Abstract
The invention discloses a sealing device of a rotation apparatus. The sealing device of rotation apparatus comprises a sealing element body provided with a sealing gas ring cavity, a sealing gas inlet and a sealing gas nozzle. The sealing gas ring cavity is installed in the sealing element body. One end of the sealing gas inlet is communicated with the sealing gas ring cavity. One end of the sealing gas nozzle is communicated with the sealing gas ring cavity, and the other end is communicated with the outside world. An end face flange of an outer cylinder, corresponding to the sealing gas nozzle, is provided with annular sealing filler. While the outer cylinder is rotated, the sealing element body contacts with the annular sealing filler to form the dynamic-static sealing plane through a pressing component. A sealing gas with certain pressure enters the sealing gas ring cavity through the sealing gas inlet on the sealing element body, and the sealing gas is sprayed from the sealing gas nozzle under the pressure action. A uniform air curtain formed by the sprayed gas is distributed on the original dynamic-static sealing plane. The sealing effect of the sealing element is enhanced, the efficient sealing effect is realized, and the application range of the original dynamic-static sealing component is broadened.
