Description
Technical Field
The utility model relates to a sealing member technical field especially relates to a semi-enclosed water pump sealing member.
Background
The water pump is a machine for conveying liquid or pressurizing liquid, and it can transfer the mechanical energy of prime mover or other external energy to the liquid to increase the energy of liquid, and is mainly used for conveying liquid including water, oil, acid-base liquid, emulsion, suspoemulsion, liquid metal, etc., and can also convey liquid, gas mixture and liquid containing suspended solid matter. The technical parameters of the water pump performance include flow, suction lift, shaft power, water power, efficiency and the like, and the water pump can be divided into a volumetric water pump, a vane pump and the like according to different working principles. The displacement pump transfers energy by utilizing the change of the volume of a working chamber; vane pumps transfer energy by the interaction of rotating vanes with water and are available in the types of centrifugal pumps, axial flow pumps, mixed flow pumps, and the like. At present, the quality requirement of a sealing element for installing the water pump is higher and higher, the sealing element with poor quality causes large mechanical abrasion of the water pump, and the service life is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned defects, the present invention provides a semi-enclosed water pump sealing member with simple structure and convenient use.
In order to achieve the above object, the utility model discloses a following technical scheme realizes: semi-enclosed water pump seal spare, including quiet ring, rotating ring, quiet ring seat, rotating ring seat, quiet ring seat upper end recess is equipped with rubber seal I, quiet ring seat connects out with quiet ring and is equipped with rubber seal II, the outside and the axial terminal surface of quiet ring seat are equipped with big envelope I, be equipped with trapezoidal recess in the rotating ring, trapezoidal recess is embedded to have rubber seal III, the rotating ring right side is equipped with the rotating ring seat, be equipped with the recess in the rotating ring seat, the rotating ring is pegged graft in the recess along axial sliding, be equipped with spring, spring washer in the recess, rotating ring seat are fastened by II connections of big envelope.
The sleeve I and the sleeve II are made of rubber, and the outer edge of the sleeve I is provided with a sealing ring which is arranged in a protruding mode along the radial direction.
And a cushion pad is arranged at the joint of the spring washer and the movable ring seat.
The utility model has the advantages that: the rubber sealing sleeve can effectively reduce the rigid contact between the static ring seat and the pump body and the rigid contact between the dynamic ring seat and the pump body, reduce the abrasion and prolong the service life of the static ring seat and the dynamic ring seat. The spring is pressed between the movable ring and the movable ring seat, so that direct contact between a water body and the spring is avoided, and the service life of the spring is prolonged.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, semi-enclosed water pump sealing member, including quiet ring 1, rotating ring 2, quiet ring seat 3, rotating ring seat 4, the recess of 3 upper ends of quiet ring seat is equipped with rubber seal I5, quiet ring seat 3 connects out with quiet ring 1 and is equipped with rubber seal II 6, the outside and the axial terminal surface of quiet ring seat 3 are equipped with big envelope I7, be equipped with trapezoidal recess in the rotating ring 2, trapezoidal recess is embedded to have rubber seal III 8, 2 right sides of rotating ring are equipped with rotating ring seat 4, be equipped with the recess in the rotating ring seat 4, rotating ring 2 pegs graft in the recess along axial sliding, be equipped with spring 9 in the recess, spring packing ring 10, rotating ring 2, rotating ring seat 4 is connected by big envelope II 11 and is fastened.
The sleeve I7 and the sleeve II 11 are made of rubber, and the outer edge of the sleeve I7 is provided with a sealing ring which is arranged in a protruding mode along the radial direction. A buffer cushion 12 is arranged at the joint of the spring washer 10 and the movable ring seat 4.
The utility model discloses simple structure, use are convenient. The rubber sealing sleeve can effectively reduce the rigid contact between the static ring seat and the pump body and the rigid contact between the dynamic ring seat and the pump body, reduce the abrasion and prolong the service life of the static ring seat and the dynamic ring seat. The spring is pressed between the movable ring and the movable ring seat, so that direct contact between a water body and the spring is avoided, and the service life of the spring is prolonged.
