The valve core of the flow valve in the hydraulic cylinder is blocked, which is easy to cause the action failure of the hydraulic cylinder. We need to check whether there are pollutants in the oil in the hydraulic cylinder and whether the valve body is worn. It is necessary to check whether the piston rod seal is too tight, Zhuhai Hydraulic cylinder Whether there are pollutants entering, whether the axis line is aligned, and whether the easily damaged components fail. If the pressure controlled by the hydraulic system is too low, the action of the hydraulic cylinder will also fail, Zhuhai Hydraulic cylinder Manufacturer At this time, it is necessary to check the control pressure source to ensure that the pressure value is consistent with the specified value of the system.

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

Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, Zhuhai 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. Zhuhai Hydraulic cylinder Manufacturer 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 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, Zhuhai Hydraulic 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, Zhuhai Hydraulic cylinder Manufacturer In the whole process, the hydraulic cylinder converts hydraulic energy into mechanical energy.

For the selection of hydraulic cylinder, the hydraulic cylinder will be selected according to the inner diameter, stroke, operating pressure and installation type during the selection of hydraulic cylinder. In fact, in addition to these, we should pay attention to the following points. First, when the hydraulic cylinder is loaded and then the actuating speed reaches a certain standard, Zhuhai Hydraulic cylinder Hydraulic cylinder with buffer device must be used. Or when the speed reaches a higher speed, a deceleration valve must be installed outside the hydraulic cylinder; Secondly, carefully select hydraulic oil and oil seal. Oil seals of different materials are selected for different hydraulic oils, Zhuhai Hydraulic cylinder Manufacturer To ensure the service life of the hydraulic cylinder.
