The diameter of the oil unloading hole of the hydraulic cylinder is too large, which directly affects the service life of the rubber seal ring on the piston. Because the piston moves back and forth, Langfang Cylinder When the rubber seal ring on the piston passes through the oil discharge hole, the rubber's own elasticity expands to the oil discharge hole, and the oil discharge hole edge and the piston seal groove edge shear the rubber seal ring. At the same time, China has the advantages of strong market demand and low cost, and is expected to become the center of gravity of the world's hydraulic industry and oil cylinder industry in the future. The hydraulic cylinder is a very important part of the hydraulic machinery and plays an executive role in the entire hydraulic machinery, Langfang Cylinder manufactor In the whole process, the hydraulic cylinder converts hydraulic energy into mechanical energy.

The failure of the hydraulic cylinder due to improper design and manufacture is because the oil pressure cannot act on the effective working area of the piston when the piston travels to the end point and returns, or the effective working area is too small when starting, which causes problems. When the transverse load of the hydraulic cylinder is too large, the force is not strong or the cylinder is bitten, the same consequences will occur. Langfang Cylinder Therefore, when installing the hydraulic cylinder, the axis position of the cylinder must be consistent with the movement direction; Langfang Cylinder manufactor And ensure that the load borne by the hydraulic cylinder passes through the cylinder axis as far as possible without eccentricity, so that the problem can be solved.

The hydraulic cylinder is the actuating element that converts hydraulic energy into mechanical energy in the hydraulic system. The faults can be basically summarized as hydraulic cylinder misoperation Langfang Cylinder manufactor It is unable to push the load and the piston slips or crawls. It is not uncommon for hydraulic cylinder failure to cause equipment shutdown. Therefore, Langfang Cylinder Attention should be paid to the fault diagnosis, use and maintenance of hydraulic cylinder. The main reason for excessive wear of piston seals is that the speed control valve is improperly adjusted, resulting in excessive back pressure, improper installation of seals or contamination of hydraulic oil. Secondly, foreign matters enter during assembly and the quality of sealing materials is poor.

The hydraulic system is composed of various hydraulic components. All hydraulic components are organically connected into a complete hydraulic system by pipes, joints, integrated valve blocks and other parts. Therefore, whether the hydraulic pipeline is installed correctly Langfang Cylinder Firm, reliable and neat will have an important impact on the working performance of the hydraulic system. Check the quality of pipes. Find out the pipe material Langfang Cylinder manufactor Whether the size and quality meet the design requirements; Check whether there is serious flattening or bending on the appearance of the pipe, whether there is corrosion on the surface of the inner and outer walls of the pipe, whether there is crack on the outer wall and other defects.
