Before and After Modification
BeforeBefore 1 O1 O--ring sealingring sealing need big rotate torqueneed big rotate torque1. O1. O ring sealing ring sealing need big rotate torque.need big rotate torque.2. 2. Much load on Motor.Much load on Motor.33. Contact sealing way cause short life time.. Contact sealing way cause short life time.44. Timing belt . Timing belt degadatedegadate due to due to big rotate torquebig rotate torque..55. Sudden leak due to O. Sudden leak due to O--ring improper contact.ring improper contact.55. Sudden leak due to O. Sudden leak due to O ring improper contact.ring improper contact.
AfterAfter 1. Magnetic 1. Magnetic seal is non contact Sealing with small torque.seal is non contact Sealing with small torque.22 Minimize Motor loadMinimize Motor load2. 2. Minimize Motor load.Minimize Motor load.3. 3. Enlarge life time over X2 since non contact sealing.Enlarge life time over X2 since non contact sealing.44. Use timing . Use timing bbelt long time.elt long time.55. Simple modification.. Simple modification.66 Able to forecast Leak and PM timingAble to forecast Leak and PM timing66. Able to forecast Leak and PM timing.. Able to forecast Leak and PM timing.
