Cavitation is the surface damage caused by the relative movement of a solid surface and a liquid, and such problems also occur in the spiral swing oil cylinder during use. So, what to do if cavitation occurs during the use of the function?
First, ensure that the clearance of each hydraulic component on the joint surface is normal. When repairing or manufacturing the oil cylinder, be sure to assemble it according to the lower limit of the dimensional tolerance. This can effectively reduce the gas pressure of the oil cylinder. The appearance of cavitation, but if the cavitation has occurred in the oil cylinder, it must be polished with metallographic sandpaper to remove pits and carbon ash accumulated on the surface due to cavitation. Remember, you must not Use ordinary fine sandpaper for sanding.
2. When repairing the oil cylinder, you must first completely eliminate the internal gas, and then you should allow the oil cylinder to run smoothly for a period of time, mainly to allow the hydraulic oil in the oil cylinder to fully circulate. If necessary, you can The oil pipe in the oil cylinder is directly disassembled, so that the hydraulic oil can overflow completely, mainly to completely exhaust the gas.
3. Strictly grasp the selection criteria of hydraulic oil in the oil cylinder. Selecting a hydraulic oil of good quality can prevent air bubbles from appearing during the work of the oil cylinder. When we choose a hydraulic oil, we should also consider the environment and temperature. The second is to ensure that the entire cylinder is clean, and the oil quality of the hydraulic oil needs to be checked regularly.
Fourth, the system to prevent the oil temperature of the cylinder is too high, to reduce the impact of hydraulic pressure and heat dissipation system, if there is any abnormal phenomenon in the work process, you should immediately stop working and find out the cause, and promptly eliminate the problem. When operating with the distribution valve, do not use too much force, and the speed should not be too fast, and the throttle of the engine must not be opened more frequently. The impact of the hydraulic cylinder on the hydraulic components should be minimized.
The above is the introduction of the cavitation treatment method of the spiral swing oil cylinder. I hope it will be helpful to you.
