Maintenance and care of rotary joints in hydraulic wrenches
source:Industry News release time:2022-03-24 Article author:Rosit Popular:Air band saw
Anyone who has used hydraulic wrenches knows that hydraulic wrenches have swivel joints. And the tool has been used for a long time, and its internal parts also need proper maintenance, in order to facilitate the better use of the hydraulic wrench in the future. Today, the editor will reveal how to maintain the rotary joint.
The rotary joint drum and the interior of the pipe should be kept clean. Special attention should be paid to new equipment, and if necessary, a filter should be added to avoid abnormal wear on the rotary joint caused by foreign matter.
Since the machine is not used for a long time, it will cause scaling and rusting inside the rotary joint. Please pay attention to the occurrence of sticking or dripping when it is used again.
For those with oil injection device, please inject oil regularly to ensure the reliability of the rotating joint bearing operation.
The rotary joint that circulates the heating medium should gradually generate temperature to avoid sudden temperature changes.
Check the wear condition and thickness change of the sealing surface (generally normal wear is 5-10mm); observe the friction track of the sealing surface to see if there are three-point discontinuities or scratches and other problems. If the above is the case, it should be replaced immediately.
