Maintenance method of pneumatic clutch
1. Cleaning the friction linings
After the clutch work for a period of time, it will cause friction lining slip due to contamination of oil, should be cleaned in time. When cleaning, adding gasoline from the view port (not diesel), and then start the engine, the clutch in neutral state operation with 3-4min, put the net flameout and dirty oil, plus clean gasoline, in accordance with the law to clean, let the clutch operation in the separation state for a while, can put the friction surface cleaning clean lining.
2. Adjust the clearance correctly
In the locomotive operation, because of the wear of the friction lining or the loosening of the fastening bolts, the gap between the clutch parts will change and affect its normal operation, so it is necessary to check and adjust the clutch clearance regularly. For example, the clearance between the ball head and the separating bearing of the Dongfanghong -75 clutch is 3.5-4.5mm, and the corresponding pedal free stroke is 30-35mm.
3, the clutch bearing, shaft should be lubricated regularly
Clutch bearing grease gun extrusion 3-4 times, if too much oil, easy to smear the friction lining, resulting in clutch slipping. Some of the locomotive bearings are separated by closed structure, usually do not play butter, maintenance, remove the bearing, placed in the melting of the melted butter, to be removed after cooling.
