A kind of mechanical seal structure
Technical field
The utility model relates to centrifugal pump technical field, is specifically related to a kind of structure for sealing centrifugal pump.
Background technique
Centrifugal pump of the prior art, in use, easily there is greasy dirt leakage phenomenon, cause equipment fluctuation of service, maintenance man needs constantly to dismantle centrifugal pump, carries out adding stifled, comparatively waste time and energy in process of production, affect manufacturing efficiency, and how to provide a kind of sealing good centrifugal pump, become the invention technical issues that need to address.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of centrifugal pump seal structure, by centered by described pump shaft, described pump shaft increases corresponding seal approach, promotes integrally-built sealing.
The technical solution of the utility model is as follows:
A kind of sealing configuration, comprise pump shaft, have axle sleeve in the outer race of described pump shaft, described axle sleeve is provided with spring seat, described spring seat is equipped with spring, described spring seat is fixed by screw, at the sidepiece of described spring, rotating ring is housed, and described rotating ring is built with rotating ring O type ring, baffle ring is arranged with outside described rotating ring and described rotating ring O type ring, the sidepiece of described rotating ring is connected with stationary ring, and described stationary ring is fixed by stationary ring O type ring, and described stationary ring is sealed by stuffing box packing; Be equipped with stationary seat in the outer race of described stationary ring and rotating ring, be plugged with stop pin in described stationary seat, the end of described stop pin props up described axle sleeve.
Further, the sidepiece of described stationary seat is arranged with sealing gasket, and described stationary seat can be fixed on described axle sleeve by described sealing gasket.
Beneficial effect: the utility model, by above technological scheme, effectively can promote the overall tightness of the pump housing, contributes to saving time in process of production, and be conducive to maintenance, be not only conducive to enhancing productivity, and can reduce costs.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the sectional structure schematic diagram of a kind of sealing configuration disclosed in the utility model embodiment.
Numeral and the corresponding part title represented by letter in figure:
1, axle sleeve; 2, sealing gasket; 3, spring seat; 4, spring; 5, throw-out collar; 6, rotating ring O type ring; 7, baffle ring; 8, rotating ring; 9, stationary ring O type ring; 10, stationary ring; 11, stuffing box packing; 12, stop pin; 13, stationary seat; 14, sealing gasket; 15, screw; 16, pump shaft.
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.
Embodiment
A kind of sealing configuration, comprise pump shaft 16, axle sleeve 1 is had in the outer race of described pump shaft 16, described axle sleeve 1 is provided with spring seat 3, described spring seat 3 is equipped with spring 4, and described spring seat 3 is fixed by screw 15, at the sidepiece of described spring 4, rotating ring 8 is housed, by described spring 4, the degree of tightness state of described rotating ring 8 can be adjusted.
Described rotating ring 8 is built with rotating ring O type ring 6, and described rotating ring O type ring 6, between described rotating ring 8 and described axle sleeve 1, can carry out clamping from the inner side of described rotating ring 8 to described rotating ring 8.
Outside described rotating ring 8 and described rotating ring O type ring 6, be arranged with baffle ring 7, baffle ring 7 can protect from outside to whole seal.
Be connected with stationary ring 10 at the sidepiece of described rotating ring 8, described stationary ring 10 is fixed by stationary ring O type ring 9, and described stationary ring 10 is sealed by stuffing box packing 11; Be equipped with stationary seat 13 in the outer race of described stationary ring 10 and described rotating ring 8, now, because described stationary seat 13 energy and described baffle ring form docking, or it is inner described baffle ring 7 to be enclosed within described stationary seat 13, guarantees integrally-built steadiness.
In described stationary seat 13, be plugged with stop pin 12, the end of described stop pin 12 props up described axle sleeve 1, and the sidepiece of described stationary seat 13 is arranged with sealing gasket 14, and described stationary seat 13 can be fixed on described axle sleeve 1 by described sealing gasket 14.
As shown in Figure 1, the pump housing is in operation process, and described pump shaft 16 is in rotary course, the sealing configuration of axle sleeve 1 periphery is connected as a single entity, effectively can tackle greasy dirt, but also can be adjusted described rotating ring 8 by described spring 3, meet at a high speed and the using state of low speed.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
