Abstract
The invention provides a two-stage conical surface-end surface series contact type mechanical sealing device for a sewage pump, and belongs to the technical field of liquid mechanical sealing devices.The two-stage conical surface-end surface series contact type mechanical sealing device comprises a rotating shaft, wherein a shaft sleeve is arranged on the outer side of the rotating shaft in a sleeving mode, a main sealing assembly body and a secondary sealing assembly body are arranged on the outer side of the shaft sleeve in a series connection and sleeving mode, and a main sealing side gland and a secondary sealing side gland are correspondingly arranged on the outer sides of the main sealing assembly body and the secondary sealing assembly body correspondingly; and a sealing device fixing body is arranged on one side of the main sealing side gland, the other side of the main sealing side gland is matched with the secondary sealing side gland, and the main sealing side gland, the sealing device fixing body and the sealing side gland are connected and fixed to form a whole. According to the two-stage conical surface-end surface series contact type mechanical sealing device, a main sealing movable ring and a main sealing static ring are in conical surface sealing fit, so that the adhesion wear degree of suspended solid particles in a medium is reduced; and in addition, a secondary sealing push ring and a secondary sealing static ring are in end surface sealing fit, so that series two-stage sealing is formed, the leakage amount is effectively reduced, and the sealing safetyand stability are improved.
