Maintenance of pneumatic components
1: Maintenance work can be divided into regular maintenance work and regular maintenance work. The former refers to maintenance work that must be carried out every day, while the latter can be maintenance work carried out weekly, monthly or quarterly. Maintenance work should be recorded. Maintenance work should be recorded to facilitate future fault diagnosis and processing.
2: When checking for air leakage, methods such as applying soap liquid to each check point should be used, because the effect of showing air leakage is more sensitive than listening to the sound.
3: The cylinder piston rod is often exposed. Observe whether the piston rod is scratched, corroded or eccentrically worn. Based on whether there is air leakage, the contact between the piston rod and the guide bush in the front cover, the sealing ring, the processing quality of the compressed air, whether there is a lateral load on the cylinder, etc. can be judged.
4: Like safety valves, emergency switch valves, etc., die-casting molds are rarely used. During regular inspections, their operational reliability must be confirmed.
5: Let the solenoid valve switch repeatedly. From the switching sound, you can judge whether the valve is working normally. For AC solenoid valves, if there is a buzzing sound, it should be considered that the moving iron core and the static iron core are not completely attracted, there is dust on the attracting surface, the magnetic ring is detached or damaged, etc.
