The multi-lip sealing ring comprises a ring body, two equally-spaced ring lips are arranged on the inner side of the ring body, and an O-shaped sealing ring mounting groove is formed in one side, away from the ring lips, of the ring body.
An O-shaped sealing ring is arranged in the mounting groove.
And a second limiting ring is arranged on one side, away from the second shell, of the second bearing.
Compared with the prior art, the utility model has the beneficial effects that: this kind of can utilize rotatory sealing washer of pressure differential compensation, when the wearing and tearing appear in the sealing washer of many lips, under the effect of many lips sealing washer body elasticity, many lips sealing washer is automatic to be embraced tightly with the rotation axis, on the other hand, each lip ring package tightly the rotation axis under the effect of high-pressure atmosphere end, and the inside vacuum is higher, and the package tightly the power is bigger to the whole sealed effect of many lips sealing washer has effectually been ensured. The rotary sealing ring is simple in structure and convenient to operate, and can automatically compensate when the multi-lip sealing ring is worn, so that the tightness of the rotary shaft is effectively ensured, and the use cost is reduced.
