Airtac maintenance work can be divided into regular maintenance work and regular maintenance work
The maintenance of airtac pneumatic components and their devices is a long-term task. As an enterprise, if you can develop pneumatic components Standardized maintenance management and strict implementation can largely avoid premature damage or frequent failures and greatly extend the service life of pneumatic components. So what are the main issues that should be paid attention to in the correct use and maintenance of pneumatic components? Here is a brief overview.
The central task of maintenance work is to ensure the supply of clean and dry compressed air to the pneumatic system, ensure the air tightness of the pneumatic system, and ensure that the oil mist lubrication components are Necessary lubrication ensures that pneumatic components and systems receive specified working conditions (such as operating pressure, voltage, etc.) to ensure that pneumatic actuators work according to predetermined requirements.
It is best to use a lubricator that can be replenished once a week. When replenishing oil, pay attention to the decrease in oil volume. If the oil consumption is too low, the oil dripping amount should be readjusted. After adjustment, the oil dripping amount is still reduced or there is no oil dripping. You should check whether the inlet and outlet of the lubricator are installed backwards, whether the oil passage is blocked, and whether the specifications of the selected lubricator are correct. suitable.
Monthly and quarterly maintenance work should be more careful than daily and weekly maintenance work, but it is still limited to the scope of external inspection. The main contents are: carefully check the leakage everywhere, tighten the loose screws and pipe joints, check the quality of the air discharged from the reversing valve, check the flexibility of each adjustment part, check the correctness of the indicating instrument, and check the switching action of the solenoid valve. Reliability, check the quality of the cylinder piston rod and everything that 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 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.
When checking for air leaks, methods such as applying soap solution to each check point should be used, because the effect of showing air leaks is more sensitive than listening to sounds.
When checking the quality of air discharged from the reversing valve, attention should be paid to the following three aspects: First, understand whether the lubricating oil contained in the exhaust is appropriate. The method is: Place a piece of clean white paper near the exhaust port of the reversing valve. After the valve has been working for three to four cycles, if there are only very light spots on the white paper, it indicates that the lubrication is good. The second is to know whether the exhaust contains Condensation water, the third is to know whether there is air leakage in the exhaust port that should not be exhausted. A small amount of air leakage indicates early damage to the component (it is normal for the gap seal valve to have slight leakage). If the lubrication is poor, you should consider whether the installation position of the lubricator is appropriate, whether the selected specifications are appropriate, whether the oil dripping amount is adjusted reasonably and whether the management method meets the requirements. If there is condensed water discharge, you should consider whether the position of the filter is appropriate. Whether the actual and selection of various types of water removal components are reasonable, and whether the condensate water management meets the requirements. The main cause of leakage is poor sealing in the valve or cylinder, insufficient air pressure, etc. When the leakage of this sealing valve is large, it may be caused by wear of the valve core and valve sleeve.
