Abstract
The utility model relates to the lubricating oil sealing technology field, specifically to a pneumatic sealing oil baffle for a bearing housing. The pneumatic sealing oil baffle is connected with a bearing housing via a negative pressure pipe. The pneumatic sealing oil baffle is characterized by comprising a negative pressure unit and an oil separator which are connected via the negative pressure pipe. The pneumatic sealing oil baffle is simple in structure and low in manufacture cost and is convenient to use. In addition, the pneumatic sealing oil baffle achieves good effect of oil sealing of a bearing housing and realizes installation with no downtime.
Description
Technical field:
The utility model relates to the seal oil technical field, relates in particular to a kind of bearing housing pneumatic seal oil catch.
Background technique:
Bearing housing ubiquity oil seepage problem in the work causes oil level unstable, and the bearing oil starvation damages, the stuffing box bearing wearing and tearing, and lubrication oil consumption is big, and influence is carried out production strictly in line with rules and regulations.Traditional shaft end seal generally adds felt collar by cast steel or adopts structures such as copper gear piece, aluminium matter gear piece, and its gap changes or the aging sealability instability that makes of felt collar.
The model utility content:
The utility model technical problem to be solved is to provide a kind of bearing housing pneumatic seal oil catch, can effectively solve the bearing box oil leakage problem.
The utility model technical problem to be solved adopts following technological scheme to realize,
A kind of bearing housing pneumatic seal oil catch is connected with bearing housing through the negative pressure pipe, it is characterized in that: comprise negative pressure device, oil separator, be connected through the negative pressure pipe between negative pressure device and the oil separator.
Said negative pressure device is a blower fan.
Outside bearing housing, set up negative pressure device (blower fan) to form negative pressure; Install oil separator again, make operating bearing housing axle head produce the negative pressure of 30～50m1 water column, the mist of oil in the bearing housing is attracted to the oil separator place along the negative pressure pipe; Form oil stream through oil separator; Under action of gravity, flow back to bearing housing again, back and forth operation.The negative pressure that forms at the bearing housing axle head can not be pulled away the oil in the bearing housing along pipe, also can not flow out by direct-axis, reaches sealing effect.
Said oil separator is metal cylinder, and upper and lower end is communicated with negative pressure pipe, built-in steel wire and metal wool.When the mist of oil in the bearing housing was flowed through oil separator along the negative pressure pipe, because of the caliber chap, it is big that volume becomes, and flow velocity diminishes, and under the effect of steel wire and metal wool, oil is separated, and forms oil stream in the oil separator thereby be trapped in, and under action of gravity, flows back to bearing housing.
Simple in structure, the low cost of manufacture of the utility model, easy to use, and also effective to the oil sealing of bearing housing, and can realize not shutting down installation.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with specific embodiment and diagram, further set forth the utility model.
As shown in Figure 1, a kind of bearing housing pneumatic seal oil catch is connected with bearing housing 4 through negative pressure pipe 2, comprises negative pressure device 1, oil separator 3, is connected through negative pressure pipe 2 between negative pressure device 1 and the oil separator 3.
Outside bearing housing 4, set up negative pressure device 1 to form negative pressure; Install oil separator 3 again, make operating bearing housing axle head 5 produce the negative pressure of 30～50ml water column, the mist of oil in the bearing housing 4 is attracted to oil separator 3 places along negative pressure pipe 2; Form oil stream through oil separator 3; Under action of gravity, flow back to bearing housing 4 again, back and forth operation.The negative pressure that forms at bearing housing axle head 5 can not be pulled away the oil in the bearing housing 4 along pipe, also can not flow out by direct-axis, reaches sealing effect.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (2)
1. a bearing housing pneumatic seal oil catch is connected with bearing housing through the negative pressure pipe, it is characterized in that: comprise negative pressure device, oil separator, be connected through the negative pressure pipe between negative pressure device and the oil separator.
