Abstract
The utility model discloses a sealing device for a high-pressure and high-speed reactor. The sealing device comprises a moving ring, a moving ring sealing ring and a main shaft, wherein the moving loop is fixedly sleeved at the outer side of the main shaft, the moving loop sealing ring is positioned in a radial clearance between the moving loop and the main shaft, and by using a using direction as a reference, an annular baffle ring is arranged in an axial clearance between the moving ring and the end surface of the moving ring sealing ring. The sealing device can prolong the service life of the moving ring sealing ring, ensure a sealing effect and avoid bad sealing of the moving ring sealing ring after the moving ring sealing ring is deformed at a high temperature and a high pressure; in a using process, once the annular baffle ring is damaged, the annular baffle ring can be directly replaced, and the moving ring sealing ring does not need to be replaced, so that the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of high-voltage high-speed reactor seal arrangement.
Background technique
At present, with in the seal arrangement, only adopt the seal ring of moving ring sealing between its rotating ring and the main shaft, and in high temperature and high pressure environment, the rotating ring easy deformation is damaged, changed cumbersomely, influence manufacturing efficiency at high-voltage high-speed reactor commonly used.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of high-voltage high-speed reactor seal arrangement, and this device can improve the working life of seal ring of moving ring, guarantees excellent sealing performance.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of high-voltage high-speed reactor seal arrangement; comprise rotating ring and seal ring of moving ring and main shaft; the rotating ring fixed cover is located at the main shaft outside (during work; rotating ring 1 rotates with main shaft 4); seal ring of moving ring (is preventing the gap leakage between medium driven torus and the main shaft 4 between the radial clearance of rotating ring and main shaft; seal); to use direction to be benchmark; be provided with an annular retaining ring between the axial clearance of described rotating ring and seal ring of moving ring end face; annular retaining ring is set plays the effect of effective protection seal ring of moving ring; increase seal ring of moving ring working life; guarantee sealing effect; avoid seal ring of moving ring because the poor sealing that High Temperature High Pressure distortion back produces; in the using process,, can directly change in case annular retaining ring damages; and do not need to change seal ring of moving ring, easy to operate.
As further improvement of the utility model, the radial clearance of described annular retaining ring and main shaft is between the 0.05-0.1 millimeter.
As further improvement of the utility model, to use direction to be benchmark, described annular retaining ring is provided with the annular groove of indent near the end face of seal ring of moving ring one side, in this example, annular retaining ring is provided with the annular groove of indent near the end face of seal ring of moving ring one side, (can also not establish the annular groove of indent, annular retaining ring is a horizontal plane near the end face of seal ring of moving ring one side), the groove structure that is provided with indent can reduce area of contact, thereby reduces friction longer service life.
As further improvement of the utility model, described annular retaining ring is that the elastic material of high temperature high voltage resistant is made, and with in the seal arrangement, annular retaining ring need bear higher ambient temperature and pressure at the high-voltage high-speed reactor, adopt the elastic material of high temperature high voltage resistant to make, can improve its usability.
The beneficial effects of the utility model are: this high-voltage high-speed reactor is provided with an annular retaining ring with seal arrangement between the axial clearance of described rotating ring and seal ring of moving ring end face, can increase the working life of seal ring of moving ring, guarantee sealing effect, avoid seal ring of moving ring because the poor sealing that High Temperature High Pressure distortion back produces, in the using process,, can directly change in case annular retaining ring damages, and do not need to change seal ring of moving ring, enhance productivity.
