Abstract
A sealing device of a diaphragm compressor compensation oil pump comprises an oil pump main shaft and a bearing seat used for supporting the main shaft. A groove is formed in the contact position of the bearing seat and the main shaft, a first sealing ring is arranged in the groove, and the sealing device further comprises a sealing hood fixed on the end face of the bearing seat. The main shaft penetrates through the center of the sealing hood, a groove is formed in the contact position of the sealing hood and the main shaft, a second sealing ring is arranged in the groove, an annular cavity is formed between the bearing seat and the sealing hood and filled with hydraulic oil, and a pressure increasing metal ring is fixedly connected to the part, located in the annular cavity, of the main shaft. Rotation of the oil pump main shaft is utilized to increase oil pressure in the annular cavity in a forced mode, and hydraulic oil in the oil pump can not leak.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of seal arrangement of diaphragm type compressor compensation oil pump.
Background technique
Membrane compressor is a kind of positive displacement compressor of special construction, has compression ratio large, good airproof performance, the feature that pressurized gas is not polluted by lubricant oil and other solid impurities.Therefore be applicable to compress high-purity, rare valuable, inflammable and explosive, poisonous and harmful, there is the gases such as corrosivity and high pressure, be widely used in the fields such as medical science, chemical industry.Existing diaphragm type compressor adopts oil pump feed, but the vibrations of and compressor itself large due to oil pressure cause the leakage of hydraulic oil, and compressor operating a period of time will servicing fluids force feed, and not only operation bothers, and has caused waste.
Model utility content
Goal of the invention of the present utility model is a kind of seal arrangement that can effectively place the diaphragm type compressor compensation oil pump of hydraulic oil leakage of design, and its concrete technological scheme is:
The seal arrangement of diaphragm type compressor compensation oil pump, comprise oil pump main shaft and for the bearing support of supports main shaft, bearing support and main shaft contacting point are provided with groove, in groove, be provided with the first seal ring, also comprise the seal closure that is fixed on bearing support end face, main shaft passes from seal closure center, seal closure and main shaft contacting part are provided with groove, in groove, be provided with the second seal ring, between bearing support and seal closure, form a circle ring chamber, in circle ring chamber, fill with hydraulic oil, in circle ring chamber internal spindle, be fixedly connected with a supercharging metal cirque.
Further, described the first seal ring and the second seal ring are copper eyelet.
Further, described seal closure and bearing support are bolted to connection.
Adopt technique scheme, can utilize the rotation of oil pump main shaft itself, forcing increases circle ring chamber internal oil pressure, has guaranteed that the hydraulic oil of oil pump inside can not revealed.
Accompanying drawing explanation
The seal arrangement schematic diagram of Fig. 1 diaphragm type compressor compensation oil pump.
Wherein, 1 bearing support, 2 seal closures, 3 circle ring chambers, 4 second seal rings, 5 main shafts, 6 supercharging metal cirques, 7 first seal rings.
Embodiment
The embodiment who sets forth below represents and allows those skilled in the art to put into practice necessary information of the present utility model, and illustrates and put into practice best mode of the present utility model.Once read with reference to the accompanying drawings following description, those skilled in the art just will understand design of the present utility model and will recognize the application of these designs of not illustrating especially herein.Should be appreciated that these designs and application fall into the scope of disclosure and the accompanying claims book.
Seal arrangement with reference to a kind of diaphragm type compressor compensation oil pump shown in accompanying drawing 1, comprise oil pump main shaft 5 and for the bearing support 1 of supports main shaft 5, bearing support 1 is provided with groove with main shaft 5 contacting points, in groove, be provided with the first seal ring 7, also comprise the seal closure 2 that is bolted on bearing support 1 end face, main shaft 5 passes from seal closure 2 centers, seal closure 2 is provided with groove with main shaft 5 contacting parts, in groove, be provided with the second seal ring 4, between bearing support 1 and seal closure 2, form a circle ring chamber 3, in circle ring chamber 3, fill with hydraulic oil, in circle ring chamber 3 internal spindle 5, be fixedly connected with a supercharging metal cirque 6, supercharging metal cirque 6 can produce pressure to hydraulic oil in High Rotation Speed process, the hydraulic oil of oil pump inside can not leaked, the first seal ring 7 and the second seal ring 4 are copper eyelet, there is certain elasticity and suppleness, the effect of having played sealing can not damage main shaft 5 again.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all mode of executions.And these belong to apparent variation that spirit of the present utility model extended out or change still among protection domain of the present utility model.
