Abstract

The utility model discloses a novel container-type mechanical sealing device, which belongs to the field of mechanical sealing. The novel container-type mechanical sealing device comprises a shaft sleeve, a rotating ring, a stationary ring and a spring, wherein the rotating ring is sheathed in the shaft sleeve, the stationary ring is arranged at one end of the rotating ring, a gland is arranged at the upper end of the stationary ring, and the spring is arranged in the gland. In the rotating ring of the device, a whole ring is adopted to directly installed in the shaft sleeve, therefore, an inlaying technique is reduced, mechanical sealing dimensions can be reduced, and cost can be saved; in the device, a thrust ring is not arranged, the spring directly acts on the stationary ring, therefore, design size of mechanical sealing is smaller, cost is lower, assembly is convenient, and the service life is greatly prolonged.

Description

A kind of novel integrated mechanical sealing device

Technical field

The utility model relates to a kind of seal arrangement, particularly a kind of mechanical seal device.

Background technique

At present; The structure of general integrated mechanical sealing device is as shown in Figure 1, comprises axle sleeve 1, rotating ring 2, stationary ring 3 and throw-out collar 6, and there is following shortcoming in the seal arrangement of this structure: on the one hand; The structure rotating ring 2 general embedded structures that adopt of this sealing; Reinstall in the axle sleeve 1, so longer dimension, cost is higher; On the other hand, stationary ring 3 generally is the split design with throw-out collar 6, is two independent two different parts, also causes longer dimension, and cost is higher.This seal arrangement is installed on the equipment, all needs bigger bulk, thereby has just increased equipment cost, has also increased the cost of mechanical seal, and the profit of product is reduced, thereby product is reduced in the competitive ability in market.In addition, if outside framework oil seal or other packing seal are adopted in the position that need seal equipment, its working life is shorter, and be will damage in 2-3 month general working life, changes continually, just has a strong impact on production.

Summary of the invention

The goal of the invention of the utility model is: to the problem of above-mentioned existence, provide a kind of long service life installation dimension short, mechanical seal device applied widely.

The technological scheme that the utility model adopts is such: a kind of novel integrated mechanical sealing device; Comprise axle sleeve, rotating ring, stationary ring and spring; Wherein, said rotating ring is set in the axle sleeve, and an end of said rotating ring is provided with stationary ring; Said stationary ring upper end is provided with gland, and said spring is arranged in the gland.

In sum, owing to adopted technique scheme, the beneficial effect of the utility model is: the rotating ring of this device adopts overall loop directly to pack in the axle sleeve, has reduced mosaic technology, has promptly reduced the mechanical seal size, has practiced thrift cost again; This device is not provided with throw-out collar, and spring acts directly on the stationary ring, so the design size of mechanical seal is less, cost is lower, and is easy to assembly, and also prolong greatly working life.

Description of drawings

Fig. 1 is the structural representation of the utility model background technique;

Fig. 2 is the structural representation of the utility model.

Mark among the figure: 1 is axle sleeve, 2 rotating rings, and 3 stationary rings, 4 is gland, and 5 is spring, and 6 is throw-out collar.

Embodiment

Below in conjunction with accompanying drawing, the utility model is done detailed explanation.

For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As shown in Figure 2; A kind of novel integrated mechanical sealing device comprises axle sleeve 1, rotating ring 2, stationary ring 3 and spring 5, wherein; Said rotating ring 2 is set in the axle sleeve 1; One end of said rotating ring 2 is provided with stationary ring 3, and said stationary ring 3 upper ends are provided with gland 4, and said spring 5 is arranged in the gland 4.

During work, through axle sleeve 1 rotation, 2 rotations of driven rotary ring, spring 5 designs are not staticly rotated in gland 4, thereby make the axial size of mechanical seal become shorter, more can bear higher rotating speed; Stationary ring 3 is a balanced structure, thereby the pressure that mechanical seal is born becomes bigger; Adopt the unit loading type structure, make it to install more convenient.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.

Claims

1. a novel integrated mechanical sealing device is characterized in that: comprise axle sleeve, rotating ring, stationary ring and spring, wherein; Said rotating ring is set in the axle sleeve; One end of said rotating ring is provided with stationary ring, and said stationary ring upper end is provided with gland, and said spring is arranged in the gland.
