Abstract
The utility model relates to a radial double-ended mechanical sealing device, comprising a dynamic ring (1) and a static ring (2) which coordinate with each other. The utility model is characterized in that two round grooves (10, 20) arranged at the end faces corresponding to the dynamic ring (1) and the static ring (2) form two coordination friction pairs at the radial direction; a flow discharging hole (21) is arranged at the static ring (2) to form the radical double-ended mechanical seal; the dynamic ring (1) is connected with a shaft sleeve (3) under the coordination of an auxiliary sealing ring; the static ring (2) is connected with an end cover (6) under the coordination of a movable auxiliary sealing ring; a plurality of springs (5) are arranged at the bottom of the mounting groove of the static ring at the end cover (6) and can be pushed up to the top for the compensation of the back end of the static ring (2). The utility model has the advantages of simple and compact structure, small structural space, convenient installation and use and applicability to the occasions when the radial installation size is limited.
Description
Technical field
The utility model relates to mechanical seal device, is a kind of seal arrangement that prevents that working fluid from leaking along running shaft.
Background technique
Mechanical seal device claims face seals again, by at least one pair of rotating ring and stationary ring perpendicular to axis, and rotating ring its end face and stationary ring end face keep the applying slip formation that is rotatably assorted down in elastic compensating (bellows or spring) mechanism effect.Rotating ring is connected with shaft drive, and stationary ring is connected with end cap, rotates by rotating ring and stationary ring friction pair slide relative and finishes the rotation axis seal effect.
Radial direction double end-face mechanical sealing device of the prior art, no matter be that rotating ring or stationary ring are as compensated loop, compensated loop all is that two split rings by inside and outside setting constitute, compensated loop cooperates radially two friction fit pairs of formation with the uncompensated ring end face, and corresponding respectively two compensated loops are provided with individual compensation mechanism certainly, form radial double mechanical seal, though it has the technique effect of oneself, but its overall structure space is bigger, radial dimension is big, inconvenience is installed, and influence is installed and used on equipment, and its application is also therefore limited.
The model utility content
The purpose of this utility model is to improve at above-mentioned the deficiencies in the prior art, and a kind of compact structure that has is provided, and uses radial direction double end-face mechanical sealing device easy for installation.
The technical solution of the utility model is to include a pair of rotating ring that cooperatively interacts 1 and stationary ring 2, correspondence offers ring groove 10 on rotating ring 1 and stationary ring 2 counterfaces, 20, make the rotating ring 1 and the counterface of stationary ring 2 form radially two friction fit pairs, ring groove 20 on the corresponding stationary ring 2 axially offers discharge orifice 21 on stationary ring 2, be that rotating ring 1 forms radial double mechanical seal with stationary ring 2, rotating ring 1 is at auxiliary seal ring 12,13 cooperate down with axle sleeve 3 on the mounting groove offered be connected, stationary ring 2 is at slippage auxiliary seal ring 22,23 cooperate down with end cap 6 on the mounting groove offered be connected, the bottom of the stationary ring mounting groove on end cap 6 is distributed and is provided with spring base hole 61 and spring 5, and spring 5 ejections act on stationary ring 2 rear ends and carry out the stationary ring compensation.
The utility model adopts the overall structure friction pair, structural strength is good, the counterface distortion is little, stationary ring 2 as compensated loop is a monocycle, and corresponding its is provided with spring 5 compensation mechanisms, and its overall structure is simply compact, structure space is little, radial structure and installation dimension are little, and be easy to install, is specially adapted to radially installation dimension occasions with limited use.
