Abstract
The utility model relates to a pump shaft packaging type mechanical seal device of a single-stage single-suction centrifugal pump. A shaft sleeve is sleeved on a pump shaft. A springs seat, a spring, a moving ring, a stationary ring, a sealing ring, a mechanical seal press cover, a locating ring and a tightening ring are arranged on the shaft sleeve in sequence in a penetrating mode. The sealing ring and the stationary ring are fixed inside the mechanical seal press cover. Adjacent abrasion faces of the moving ring and the stationary ring are abutted. The locating ring is arranged on a fixing ring in a rotary mode. The tightening ring and the shaft sleeve are fixed on the pump shaft through screws. The spring seat is fixed on the shaft sleeve through a screw. The mechanical seal press cover is fixedly connected with the stationary ring through an anti-rotating pin. Two ends of the spring are respectively abutted against the spring seat and the moving ring. The pump shaft packaging type mechanical seal device of the single-stage single-suction centrifugal pump has the advantages that sealing reliability of the pump shaft is high, service life is greatly prolonged, and work efficiency is improved, and is used as a shaft seal device by a single-stage single-suction centrifugal pump which needs no leakage.
Description
Technical field
The utility model relates to a kind of pump shaft integrated mechanical sealing device of single stage single suction volute pump.
Background technique
In petroleum refining, petroleum production, chemical industry, generating, metallurgy, space flight, pharmacy, field of papermaking, the customer requirements field of employment is clean, does not allow to use the single stage single suction volute pump of leakage; The shaft seal mode of the mechanical seal of the single stage single suction volute pump that uses at present; exist decrement and the cleaning degree of machine envelope to grant assurance, stationary ring often can occur and damage phenomenon, equipment failure is more; leakage phenomenon is more serious, can't reach the user to the requirement of the clean cleaning of environment.
Summary of the invention
The utility model is realized with following mode.
The pump shaft integrated mechanical sealing device of single stage single suction volute pump, axle sleeve is sleeved on the pump shaft, spring seat, spring, rotating ring, stationary ring, seal ring, machine sealed cover, positioning ring, retaining ring are installed on the axle sleeve successively, seal ring, stationary ring are fixed in the machine sealed cover, the adjacent flour milling of rotating ring and stationary ring near, the positioning ring spinning is fixed on the retaining ring, retaining ring and axle sleeve are fixed on the pump shaft through screw, spring seat is fixed on the axle sleeve through screw, the machine sealed cover is through the affixed stationary ring of stop pin, and both ends of the spring leans respectively spring seat and rotating ring.
The utility model adopts integrated mechanical sealing between pump cover and pump shaft, the sealing reliability height of pump shaft, long service life, raising work efficiency; Without leakage phenomenon, the field of employment was clean when centrifugal pump used; The single stage single suction volute pump that is suitable for petroleum refining, petroleum production, chemical industry, generating, metallurgy, space flight, pharmacy, field of papermaking use is used as gland seal device.
