Abstract
The utility model relates to a device for lubricating a polish rod of an oil pumping unit. The device consists of a polish rod sealer body, an oil supply gun, a lubricating oil ring, a packing and the polish rod, wherein an annular oil slot and an oil passing through hole are formed in the inner pipe wall of the body; the lubricating oil ring is sleeved on the polish rod corresponding to the annular oil slot; and the oil passing through hole is connected with the oil supply gun through a check valve and a high-pressure hose. Lubricating oil can be directly pressed into friction surfaces of the polish rod and the packing through the oil supply gun, so that the friction surfaces are effectively lubricated; furthermore, the service life of the packing is prolonged, and the well drilling time rate is increased.
Description
Technical field
The utility model relates to petroleum beam-pumping unit well head water-tight equipment, particularly a kind of oil-extractor polish-rod lubricating arrangement.
Background technology
In the present oil exploitation, oil pumping polish rod is done in mouth of pumped oil well and is pumped, and the main inside of sealing problem between the two is equipped with that the sealer of packing realizes.And at present be to utilize the crude oil of output on polished rod, to form to adhere to oil film rubbing surface is lubricated between polished rod and the packing.But because a lot of oil field is in the exploitation middle and later periods, the liquid aqueous height of output, these wells are difficult to adhere to oil film on polished rod; Be in the dry type friction between polished rod and the packing for a long time; Quicken the wearing and tearing of oil pumping polish rod and packing, can cause the burning packing when serious, needed frequent replacing oil pumping polish rod and the packing body in the sealer; Not only increase the maintenance cost of mouth of pumped oil well, and influenced the oil pumping well yield.
Chinese patent 200820026831.6 disclosed " oil-extractor polish-rod lubricating coupler " is made up of fuel feeding bucket and seating nipple, can realize the continuous lubrication to packing.But fuel feeding bucket and packing_seal device are the design of one, cause dismounting and load butter inconvenience.Installation work tube in the sealer simultaneously, bigger to the transformation of sealer, cost is higher, is unfavorable for that the scene promotes the use of.
Summary of the invention
The utility model purpose 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.
To achieve these goals; The oil-extractor polish-rod lubricating coupler of the utility model is made up of polished rod sealer body, fuel feeding rifle, splash ring, packing, polished rod; On the inner tubal wall of body, be provided with annular oil groove and cross oil hole; With the corresponding polished rod of annular oil groove on be with splash ring, cross oil hole and be connected with the fuel feeding rifle through ball-and-seat, high-pressure hose.
Described splash ring is a hollow tubular body, has oil-through hole on its tube wall; Oil-through hole can be distributed on the tube wall of splash ring.
The fuel feeding rifle is a hollow tubular body, and its upper and lower end is connected with bottom end cover with upper end cover through screw thread respectively, and upper end cover is provided with reducer coupling and is connected with high-pressure hose; Spring and piston are installed on the bottom end cover successively.
Described fuel feeding rifle is fixed on the polished rod sealer body through clamp.
The utility model has following advantage compared with prior art: 1, splash ring is installed in the middle of the packing, ensures that lubrication oil gets into the rubbing surface of polished rod and packing, prevents oil leak simultaneously.2, because packing has obtained effective lubricating, increase the application life of packing, improved rate when driving a well.3, simple in structure, easy to manufacture, cost is low, removes and installs conveniently, can be widely used in various oil pumper well heads.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The oil-extractor polish-rod lubricating coupler of the utility model is made up of polished rod sealer body 1, fuel feeding rifle 2, splash ring 3, packing 5, polished rod 10; On the inner tubal wall of body 1, be provided with annular oil groove 4 and cross oil hole 6; With annular oil groove 4 corresponding polished rods 10 on be with splash ring 3, cross oil hole 6 and be connected with fuel feeding rifle 2 through ball-and-seat 7, high-pressure hose 8.
Described fuel feeding rifle 2 is a hollow tubular body, and on it, upper and lower side is connected with bottom end cover 12 with upper end cover 13 through screw thread respectively, upper end cover 13 is provided with reducer coupling and is connected with high-pressure hose 8; Spring 15 and piston 14 are installed on the bottom end cover 12 successively.
Described fuel feeding rifle 2 is fixed on the sealer body 1 through clamp 9.
Inject butter in the cavity between piston 14 and upper end cover 13; Under the effect of the spring 15 of butter in fuel feeding rifle 2 and piston 14; Through high-pressure hose 8, ball-and-seat 7, mistake oil hole 6, annular oil groove 4, oil-through hole 11; Get into the inner chamber of splash ring 3, the butter that reciprocating polished rod 10 is consumed replenishes, and realizes continuous lubrication.Ball-and-seat can ensure the lubrication oil one-way flow, prevents the oil and gas leakage in the polished rod sealer body 1.
