Abstract
The invention provides an integrated type axial mechanical sealing device, which consists of an end closure (1), two stator ring components (2a, 2b), a rotor ring (3), a compensation spring (4), a positioning card (8) and gasket rings (6, 7) of the stator rings and the rotor ring, wherein the compensation spring (4) is arranged in a spring mounting hole (4) and on a plug (23) of a stator ring seat (22); the sealed end closure (1) and a stator ring seat (24) of the outside stator ring component (2b) are correspondingly provided with a neck hole (18) and a neck (25); and the outside stator ring component (2b) and the sealed end closure (1) are fixed through the positioning card (8) to form the double end face packaged type axial mechanical sealing device. The integrated type axial mechanical sealing device has a simple structure, is convenient for processing, manufacturing and assembling, is convenient to use and install with the packaged type structure, and can ensure accuracy of assembly without causing damage to matched ends of the stator rings and the rotor ring.
Description
Technical field
What the present invention relates to is shaft sealer, particularly mechanical seal for axle.
Background technique
Mechanical seal for axle is the seal arrangement that rotating ring cooperates with stationary ring under the effect of compensating element, compensating element has spring and bellow type, rotating ring is combined with single end face with stationary ring and cooperates, also there is Double End to cooperate, according to different applying working conditions and performance requirement, concrete structure has nothing in common with each other, and in the prior art, various mechanical seal device is arranged.
Require not really high shaft sealing for sealability, the shaft sealing of no internal pressure, the simplest is to adopt the seal ring sealing, for reaching better sealing effect, then adopt the sealing of mechanical seal device replacement seal circle, the spring type mechanical sealing device that is applied to use in this occasion is to be made of the dynamic and static ring that pair of matched is closed, stationary ring axially slidably is installed on the shaft-cup under stop pin cooperates, between shaft-cup and stationary ring, be provided with counterbalance spring, rotating ring is installed on the axle by rotating seat, and is provided with outer end cap and mechanical seal device is carried out integral installation fixes.The shortcoming deficiency of this prior art structure is, mechanical seal device is that resolution element is assembled on axle and the shaft-cup, the element that is formation mechanical seals such as rotating ring, stationary ring, counterbalance spring will be installed at the scene, because the cooperation of mechanical seal device requires high, this field-mounted process is not only operated inconvenience, and be not easy to guarantee installation precision, and in installation process, also cause the damage of dynamic and static ring abutting end easily, influence sealability.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, good airproof performance, integration type shaft mechanical seal device easy for installation.
The present invention is by end cover, two static components, a rotating ring, counterbalance spring, positioning cards, and the dynamic and static ring sealing circle constitutes, on the stopping table interior edge face of end cover, offer spring mounting hole, on the stationary seat of the static components that is installed in the end cover inboard, be provided with pin, counterbalance spring place in the spring mounting hole and the stationary seat pin on, another static components cooperates installation by its stationary seat with the external port of end cover, rotating ring is installed in the centre of two static components, forming the Double End rubbing surface cooperates, on the stationary seat outer shroud of outside static components, be provided with seal ring, on the interior ring of rotating ring, be provided with seal ring, on end cover, have the draw-in groove hole, correspondence has draw-in groove on the stationary seat outer shroud of outside static components, positioning cards is installed in this draw-in groove hole and the draw-in groove, outside static components and end cover are fixed, be about to rotating ring, two stationary rings, the double end-face mechanical sealing device collection that counterbalance spring constitutes is contained in the end cover.
The present invention is simple in structure, is convenient to manufacturing and assembling, double density end-blocking good airproof performance, and its unit loading type constitutes, and guarantees installation precision, and installation easy to use can not cause the damage of dynamic and static ring abutting end, and is easy to install.
