Abstract
The utility model discloses a dual sealing device of an oil cylinder. The dual sealing device comprises a cylinder cover and a sealing device, wherein the sealing device is arranged on the cylinder cover, and the sealing device comprises a first sealing zone, an oil storage tank and a second sealing zone. The oil storage tank is arranged between the first sealing zone and the second sealing zone. An oil storage tank arranged between two sealing zone minimizes dry friction of the second sealing zone, thereby reducing product loss, and accelerating work schedule. Moreover, the dual sealing device is simple in structure.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly relates to a kind of double-sealing device of oil cylinder.
Background technique
In the industrial production in modern times; usually can use seal arrangement; the effect of seal arrangement prevents that the liquid of machine intimate or gas from letting out between the junction plane of two parts, the 2nd, prevent outside impurity, dust intrusion, and keep the necessary environment of mechanical parts normal operation.
The double-sealing device of oil cylinder in the market, structure is more single, and in long-time practical situation, the second sealing area can produce dry friction, affects easily job schedule, causes unnecessary trouble.
The model utility content
The technical problem that the utility model mainly solves provides a kind of double-sealing device of oil cylinder, can also can not cause dry friction in situation about working long hours, and has improved job schedule, and simple in structure.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: the double-sealing device that a kind of oil cylinder is provided, comprise: cylinder cap, seal arrangement, described cylinder cap place is provided with seal arrangement, described seal arrangement comprises first sealing area, oil storage tank, second sealing area, and described oil storage tank is arranged between described first sealing area and the described second sealing area.
In preferred embodiment of the utility model, described oil storage tank bottom is provided with a plurality of holes.
The beneficial effects of the utility model are: the double-sealing device of the utility model oil cylinder, comprise: cylinder cap, seal arrangement, described cylinder cap place is provided with seal arrangement, described seal arrangement comprises first sealing area, oil storage tank, second sealing area, described oil storage tank is arranged between described first sealing area and the described second sealing area, can in situation about working long hours, can not cause dry friction yet, improve job schedule, and simple in structure.
