Problems solved by technology
[0002] At present, the torque between the dynamic seal and the static seal for the kettle is relatively large under high pressure, which makes this kind of sealing method prone to early failure after long-term operation. Frequent maintenance and replacement of sealing accessories are required, maintenance is troublesome, and the operating cost is high. Once the operation fails, the kettle will fail The internal corrosive substances are easy to leak out and harm human health; and the bearing and the bushing are rigidly fitted, so it is not easy to disassemble

Embodiment
[0009] Embodiment: A sealing machine for a fluid dynamic pressure kettle. At least one groove 1 is provided on the end surface of the static ring. The end face of the ring is lubricated, thereby reducing the torque between the end face of the moving ring. The bearing 2 is fixed on the shaft sleeve 3, and a sealing ring 4 is provided between the bearing and the shaft sleeve, so that the original tight fit between the two can be changed to a through seal. Ring fit, easy to disassemble.
[0010] Eight grooves 1 are evenly spaced on the end face of the static ring.

The invention discloses a hydrodynamic pressure type sealing machine of a kettle. At least one groove is arranged at the end surface of a static ring, and openings at the two ends of the groove are arranged in a sealing liquid flow passage of the external vertical surface of the static ring, so that sealing liquid can pass through the groove to lead the end surface of the static ring to be lubricant, therefore, the torque moment between the end surface of the static ring and the end surface of a moving ring can be reduced; a bearing is fixedly arranged on a shaft housing, and a sealing ring is arranged between the bearing and the shaft housing, so that the bearing and the shaft housing which are closely matched with each other can be changed to be matched with each other by the sealing ring and are easy to be assembled and disassembled. Therefore, the invention has the advantages of prolonging the service life, reducing the power consumption of a motor, as well as being low in running cost and easy to assemble and disassemble the bearing and the shaft housing.
Description
technical field [0001] The invention relates to a sealing device, in particular to a fluid dynamic pressure type kettle sealing machine. Background technique [0002] At present, the torque between the dynamic seal and the static seal for the kettle is relatively large under high pressure, which makes this kind of sealing method prone to early failure after long-term operation. Frequent maintenance and replacement of sealing accessories are required, maintenance is troublesome, and the operating cost is high. Once the operation fails, the kettle will fail Internal corrosive substances are easy to leak and harm human health; and the bearing and the shaft sleeve are rigidly fitted, so it is not easy to disassemble. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a sealing machine for hydrodynamic pressure type kettle, which can prolong the service life, reduce the power consumption of the motor, reduce the o...
