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. Liaoyuan Cylinder Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Liaoyuan Cylinder manufactor 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 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. Liaoyuan Cylinder Therefore, when installing the hydraulic cylinder, the axis position of the cylinder must be consistent with the movement direction; Liaoyuan 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.
It is suitable for hydraulic transmission of construction machinery, lifting, transportation machinery and mining machinery. Hydraulic transmission principle - oil is used as working medium, Liaoyuan Cylinder 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 Liaoyuan Cylinder manufactor Flow rate and flow direction. For example: pressure control valve, flow control valve.
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 Liaoyuan 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, Liaoyuan 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.
Because the hydraulic cylinder has to bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is an important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system, Liaoyuan Cylinder It is difficult to repair the heart problem, so the maintenance of the hydraulic cylinder should be careful. First, rust prevention. Because the piston part of the hydraulic cylinder will extend the cylinder in the working state, Liaoyuan Cylinder manufactor Naturally, it will be corroded by oxide and acid gas, which requires us to coat it with proper grease for protection.
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 Liaoyuan 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 Liaoyuan 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.
