Select the cylinder type correctly according to the working requirements and conditions. It is required that there is no impact phenomenon and impact noise when the cylinder reaches the end of the stroke; Cushion cylinder shall be selected; Light weight is required; It is required to select light cylinder; Zhaoqing Hydraulic station Narrow installation space and short stroke are required; It is required to select thin cylinder; It is required to have transverse load, and the cylinder with guide rod can be selected; High braking accuracy is required, and locking cylinder can be selected; It is not allowed to rotate the piston rod, and the cylinder with rod non rotation function can be selected; Zhaoqing Hydraulic station manufactor In corrosive environment, corrosion-resistant steel cylinders shall be selected.
Because the hydraulic cylinder must bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is the most important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system. It is difficult to repair a heart problem, so the maintenance of the hydraulic cylinder should be careful. first, Zhaoqing Hydraulic station Rust prevention is required. Because the piston part of the hydraulic cylinder will extend out of the cylinder in the working state, it will naturally suffer from oxidation Zhaoqing Hydraulic station manufactor The erosion of acid gas requires us to apply proper amount of grease to protect it.
It is suitable for hydraulic transmission of construction machinery, lifting, transportation machinery and mining machinery. Hydraulic transmission principle - oil is used as working medium, Zhaoqing 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 Zhaoqing Hydraulic station manufactor Flow rate and flow direction. For example: pressure control valve, flow control valve.
As the structure and size of various hydraulic cylinders are different, the disassembly sequence is slightly different. Generally, drain the oil in the two chambers of the oil cylinder, remove the cylinder head, and finally remove the piston and piston rod. Zhaoqing Hydraulic station When disassembling the cylinder head of the hydraulic cylinder, special tools shall be used for the key or snap ring of the internal key type connection, and flat shovel is prohibited; Flange end caps must be pushed out with screws, and hammering or hard prying is not allowed. When it is difficult to draw out the piston and piston rod, do not force them out, Zhaoqing Hydraulic station manufactor The reason shall be found out before disassembly. Before and after unloading, try to create conditions to prevent the parts of the hydraulic cylinder from being polluted by the surrounding dust and impurities.
Items to be checked when the speed of hydraulic cylinder slows down. 1. Where and what type of oil cylinder has been used for several years, Zhaoqing Hydraulic station What is the working pressure. You don't have any of these. How can I troubleshoot them for you. Check the lower seal if there is internal leakage. 2. It is likely that the internal working pressure of the oil cylinder has decreased. 3. Check whether the system is blocked, Zhaoqing Hydraulic station manufactor In addition, check whether the oil cylinder seal ring is damaged, and then check whether the piston rod is damaged. Basically, these aspects can identify the problem.
