Description

Suspension with bearing support

Technical Field

The utility model relates to a pump valve technical field, concretely relates to suspension that tape spool held.

Background

The fluoroplastic lined chemical centrifugal pump is designed and produced according to international standard and combined with the processing technology of a non-metal pump. The pump body of the existing fluoroplastic-lined chemical centrifugal pump adopts a metal shell with a lining of fluorinated ethylene propylene (F46), the pump cover, the impeller and the shaft sleeve are integrally sintered and pressed and formed by wrapping fluoroplastics outside a metal insert, the shaft seal adopts a tetrafluoro filling material, and an inlet and an outlet are reinforced by cast steel bodies.

Centrifugal pumps operate by causing water to move centrifugally as a result of the rotation of an impeller. Before the water pump is started, the pump shell and the water suction pipe are filled with water, then the motor is started, the pump shaft drives the impeller and the water to rotate at a high speed, the water is thrown to the outer edge of the impeller to be thrown into a water pressure pipeline of the water pump through a flow channel of the volute-shaped pump shell.

The pump shaft in the existing fluoroplastic pump can have radial and axial runout after long-term use, and is poor in stability, so that the service life of the fluoroplastic pump is short, and the actual working requirement cannot be met.

SUMMERY OF THE UTILITY MODEL

To the above problem, the present invention is directed to a suspension with a bearing support.

In order to realize the technical purpose, the utility model discloses a scheme is:

preferably, the suspension with the bearing support comprises a pump shaft and a pump body, and is characterized in that: the right end of the pump body is connected with a suspension through a bolt, the left end of the suspension is connected with a pump cover through a bolt, the right end of the pump cover is fixed with a static ring gland through a screw, and an outer mechanical seal is arranged between the pump cover and the static ring gland; the right end face of the interior of the suspension is connected with a bearing gland through a screw, a bearing is arranged in the bearing gland, and an oil seal is arranged between the inner end of the suspension and the pump shaft.

Preferably, the outer machine seal comprises a static ring, a movable ring grinding head, a tetrafluoro bellows, a movable ring seat, a spring seat and a clamp, wherein the movable ring grinding head, the movable ring seat, the spring seat and the clamp are sequentially arranged on an outer ring of the tetrafluoro bellows from left to right, the spring is arranged between the movable ring seat and the spring seat, and the static ring is arranged at the left end of the movable ring grinding head.

Preferably, a yellow oil cavity is arranged between the bearing and the oil seal.

Preferably, the outer cover machine seal is of an outer cover single end face balanced type.

Preferably, the oil seal is made of nitrile rubber.

The beneficial effects of the utility model are that the bearing is adopted in the suspension frame, the service life of the fluoroplastic pump is prolonged, and meanwhile, the bearing prevents the pump shaft from jumping in the radial direction and the axial direction, thereby increasing the stability; the external single-end-face balanced mechanical seal is adopted, can be automatically adjusted and self-lubricated, does not need an external cooling water to cool the mechanical seal, and is suitable for cleaning media.
