Maintenance of rotary joint of hydraulic wrench
Nov 29, 2020
Anyone who has used hydraulic wrenches knows that hydraulic wrenches have rotary joints. So, how to maintain the rotary joint of the hydraulic wrench?
1. Keep the rotary joint drum and the inside of the pipe clean. Special attention should be paid to new equipment, and filters should be added when necessary to avoid abnormal wear of the rotary joint caused by foreign objects.
2. If the machine is not used for a long time, it will cause scaling and rusting inside the rotary joint. Please be aware that it may jam or drip when it is used again.
3. If there is an oil injection device, please oil it regularly to ensure the reliability of the rotating joint bearing.
4. The rotary joint that circulates the heating medium should gradually generate temperature to avoid sudden temperature changes.
5. Check the wear condition and thickness change of the sealing surface (normally wear 5-10mm); observe the friction track of the sealing surface to see if there are three-point discontinuity or scratches. If there is any superior condition, it should be immediately replace.
