The utility model content
Technical problem to be solved in the utility model is: provide a kind of and prevent that external liquid from entering fuel tank and can reclaim the sealing device of transmission mechanism in the horizontal centrifuge of less amount of lubrication oil.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the sealing device of transmission mechanism in the horizontal centrifuge, comprise: be arranged on the bearing block on the frame, be arranged on bearing and the gland that is arranged on the bearing outside in the bearing block, be provided with oil-recovery tank in the bearing block, be equipped with main shaft in the bearing, main shaft passes from gland, be provided with sealing shroud between described gland and the main shaft, the inboard of sealing shroud is provided with main baffle ring, the inwall of gland is provided with leakproof ring and at least two secondary baffle rings, the leakproof ring is positioned at outermost, between main baffle ring and the gland, be provided with the gap between leakproof ring and secondary baffle ring and the sealing shroud, form the retaining liquid bath between leakproof ring and the secondary baffle ring that is adjacent, the retaining liquid bath communicates with the liquid return trough that is opened in the gland outside, form the retaining oil groove between the adjacent in twos secondary baffle ring, the retaining oil groove communicates with oil-recovery tank by the drainback passage that is opened in the gland inboard.
Offer conical cavity on the inner surface of described main baffle ring.
The bottom of the bottom of described retaining oil groove and retaining liquid bath is that the outer surfaces of sealing shroud is provided with the zigzag ripple.
The beneficial effects of the utility model are: owing to be furnished with leakproof ring and a plurality of secondary baffle ring on the gland in the utility model, sealing shroud is provided with main baffle ring, make a spot of lubricating oil by the retaining oil groove between the secondary baffle ring in overpressure cap the return flow line and the backflash in the bearing block be back in the fuel tank, and external liquid is discharged by the liquid return trough of retaining liquid bath in overpressure cap between leakproof ring and the secondary baffle ring; In addition, the zigzag ripple of conical cavity and retaining oil groove bottom and retaining liquid bath bottom has improved occlusion effect in the main baffle ring.Like this, just guaranteed that the lubricating oil in the fuel tank can not mix external liquid, thereby guaranteed lubricant effect, make centrifuge can be because of the lubricated bad damage that causes centrifuge, shut down and stop production, not have influence on the ordinary production of centrifuge.
