In daily use, the maintenance of pneumatic ball valve is also a big problem that cannot be ignored. So do you know where the focus of the maintenance of pneumatic ball valve 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 ball 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 ball valve core is deformed and whether the oil seal is damaged. This requires that whether the pneumatic ball valve core is damaged and rusted should be the focus of daily maintenance. Also, pay attention to check whether the oil seal and dust cover of the pneumatic ball valve have oil leakage, or whether there is dust and dirt attached, and clean the pneumatic ball valve core and related parts in time to ensure that the pneumatic ball valve has no oil leakage. If the buffer cylinder of the pneumatic ball valve is oxidized and rusted, the metal abrasive can be used for grinding to restore its smoothness. Also pay attention to check whether the front pneumatic ball valve core is scratched or rusted, because this is one of the important reasons for the damage of the pneumatic ball 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.
