Abstract
The utility model relates to a novel seal structure of N-type pump bracket oil chamber, including a shaft, a pump body, a bearing, a bearing pressure cover and an oil chamber, which is characterized in that a dustproof plate is fixed and connected on the shaft by bolts. A labyrinth seal is arranged between the dustproof plate and the bearing pressure cover, which consists of a circular groove on the axial inner wall of the bearing pressure cover and the outer circular surface of the dustproof plate. The axial inner wall of the bearing pressure cover has more than two circular grooves, and is combined through clearance with the outer circular surface of the dustproof plate. The utility model has the following advantages: 1) good seal; 2) generally, not requiring any maintenance; 3) without friction, low power consumption and long life time; 4) realizing the effective seal function of the N-type pump bracket oil chamber in the combination of simple parts.
Description
Technical field
The utility model relates to a kind of N type condensate extractionpump, the novel sealing structure of particularly a kind of N type pump bracket grease chamber.
Background technique
What the carriage grease chamber of N type pump adopted at present is the felt collar oil sealing, for the ease of the bearing in the carriage is lubricated, make bearing can carry out proper functioning, grease chamber's structure is arranged in the carriage, the inside has poured into an amount of lubricant oil, at any time bearing is lubricated, the felt collar oil seal structure is exactly that the oil in the carriage is sealed in this effect, but in the using process of reality, find following problem: because the long-time friction of felt collar and pump shaft, the wearing and tearing of felt collar have been caused, thereby the gap that makes felt collar and pump shaft becomes big, makes oil leakage quantity very big, and felt collar does not just have the effect of sealing, also working environment has on every side been caused pollution simultaneously, and the working life of felt collar is very short, need often go to change, and has influenced the normal use of pump group.
Summary of the invention
The purpose of this utility model is that the felt collar oil sealing that solves N type pump bracket grease chamber in the prior art wearing and tearing takes place and causes the problem of oil leak, provide a kind of Maintenance free, with the novel sealing structure of axle frictionless N type pump bracket grease chamber.The utility model designs the novel sealing structure of a kind of N type pump bracket grease chamber, comprises axle, the pump housing, bearing, bearing gland, grease chamber, it is characterized in that: be connected with dustproof dish by screw on axle, between dustproof dish and the bearing gland labyrinth seal arranged.Labyrinth seal is made of ring groove on the axial inwall on the bearing gland and dustproof dish periphery.Ring groove number on the axial inwall on the bearing gland is more than two.Between axial inwall on the bearing gland and the dustproof dish periphery is Spielpassung.Advantage of the present utility model is: 1. good airproof performance; 2. generally do not need to safeguard; 3. do not have friction, power consumption is little, long service life; 4. realize effective sealing function of N type pump bracket grease chamber with the combination of simple part.

Embodiment
Comprise axle 1, the pump housing 2, bearing 3, bearing gland 4, grease chamber 5 among the figure, it is characterized in that: on axle 1, be fixedly connected with dustproof dish 7, between dustproof dish 7 and the bearing gland 4 labyrinth seal arranged by screw 6.Labyrinth seal is made of ring groove on the axial inwall on the bearing gland 48 and dustproof dish 7 peripheries 9.Ring groove 8 numbers on the axial inwall on the bearing gland 4 are more than two, are Spielpassung between axial inwall on the bearing gland 4 and dustproof dish 7 peripheries 9.In use, after pump starts, rotation along with axle 1, dustproof dish 7 is with axle 1 rotation of pump, because the factor of structure, can the formation labyrinth between the ring groove 8 of the periphery 9 of dustproof dish 7 and bearing gland 4, increase the resistance in the leakage flow, pressure reduction all disappears when the leakage way two ends, can realize that the lubricant oil in the grease chamber 5 does not leak.
Claims (4)
