No matter what kind of mechanical equipment, daily maintenance is extremely important, and it can be standardized and institutionalized. Take the electric butterfly valve as an example. Such a wide range of products will inevitably affect their working efficiency if they are used for a long time, while routine maintenance can extend their service life. 　　　　

The pneumatic butterfly valve of the cylinder is the most internal and central part, which also needs regular inspection and maintenance. At ordinary times, it needs to do a good job on the surface of the cylinder. At the same time, it needs to add lubricating oil to the shaft circlip. The amount of lubricating oil added should not be too much, but it needs to be checked and added regularly. Generally, the top cover of the cylinder should be opened every half a year, and then check whether there are impurities and moisture in the cylinder, At the same time, check the amount of internal lubricating grease. If the lubricating grease has been used up or is about to be used up, the cylinder needs to be removed from the inside of the valve for comprehensive maintenance and cleaning, and then add lubricating grease. If the outside of the cylinder is not cleaned up, impurities will mix with the lubricating grease, causing the lubricating grease to lose its function.
