Disc is divided into disc 1 and following disc 8, and the concrete structure of former disc is following:
The defective of structure existence at present is:
1, former disc body 14 lobe numbers are more, and the level in the anabolic process between each lobe, highly difficult adjustment cause combinating face dislocation causing leakage of oil easily.
2, combinating face is the rigidity contact, and when local high spot appearred in combinating face, it was not tight to cause combinating face to fit easily, causes leakage of oil.Therefore each combinating face all should clean before combination totally, guarantees not have defectives such as high point, burr.The more maintenance link that causes of lobe number is more loaded down with trivial details, and the repair quality control point is more, the also corresponding increase of probability that while equipment breaks down.
3, owing to the disc seal groove designs in former disc body 14 inboards, and 14 inboard and main shaft 21 applyings of former disc body cause the installation of Stamping Steel Ribbon comparatively difficult.According to conventional mounting process; With 14 groups of circles of former disc body; Penetrate the combinating face bolt but not fastening, be not adjacent between the former disc body 14 of each lobe this moment, the internal diameter of disc internal diameter when it is in place; Therefore disc seal groove diameter is bigger than normal, and Stamping Steel Ribbon can't be put into seal groove before disc is fastening; After the combinating face bolton, former disc body 14 is inboard fits with main shaft 21, and all by shutoff, Stamping Steel Ribbon can't be put into groove after former disc body 14 is fastening around the disc seal groove 15.Therefore, generally take when installing at present earlier on main shaft 21, to cement Stamping Steel Ribbon, move the method that former disc body 14 makes its inner seal groove dock with Stamping Steel Ribbon then.Though the method can solve the installation question of Stamping Steel Ribbon, installation process still can not get effective control, and seal groove is difficult to observe the accurate position of Stamping Steel Ribbon in docking operation, and former disc body 14 is difficult for adjustment.
4, former disc body 14 diameters are bigger, in carrying and installation process, are easy to generate distortion, cause circularity to exceed standard, and the sealing crush is inhomogeneous, and regional area sealing crush causes oil impregnate inadequately.
