The mechanical seal device is characterized in that the mechanical seal device further comprises a stationary ring seat arranged on the pump body, a rubber sleeve is arranged inside the stationary ring seat, a spring is arranged on the outer wall of the rubber sleeve, a stationary ring is arranged between the rubber sleeve and the stationary ring seat, a moving ring seat is arranged on the pump shaft, a moving ring sleeve is arranged on the moving ring, a moving ring is arranged inside the moving ring sleeve and engaged with the stationary ring, and a seal ring is arranged between the pump shaft and the moving ring seat. The pressure bearing capacity of the seal device reaches 12MPa and the rotational speed is 7000 n/min, thereby meeting the requirements of high pressure, high lift and high pump shaft rotational speed.
Description
Technical field
The utility model relates to mechanical seal device, particularly relates to a kind of mechanical seal device that is used for pump class pressurized container housing and rotating shaft, is particularly useful for the sprayer peripheral pump.
Background technique
The method of mechanical seal is adopted in sealing between the pump housing and the rotating shaft usually.Prior art mainly is by a pair of or several to making the end face of slide relative perpendicular to axle, in elastic force (or magnetic force) effect of hydrodynamic pressure and compensation mechanism down, keeps fitting and is equipped with auxiliary seal and reaches the gland seal device of resistance leakage.The compensation mechanism of existing mechanical seal (mainly comprise spring, rubber sleeve form) designs in the rotating ring side, rely on pressure spring and rubber sleeve to keep the applying of rotating ring and stationary ring, and pack tightly rotating shaft by the rubber sleeve that was compressed, reach the transmission of axial seal and rotating ring.The rotation of rotating shaft, rubber sleeve and spring drive rotating ring and slide at the stationary ring face, rotating speed is high more, the torsion that rubber sleeve and spring bear is just big more, and centrifugal force also increases, and rubber sleeve, spring can produce beats, make rotating ring generation off-centre and eccentric wear, the increase of torsion is skidded rubber sleeve and pump shaft, influences its sealing effect, shortens its working life.Simultaneously, the mechanical seal of this structure also can only solve pressure below 0.8MPa, and rotating speed is in the slow-revving pump sealing of 3000n/min.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of and can satisfy the pressure height, and rotating speed is fast, and sealing part abrasion is few, the pump of long service life rotor axis mechanical seal arrangement.
The utility model pump with the technological scheme of rotor axis mechanical seal arrangement is: comprise the pump housing, rotating shaft is installed in the pump housing, between the pump housing and rotating shaft, mechanical seal device is arranged, it is characterized in that described mechanical seal device comprises the stationary seat that is installed on the pump housing, rubber sleeve is installed in the stationary seat, the outer wall mounting spring of rubber sleeve, between rubber sleeve and stationary seat, stationary ring is installed, rotating seat is installed on the pump shaft, moving ring sleeve is installed on the rotating seat, rotating ring is installed in the moving ring sleeve, and rotating ring and stationary ring fit, and are equipped with seal ring between pump shaft and the rotating seat.
Pump of the present utility model rotor axis mechanical seal arrangement, stationary seat is installed on the pump housing, rubber sleeve and spring are installed in the stationary seat, and rotating ring is installed in moving ring sleeve and the rotating seat, rotating seat is fixed on the pump shaft, and when the pump shaft high speed rotating, the torsion of its generation is born by rotating seat and rotating ring, rubber sleeve in the stationary seat and spring only provide the rotating ring high speed rotating, produce beat and axially high pressure make nose balance effect when producing the gap between rotating ring and stationary ring.Therefore quite little to the influence of rubber sleeve and spring and stationary ring; protected the working life of spring and rubber sleeve like this; be to be fastened on the pump shaft simultaneously because of rotating ring and rotating seat; can not produce bigger beating with the increase of centrifugal force; therefore can well guarantee fitting tightly of dynamic and static ring, not produce off-centre and eccentric wear, side leakage does not take place; simultaneously between pump shaft and rotating seat, be equipped with seal ring, solved the sealing of pump shaft and housing.And make the sealing device can bear pressure and reach 12MPa, rotating speed 7000n/min has satisfied high pressure, and is high-lift, the requirement that the pump shaft rotating speed is high.
Pump of the present utility model rotor axis mechanical seal arrangement, its described rubber sleeve outer wall mounting spring seat, spring mounts elastically, and spring seat is arranged, and spring is installed reliable.Be shaped on breach on its described pump shaft, rotating seat is installed on the breach, installs firmly.Be shaped on groove on its described pump shaft, seal ring is installed in the groove, and groove has been arranged, and it is firm that seal ring is installed.
