There are many hydraulic components on construction machinery, and sufficient hydraulic oil is required. When the hydraulic oil needs to be replaced due to its deterioration after a long time of use, some people mistakenly believe that it is only necessary to drain the oil in the hydraulic cylinder Sichuan Hydraulic cylinder Top up with new hydraulic oil. However, there are still many old hydraulic oils left in the hydraulic oil pipe and hydraulic control valve at this time. When the equipment is used, the mixing of new and old oils will speed up the deterioration of new oils. The correct oil change procedure should first drain the hydraulic oil in the hydraulic cylinder, clean the hydraulic cylinder, and then add new hydraulic oil, Sichuan Hydraulic cylinder Price Then remove the circuit header, start the engine and run at low speed to make the oil pump work and operate each mechanism separately.
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, Sichuan Hydraulic 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, Sichuan Hydraulic cylinder Price 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 Sichuan 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 Sichuan Hydraulic cylinder Price 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 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 Sichuan Hydraulic cylinder Price 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, Sichuan Hydraulic 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.
It is suitable for hydraulic transmission of construction machinery, lifting, transportation machinery and mining machinery. Hydraulic transmission principle - oil is used as working medium, Sichuan Hydraulic 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 Sichuan Hydraulic cylinder Price Flow rate and flow direction. For example: pressure control valve, flow control valve.
