Abstract
Disclosed is a polished rod lubricator of oil pumping unit, which is composed of an oil supply cylinder and an operating cylinder; wherein, the oil supply cylinder and the operating cylinder are all cylindrical, the lower parts of the oil supply cylinder and the operating cylinder are provided with a communicating pipe, and a check valve is arranged on the communicating pipe; a pressure cap is arranged on the upper end part of the oil supply cylinder, and the lower end of the oil supply cylinder is provided with a deflation valve, a pressure plate is arranged in the oil supply cylinder and is welded with a pressure rod which run through the center of the pressure cap, a spring is arranged between the pressure cap and the pressure plate, the pressure plate is sealed and matched with the oil supply cylinder, and grease is arranged under the pressure plate; the pressure cap is arranged on the upper end of the operating cylinder, a packing separator is arranged under the pressure cap, a packing is arranged under the packing separator, grease is injected under the packing, the lower end part of the operating cylinder is provided with a female thread connected with a blowout-prevention box, and the periphery of the operating cylinder is provided with a grease inspection hole sealed by a screw. The polished rod lubricator is mounted on the upper part of the blowout-prevention box in prior art, and the structure of blowout-prevention box is not changed, so the mounting is convenient; the service life of packing is prolonged, and the replacement times of packing is reduced; no oil-leakage and pollution-free are basically realized for well mouth, the labor intensity of workers is reduced, and the production time efficiency of oil well is improved.
Description
One, technical field
The utility model relates to a kind of oil-extractor polish-rod lubricating coupler.
Two, background technology
Polished rod is lubricated at present is to be lubricated by association's band crude oil, press very tightly as packing, the crude oil band does not come up to cause easily the burning packing, after being burnt, packing just loses sealing force, must change, crude oil lubrication is arranged when polished rod is up in addition, but when descending also be and packing between be in the dry grinding process, also can cause the burning packing, it all is that these two kinds of reasons are made that packing is often changed substantially because of leakage of oil.
Three, summary of the invention
The purpose of this utility model provides a kind of oil-extractor polish-rod lubricating coupler, solves the packing weak point in application life that above-mentioned prior art exists, and often changes the problem of packing.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of fuel feeding bucket and seating nipple, and it is cylindrical to it is characterized in that fuel feeding bucket and seating nipple are made as, and is provided with on communicating pipe, communicating pipe in the bottom of fuel feeding bucket and seating nipple and is provided with ball-and-seat; Fuel feeding bucket upper end is provided with pressure cap, and the lower end is provided with vent valve, is provided with platen in the fuel feeding bucket, and the depression bar welding with passing the pressure cap center is provided with spring between pressure cap and the platen, is sealed and matched between platen and the fuel feeding bucket, and butter is housed below the platen; The seating nipple upper end is provided with pressure cap, and pressure cap bottom is provided with the packing dividing plate, and packing dividing plate bottom is provided with packing, is marked with butter below the packing, and the seating nipple bottom is provided with the box thread that is connected with the blowout prevention box, is provided with the butter inspection eye that seals with screw in all sides of seating nipple.
The center of the pressure cap of seating nipple and packing dividing plate is provided with the polished rod hole and on same center line.
The utility model compared with prior art has the following advantages:
1, be contained in the top of the former blowout prevention box of oil well, the structure that does not change the blowout prevention box is easy for installation;
2, prolong the application life of packing, reduced the number of times of changing packing, it is pollution-free that well head accomplishes not have leakage of oil substantially, reduced worker's labour intensity, the rate during production that improved oil well.

Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is made up of fuel feeding bucket 5 and seating nipple 8, and it is cylindrical to it is characterized in that fuel feeding bucket and seating nipple 5,8 are made as, and is provided with in the bottom of fuel feeding bucket and seating nipple and is provided with ball-and-seat 9 on communicating pipe, communicating pipe; Fuel feeding bucket upper end is provided with pressure cap 2, and the lower end is provided with vent valve 6, is provided with platen 4 in the fuel feeding bucket, and depression bar 1 welding with passing pressure cap 2 centers is provided with spring 3 between pressure cap and the platen, be sealed and matched between platen and the fuel feeding bucket, and butter is housed below the platen; The seating nipple upper end is provided with pressure cap 12, pressure cap bottom is provided with packing dividing plate 11, and packing dividing plate bottom is provided with packing 10, is marked with butter below the packing, the seating nipple bottom is provided with the box thread that is connected with the blowout prevention box, is provided with the butter inspection eye 7 that seals with screw in all sides of seating nipple.
When using the utility model, it is enclosed within on the polished rod connects with the blowout prevention box, unload the depression bar 1 of fuel feeding bucket 5, pressure cap 2, platen 4 and spring 3, open vent valve 6, in the fuel feeding bucket, fill it up with butter, shut vent valve, in seating nipple 8, press butter with depression bar and platen earlier, butter enters seating nipple through ball-and-seat 9, this moment, pressure cap 12 packing dividing plates 11 packings 10 of seating nipple all installed, when treating that the butter inspection eye goes out butter on the seating nipple, again the fuel feeding bucket were filled it up with butter again depression bar, pressure cap, spring and platen are installed in together for bucket and upward get final product, when in the seating nipple during butter loss, spring presses platen to replenish butter in trend work.
