Abstract
The utility model discloses a multi-function mechanical seal, which comprises a bush, a moving ring, a static ring, a spring seat, a spring and a plunger ring. The moving ring and the static ring are arranged on the bush in sequence; the spring seat is arranged on the static ring, the spring is arranged on the spring seat; a positioning hole is formed on the lateral surface of the spring seat, and the plunger ring is arranged at the end part of the spring seat. The device has the advantages of good seal performance, good capability of bearing larger pressure and wide application range, which can be used in various mediums and in liquid containing solid particles.
Description
Technical field
The utility model relates to a kind of seal arrangement, is a kind of multifunctional mechanical sealing specifically.
Background technique
Mechanical sealing element is to be used for preventing the component that fluid or solid particle are invaded from leakage and introduced contaminants such as dust, silt, moisture etc. between adjacent junction plane.For all kinds of pumps, sealing is to belong to most important parts, weighs the quality quality of a pump, except the flow of pump and lift, efficient, sees exactly whether its sealing is qualified.The sealing of all kinds of pumps all has its characteristic and advantage, and its shortcoming is also arranged.Particularly pump carry all kinds of have the medium solid particle and high-lift in, be an acid test to the usability of all kinds of sealings.A lot of sealings are fit to the liquid that still is not suitable for containing solid particle of clear liquid, and the honeybee of suitable conveying solid substance particle-liquid is not suitable for carrying clear liquid.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of all kinds of media that are suitable for, and comprises use in the liquid that contains solid particle, the multifunctional mechanical sealing that load-bearing is bigger.
Technological scheme: a kind of multifunctional mechanical sealing, it comprises lining, rotating ring, stationary ring, spring seat, spring and trim ring, is provided with rotating ring and stationary ring on lining successively, the stationary ring place is provided with spring seat, spring is installed on the spring seat, and the spring seat side is provided with positioning hole, and the spring seat end is provided with trim ring.
The shaft shoulder and the rotating ring of described lining fixedly mount by stop pin.
Lining is fixedlyed connected by key with stationary ring.
Surface of contact place, stationary ring and spring seat place, spring seat and trim ring contacting point at lining and rotating ring are respectively equipped with seal ring.
During work, multifunctional mechanical sealing is installed on the rotatingshaft of pump, and rotatingshaft is connected with bush threads, and rotatingshaft drives lining and rotates with the fixedly connected rotating ring of lining when rotating.Stationary ring is fixedlyed connected with spring seat, spring seat is then fixedlyed connected with the pump housing, the seal ring that is installed in surface of contact place, stationary ring and spring seat place, spring seat and the trim ring contacting point of lining and rotating ring can effectively prevent the medium of the pump housing, goes out as leakages such as solid, liquid.
Beneficial effect: (1) good seal performance of the present utility model, the physical life of the pump shaft that can extend greatly; (2) pressure that can bear is bigger, can reach 20KG, is equivalent to the height that pump can be carried liquid to 200 meter; (3) applied widely, can comprise in the liquid that contains solid particle and using at all kinds of media simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model user mode figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Multifunctional mechanical sealing of the present utility model as shown in Figure 1 comprises lining 1, rotating ring 2, stationary ring 3, spring seat 4, spring 5 and trim ring 6.End at lining 1 is provided with the shaft shoulder, is set with rotating ring 2, stationary ring 3 and spring seat 4 on the lining 1 successively, and lining 1 shaft shoulder end face is fixedlyed connected by stop pin with rotating ring 2 one ends; One end face of the other end of rotating ring 2 and stationary ring 3 joins, and stationary ring 3 is arranged between rotating ring 2 and the spring seat 4, and the other end of stationary ring 3 is provided with keyway, and the key on the spring seat 4 is installed in the keyway, and can certain displacement be arranged along keyway.Key slot ends contacts with the spring 5 that is installed in spring seat 4 inside.Be provided with the location shaft shoulder at spring seat 4 ends, trim ring 6 is installed on the shaft shoulder of location.Contacting point at lining 1 and rotating ring 2 is provided with seal ring, also is provided with seal ring at stationary ring 3 with spring seat 4 places, is provided with the another one seal ring in spring seat 4 and trim ring 6 contacting points.
As shown in Figure 2, when mounted, lining 1 is installed on the rotatingshaft, with gland whole device is fixed to pump housing inside again, one group of locating stud is fixed on spring seat 4 on the pump housing, and another group locating stud is fixing with spring seat 4 with stationary ring 3, driving lining 1 when rotatingshaft rotates rotates, lining 1 drives rotating ring 2 by stop pin and rotates, and stationary ring 3 does not rotate with spring seat 4, and spring seat 4 is in the axial motion that can do certain distance along the keyway of stationary ring 3.Can prevent medium along lining 1 outer round surface seepage at lining 1 and the seal ring that rotating ring 2 contacting points are provided with, the seal ring that is provided with between seal ring, spring seat 4 and the trim ring 6 of stationary ring 3 outsides and the setting of spring seat 4 places can prevent the surface of contact seepage of medium along the seal arrangement and the pump housing.
The utility model provides a kind of thinking and method of multifunctional mechanical sealing; the method and the approach of this technological scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
