Description
Technical field
The utility model relates to mechanical seal device, particularly a kind of counterbalance spring external mechanical sealing device.
Background technique
The mechanical seal of counterbalance spring external refers to: counterbalance spring is placed in the mechanical seal outside fluid-encapsulated medium.
The mechanical seal of existing counterbalance spring external is for external by counterbalance spring; between compensated loop and compensated ring adaptor, must be provided with slippage auxiliary seal ring; medium and counterbalance spring are isolated; play protection counterbalance spring and be not subject to dielectric corrosion and because impurity in medium crystallization, medium blocks, and make counterbalance spring lose compensation ability.
Although such structure can play the protective action of medium and counterbalance spring isolation, the corrosion resistance that effectively raising machine seals, its spacer medium must be realized with slippage seal ring.This has just formed dynamic sealing point, and dynamic sealing point easily leaks with respect to static seal point, and affects the servo-actuated property of compensated loop, to rubber slippage seal ring material, require high, the easy ageing failure of rubber slippage seal ring, need to often change, and affects the working life of mechanical seal.This will limit the using scope of this machine envelope to a great extent.
Model utility content
The purpose of this utility model is to improve for the shortcoming deficiency of prior art, a kind of shell fragment spacer spring external mechanical sealing device is provided, to overcome the shortcoming deficiency of slippage auxiliary seal ring spacer spring external mechanical sealing device, improve the servo-actuated property of isolating seal and compensated loop, effectively improve working life, to adapt to more wide working condition.
The utility model includes gland 1, static components 2, moving ring assembly 3 and axle sleeve 4, it is characterized in that, static components 2 is encircled by way of compensation, at gland 1, coordinate vertical end face A1 place to be provided with annular isolation shell fragment 5 with the seam of pump housing A, a side or the left and right sides at annular isolation shell fragment 5 are provided with sealing gasket, the outer portion of isolating shell fragment 5 is fixed by gland 1 and pump housing A sealing, the vertical end face of the first stopping table 23 of offering on stationary seat 22 outer ring surfaces of the internal ring portion of annular isolation shell fragment 5 and static components 2 coordinates, on the axial plane of stationary seat 22 first stopping tables 23, being provided with nut briquetting 24 and sealing gasket 25 is sealedly and fixedly connected the internal ring portion of annular isolation shell fragment 5 and stationary seat 22, annular isolation shell fragment 5 cuts off chamber B between stationary seat 22 and pump housing A,
Moving ring assembly 3 is fixedly mounted on axle or axle sleeve 4 and coordinates with static components 2, and the kinetic friction ring 31 of moving ring assembly 3 and the static friction ring 21 of static components 2 coordinate;
On stationary seat 22 outer ring surface front ends, (front portion of the first stopping table 23) offers the second stopping table 26, on this second stopping table 26, is provided with snap ring 6, offers hook 61 on snap ring 6;
On the exterior edge face of gland 1 center hole 11, offer spring seat concave station 12, the inner of spiral counterbalance spring 7 is placed on the spring seat concave station 12 of this gland 1 exterior edge face;
On the end face of gland 1, communicate with center hole 11 to be uniformly distributed and have at least three grooves 14, hook 61 hooks of the snap ring 6 on the inner of spring carrier arm 8 and stationary seat 22 outer ring surface front ends, the outer end hook of the outer end of spring carrier arm 8 and spiral counterbalance spring 7, and counterbalance spring 7 is compressed, counterbalance spring 7 drives static components 2 to compensate by snap ring 6.
For protection counterbalance spring 7 and spring carrier arm 8, on the exterior edge face of gland 1, be fixedly connected with and be provided with protecting jacket 9.
The utility model, by adopting annular isolation shell fragment 5 to make to isolate between stationary ring and pump chamber, is used interior medium in mechanical seal ante-chamber C directly not pass through, and machine sealed cover 1 is not contacted with medium with counterbalance spring 7.Reach the effect of protection spring and machine sealed cover, reduce the material corrosion resistance requirement to machine sealed cover 1 and counterbalance spring 7 simultaneously, greatly reduce the use of noble metal, effectively reduce cost.And counterbalance spring 7 can be by the impurity congestion affects spring 7 compensating action power in medium, and can reduce size and the materials of gland 1.
The utility model annular isolation shell fragment 5 makes compensated loop static components 2 be static seal, good airproof performance, and do not affect the servo-actuated property of compensated loop.There is no slippage seal ring, overcome the easy ageing failure of rubber slippage seal ring, need to often change, affect the mechanical seal problem in working life, promoted the using scope of machine envelope.
The utility model annular isolation shell fragment 5 has compensating element function, its pressure by medium changes face pressure into and acts in compensated loop static components 2, do the used time losing counterbalance spring 7, also can play certain compensating action, prevent from that seal face from producing very early in the morning to leak.
The utility model has effectively utilized the radial space of pump chamber, and particularly suitable axial space urine is used in the occasion that mechanical seal device is installed.
