Abstract
The utility model relates to a novel horizontal multistage pump balance disc structure which comprises a balance disc. The utility model is characterized in that the axle is mounted with a balancing rig, the balance ring is sheathed on the axle surface of the balancing rig, the opposite annular planes of the balancing rig and the balance ring are provided with friction rings, and a rubber gasket is provided between the friction rings an the balancing rig. The friction rings are connected with the balancing rig via bolts and the rubber gasket is annular. The horizontal multistage pump balance disc structure has the advantages that the rubber gasket is provided between the friction rings and the balancing rig, therefore the friction rings have certain freedom relative to the balancing rig to eliminate the effect of geometric tolerance of the axle and balancing rig, to confirm the parallel degree between the friction rings and the friction surface of the balance ring, the utility model can effectively improve the stability and service life of the whole balance structure.
Description
Technical field
The utility model relates to a kind of multistage pump Balance disc, particularly a kind of novel horizontal multistage pump Balance disc structure.
Background technique
The Balance disc of existing horizontal multi-stage centrifugal pump when mounted, Balance disc is installed on the axle by the tolerance fit of H7/h6, again by the antero posterior axis cover screwing, Balance disc and the axle between relative position fix.Produce the discontinuity friction between Balance disc and the gimbal during Balance disc work, make the Balance disc front and back produce dynamic differential pressure, play the effect of balancing axial thrust with this.Because Balance disc and gimbal operating time crack are between 0～0.02mm, so when assembling Balance disc and gimbal between the position relation require just very high, again since Balance disc and axle position fix, so axle, gimbal, the form and position tolerance between the Balance disc three have determined the operation stability and the life-span of Balance disc parts.But above three's position relation is difficult to again measure during the pump assembling, and this has just caused potential faults.Behind the pump operation certain hour, because factors such as vibrations can cause the Concentricity tolerance of axle to increase, the parallelism between Balance disc and the gimbal just can't guarantee thus, thereby causes the Balance disc eccentric wear, Balance disc and gimbal were worn and torn in the short time, thereby whole balanced controls are scrapped.
Summary of the invention
The purpose of this utility model be solve between the Balance disc of horizontal multi-stage centrifugal pump in the prior art and the gimbal since between the rubbing surface parallelism be difficult to guarantee to make the whole balanced controls lost of life, need the often problem of replacing, a kind of novel horizontal multistage pump Balance disc structure that can overcome above-mentioned shortcoming is provided.The utility model designs a kind of novel horizontal multistage pump Balance disc structure, comprise gimbal, it is characterized in that: balancing stand is housed on axle, and the balance annular space is enclosed within on the axial plane of balancing stand, on the balancing stand disk relative, friction ring is arranged, between friction ring and the balancing stand rubber sheet gasket is arranged with gimbal.Friction ring is connected on the balancing stand by bolt, and rubber sheet gasket is a ring-type.The utility model has the advantages that: owing to added rubber pad between friction ring and balancing stand, so friction ring has level of freedom with respect to balancing stand, the influence that this has just eliminated axle and balancing stand form and position tolerance has guaranteed the parallelism between friction ring and gimbal rubbing surface.The stability and the working life of whole balanced controls have also just effectively been improved.
Description of drawings
Accompanying drawing is the designed Balance disc structural representation of the utility model.
Below in conjunction with drawings and Examples the utility model is elaborated
Embodiment
Owing to make original whole Balance disc into friction ring 4 and balancing stand 3, add that between the two rubber sheet gasket 5 connects by bolt 6 again.The benefit of doing like this is: because friction ring 4 and 3 of balancing stands have added rubber sheet gasket 5, so friction ring 4 has level of freedom with respect to balancing stand 3, the influence that this has just eliminated axle 1 and balancing stand 3 form and position tolerances has guaranteed the parallelism between friction ring 4 and gimbal 1 rubbing surface.The stability and the working life of whole balanced controls have also just effectively been improved.
