Abstract
The utility model discloses a novel fan bearing seat prevention leakage oil structure, including centrifugal fan, bearing frame, there is the negative pressure pipe at centrifugal fan negative pressure inlet connection, the other end of negative pressure pipe is connected on the bleeder vent of bearing frame, is connected with ball valve, negative pressure table on the negative pressure pipe. The utility model discloses a set up negative pressure pipe, ball valve etc. The negative pressure of utilizing fan work to produce prevents the bearing frame oil leak, simple structure, and the prevention of seepage is effectual.
Description
Technical field
This utility model is specifically related to a kind of novel fan bearing block antiseepage structure for oil.
Background technology
At present, the centrifugal blower of cleaner unit is usually and is made up of dynamical system, fan blade, shaft coupling and fan shaft, its apoplexy
Machine is mounted on an axle and is supported by bearing and stand, and bearing block is made up of upper and lower two parts, and stand end face has packing groove, relies on pressure
Ring compression sealing.Because of axle rotation and packing phase mutual friction, bearing block permeability after time length, can be caused.
Content of the invention
The deficiency existing for above-mentioned prior art, this utility model provides a kind of more rational blower fan of structure design
Bearing block antiseepage structure for oil.
The technical solution of the utility model: novel fan bearing block antiseepage structure for oil, including centrifugal blower, bearing block, its
It is characterised by, be connected with negative tube in centrifugal blower negative pressure entrance point, the other end of negative tube is connected to the air-vent of bearing block
On, negative tube is connected with ball valve, vacuum table.
Compared to existing technologies, advantage of the present utility model: by arranging negative tube, ball valve etc., using blower fan work
Preventing bearing block oil leak, structure is simple, good seepage-proof property for the negative pressure producing.
Brief description
Fig. 1 is structural representation of the present utility model
Wherein, 1, centrifugal blower, 2, bearing block, 3, negative tube, 4, ball valve, 5, vacuum table.
Specific embodiment
In conjunction with accompanying drawing, this utility model is further elaborated.
As shown in figure 1, novel fan bearing block antiseepage structure for oil, including centrifugal blower 1, bearing block 2, in centrifugal blower 1
Negative pressure entrance point is connected with negative tube 3, and the other end of negative tube 3 is connected on the air-vent of bearing block 2, and negative tube 3 connects
There are ball valve 4, vacuum table 5.
Centrifugal blower 1 start after produce negative pressure, open the ball valve 4 on negative tube 3, then as needed many Wind Volumes and protect
Card lubricating oil does not exosmose to determine the opening degree of ball valve 4.
