Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
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, the periphery right side of adjusting sleeve 3 is provided with pump head 4, be provided with static components 5 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, be provided with ceramic seal circle 16 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.Be provided with left side O type circle 14 between moving ring assembly 8 and axle sleeve 7, be provided with groove on moving ring assembly 8, left side O type circle 14 is arranged in described groove, be provided with right side O type circle 17 between described static components 5 and pump head 4, be provided with groove on static components 5, right side O type circle 17 is arranged in described groove.The left side of moving ring assembly and the gap between axle sleeve are provided with wavy spring.Be provided with axle sleeve O type circle between rotor and adjusting sleeve.The left end of moving ring assembly 8 is fixing with axle sleeve 7 by fastening screw trip bolt 10, and is fixing by locating stud 11 between axle sleeve 7 and transmission shaft 13.
During use, because making static components 5, fixes stationary ring back-up ring 6, static components 5 axially can not move, the sealing stability that is conducive to mechanical seal, because there is the shaft shoulder 15 in axle sleeve 7 stage casings, when pressure raises, form the deboost to moving ring assembly 8, reduce the load of wavy spring, historical facts or anecdotes has showed the purpose that high pressure does not leak.When transmission shaft 13 rotor driven 1 running, under pressure, working medium can penetrate into axle sleeve 7 peripheries, 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, due to the effect that wave mode spring 9 is arranged, make seepage discharge very trickle, generally understand direct gasification.Originally unbalanced type mechanical seal, when overpressure, hydraulic coupling can surpass the elastic force of wave mode spring, and liquid is excessive oozing out from the contact gap of ceramic seal circle 16, causes seepage.The mechanical seal of this Novel balance type, fixed moving axially of static components 5 with stationary ring back-up ring 6 on the one hand, on the other hand, when pressure raises, due to the little space of ceramic seal circle 16 left side designs, hydraulic pressure is push shaft cover 7 left, pushes away ceramic seal circle 16 to the right, thereby reduced to a certain extent the load of spring, highly pressurised liquid just is not easy to contact the gap from the ceramic seal circle and oozes out.
The above is only preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., within all being included in protection scope of the present invention.
