Description
Technical field
The utility model relates to Sealing field, is specifically related to a kind of Sealing.
Background technique
Sealing is widely used in all kinds of running shaft equipment, the especially pump housing.Namely existing pump type seal part main structure passes through the end contact of a dynamic end face and another one static state, and this structure working principle is in sealing medium, is that two sound state end faces form plane contact, completes seal action.During by Sealing frock assembly, drive sleeve is fixed together rotating ring graphite, rubber corrugated pipe, neck ring, spring and spring cup are refilled, so complete moving ring assembly just completes, add static components (stationary ring and stationary ring cover), it is belong to cooperation really up to the mark to start that so a set of Sealing is contained in when water pump uses, and easily produces poor starting, working life is shorter, is difficult to reach the usage requirement of high-quality water pump.
Model utility content
The utility model, for the problems referred to above, provides a kind of Sealing, seal drive sleeve, rotating ring graphite, rubber corrugated pipe is fixed together, adds transmission circle, axle sleeve and fork, makes whole Sealing quality be tending towards more stable, increases the service life.
Technical solution of the present utility model:
A kind of Sealing, comprise rotating ring combination and stationary ring combination, stationary ring combination comprises stationary ring and stationary ring cover, rotating ring combination comprises rotating ring, bellows, drive sleeve, neck ring and spring, wherein rotating ring and bellows fitted seal, be fixed together by drive sleeve, neck ring is placed in drive sleeve rear, spring is placed on neck ring, it is characterized in that: install transmission circle outside described neck ring additional, neck ring rear installs axle sleeve additional, and spring rear installs fork additional, described transmission circle is provided with draw-in groove, and shift fork coordinates screens with transmission circle draw-in groove.
Described bellows material is rubber.
Described rotating ring material is graphite, SIC or alloy.
Described transmission circle, drive sleeve, neck ring, spring, axle sleeve and fork material are stainless steel.
The beneficial effects of the utility model:
The utility model structure is simple, makes movable ring structure more compact, effectively decreases the leakage between endoporus and axle, skidding; The cooperation really up to the mark changed in the past starts, and starts, greatly reduce poor starting phenomenon with axle linked manner; Can load onto easily or take off, easy to use, effectively reduce labor intensity, improve manufacturing efficiency, sealing effect be better, improves machining accuracy, extends working life, can substitute the Grandfos sealing of similar money.
Accompanying drawing explanation
Fig. 1 is the utility model sectional structure schematic diagram.
In figure: 1, stationary ring cover; 2, stationary ring; 3, rotating ring; 4, bellows; 5, drive sleeve; 6, transmission circle; 7, neck ring; 8, spring; 9, shift fork; 10, axle sleeve.
Embodiment
The utility model is illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, Sealing comprises stationary ring cover 1, stationary ring 2, rotating ring 3, bellows 4, drive sleeve 5, transmission circle 6, neck ring 7, spring 8, shift fork 9, axle sleeve 10, wherein rotating ring 3 and bellows 4 fitted seal, be fixed together by drive sleeve 5, and neck ring 7 is placed in drive sleeve 5, spring 8 is placed on neck ring 7, install transmission circle 6 outside neck ring 7 additional, neck ring 7 rear installs axle sleeve 10 additional, and spring 8 rear installs fork 9 additional, transmission circle 6 is provided with draw-in groove, and shift fork 9 coordinates screens with transmission circle 6 draw-in groove.
When Sealing is installed on water pump, first stationary ring is coated with lubricant oil and is arranged on (in cavity) on water pump end cap, the oiling of rotating ring 2 endoporus, surface of contact is enclosed within water pump spindle relatively, is first filled on water pump spindle by fork, then overlaps Upper shaft sleeve, be loaded on spring and rotating ring head, go with frock slighter compress, allow rotating ring and stationary ring rubbing surface fit together closely, be loaded on impeller, end cap
To sum up, the utility model produces a desired effect.
