Why is the maintenance of pneumatic components important?

The central task of maintenance work is to ensure that the compressed air pneumatic system is supplied clean and dry, to ensure the tightness of the pneumatic system, to ensure the necessary lubrication, to ensure the oil mist lubricating the components, to ensure that the pneumatic components and systems get the specified working conditions (such as the use of pressure). , voltage, etc.) to ensure that the pneumatic actuator works.

The lubricator is recommended to use the oil replenishment specification once a week, and pay attention to reducing the oil amount. If the fuel consumption is too low, the oil droplet volume should be readjusted. After adjustment, the number of oil droplets is still decreasing or not dripping. Check that the oil mist injector inlet and outlet are not reversed. Check that the oil passages are not blocked and that the selected lubricator is of the correct size.

Why is Pneumatic Component Repair Important?

Monthly maintenance work is more discreet than daily and weekly maintenance, but it is still limited to what the external vibrating plate can inspect. The main contents are: carefully check for leaks everywhere, tighten loose screws and pipe joints, check the quality of air discharge from the reversing valve of the junction box, check the flexibility of the adjustment part, check the correctness of the indicators, check the solenoid valve The reliability of the switching action checks the quality of the piston rod, everything can be checked from the outside.

Maintenance work can be divided into regular maintenance work and regular maintenance work. The former refers to maintenance work that must be performed on a daily basis, while the latter can be weekly, monthly, or quarterly. Maintenance work shall be recorded. Maintenance work should be recorded to facilitate future fault diagnosis and handling.

Yantai Pneumatic Manufacturer recommends that checking for air leaks should be done with soap and other methods at all check points, as it shows that the effects of air leaks are more sensitive than listening to sound.

When checking the quality of the air discharged by the reversing valve, the following three aspects should be paid attention to: First, to understand whether the oil exhaust gas is suitable, the method is to put a clean white paper near the exhaust port of the reversing valve. After three to four cycles of work, if there is only one light spot white, the paper indicates that the lubrication is good. The second is to know whether there is condensed water exhaust, and the third is to know if there is a leaking exhaust port to exhaust. A small gas leak indicates early damage to the assembly (a slight leak from the gap seal valve is normal). If the lubrication is not good, the chemical pump should consider whether the installation position of Mr. Oil is suitable, whether the selected specifications are suitable, whether the dripping amount is properly adjusted, and whether the mass vibration vibration method meets the requirements. If there is a condensate drain, a filter should be considered. The location of the unit is appropriate, the actual and optional uses of the various water removal components are rationalized, and the management of condensate is compliant. The main cause of leakage is poor sealing in the valve or cylinder , and insufficient air pressure. This is a large leaking seal valve, it could be the spool, caused by a worn valve sleeve.

Cylinder piston rods are often exposed. Observe whether the piston rod is scratched, corroded, or unevenly worn. According to whether there is gas leakage, it can judge the contact between the piston rod and the guide sleeve of the front cover, the sealing ring, the processing quality of the compressed air, or whether the cylinder has lateral load, etc.
