What Should Be Paid Attention To To Prolong The Service Life Of Hydraulic Cylinders?
Installation Preparations: Before installing the hydraulic cylinder, refer to the manual and order parameter information to ensure its compatibility with the hydraulic system. Clean the hydraulic cylinder and the surrounding environment, ensuring that the fuel tank is properly sealed. Remove any oxidized iron scale, dirt, or debris from the pipeline and fuel tank.
Selection of Sealing Accessories: The choice of sealing accessories, such as seals and gaskets, is vital for the performance and longevity of the hydraulic cylinder. Select accessories that provide reliable sealing, have a long service life, and minimize friction loss. Consider factors like material, shape, and compression to ensure optimal performance.
Secondary Machining of Pistons: Pistons are in constant contact with hydraulic oil and subjected to temperature and pressure changes. The surface friction coefficient of the piston significantly impacts the overall efficiency. After purchasing the piston, perform secondary machining, such as increasing coating thickness and post-plating polishing, to remove any defects, clean flash, and burrs. This enhances the surface friction characteristics of the piston.
Cavitation Prevention: Cavitation can cause erosion on the inner surfaces of the hydraulic cylinder, piston, and piston rod due to factors like poor oil quality or air bubbles in the oil. Preventing cavitation is crucial for maintaining the cylinder's integrity. Ensure strict control over the quality of hydraulic oil, selecting oil that meets standards and is free from air bubbles. Design a cooling system that prevents localized high oil temperatures and reduces hydraulic shock. Maintain system stability and avoid excessively fast operations.
