Abstract
The utility model relates to an adjustable mechanical sealing device, which comprises a bellows component composed of bellows 8, a spring 7, a ring-shaped seal head 6 and a conical seal head 9. The inner side of a ring body of the ring-shaped seal head 6 is matched with a circular protrusion of a movable ring 4, and a sealing rubber pad 5 is arranged between the end part of the circular protrusion and the bottom part of the ring body. The inner conical surface of the conical seal head 9 of the bellows and the end part of a conical adjusting sleeve 12 are respectively provided with an O-shaped sealing ring 10, and the conical adjusting sleeve 12 is fixed by a stop screw 11. The left side of a movable ring is also provided with a stationary ring 3 and a rubber pad 2 to reshape an old pump. The utility model has the advantages of good sealing performance and convenient maintenance.
Description
The utility model relates to the seal arrangement in the mechanical field, especially a kind of outside adjustable mechanical seal device of machinery that is loaded on.
For preventing that oil or water in the machinery from leaking, widely used Sealing Device has seal ring, sealing gasket and packing etc., and individual device also has the adjustable mechanical seal device that adopts interior dress.These air lockings are difficult for adjusting the pressure at sealing position, thereby when seal pressure less or wearing and tearing after, sealability is relatively poor, especially to the sealing at the sealing of highly pressurised liquid or moving parts kinematic pair position difficulty more, existing adjustable mechanical seal device mostly is built-in type, and inconvenience is picked up and repaiied and adjust.
The purpose of this utility model is the poor sealing performance at the sealing components and parts existence of present use, and problems such as inconvenient maintenance provide a kind of adjustment, pick up and repair conveniently, and good seal performance is suitable for the adjustable mechanical seal device that pump class high-tension apparatus uses especially.
The utility model is achieved in that
Adjustable mechanical seal device comprises bellows component, rotating ring and taper adjustment cover.The bellows component left end is a cup-shaped end socket, and right-hand member is a conical head, and spring is positioned at bellows.The cup of cup-shaped end socket round platform inboard and on the rotating ring cooperates.Between the round platform termination of rotating ring and the bottom of cup of cup-shaped end socket seal rubber pad is housed.Be shaped on annular seal groove on the end face of rotating ring.The cone match of the inner conical surface of conical head and taper adjustment cover.Between the top of taper adjustment cover and the conical head inner conical surface O RunddichtringO is arranged.The taper adjustment puts has stop screw.
There is a stationary ring in the rotating ring left side, and the stationary ring left side is provided with rubber pad.
The rotating ring material is preferably graphite or pottery, and the bellows material is a metal.During use, rubber pad, stationary ring, rotating ring, seal rubber pad, bellows component and O RunddichtringO, taper adjustment cover are enclosed within on the pump shaft successively, to the bellows component pressurization and with stop screw taper adjustment cover are fixed on the pump shaft by taper adjustment cover.When pump shaft rotated, rotating ring, bellows component and taper adjustment cover all rotated thereupon, because the friction between stationary ring and rubber pad and the rafter rubber cushion and the pump housing is bigger, thereby the stationary ring transfixion.Stationary ring and rotating ring surface of contact relatively rotate.Because this surface of contact cooperates tight, is shaped on annular seal groove on the rotating ring again, adds the pressure of upper spring, so can liquid body exudate on the fitting surface.Equally, under the strict seal of rubber pad, O-ring seal and O RunddichtringO, liquid oils or water can not overflow along any gap of pump shaft.
With compare with seal approach such as packing and internally mounted mechanical seal devices, the utility model advantage is to pick up to repair conveniently good seal performance.
Accompanying drawing is a tectonic maps of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
Adjustable mechanical seal device comprises rotating ring 4, taper adjustment cover 12 and bellows component.Bellows component comprises bellows 8, and bellows 8 left ends have a cup-shaped end socket 6, and right-hand member has a conical head 9.A spring 7 is arranged in the bellows 8.The cup of cup-shaped end socket 6 is inboard to be cooperated with the round boss of rotating ring 4, and a seal rubber pad 5 is arranged between round boss and the bottom of cup.To the repacking of old pump, the left side of rotating ring 4 can be provided with stationary ring 3 and rubber pad 2 again, and be placed on rubber pad 2 and stationary ring 3 in the former groove that packing is housed this moment.To new pump, can on the pump housing, process the polishing plane that coincide closely with rotating ring, need not to make stationary ring 3 and rubber pad 2.The inner conical surface of the conical head 9 on bellows 8 right sides cooperates with the male cone (strobilus masculinus) of taper adjustment cover 12.The front end of taper adjustment cover 12 has an O RunddichtringO 10.Taper adjustment cover 12 usefulness stop screws 11 axially locating.For improving sealability, rotating ring 4 is shaped on annular seal groove 13 with the surface of contact of stationary ring 3.
Claims (2)
