Abstract
The utility model relates to mechanical sealing devices, in particular to a novel domestic pump mechanical sealing part. The novel pump mechanical sealing part is composed of a sealing bin, a rubber washer, a static ring, a movable ring, a corrugated pipe, a shaft sleeve, fasteners, a spring and a spring gasket. The sealing bin comprises a sealing gland which is provided with a cooling liquid pipeline. The static ring makes close contact with the movable ring. The corrugated pipe is arranged between the movable ring and the shaft sleeve. The fasteners are arranged inside the corrugated pipe and the shaft sleeve respectively. The spring is arranged between the shaft sleeve and the spring gasket. The novel pump mechanical sealing part is reasonable in structural design and small in size.
Description
Technical field
The utility model relates to mechanical seal device, relates in particular to a kind of Novel domestic pump mechanical sealing part.
Background technique
Along with scientific and technological progress, the raising of people to equipment requirement, make the problem that original device body is large more outstanding.Existing mechanical sealing element for domestic pump comprises that the elastic support be 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 indent annular corrugated pipe face, the middle axial plane fluid-tight engagement of the extended surface of bellows face and pump; Stationary ring overlaps on peripheral axial plane establishes the ridge be parallel to each other.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 meets the various pump class installation requirements of same diameter different heights, do not affecting in 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.This mechanical sealing element deficiency is that volume is larger, is further improved in configuration aspects.
Summary of the invention
The utility model is for above deficiency, and a kind of reasonable in design, new pump machinery Sealing that volume is little are provided.
the technological scheme that the utility model adopts is:
A kind of new pump machinery Sealing, by gas-tight silo, rubber washer, stationary ring, rotating ring, bellows, axle sleeve, fastening piece, spring, compression spring, formed, gas-tight silo comprises sealing gland, sealing gland is provided with coolant duct, wherein stationary ring and rotating ring close contact, be provided with bellows between rotating ring and axle sleeve, in bellows and axle sleeve, be provided with fastening piece, between axle sleeve and compression spring, be provided with spring.
Be provided with rubber washer between described sealing gland and stationary ring, this packing ring plays the effect of oil sealing, prevents that oil is to outward leakage.
Described bellows is affixed on axle sleeve, and rotating ring is arranged on the bellows inwall, and while making pump shaft rotate, drive axle sleeve and rotating ring rotate together.
Described spring is volute spring, and volute spring promotes rotating ring and stationary ring close contact, and volute spring reduces the axial distance of mechanical sealing element, has dwindled the volume of this mechanical sealing element.
the utility model beneficial effect is:
Structural design is more reasonable, and volume is little.
The accompanying drawing explanation
Figure l is structural representation of the present utility model.
In figure 1, compression spring, 2, spring, 3, fastening piece, 4, bellows, 5, axle sleeve, 6, rotating ring, 7, stationary ring, 8, rubber washer, 9, sealing gland.
Embodiment
As shown in drawings, a kind of new pump machinery Sealing, by gas-tight silo, rubber washer 8, stationary ring 7, rotating ring 6, bellows 4, axle sleeve 5, fastening piece 3, spring 2, compression spring 1, formed, gas-tight silo comprises sealing gland 9, sealing gland 9 is provided with coolant duct, and wherein stationary ring 7 and rotating ring 6 close contacts, be provided with bellows 4 between rotating ring 6 and axle sleeve 5, be provided with fastening piece 3 in bellows 4 and axle sleeve 5, between axle sleeve 5 and compression spring 1, be provided with spring 2.
Be provided with rubber washer 8 between described sealing gland 9 and stationary ring 7, this packing ring plays the effect of oil sealing, prevents that oil is to outward leakage.
Described bellows 4 is affixed on axle sleeve 5, and rotating ring 6 is arranged on bellows 4 inwalls, and while making pump shaft rotate, drive axle sleeve 5 and rotating ring 6 rotate together.
Described spring 2 is volute spring, and volute spring promotes rotating ring 6 and stationary ring 7 close contacts, and volute spring reduces the axial distance of mechanical sealing element, has dwindled the volume of this mechanical sealing element.
