Abstract
The utility model provides a sealing element for a water pump. The sealing element for the water pump comprises a fastening ring which is fixed through a socket head cap screw. A groove at the upper end of a stationary seal ring seat is provided with a first stationary seal ring, and the groove at the lower end of the stationary seal ring seat is provided with a second stationary seal ring which is arranged on a ladder-shaped step of the stationary seal ring seat. A rotary seal ring and a first rotary seal ring are arranged in the groove of the rotary seal ring seat. A spring seat is arranged on the right side of the rotary seal ring. A spring is arranged at the lower end of the spring seat. A second rotary seal ring is arranged in the groove of a transmission sleeve. According to the design of the sealing element for the water pump, stationary seal rings and the rotary seal ring and a seal sleeve cylinder are integrally formed, the design of the prior art that components are installed on the sealing element one by one is changed, occurrence of error is reduced, when the sealing element for the water pump is adjusted, only a center shaft of the water pump need adjusting, and therefore accuracy of installation can be effectively improved. The sealing element for the water pump is reliable in seal, long in service life, and wide in application range.
Description
Technical field
The utility model relates to the mechanical seal device of machinery, particularly a kind of Sealing for water pump.
Background technique
Water pump often can occur that water pump spindle bolster bearing chamber wearing and tearing, bearing position wearing and tearing, pump housing crackle are broken, cavitation of pump, erosive wear etc. in During Process of Long-term Operation.After the problems referred to above occurring, enterprise's tradition solution is machining reparation after repair welding or the brush plating, but all there is certain drawback in both, and the thermal stress that repair welding high temperature produces can't be eliminated fully, easily causes Material damage, causes parts to occur crooked or fracture; And Brush Plating is limited by coating thickness, peel off easily, and above two kinds of methods all is to use the metallic prosthetic metal, can't change the matching relationship of " firmly to hard ", under each power comprehensive function, still can cause again wearing and tearing.Contemporary western countries is used the restorative procedure of polymer composite for above problem more, and uses the more Mei Jiahua technical products that has, and it has superpower cohesion, the excellent combination properties such as compressive strength.The application macromolecular material is repaired, and can exempt from dismounting and exempt from machining.Both of no help welding heat stress influences; it is also unrestricted to repair thickness; the deformability that the metallic material that the while product has does not possess; but the impact endurance test shock of absorption equipment; avoid the possibility of again wearing and tearing; and working life of extension device parts greatly, for enterprise saves a large amount of dead times, create huge economic value.
The Sealing quality requirement of nowadays water pump being installed is more and more higher, second-rate Sealing makes and has been subject to restriction the working life of water pump, movement parts wearing and tearing to Sealing in rotatablely moving are results of factors combination, so improve seal ring wear-resistant outside, sealability with and between connect combination quality also affect the using effect of Sealing, seal ring, these component such as spring seat are as the water pump installation accessories, in the process of installing, because the difference of personnel's experience, can produce different installation effects, thereby cause mechanical wear large, affected working life.
The model utility content
For addressing the above problem, the utility model discloses a kind of Sealing for water pump, dynamic and static ring and seal sleeve are formed one, change and part component were contained on the Sealing in the past, reduce the generation of error, only need adjust the axis of pump during adjustment, like this validity of energy Effective Raise installation.
The utility model provides a kind of Sealing for water pump, comprise fastening ring, described fastening ring is fixed by socket head screw, stationary seat upper end groove arranges static sealing ring one, and the lower end groove arranges static sealing ring two, and described static sealing ring two is arranged on the terraced steps of stationary ring, rotating ring and dynamic seal ring one are set in the groove of rotating seat, described rotating seat right side arranges spring seat, and the spring seat lower end arranges spring, and dynamic seal ring two is set in the groove of drive sleeve.The disclosed a kind of Sealing for water pump of the utility model, dynamic and static ring and seal sleeve are formed one, change and part component were contained on the Sealing in the past, reduce the generation of error, only need adjust the axis of pump during adjustment, the validity of like this can Effective Raise installing, the utility model sealing is reliable, long service life, applied widely.
A kind of improvement of the disclosed a kind of Sealing for water pump of the utility model, described stationary seat lower end arranges pad.This improvement effectively prevents the leakage of medium by the setting of pad, thereby effectively avoids the error that produces in the installation process, the useful energy height working life of Sealing.
A kind of improvement of the disclosed a kind of Sealing for water pump of the utility model, described drive sleeve is stepped shaft.This improvement has not only reduced the physical dimension of whole sealing machine, and can also be reduced to this, can also reduce wearing and tearing.
A kind of improvement of the disclosed a kind of Sealing for water pump of the utility model, rotating ring and stationary ring are close to by spring.This improvement is connected with stationary ring by rotating ring and is connected, can reach the validity when installing, only need adjust and drive sleeve during adjustment, just can coordinate the alignment error between each assembly parts, thereby effectively avoid the error that produces in the installation process, the useful energy height working life of Sealing.
The disclosed a kind of Sealing for water pump of the utility model, dynamic and static ring and seal sleeve are formed one, change and part component were contained on the Sealing in the past, reduce the generation of error, only need adjust the axis of pump during adjustment, the validity of like this can Effective Raise installing, the utility model sealing is reliable, long service life, applied widely.
