Description
Technical field
The utility model relates to a kind of mechanical seal improved device
Background technique
The existing mechanical sealing mainly contains a kind of built-in type, and another kind is an external mounted.One, internally mounted mechanical seal, be installed in the pump chamber the inside, whole mechanical seal all is immersed in the liquid the inside, because the working medium scope of chemical industry is wide at present, like this, the mechanical seal material of liquid the inside must be subjected to the restriction of chemical mediator, even improve the rotproofness of material, that will inevitably increase the cost of mechanical seal, and is obviously uneconomical; The second, it is higher to contain particle, the medium of easy crystallization, and this mechanical seal also is restricted, thereby has caused external mechanical seal, though described chemical mediator restriction before external mounted machine envelope has solved contains the particle height but can not solve, easily the material of crystallization.
Summary of the invention
New model utility has overcome deficiency of the prior art, and a kind of steady, anti-particle that turns round, corrosion-resistant, high temperature resistant, mechanical seal improved device that the life-span is long are provided.
Mechanical seal improved device of the present utility model comprises: rotating ring, stationary ring, " O " type circle, shift fork, stationary seat, gland, spring, stainless steel gasket, oil sealing, stainless steel platen, water-cooling tube, described impeller back root part position is embedded with rotating ring, described stationary ring is by being loaded on stationary seat, embedded O type circle, described shift fork supports the stationary seat of front by the balance type spring in back, shift fork, spring, stationary seat are that benchmark schedules one with the gland, embedded O type circle.
Dynamic and static ring in the described mechanical seal improved device adopts high density carbon to make, and O type circle is a rubber in adopting, and wrapped in teflon, balance type turn to big spring to adopt spring steel outsourcing tetrafluoro arbitrarily.
Mechanical seal improved device of the present utility model, beneficial effect is: impeller back root part position is embedded with rotating ring in the pump, support the stationary seat of front by the back gland, in the adjusting (utilizing O type circle elasticity) of O type circle is arranged, the shift fork that has a next balance type big spring to support is again regulated the cooperation between the dynamic and static ring, like this, for some the medium of particle is arranged, be difficult for entering mechanical seal inside, this structure, thus guaranteed that liquid has not entered the mechanical seal the inside, obviously, the utility model mechanical seal improved device, it is hard to have filled up pump high particle of fed sheet of a media solid content in mechanical seal device is housed widely, the blank that crystallized stock is arranged; Cause occurring in the pump taking off liquid for some solid contents than higher medium, usual operator's carelessness, easily damage machine envelope.Mechanical seal improved device of the present utility model is connected with chilled water unit outward, has further improved the using scope of this device by this cooling of installing inner bistrique.Because dynamic and static ring adopts high density carbon, big spring adopts the outsourcing tetrafluoro, a technological innovation of embedded O type circle outsourcing tetrafluoro all can guarantee under many, the hard condition of solid particle can both obtain satisfied solution in the machine envelope of improved device for containing in the media such as the number acid in the current chemical industry, alkali, salt, organic solvent.

The utility model discloses a kind of improved mechanical sealing device, it comprises: rotating ring, stationary ring, O type circle, shift fork, stationary seat, Gland, spring, stainless steel gasket, oil sealing, stainless steel platen, described impeller button root position is embedded with rotating ring, described stationary ring Be installed in the stationary seat, embedded O type circle, described shift fork is by the stationary seat of balanced type spring supporting front, back, originally Utility model has smooth running, anti-particle, corrosion-resistant, high temperature resistant, characteristics that the life-span is long.
Embodiment:
According to Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, this practical mechanical seal improved device is embedded in impeller (2) back root part and closely cooperates by there being rotating ring (4) neck that quiet O type circle a (3) is housed, next stationary ring (5) has quiet O type circle b (8) and is embedded in closely linking of stationary seat (7), then shift fork (6) balance type big spring (10) gland (9) dress is compressed for one and bonnet (1), water in order to ensure water-cooling tube (11) is returned stream, oil sealing (13) is housed at the pump shaft rear portion, there is stainless steel platen (14) fixing outward in gland (9), in stainless steel gasket (12) balance support type big spring (10) is arranged, thereby this practical mechanical seal improved device and inside, impeller root position have formed an interior tank.Rotating ring (4), stationary ring (5) all adopt high density carbon to make, and O type circle a (3), O type circle b (8) balance type big spring (10) all adopt wrapped in teflon.
Claims (2)
1, a kind of mechanical seal improved device, comprise rotating ring, stationary ring, shift fork, stationary seat, O type circle a, O type circle b, gland, balance type big spring, stainless steel gasket, oil sealing, stainless steel platen, it is characterized in that: one, described impeller back root part position is embedded with rotating ring; Its two, described stationary ring is installed on and is embedded with O type circle in the stationary seat; Its three, described shift fork supports the stationary seat of front by the balance type big spring in back, shift fork, spring, stationary seat are that benchmark is in the embedded O type of one circle with the gland.
According to the described mechanical seal improved device of claim, it is characterized in that 2, described dynamic and static ring adopts high density carbon to make, O type circle is a rubber in adopting, wrapped in teflon, and big spring adopts the spring steel wrapped in teflon.
