Abstract
The utility model relates to a mechanical seal, in particular to a mechanical sealing element for a domestic pump,which is deisgned for solving the technical problems of larger volume and poor structure in a similar product.The mechanical sealing piece comprises a seal end plate, a L-shaped rubber gasket, a stationary seal ring, a rotating seal ring, a rubber corrugated pipe, a shaft sleeve, a spring and a spring gasket, wherein the stationary seal ring is in close contact with the rotating seal ring; the rubber corrugated pipe is arranged between the rotating seal ring and the shaft sleeve; and the spring is arranged between the shaft sleeve and the spring gasket. The utility model adopts the design points that the L-shaped rubber gasket is arranged between the seal end plate gland and the stationary seal ring; the rubber corrugated pipe, the shaft sleeve and the rotating ring are in interference fit; and the conic spring is arranged between the shaft sleeve and the spring gasket. The utility model has the advantages of more reasonable structure and small volume, and is suitable for improving structures of similar mechanical sealing pieces.
Description
Technical field
The utility model relates to mechanical seal, is a kind of family expenses pump mechanical sealing spare.
Background technique
Household series equipment such as home pipeline pump, bathroom recycle pump, family expenses washing machine.Along with the progress of science and technology, the raising that people require equipment; Make the big problem of original device body more outstanding.Patent No. ZL200720106246.2 as the Chinese patent literature publication, January 30 2008 notice of authorization day, the model utility name is called " universal machine Sealing ", this mechanical sealing element comprises that elastic support that is fastenedly connected by rotating ring, with rotating ring one end face and the helical spring that is wrapped in the elastic support periphery form moving ring assembly, form static components by stationary ring and its peripheral stationary ring cover, the inner ring surface that it is characterized in that elastic support is an indent annular corrugated pipe face, the middle axial plane fluid-tight engagement of the extended surface of bellows face and pump; Stationary ring overlaps establishes the prominent bar that is parallel to each other on the peripheral axial plane.Adopting bellows and extended surface thereof to make sealing surface can be according to the difference of setting height(from bottom), the setting height(from bottom) of regulating bellows satisfies the various pump class installation requirements of same diameter different heights, do not influencing under other universal component situation, select the elastic support different size to carry out wildcard, reach extensive general purpose.The seal ring of dynamic and static ring assembly can be selected the use that matches of the anticorrosive or anti abrasive seal ring of corresponding acid resistant alkali according to institute's Environmental Conditions.
The deficiency of above-mentioned patent is that volume is bigger, is further improved in configuration aspects.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of family expenses pump mechanical sealing spare to related domain, makes it solve that existing like product volume is big, the technical problem of poor structure.Its objective is and be achieved through the following technical solutions.
A kind of family expenses pump mechanical sealing spare, this mechanical sealing element comprises seal end plate, rubber L pad, stationary ring, rotating ring, rubber corrugated pipe, axle sleeve, spring, compression spring, wherein stationary ring closely contacts with rotating ring, be provided with rubber corrugated pipe between rotating ring and the axle sleeve, be provided with spring between axle sleeve and the compression spring.Its main points are to be provided with rubber L pad between described seal end plate and the stationary ring, and this pad plays the effect of oil sealing, prevent outwards leakage of oil.Described rubber corrugated pipe and axle sleeve, rotating ring are interference fit, and drive axle sleeve and rotating ring rotate together when making the pump shaft rotation.Be provided with volute spring between described axle sleeve and the spring pad, volute spring promotes rotating ring and closely contacts with stationary ring, and volute spring makes this family expenses pump mechanical sealing spare axial length shorten, and has promptly dwindled the volume of this mechanical sealing element.
Described volute spring one end is limited in the compression spring, and the other end and axle sleeve offset, and makes volute spring more even to the power of axle sleeve, guarantees closely contact between stationary ring and the rotating ring, produces effectively to seal.
Be provided with fastening piece between described axle sleeve and the rubber corrugated pipe, fastening piece is used for fixing rubber corrugated pipe on pump shaft, simultaneously axle sleeve is played positioning action.
The utility model structure is comparatively reasonable, and volume is little, is suitable as the architecture advances of similar machines Sealing.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model.
Above figure number and title: 1, seal end plate, 2, rubber L pad, 3, stationary ring, 4, rotating ring, 5, rubber corrugated pipe, 6, axle sleeve, 7, fastening piece, 8, spring, 9, compression spring.
Embodiment
Now in conjunction with the accompanying drawings, structure of the present utility model and principle are further described.
The main sealing configuration of this family expenses pump mechanical sealing spare promptly seals by closely contact generation between rotating ring 4 and the stationary ring 3, contacting by rotating ring being applied an end thrust between rotating ring and the stationary ring realizes, this thrust then is to be provided by volute spring 8, adopt volute spring herein, its advantage is that the axial length of volute spring is shorter, and volute spring is difficult for self bending, just makes the axial length of this family expenses pump mechanical sealing spare dwindle thus, uses convenient.One end and the compression spring 9 of volute spring offset, and in spacing and the compression spring, the other end and axle sleeve 6 offset, and compression spring is comparatively even to the power of axle sleeve to the spacing volute spring that makes of volute spring, its finally make between rotating ring and the stationary ring contact more tight reliable.Interference fit rubber corrugated pipe 5 between rotating ring and the axle sleeve, rubber corrugated pipe has not only played the effect of seal ring, simultaneously axle sleeve is had positioning action, is provided with fastening piece 7 between axle sleeve and the rubber corrugated pipe, the first is located axle sleeve, its two be fixedly rubber corrugated pipe on pump shaft.Be provided with rubber L pad 2 at stationary ring and 1 of seal end plate, this rubber L pad plays the effect of oil sealing, prevents outwards leakage of oil.Sum up said structure, the structure of this family expenses pump mechanical sealing spare is more compact, and volume is less, and sealing effect is preferable, is fit to apply on the household series equipment such as home pipeline pump, bathroom recycle pump, family expenses washing machine.
