Abstract
A bearing type self-lubricating sealer for a polish rod comprises a fixing screw nut, a positioning screw, a pressing cover, a pressure bearing, a pressing cap, a packing box, packing, an oil storage box, a grease fitting, a rubber gate and a hoop head. The whole bearing type self-lubricating sealer is in a cross shaped structure, the longitudinal section of the pressing cover is in a shape like a Chinese character 'tu', and the center of the bearing type self-lubricating sealer is provided with a polish rod through hole. The pressure bearing is sleeved on the pressing cover, penetrates through the center of the pressing cap, and is fixed through the fixing screw nut and locked through the positioning screw. The pressing cap is in threaded connection with the upper portion of the packing box. A barrier is arranged at the lower portion of a cavity of the packing box, the packing is filled between the pressing cover and the barrier, and the oil storage box is arranged in the middle of the packing. The grease fitting is arranged at the position of the oil storage box right facing the packing box, the rubber gate is arranged at the lower portion of the packing box, and the hoop head or internal threads are arranged at the bottom of the packing box. Grease can be filled in the packing, and the packing has long service life. Furthermore, friction load of an oil pumping unit and loss of crude oil are reduced, electricity energy is saved, and environment pollution is avoided. When the packing is screwed, time and labor are saved and work strength of workers is reduced.
Description
Technical field
The utility model relates to oil well oil-pumping wellhead polish rod sealing device, particularly is a kind of bearing-type self-lubricating polished rod sealer.
Background technology
Rod-pumped well in process of production, the sealing of polished rod and well head is accomplished by polished rod sealer, the polished rod sealer model is more at present; No matter common polished rod sealer still is the tuningout polished rod sealer, and the packing inside butter of all can not annotating causes the packing serious wear; Application life is short, causes well head leakage of oil, particularly high water-cut well especially serious; Not only cause the crude oil loss, and contaminated environment.Adopt planar friction between polished rod sealer pressure cap and the gland in addition, frictional resistance is big, tight packing difficulty.Thereby prior art can not solve the problems of the technologies described above preferably.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of bearing-type self-lubricating polished rod sealer is provided.
The utility model technical scheme comprises: Fixed Nut, dog screw, gland, pressure bearing, pressure cap, packing box, packing, oil storage box, grease nipple, rubber gate, clip head; Its bearing-type self-lubricating polished rod sealer is " ten " font structure, and the vertical section is the gland of " protruding " font, and the center is provided with the polished rod through hole, and pressure bearing is enclosed within on the gland, pass from the pressure cap center, by Fixed Nut fix, dog screw locking; Pressure cap and packing box top thread connection, packing box inner chamber bottom are provided with at a distance from blue, between gland and the separated orchid packing are housed; Be provided with oil storage box in the middle of the packing; On packing box, over against the oil storage box place grease nipple is housed, so that the filling butter, the packing box bottom is the rubber gate; The bottom is provided with clip head or internal thread, so that connect with well head.
Oil storage box in the above-mentioned bearing-type self-lubricating polished rod sealer is a circular ring type, and the center is the polished rod through hole, and annulus is provided with four oil storage holes.
The beneficial effect of the utility model is: the packing inside butter of can annotating, and the packing long service life reduces the oil pumper frrction load, and saves energy reduces the crude oil loss, avoids contaminated environment.Change rolling friction into by planar friction between polished rod sealer pressure cap and the gland, frictional resistance is little, and tight packing is time saving and energy saving, alleviates working strength of workers.
