Separately, above-mentioned traditional black box, bellows is wherein generally flat face with the connecting end of quiet group of seat and contacts, and equally due to the deformation behavior of bellows, is easily subjected to displacement in the process of running up, skidding, thus also can have influence on the stability of sealing.
Model utility content
The utility model, for the above-mentioned deficiency of prior art, provides a kind of guarantee to realize tight seal between quiet group of seat and pump housing mounting hole, bellows not easily displacement, deviates from, and then ensures the mechanical sealing assembly of sealing stability.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of mechanical sealing assembly, comprises moving ring assembly, static components; Described moving ring assembly comprises rotating ring, base and drive sleeve, and described rotating ring to be arranged in drive sleeve and to realize closely cooperating between base and drive sleeve; Described static components comprises quiet group of seat, bellows, stationary seat, stationary ring, spring; Described stationary ring one end and rotating ring fits tightly, the other end is arranged on bellows; Described bellows one end is arranged on stationary seat, the other end is arranged on quiet group of seat; Described spring one end and quiet group of seat against, the other end and stationary seat against; It is characterized in that: the periphery wall of quiet group of described seat is provided with the glue that a circle arches upward and fills up circle, the described cross section filling up circle is arc shaped surface, width is 1-3mm, and maximum ga(u)ge is 0.2-0.3mm; Described quiet group is provided with metallic sheath between seat and stationary ring, and described metallic sheath tightly fits on quiet group of seat and one end of metallic sheath and bellows lean.
Adopt said structure, the glue arched upward owing to being provided with a circle on quiet assembly periphery wall fills up circle, thus substantially overcomes manufacturing deficiency, realizes the effective sealing between pump housing mounting hole; And fill up circle and set specific width, maximum ga(u)ge, realize the effect that minimum jelly realizes at utmost sealing; And being provided with metallic sheath at quiet group between seat and stationary ring, metallic sheath tightly fits on quiet group of seat and the surface of one end of metallic sheath and bellows and leans; Thus realize metallic sheath, quiet group of seat realizes double limitation to bellows, pushes against effect, effectively prevent bellows owing to running up deformation and cause the risk of displacement, disengaging, thus ensure the stability of the sealing effect of whole Sealing further.
As preferably, the described width (along black box axial direction) filling up circle cross section is 23mm, and maximum ga(u)ge (along black box radial direction) is 0.25mm.
As preferably, described metallic sheath comprise with the quiet group of friction tight sticking part of seat sidewall and lean with bellows push against portion; And the length of sticking part is 1.5-3 times that pushes against minister's degree; Employing said structure can ensure the compact siro spinning technology between metallic sheath and quiet group of seat, also can effectively carry out spacing to bellows simultaneously.
As preferably, quiet group of described seat and the joint of bellows are provided with axially extended groove, and described bellows extrusion packing is in groove; Adopt this structure, can improve further quiet group between seat and bellows in conjunction with dynamics, thus the skidding effectively preventing bellows from causing due to deformation or offset phenomena.
