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, Zhangjiajie Hydraulic station 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, Zhangjiajie Hydraulic station Manufacturer In the whole process, the hydraulic cylinder converts hydraulic energy into mechanical energy.
If the piston rod of the hydraulic cylinder is not treated in time after being pulled, the normal use will be affected if it is light, and the operation will not be possible if it is heavy. The repair methods we adopt are local polishing to repair light draw marks, welding and manual polishing to repair heavy draw marks. Zhangjiajie Hydraulic station Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Zhangjiajie Hydraulic station Manufacturer The purpose of surface hardening is to obtain high surface hardness to support the chromium plating layer on the surface, so as to improve the wear resistance and corrosion resistance of the piston rod.
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, Zhangjiajie Hydraulic station 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, Zhangjiajie Hydraulic station 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.
It is suitable for hydraulic transmission of construction machinery, lifting, transportation machinery and mining machinery. Hydraulic transmission principle - oil is used as working medium, Zhangjiajie Hydraulic station The movement is transmitted through the change of sealing volume, and the power is transmitted through the pressure inside the oil. 1. Power part - converts mechanical energy of prime mover into pressure energy (hydraulic energy) of oil. For example: hydraulic pump. 2. Executive part - converts the oil pressure energy input by the hydraulic pump into the mechanical energy driving the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3. Control part - used to control and adjust the oil pressure Zhangjiajie Hydraulic station Manufacturer Flow rate and flow direction. For example: pressure control valve, flow control valve.
