Abstract

The utility model discloses a mechanical seal experimental tool shaft sleeve stabilizing structure, which consists of a shaft sleeve, a flange bearing and a flange, wherein the shaft sleeve is arranged at one end of the flange through the flange bearing; the flange is arranged on a sealing cavity of a mechanical seal experimental tool. The mechanical seal experimental tool shaft sleeve stabilizing structure is simple in overall structure, safe and reliable, convenient to mount and maintain and low in cost, and has the advantages that (1) according to the flange, the experimental tool is relatively compact in structure and relatively stable, an accident that a screw drops is avoided, the tool is protected, and the improvement cost is reduced as far as possible; (2) a small steel ball is used by the flange bearing, so that the flange bearing has high rotation accuracy, the friction torque is reduced, the axial positioning is relatively simple, and the noise is relatively low; and (3) after a test, the low vibratility and the high stability of the experimental tool adopting the mechanical seal experimental tool shaft sleeve stabilizing structure are obviously improved, so that the experimental accuracy is obviously improved; and therefore, the condition that the sealing effect is influenced by jumping of the shaft sleeve is avoided.

Description

Mechanical seal experiment frock axle sleeve rock-steady structure

Technical field

The utility model relates to mechanical seal experimental technique field, is specifically related to improve the structure that the axle sleeve rotational stabilization of frock is tested in mechanical seal.

Background technique

In the mechanical seal experimentation, the experiment frock has critical role.The stability of experiment frock can influence test result fully, and sealing experiment is scientific and reasonable again to the needs that frock requires to satisfy experiment, requires the practicability Economy.Therefore, to reducing to test the frock Research on Vibration, the novel frock of excellent in design is necessary.

As shown in Figure 1, the axle sleeve 3 of common mechanical sealing experiment frock directly is sleeved among the hold-down ring A3, and is rotatably assorted among the hold-down ring A3, and hold-down ring A3 is installed in the end of Seal cage A1 through end cap A2.The deficiency of ordinary test frock is:

(1) axle sleeve is long, and the axle sleeve afterbody does not reduce the device that vibrates.Thereby axial runout is very big when causing rotation, directly influences the sealing effect of sealing surface, causes leakage;

(2) beat and cause that simultaneously part position friction, noise increase, reduced the working life of sealing, in experimentation, possibly damage sealing simultaneously, cause damage;

(3) exposed outside hold-down ring and long axle sleeve cause security incident etc. easily.

The model utility content

The purpose of the utility model is to provide a kind of mechanical seal experiment frock axle sleeve rock-steady structure, to solve the above problem of existing common mechanical sealing experiment frock axle sleeve.

For reaching the foregoing invention purpose; The technological scheme that the utility model adopted is: a kind of mechanical seal experiment frock axle sleeve rock-steady structure is provided; Comprise axle sleeve; It is characterized in that: said axle sleeve is installed on an end of flange through flange bearing, and said flange is installed on the Seal cage of mechanical seal experiment frock.

This mechanical seal experiment frock axle sleeve rock-steady structure overall structure is simple, safe and reliable, convenient for installation and maintenance, price is low.And have a following advantage:

(1) flange can be good links together experiment frock Seal cage and flange bearing, and compact structure has increased the stability of frock, has prevented the contingency of toner screw, has protected frock simultaneously; Also reduced the improvement cost as much as possible;

(2) flange bearing has used small ball, makes it that good rotating accuracy arranged, and has reduced friction torque, and axially locating is simpler, and noise is littler;

(3) after test, use the low vibratility and the stability of the experiment frock of this mechanical seal experiment frock axle sleeve rock-steady structure obviously to embody, the experiment accuracy is obviously improved.Thereby the situation that makes axle sleeve jumping effect sealing effect is able to get rid of.

Description of drawings

Fig. 1 is the structural representation of the rotation cooperating structure of present common mechanical sealing experiment frock axle sleeve;

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

Wherein, 1, flange; 2, flange bearing; 3, axle sleeve; A1, Seal cage; A2, end cap; A3, hold-down ring.

Embodiment

Below in conjunction with Fig. 2 the embodiment of the utility model is done and to be described in detail:

This mechanical seal experiment frock axle sleeve rock-steady structure is made up of axle sleeve 3, flange bearing 2 and flange 1.Said axle sleeve 3 is installed on an end of flange 1 through flange bearing 2, and said flange 1 is installed on the Seal cage A1 of mechanical seal experiment frock.

The utility model is not limited to above-mentioned instance, in claims institute restricted portion of the utility model, and various distortion that those skilled in the art can make without creative work or revise the protection that all receives this patent.

Claims (1)

1. frock axle sleeve rock-steady structure is tested in mechanical seal; Comprise axle sleeve (3); It is characterized in that: said axle sleeve (3) is installed on an end of flange (1) through flange bearing (2), and said flange (1) is installed on the Seal cage (A1) of mechanical seal experiment frock.
