Abstract
This utility model relates to an improved rubber corrugated tube mechanical sealing element in the mechanical sealing element field, designed to solve the problem that the prior rubber corrugated tube often breaks up. This utility model is characterized in that the rubber corrugated tube is radially and interference fit connected with a water pump shaft via a lower metal punching element to prevent leakage between the sealing element and the shaft and rotate around the shaft. The lower metal punching element and an upper metal punching element are mutually plugged in and connected via an axial concavo-convex slot to make the rubber corrugated tube unaffected by the axial moment of torsion, a moving ring sleeved into the rubber corrugated tube is permanently connected with the rubber corrugated tube via the upper metal punching element and rotates with the shaft in the rubber corrugated tube. A spring is arranged between the upper metal punching element and the lower metal punching element to provide axial force to make the moving ring and a stationary ring closely applied and rotate relative to each other, overcoming break-up of the rubber corrugated tube. This utility model is applicable to sealing of the centrifugal pump with certain spread and application value.
Description
Technical field
The utility model relates to the mechanical sealing element field, is applicable to the sealing of centrifugal pump.
Background technique
At present, rubber bellows mechanical seal spare is widely used in the sealing that single stage centrifugal pump is carried various liquid, but rubber bellows mechanical seal spare design fashion does not take into full account the rotation direction of centrifugal pump, the mutual suction effect of structure and actual using process mechanical sealing element friction pair.Make rubber corrugated pipe often to occur by spring transmission rubber bellows mechanical seal spare and break, and influence its working life.
Summary of the invention
The purpose of this utility model is the problem at above-mentioned existence, provides a kind of modified model rubber bellows mechanical seal spare to related domain, makes it can solve the technical problem that rubber corrugated pipe breaks.The purpose of this utility model is to adopt following technological scheme to realize.
A kind of modified model rubber bellows mechanical seal spare, the sealing part is made up of stationary ring sealing gasket 1, stationary ring 2, rotating ring 3, rubber corrugated pipe 4, spring 5, last metallic stamping pieces 6, following metallic stamping pieces 7, its main points are that rubber corrugated pipe 4 is connected in water pump spindle 8 by following metal towards part 7 radial interference fit, prevent to reveal between Sealing and the axle, and rotate with axle.Following metallic stamping pieces is inserted mutually by axial tongue and groove with last metallic stamping pieces 6 and is connected, make rubber corrugated pipe not be subjected to axial moment of torsion, rotating ring 3 is inserted in the rubber corrugated pipe, is fixedly connected on rubber corrugated pipe by last metallic stamping pieces, and rotates with the axis in rubber corrugated pipe.Spring 5 is installed in the middle of metallic stamping pieces and the following metallic stamping pieces, and axial force is provided, and rotating ring is fitted tightly and relative rotation with stationary ring.
By above-mentioned technological scheme, change original spring transmission into the metallic stamping pieces transmission, promptly upper and lower metallic stamping pieces being designed to tongue and groove inserts mutually, make follow-on mechanical sealing element not be subjected to the difference of centrifugal pump rotation direction power, and cause spring loosening, overcome the phenomenon that rubber corrugated pipe breaks.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Mode of execution is installed as example with the utility model.The stationary ring sealing gasket 1, stationary ring 2, rotating ring 3, rubber corrugated pipe 4, spring 5, last metallic stamping pieces 6, the following metallic stamping pieces 7 that assemble are inserted in water pump spindle 8, from the inner bolt hole of locating piece 9, screw in holding down bolt again, this modified model rubber bellows mechanical seal spare is rotated with the rotation of water pump spindle 8, and the rubber corrugated pipe fracture phenomena has just solved substantially.The utility model design is because of rotation direction and structural feature according to centrifugal pump, and in conjunction with the mutual suction effect of actual using process mechanical sealing element friction pair.By spring transmission and last metallic stamping pieces 6, combining of metallic stamping pieces 7 down, modified model rubber bellows mechanical seal spare is improved working life.
