SMC air source processor maintenance

The composition of the SMC air source processor includes an air filter, a pressure reducing valve, and an oil mist filter. The filtration degree is generally 50-75 μm, the pressure adjustment range is 0.5-10 Mpa, and the filtration accuracy is 5-10 μm, 10-20 μm, 25. - 40μm, and the pressure regulator for the 0.05-0.3Mpa, 0.05-1Mpa three large pieces of non-connected components called the three-piece.

1, the oil mist device is best to use a week oil replenishment specifications, pay, pay attention to reduce the amount of oil. If the fuel consumption is too low, the amount of oil drip should be readjusted. After the adjustment, the quantity of oil drip is still reduced or not drip. Check whether the luster inlet and outlet are reversed and whether the oil channel is blocked. What is the specification of the selected lubricator? Suitable.

2. Each quarter of the month's maintenance work should be more careful than the daily and weekly maintenance work, but it is still limited to the scope of the external inspection. The main contents are: carefully inspect leaks everywhere, tighten loose screws and pipe joints, check the quality of the air discharged from the reversing valve at the terminal block, check the flexibility of the adjustment parts, check the correctness of the indicator, check the solenoid valve The reliability of the switching action checks the quality of the cylinder rod and everything that can be checked from the outside.

3, maintenance work can be divided into regular maintenance work and regular maintenance work. The former refers to maintenance work that must be performed every day, and the latter can be weekly, monthly, or quarterly maintenance work. Maintenance work should be recorded. Maintenance work should be recorded to facilitate future fault diagnosis and handling.

4, check the air leakage should be used at all checkpoints and other methods to apply soap, because it shows the effect of air leakage is more sensitive than listening to sound.

5, check the quality of the air discharged from the reversing valve should pay attention to the following three aspects: First, to understand whether the oil contained in the exhaust is appropriate, the method is to put a clean white paper near the outlet of the reversing valve After the valve has worked for three to four cycles, if there is only a light spot on the white paper, indicating that the lubrication is good, the second is to understand whether there is condensate in the exhaust, and the third is to understand whether the exhaust port of the exhaust should be leaked. gas. A small amount of gas leakage indicates early damage to the component (a slight leak in the gap seal valve is normal). If the lubrication is poor, the chemical pump should consider whether the installation position of the lubricator is appropriate, whether the selected specifications are appropriate, whether the drip volume is adjusted properly and whether the management method meets the requirements. If the condensed water is discharged, the position of the filter should be considered. Appropriate, whether the actual and appropriate selection of various water removal components is reasonable, and whether the condensate management meets the requirements. The main cause of leakage is the poor sealing in the valve or in the cylinder and the lack of air pressure. This is a large leakage of the sealing valve, it may be the valve core, caused by wear of the valve sleeve.

6, the cylinder piston rod is often exposed outside. Observe whether the piston rod is scratched, corroded, and has uneven wear. According to whether or not there is a gas leak, it can be judged whether the guide sleeve in the piston rod and the front cover, the contact condition of the seal ring, the processing quality of the compressed air, or whether the cylinder has a lateral load or the like.

7, like the safety valve, emergency switch valve, die casting mold is rarely used. When checking regularly, you must confirm their operational reliability.

8, let the solenoid valve repeatedly switch from the sound can be judged whether the valve is working properly. For the AC solenoid valve, if there is a beep, it should be considered that the moving iron core and the static iron core are not completely sucked, dust is sucked on the suction surface, and the magnetic sub ring is detached or damaged.
