ZF HYDRAULIC often experiences malfunctions during use due to seal wear, cylinder barrel wear, inner wall scratches, inner wall corrosion, piston or piston rod scratches, etc. The sealing performance of hydraulic equipment actuators directly affects the performance of the equipment, especially for larger hydraulic cylinders whose sealing performance is damaged. Repairing or replacing parts is difficult and costly.

 

 

The traditional repair method is to disassemble the damaged parts of the hydraulic cylinder and outsource the repair, or to perform brushing and surface scraping, but the repair cycle is long and the repair cost is high. The latest contemporary maintenance method is to use polymer composite materials. The excellent adhesion and good compressive strength of its material not only meet the production and use requirements under the above working conditions, but also have a simple and easy operation process, without thermal effects, and the coating thickness is not limited. At the same time, the superior oil and corrosion resistance and self-lubricating function of the coating itself ensure the wear resistance after repair, guarantee the normal production of the enterprise, and avoid the aggravation of equipment component damage.

 

The maintenance of oil change and unboxing of the engineering hydraulic cylinder at ZF HYDRAULIC assumes that after using the engineering cylinder for a period of time, there will definitely be a large amount of foreign objects entering the interior of the cylinder. Therefore, when we use it again, there will definitely be severe friction because foreign objects enter the interior of the engineering cylinder, and as the number of foreign objects increases, the corresponding friction force will also increase, which will seriously affect the effectiveness of the entire engineering cylinder in use; Because hydraulic cylinders are also limited in their overall use, for some larger machinery, if the hydraulic cylinder is not replaced in a timely and effective manner after a long period of use, it can cause serious damage to the equipment and erode the internal structure of the entire engineering cylinder.
