Description

A kind of mechanical seal device

Technical field

The utility model relates to technical field of sealing technology, is specially a kind of mechanical seal device.

Background technique

At present, mechanical seal is the sealing means that most of equipment adopts, sealing is leaked gas or is sealed not tight, capital makes its sealability decline, and some seal arrangements do not have the performance of heat radiation, the frictional heat that surface of contact is produced not easily is distributed, and makes the temperature difference of rotating ring and stationary ring inner and outer surface large, and end face easily deforms even hot tearing.

Model utility content

The purpose of this utility model is to provide a kind of mechanical seal device, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technological scheme: a kind of mechanical seal device, comprise rotating ring, stationary ring and spring, the lower end of described spring mounts elastically, upper end connects the lower end surface of throw-out collar, the lower end surface of described rotating ring connects the upper-end surface of throw-out collar, and spring promotes rotating ring by throw-out collar, the front-end face of described rotating ring contacts with the ear end face of stationary ring and connects, described rotating ring, stationary ring is located at the inside of gland rear end successively, described rotating ring is enclosed within axle sleeve by seal ring of moving ring, described stationary ring fixed cover is in the front end of axle sleeve, the exterior edge face central boss of described stationary ring is provided with stationary ring seal ring, the upper end of described rotating ring front-end face has oil outlet, the upper end face of rear end has filler opening, described spring seat, spring, throw-out collar, rotating ring, stationary ring is from left to right enclosed within axle sleeve successively.

Preferably, the material of described rotating ring and stationary ring is the alloy material that Tungsten carbite and nickel form.

Preferably, described gland inner upper end and filler opening joint are provided with oily passage, and lower end base is provided with oil-return groove.

Preferably, described throw-out collar is High Strength Structural Steel.

Preferably, the spring pressure of described spring is 1-6Mpa.

Compared with prior art, the beneficial effects of the utility model are: the mechanical seal device of this model utility, by oil film, rotating ring, stationary ring are sealed, sealing place is not only made to have lubricity, also greatly improve the tightness of sealing, and axle sleeve interior lower end is provided with oil-return groove, oil ceaselessly circulates at sealing surface, the fricative heat of sealing surface is taken away by oil, makes this mechanical seal device have good thermal diffusivity.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model movable ring structure schematic diagram.

In figure: 1 rotating ring, 2 stationary rings, 3 stationary ring seal rings, 4 glands, 5 seal ring of moving ring, 6 throw-out collars, 7 springs, 8 spring seats, 9 axle sleeves, 10 filler openings and 11 oil outlets.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1 and Fig. 2, the utility model provides a kind of technological scheme: a kind of mechanical seal device, comprise rotating ring 1, stationary ring 2 and spring 7, the lower end of described spring 7 is arranged on spring seat 8, upper end connects the lower end surface of throw-out collar 6, the lower end surface of described rotating ring 1 connects the upper-end surface of throw-out collar 6, and spring 7 promotes rotating ring 1 by throw-out collar 6, described throw-out collar 6 is High Strength Structural Steel, the front-end face of described rotating ring 1 contacts with the ear end face of stationary ring 2 and connects, the material of described rotating ring 1 and stationary ring 2 is the alloy material that Tungsten carbite and nickel form, described rotating ring 1, stationary ring 2 is located at the inside of gland 4 rear end successively, described gland 4 inner upper end and filler opening 10 joint are provided with oily passage, lower end base is provided with oil-return groove, cold oil can be reused, described rotating ring 1 is enclosed within axle sleeve 9 by seal ring of moving ring 5, described stationary ring 2 fixed cover is in the front end of axle sleeve 9, the exterior edge face central boss of described stationary ring 2 is provided with stationary ring seal ring 3, the upper end of described rotating ring 1 front-end face has oil outlet 11, the upper end face of rear end has filler opening 10, described spring seat 8, spring 7, throw-out collar 6, rotating ring 1, stationary ring 2 is from left to right enclosed within axle sleeve 9 successively, the spring pressure of described spring is 1-6Mpa.

Working principle: the upper end face filler opening 10 of oily driven torus 1 rear end flows to, and the oil outlet 11 of driven torus 1 front-end face upper end flows out, and finally forms the oil film of one deck densification between rotating ring 1 and stationary ring 2, carries out mechanical seal.
