In daily use, the maintenance of pneumatic butterfly valves is also a big problem that cannot be ignored. So do you know where the focus of the maintenance of pneumatic butterfly valves is?
When the chassis of the car sinks and the car body becomes low, there are usually several reasons: First, the metal fatigue of the ball valve reduces the recovery ability of the ball valve; The second is caused by wear, deformation and oil leakage of buffer cylinder and other parts; Third, it is caused by the aging of hydraulic oil; Fourth, it is caused by aging oil seal and oil leakage. One of the important reasons for oil leakage is that the pneumatic butterfly valve core is damaged or rusted. Therefore, when the car falls and is impacted by external force, it is necessary to timely check whether the pneumatic butterfly valve core is deformed and whether the oil seal is damaged. This requires that whether the pneumatic butterfly valve core is damaged and rusted should be the focus of daily maintenance. Also, pay attention to check the oil seal and dust cover of the pneumatic butterfly valve for oil leakage, or dust and dirt adhesion, and clean the pneumatic butterfly valve core and related parts in time to ensure that the pneumatic butterfly valve is free of oil leakage. If the pneumatic butterfly valve buffer cylinder is oxidized and rusted, it can be ground with metal abrasive to restore its smoothness. Also pay attention to check whether the front pneumatic butterfly valve core is scratched or rusted, because this is one of the important reasons for the damage of the pneumatic butterfly valve oil seal and the leakage of hydraulic oil. Check the connecting rod oil seal for hydraulic oil leakage. If there is any leakage, it must be replaced or repaired by a professional. The dirt on the connecting rod of the buffer cylinder must be cleaned with a soft cloth. If oxidation and rust have occurred, it should be immediately removed by polishing with metal abrasive. The connecting rod part of the rear wheel buffer cylinder should be checked for sediment, dirt accumulation, scratches, rust, etc. If there are any of the above conditions, it should be cleaned or repaired in a timely manner.
