The Shaft End Seal Design of Twin Shaft Mixer
Aug 28, 2020
For a long time, the shaft end sealing technology has been restricting the development of the twin shaft mixer. As a twin shat concrete mixer manufacturer, Haomei Machinery adopts various improvement measures to effectively increase the life of the shaft end seal.
1. Open seal
An elastic sealing ring is added between the shaft sleeve and the dust cover to make the outer cavity in a closed state, and the grease does not directly contact the cement, which effectively avoids the intrusion of the cement slurry.
The amount of oil supplemented only needs to meet the lubrication consumption between the elastic sealing ring and the rotating hub, and the amount of oil entering the mixing zone during use is less.
Add an adjustment pad between the shaft sleeve and the dust cover, and the gap adjustment has nothing to do with the sealed cavity, which avoids the influence of grease leakage on the pressure of the sealed cavity due to improper installation.
Improved rear shaft end seal design:
1. Sliding hub 2. Floating sealing ring 3. Sealing ring 4. J-shaped sealing ring 5. Rotating hub 6. Sealing gasket 7. Dust pad 8. Wear ring
2. Closed shaft end seal
Improved rear shaft end seal design:
1. Mixer shell 2. Shaft head protection ring 3. Fixed moving gap 4. Side arm limit ring 5. Short shaft sleeve 6. Dust ring 7. O-ring 8. Pressure plate 9. Yellow glue fixing bracket 10. Yellow Glue 11. One-way sealing ring 12. Shaft locker 13. Gland 14. Skeleton seal ring 15. Support bearing assembly
With the improved shaft end sealing design, the twin shaft mixer will have longer stable working performance and will have lower maintenance cost. Welcome to leave message below to get the best price of China twin shaft concrete mixer.
