Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, a kind of Novel balance type rotor pump mechanical seal composite structure of the present invention, comprise transmission shaft 13, the right side of transmission shaft 13 is provided with rotor 1, the left side of transmission shaft 13 is provided with bearing front shroud 12, the left side of the periphery rotor of transmission shaft 13 is provided with adjusting sleeve 3, pump head 4 is provided with on the right side of the periphery of adjusting sleeve 3, static components 5 is provided with on the left of the periphery of adjusting sleeve 3, the periphery of static components 5 is provided with stationary ring back-up ring 6, the left side of the periphery adjusting sleeve 3 of transmission shaft 13 is provided with axle sleeve 7, the periphery of axle sleeve 7 is provided with moving ring assembly 8, ceramic seal circle 16 is provided with between static components 5 and moving ring assembly 8.The middle part of axle sleeve 7 is provided with the shaft shoulder 15, is provided with a space between the left side of ceramic seal circle 16 and the shaft shoulder 15.Left side O type circle 14 is provided with between moving ring assembly 8 and axle sleeve 7, moving ring assembly 8 is provided with groove, left side O type circle 14 is arranged in described groove, right side O type circle 17 is provided with between described static components 5 and pump head 4, static components 5 is provided with groove, and right side O type circle 17 is arranged in described groove.Gap between the left side of moving ring assembly and axle sleeve is provided with wavy spring.Axle sleeve O type circle is provided with between rotor and adjusting sleeve.The left end of moving ring assembly 8 is fixed by fastening screw trip bolt 10 and axle sleeve 7, is fixed between axle sleeve 7 and transmission shaft 13 by locating stud 11.
During use, because stationary ring back-up ring 6 makes static components 5 fix, static components 5 axially can not move, be conducive to the sealing stability of mechanical seal, because there is the shaft shoulder 15 in axle sleeve 7 stage casing, when pressure raises, form the deboost to moving ring assembly 8, reduce the load of wavy spring, therefore achieve the object that high pressure do not leak.When transmission shaft 13 rotor driven 1 operates, under pressure, it is peripheral that working medium can penetrate into axle sleeve 7, left side O type circle 14 and the right side O type circle 17 of ceramic seal circle 16 have all blocked oozing out of liquid, so can only ooze out from the contact gap of ceramic seal circle 16, owing to there being the effect of wave mode spring 9, making seepage discharge very trickle, generally understand direct gasification.Originally unbalanced type mechanical seal, when overpressure, hydraulic coupling can exceed the elastic force of wave mode spring, and liquid is excessive from the contact gap of ceramic seal circle 16 to ooze out, and causes seepage.The mechanical seal of this Novel balance type, one side stationary ring back-up ring 6 secures moving axially of static components 5, on the other hand, when pressure raises, due to the little space of design on the left of ceramic seal circle 16, hydraulic pressure is push shaft cover 7 left, pushes away ceramic seal circle 16 to the right, thus decreasing the load of spring to a certain extent, highly pressurised liquid is just not easy to ooze out from ceramic seal circle contact gap.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., be all included within protection scope of the present invention.
