Deterioration of the inner wall of the cylinder surface roughness of Texas Lung of hydraulic cylinders, hydraulic cylinders increase friction, easy to produce creeping phenomenon. ③ increase the internal leakage of the hydraulic cylinder, the hydraulic cylinder work efficiency is lowered. The main cause of the cylinder bore surface scratches as follows. In order to ensure the normal operation of hydraulic equipment working professional production, must ensure that: 1, strict and careful installation; 2, cleaning equipment remaining in putty and impurities; 3, oil change, improve equipment lubrication systems. 4, more shift Xiao, make sure to clean the iron rails effective hydraulic Texas _ Long Hydraulic (certified) _ hydraulic cylinders supplied by Dezhou City, Long force hydraulic machinery plant.
