II. Use of Crushing Hammer
1. Appearance inspection before crushing hammer operation
Check the gap between the drill rod and its bushing and see if there is any hydraulic oil leakage. Once hydraulic oil leakage is found in the crushing hammer, the damaged sealing ring should be replaced immediately. And check whether the relevant bolts are loose or falling off. If necessary, tighten or replace them.
2. Lubrication before/during crushing hammer operation Crushing hammer should be lubricated before operation and within 2 to 3 hours of continuous operation. When butter is beaten, the hammer should be placed vertically. The fibre rod should be compacted and not suspended, so that butter can not enter the hydraulic system. It should be noted that butter should not be injected too much. Too much butter will stick to the piston. Butter will easily enter the hydraulic system when it is re-operated.
