Service life and maintenance method of pneumatic system and its components

·How long the pneumatic system can work normally is a matter of great concern to users.

·The durability indexes of various pneumatic components are usually given. According to the durability index, the service time of a pneumatic system under normal use conditions can be roughly estimated. For example, if the durability of the solenoid valve is 10 million times, the durability of the cylinder is 3000 km, the cylinder stroke is 200 mm, the switching frequency of the valve controlled cylinder is 3 times per minute, and the working time is 20 hours per day, and the annual calculation is 250 working days, then the solenoid valve can be used for 11 years, and the cylinder can only be used for 8 years. Therefore, the service life of the valve controlled cylinder system is 8 years. Because many factors are not considered, this is the longest life estimation method. For example, the aging of rubber in various components, corrosion of metal parts, the quality of air source treatment, whether the routine maintenance work can be adhered to, etc., will directly affect the service life of the pneumatic system.

·The service life of various components in pneumatic system is quite different, such as directional valve, cylinder and other components with relative sliding parts, their service life is relatively short. However, many auxiliary components have longer relative life due to less movable parts.The service life of various filters mainly depends on the service life of the filter element, which is closely related to the air quality after air source treatment. Such as the emergency stop switch, which does not often act, to ensure the reliability of its action, it must be regularly maintained. Therefore, the maintenance cycle of the pneumatic system can only be determined according to the use frequency of the system, the importance of the pneumatic device and the status of routine and regular maintenance. It is generally overhauled once a year. IMG_4543

·Before maintenance, the use, working principle and internal parts movement of the component should be known in advance according to product samples and operation instructions. If necessary, refer to the maintenance manual. According to the fault type, it should be estimated which part of the problem is more before disassembly.

·During maintenance, the common problems in daily work should be solved thoroughly. For the components of important parts, components with frequent problems and components close to their service life, they should be replaced with a new one. The protective plug of the vent of the new component should be removed only when it is in use. In many components, only a small number of parts are damaged, such as sealing rings, springs, etc. in order to save money, only these parts can be replaced.
