The two lips of the seal have two contact circumferential surfaces. Whether the force on the inner and outer circumferences is evenly distributed means that the force on the two circumferences cannot be zero. If the force on a certain point is zero, the shaft seal has inner and outer lips, Shaoxing Hydraulic cylinder The outer lip is installed in the groove to contact the outer wall, and the inner lip is in contact with the piston rod surface. Both lips have an interference amount, which is equal to the generation of two contact circumferential surfaces, that is, the generation of two circumferential rebound forces. How to determine the magnitude of the circumferential force? Both the inner and outer lips of the seal have two chamfers. Since the interference of the same inner and outer lips is certain, Shaoxing Hydraulic cylinder manufactor The angle of the chamfer determines the size of the circumferential area of the inner and outer contact of the two lips.

Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, Shaoxing Hydraulic cylinder The high-pressure oil in the circuit will be ejected rapidly. When the hydraulic circuit is depressurized, first loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil, and then cut off the power supply or power source to stop the hydraulic device. During unloading, prevent damage to the thread at the top of the piston rod, the thread at the oil port, the surface of the piston rod, the inner wall of the cylinder liner, etc. Shaoxing Hydraulic cylinder manufactor In order to prevent the piston rod and other slender parts from bending or deformation, the skid shall be used to support and balance during placement.

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 Shaoxing Hydraulic 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 Shaoxing Hydraulic 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.

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. Shaoxing Hydraulic cylinder Therefore, when installing the hydraulic cylinder, the axis position of the cylinder must be consistent with the movement direction; Shaoxing Hydraulic 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.
