Abstract
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
The present invention relates to a kind of seal arrangement, especially a kind of Hydrodynamic pressure type sealing machine of kettle.
Background technique
At present still with between motive sealing and static seal under high pressure conditions moment of torsion bigger, make after this sealing means long-term operation early failue easily, need often maintenance, change encapsulation fitting, troublesome maintenance, operating cost height, and in case running when losing efficacy still internal corrosion material release easily and injure health; Bearing and shaft room are rigid drive fit again, and be not easy to assemble like this.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of Hydrodynamic pressure type sealing machine of kettle, this Hydrodynamic pressure type sealing machine of kettle can increase the service life, and can reduce motor power consumption, operating cost is low and bearing and axle sleeve easy disassembling.
The present invention for the technological scheme that solves its technical problem and adopt is: a kind of Hydrodynamic pressure type sealing machine of kettle, the stationary ring end face is provided with at least one groove, the sealing fluid runner of groove both ends open facade outside stationary ring, sealing fluid can be lubricated the stationary ring end face through groove like this, thereby reduced and the rotating ring end face between moment of torsion, bearing is fixedly arranged on the axle sleeve, bearing and shaft room are provided with seal ring, both original drive fits are become by seal ring cooperate, dismounting easily.
Further technological scheme of the present invention is: the stationary ring end face evenly is interval with eight grooves.
The invention has the beneficial effects as follows: because the stationary ring end face is provided with groove, the sealing fluid runner of groove both ends open facade outside stationary ring, sealing fluid can be lubricated the stationary ring end face through groove like this, thereby reduced and the rotating ring end face between moment of torsion, bearing is fixedly arranged on the axle sleeve, bearing and shaft room are provided with seal ring, both original drive fits are become by seal ring cooperate, dismounting easily.Therefore this example can increase the service life, and can reduce motor power consumption, operating cost is low and bearing and axle sleeve easy disassembling.
