Now the emergence of hydraulic jacks has been widely used in various places. The jack stand manufacturers in china collected Some jack use skills.
In the process of use, the inner wall of the hydraulic jack cylinder may be scratched due to some conditions. What is the reason for this situation?
The wear of the piston rod or cylinder body during plating hard: the cylinder body of the hydraulic jack is processed into semi-finished products on the lathe and sent to the electroplating workshop. After the plating of the hard cylinder, it is lifted by a heavy-duty truck during the hoisting journey. Scratches caused by collision or collision with uneven ground due to the influence of its own gravity during placement.
Foreign matter mixed into the cylinder during the assembly process: After the assembly parts are processed, they are sent to the assembly workshop. If foreign matter accidentally enters the cylinder during the assembly process, it will cause problems in the future use of the product.
Damage to the inner wall of the cylinder. This kind of foreign matter may come from the external environment, or it may be the cylinder body burr remaining in the cylinder body during the smoothing process. Therefore, before the total assembly of the hydraulic jack, all parts must be fully deburred and cleaned, and carefully check whether there is any residue between and inside the internal friction parts. Make sure the parts are clean and complete before assembly.
In many production operations, the use of jack stand improves work efficiency. Workers have also accumulated a lot of jacks experience for users in actual work.
Sundries enter the cylinder accidentally during cleaning: filter should be installed when cleaning the cylinder, otherwise it is easy to have sundries in the cylinder during cleaning.
This will not only fail to clean the cylinder, but also make the cylinder Foreign body flowing into the body is counterproductive. Once the miscellaneous material enters the cylinder, it will be difficult to eliminate it. At this time, the user must return to the manufacturer without special maintenance personnel to let the manufacturer help clean up.
The oil port is not sealed during normal maintenance: the oil port is placed for a long time without being sealed, and it is easy to enter the debris. This is absolutely not allowed. Therefore, after the hydraulic jack is used up, it is necessary to cover the hydraulic jack with oil. Oil port.
