Abstract
The utility model discloses a spring-type two-end-face mechanical sealing device. The spring-type two-end-face mechanical sealing device comprises a frame body (1), two stationary rings (3a, 3b) symmetrically arranged on the frame body(1), a plurality of compensating springs (2) which are arranged on the frame body (1) and act on the stationary rings (3a, 3b), a moving ring (4), a frame body sealing ring (5), stationary ring sealing rings (6a, 6b), and a sealing ring (7). The spring-type two-end-face mechanical sealing device has strong adaptation ability for the axial quenching and the radial quenching, and is uneasy affected by temperature, having simple structure, convenient manufacturing, mounting, and use, and long service life.
Description
Technical field
The utility model relates to the mechanical seal device that pump or rotating equipment prevent that liquid from leaking along rotating shaft, especially for the device of rotary machine bearing lubrication oil seal.
Background technique
The single end face magnetic mechanical sealing device is arranged in the existing mechanical seal arrangement, with the Double End magnetic mechanical sealing device that on the basis of single end face magnetic mechanical sealing device, forms, as the MagTecta magnetic double-face seal arrangement that U.S. A ESSEAL company produces, it is to attract the stationary ring sheet to do compensation with magnet steel to cooperate with the rotating ring sheet.This mechanical seal device also has its narrow limitation and deficiency, magnet steel can produce demagnetization under higher temperature, do compensation with magnetic attraction stationary ring sheet and cooperate the not only requirement on machining accuracy height of making own with the rotating ring sheet, and very high to the axial movement value requirement, so also high to the device fabrication required precision.
The model utility content
It is easy that the purpose of this utility model provides a kind of manufacturing processing, adaptable spring double end-face mechanical sealing device.
The utility model includes support body 1, symmetry and is installed in two stationary ring 3a, 3b on the support body 1, is installed in the some counterbalance springs 2, rotating ring 4, support body seal ring 5, stationary ring seal ring 6a, 6b, the seal ring of moving ring 7 that act on stationary ring 3a, 3b on the support body 1 and constitutes, stationary ring 3a, 3b and support body 1 seam sliding connection, seal ring 6a, 6b are set between its fitting surface, support body 1 cooperates to install with bearing support or bearing gland 9 and is connected, and seal ring 5 is set between fitting surface, rotating ring 4 is installed in the rotating shaft 8.
The utility model two stationary ring 3a, 3b and support body 1 are by stationary ring seal ring 6a, 6b sealing, and two stationary ring 3a, 3b can be in support body 1 axial float, have certain floatability, rely on spring 2 thrust two stationary ring 3a, 3b to be fitted in its two ends with rotating ring 4 and compensate.It is strong that it adapts to the Device for elimination of axial-and radial-play ability, is difficult for temperature influence, simple in structure, manufacturing, installation, easy to use, long service life.
Description of drawings
Accompanying drawing is the utility model example structure schematic representation.
Embodiment
The utility model is installed in two stationary ring 3a, 3b on the support body 1, is installed in the some counterbalance springs 2, rotating ring 4, support body seal ring 5, stationary ring seal ring 6a, 6b, the seal ring of moving ring 7 that act on stationary ring 3a, 3b on the support body 1 and constitutes by support body 1, symmetry.Support body 1 is with bearing gland 9 stationary fits and by seal ring 5 sealings, the end cap 10 of support body 1 one sides links into an integrated entity by welding and support body, two stationary ring 3a, 3b and support body 1 seam sliding connection, seal ring 6a, 6b are set between its fitting surface, rotating ring 4 is installed in the rotating shaft 8 by seal ring 7, spring 2 is circle distribution and is installed in the spring eye of offering on the support body 1, and spring thrust acts on stationary ring 3a, 3b, makes the both ends of the surface of stationary ring 3a, 3b and the both ends of the surface applying of rotating ring 4 carry out motive sealing.But the utility model two stationary ring 3a, 3b follow-up ring 4 and axle 8 be axially reciprocating together, by the elastic compensating power effect of spring 2, makes the end face of two stationary ring 3a, 3b not separated with the both ends of the surface maintenance applying of rotating ring 4 all the time in this process, keeps motive sealing.
