Abstract
A water pump shaft seal end cover is characterized in that the end cover is provided with a fixed hole, and consists of an upper semicircular ring and a lower semicircular ring which are split, wherein the upper semicircular ring and the lower semicircular ring are respectively provided with a pressing protruded ring, the pressing protruded ring extends along the axial direction of the inner cavity wall of the upper semicircular ring and the lower semicircular ring, two pairs of fixed lug plates are arranged on the upper semicircular ring and the lower semicircular ring, and the fixed lug plate is provided with a connecting hole. The utility model has reasonable design and simple structure, is convenient to install and maintain, can be replaced without removing the motor and the water pump, has good seal effect, and can greatly lighten the labor intensity of the maintainers.
Description
Technical field
The utility model relates to a kind of rotation shaft seal, particularly a kind of water pump spindle end cover.
Background technique
The mode that the shaft sealer of the water pump that present domestic various places are used adopts packing matcrial, end cap to compress mostly, end cap series cast steel one-time-concreting is finished, when the leakage from water pump amount strengthens, need the fit sealing end cap, increase its decrement to sealing material, often occur in fastening process because dynamics is held situation not enough so that the end cover fracture, and changing end cover needs motor and water pump complete removal, workload is big and influence generator and normally move.
The model utility content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of water pump spindle end cover of dismantling and changing be convenient to is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of water pump spindle end cover has fixed hole on end cap, described end cap is made up of first annulus 1 and second annulus 2 of splitting.
As the further improved technological scheme of the utility model, on first annulus 1 and second annulus 2, be equipped with and compress prominent ring 3, this compresses prominent ring 3 extending axially along first annulus 1 and second annulus 2 internal chamber walls.
As the further improved technological scheme of the utility model, on first annulus 1 and second annulus 2, respectively be provided with a pair of fixedly otic placode 4, have attachment hole 5 on the described fixedly otic placode.
As the further improved technological scheme of the utility model, fixed hole is two, is separately positioned on first annulus 1 and second annulus 2.
The utility model water pump spindle sealing cover adopts the split structure, connects with bolt between two lobes.Therefore the utility model is reasonable in design, simple in structure, install and maintenance convenient, motor and water pump complete removal can be changed end cover, and good sealing effect, can alleviate maintainer's labor intensity greatly.Disperseed because of the split end cap is stressed simultaneously, easy-rupturing has not been simplified technology, has saved manpower and materials.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Referring to Fig. 1 and Fig. 2, the water pump spindle end cover is made up of first annulus 2 and second annulus 3 of splitting, have two on the end cap and be used for fixed hole that end cap is connected with pump body, on first annulus 1 and second annulus 2, be equipped with and compress prominent ring 3, this compresses prominent ring 3 extending axially along first annulus 1 and second annulus 2 internal chamber walls, a described side that compresses prominent ring 3 towards close water pump, water pump spindle passes and compressing prominent ring 3, compresses prominent ring 3 and compresses seal ring; Bolt is fixed on the water pump spindle end cover on the water pump by fixed hole; Respectively be provided with a pair of fixedly otic placode 4 on first annulus 1 and second annulus 2, have attachment hole 5 on the described fixedly otic placode 4, bolt is fixed together first annulus 1 and second annulus 2 by attachment hole 5.
