Abstract
The utility model discloses a rubber sealing device of an oil extractor in an oil field, which consists of an upper rubber packing box, a lower rubber packing box, rubber sealing rings and lubricating oil, wherein the rubber sealing rings are respectively arranged in the upper rubber packing box and the lower rubber packing box and are in semi-ring structures; and the bottom portions of the sections of the rubber sealing rings are in point contact with the lower rubber packing box. The overall dimension of each rubber sealing ring is slightly greater than the inside diameter of the upper rubber packing box and the inside diameter of the lower rubber packing box; and lubricating agents are respectively coated in the upper packing box and the lower packing box. The rubber sealing device has the advantages that the rubber sealing rings can be prevented from being damaged in the mounting process and the ambient environments of the rubber sealing rings are protected. The lubricating agents can well cure the rubber sealing rings and prevent and delay the ageing of the rubber sealing rings at the abnormal temperature. The bottom portions of the sections of the rubber sealing rings are in point contact with the low rubber packing box so as to generate an included angle space for impurities to stay and further prevent pollutants from being accumulated on the surfaces of the rubber sealing rings. By adopting larger overall dimensions, the rubber sealing device is conductive to bearing the load and prolonging the service life of the rubber sealing rings.
Description
Technical field
The utility model relates to a kind of oil-field oil pumper rubber sealing device, is applicable to the transmission shaft sealing of oil field with speed reducer on the pumping unit.
Background technique
Pumping unit is the oil production equipment that generally use in each oil field of China, because these pumping units are all turning round all the year round incessantly, its wearing and tearing of seal arrangement that are contained in the speed reducer flange are quickish, thereby the oil leakage phenomenon of pumping unit can often take place.Especially at the northern area of China, be operated in pumping unit under the open-air environment more to stand throughout the year in freezing winter and in sultry summer, wind and weather, the fault that leakage of oil appears in pumping unit is easier the generation just.Pumping unit generation leakage of oil not only can cause a large amount of crude oil losses, also can cause serious pollution to environment on every side simultaneously.Because pumping unit quite disperses in the distribution of oil-producing region, most of pumping units all are away from maintaining unit, these wearout parts unit of sending back to maintenances can be had a strong impact on crude output, and its difficulty of in-situ processing is quite big, therefore people press for a kind of especially can be wear-resistant, the pumping unit seal arrangement that equipment failure and maintenance are low can realize that at present the product of this target is also quite rare.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of pumping unit seal arrangement.This device has multinomial seal protection measure, can prolong the working life of rubber seal widely.
The technical solution of the utility model is: this pumping unit seal arrangement is except that having rubber seal, also comprise upper and lower rubber packing box, rubber seal is contained in the upper and lower rubber packing box, is semi-loop, contacts for point between the bottom of its section and following rubber packing box.The Outside Dimensions of rubber seal is slightly larger than the internal diameter of upper and lower rubber packing box, scribbles oiling agent in upper and lower rubber packing box.
The topmost advantage of the utility model is exactly the protective measure that has increased rubber seal, at first be to have designed upper and lower rubber packing box, the one, can prevent that rubber seal is damaged in installation process, the 2nd, can protect the cleaning of rubber seal surrounding environment; The second measure is to have increased oiling agent in upper and lower rubber packing box, and this oiling agent can play good maintenance action for rubber seal, can prevent and delay especially that the rubber seal loop material takes place under abnormal temperature is aging; The 3rd, contact for point between the bottom of rubber seal section and following rubber packing box, can produce one in its both sides can be for the angle space of impurity stop, can prevent further that like this pollutant from accumulating on the rubber seal surface, adopt bigger Outside Dimensions to help the bearing load effect, can prolong the working life of rubber seal.In addition, the design has also adopted several novel macromolecular materials, all can reach cold-resistant, heat-resisting, oil resistant, physics and chemistry machinery index such as water-fast, acidproof, alkaline-resisting, wear-resisting in the intervals at subzero 50 degree to 50 degree above freezing, reached as high as 1200 hour greater than 720 hours working life.
