristic in this manual (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
As shown in Figure 1; A kind of device that is used for pumping rod wax scraping of the present invention; Comprise paraffin scraper 1, main regulation nut 2, secondary adjusting nut 3 and short circuit head 4; Main regulation nut 2, secondary adjusting nut 3 and short circuit head 4 link in order, and paraffin scraper 1 is set between the upper end shoulder of main regulation nut 2 and short circuit head 4 it, and said paraffin scraper 1 is provided with the spiral flow passage.
Link through screw thread like a kind of main regulation nut 2, secondary adjusting nut 3 and short circuit head 4 that is used for the device of pumping rod wax scraping of Fig. 1 the present invention.
Surfaces externally and internally like the short circuit head 4 of a kind of device that is used for pumping rod wax scraping of Fig. 1 the present invention is provided with screw thread.
Supportingly on the main regulation nut 2 like a kind of device that is used for pumping rod wax scraping of Fig. 1 the present invention be provided with cubic spanner.
Supportingly on the short circuit head 4 like a kind of device that is used for pumping rod wax scraping of Fig. 1 the present invention be provided with cubic spanner.
The present invention is a kind of, and to be used for the apparatus structure of pumping rod wax scraping simple, and easy accessibility has alleviated working strength of workers, has made things convenient for production management, and paraffin cutting is effective, speed is high, and can realize removing work when carrying sucker rod last; Employed screw thread link makes device more firm, durable in the device.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
