Abstract
The utility model relates to an energy-saving lubricating device for an oil pumping unit polish rod, and mainly solves the problems that a packing and a cursor are easy to wear, and service life of the packing and the cursor is shortened due to the fact that an existing oil pumping unit packing has large frictional force. The energy-saving lubricating device for the oil pumping unit polish rod is characterized in that the upper portion of a packing box (4) is in threaded connection with a pressing packing nut (1), a grease bag support seat (3) is arranged inside the pressing packing nut (1), a blocking packing (2) is disposed between the pressing packing nut (1) and the grease bag support seat (3), an oil inlet packing gland (5) is arranged between the grease bag support seat (3) and a sealing packing (7) on the lower portion of the packing box, and a grease nipple (6) is connected with a side wall of the packing box (4) and corresponding to the oil inlet packing gland (5). The energy-saving lubricating device for the oil pumping unit polish rod has the advantages of being good in lubricating effect and little in frictional force, and prolonging the service life of the packing and the cursor.
Description
Technical field
The utility model relates to the field, oil field, a kind of specifically oil-extractor polish-rod Saving Energy by Lubrication device.
Background technology
The rod-pumped well submergence is less than 50 meters; Flowing pressure less than the well of 2.0 MPas in the process of each hot clean-up well, because hot clean-up well delivery side of pump pressure is added the pressure and hydrostatic pressure in the pit shaft, and the damming of pump intake; Cause the water yield of most hot clean-up well to inject oil reservoir earlier; The water yield of next again by deep well pump to ground because the theoretical displacement of pump is less, the water that injects oil reservoir needed just can exhaust in many days.And because water cannot not cooperate lubricatedly with packing with polished rod, mainly there is following problem in deep well pump in process of production when drawing water: the one, and the frictional resistance that the packing box place produces when drawing water increases, and the power consumption energy is big, and system effectiveness descends, and energy-saving effect is poor; The 2nd, the packing rate of wear is accelerated, and adds the increased frequency of packing, and waste material increases personnel labor; The 3rd, the position diameter of polished rod stroke is levigate, if transfer big stroke, this polished rod can not reuse; The 4th, polished rod and packing are not lubricated when drawing water, and packing adds incessantly, and packing box emits water, brings difficulty to production management.
Summary of the invention
The deficiency that existing oil pumper packing frictional force causes packing greatly and cursor is easy to wear in order to overcome, shorten the application life of packing and polished rod; The utility model provides a kind of oil-extractor polish-rod Saving Energy by Lubrication device, and this oil-extractor polish-rod Saving Energy by Lubrication device has the advantages that high lubricating effect, frictional force are little, prolong the application life of packing and polished rod.
The technical scheme of the utility model is: a kind of oil-extractor polish-rod Saving Energy by Lubrication device; Comprise packing box and inner sealed packing thereof; Described packing box top is threaded and compresses the packing nut; Compress packing nut inside and be provided with butter capsule supporting seat, compress between packing nut and the butter capsule supporting seat and be equipped with the shutoff packing, be provided with the oil-feed packing gland between the sealed packing of butter capsule supporting seat and bottom; Be connected with grease nipple on the described packing box sidewall, and grease nipple is corresponding with the oil-feed packing gland.
Described butter capsule supporting seat inside is cavity.
Described grease nipple is embedded in the packing box sidewall.
The utlity model has following beneficial effect: owing to take such scheme, on the packing box sidewall grease nipple is installed, can be through grease nipple to the inner butter of annotating of packing box; And it is inner that butter can be stored in butter capsule supporting seat, when polished rod moves up and down, just can the butter in the lubricating arrangement be brought in the packing; Thereby alleviate the frictional force of polished rod and packing, improve lubricant effect, improve system effectiveness; Prolong the application life of packing, polished rod; Prolong the application life of packing, polished rod, alleviate working strength of workers, improved managerial skills.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1, a kind of oil-extractor polish-rod Saving Energy by Lubrication device comprises packing box 4 and inner sealed packing 7 thereof; Described packing box 4 tops are threaded and compress packing nut 1; Compress packing nut 1 bottom and place packing box 4 inside, top places packing box 4 tops, compresses packing nut 1 inside and is provided with butter capsule supporting seat 3; Described butter capsule supporting seat 3 inside are cavity; Form the butter capsule that stores butter, compress between packing nut 1 and the butter capsule supporting seat 3 and be equipped with shutoff packing 2, can prevent that the butter in the butter capsule from leaking outside.Be provided with oil-feed packing gland 5 between the sealed packing 7 of butter capsule supporting seat 3 and bottom; Described oil-feed packing gland 5 sidewalls are provided with several apertures; And there is cavity its inside, is connected with grease nipple 6 on described packing box 4 sidewalls, and grease nipple 6 is corresponding with the cavity in the oil-feed packing gland 5; The butter that is injected by grease nipple 6 can enter into butter capsule supporting seat 3 and be stored in its inside through oil-feed packing gland 5.Described grease nipple 6 is embedded in packing box 4 sidewalls, can prevent that like this grease nipple 6 is destroyed.Packing box 4 be externally connected to handle 9, make and install and convenient disassembly.
When oil pumper is worked, when polished rod moves up and down through this lubricating arrangement, can the butter in the butter capsule be brought in the sealed packing 7; Thereby alleviate the frictional force of polished rod and packing, improve lubricant effect, economize on electricity, raising system effectiveness; And prolong the application life of packing, polished rod; Prolong the application life of packing, polished rod, alleviate working strength of workers, improved managerial skills.
