In the water seal of above-mentioned suction booster, convex body and described convex body that a side of described stationary ring has protrusion are resisted against on the sidewall of described rotating ring.The convex body of one side of stationary ring is resisted against on the sidewall of rotating ring, can form sealing, has good sealing effect.
In the water seal of above-mentioned suction booster, the L-shaped and described spring in the cross section of described collar is resisted against on the sidewall of described collar.Collar is L-shaped, and collar can better must be located with spring.
Compared with prior art, the water seal of this suction booster has the following advantages:
1, between the base one of the water seal of this suction booster and base two, be provided with stationary ring and rotating ring one, between rotating ring one and base two, be provided with bellows, therefore the structure of the water seal of this suction booster is comparatively complicated, makes to form between the pump housing of suction booster and main shaft multiple-sealed, has good sealing effect;
During 2, by spring, collar is resisted against respectively corresponding annular groove inwall, has good supporting effect, prevents bellows distortion;
3, rotating ring two is L-shaped, on base one, has kink, and rotating ring two abuts on kink, can form good sealing effect.
