(Summary description)As the saying goes, sharpening a knife never misses a woodcutter. Good use of a good tool can often make the work more effective. Of course, the machine is also good to maintain, so below to share some of the vacuum plasma cleaning machine maintenance matters. Vacuum plasma cleaning machine maintenance: Note: All relevant safety precautions should be taken prior to the commencement of cleaning machine maintenance or repair, not limited to the contents mentioned here. I. Premise Work: 1. Turn off the power switch of the equipment and disconnect the main power protector. 2. Shut off all gas. 3. Prepare the necessary toolbox. Ii. Maintenance of vacuum chamber and vacuum generating system: 1. The vacuum cavity and the electric plate are the working areas of the workpiece. After being used for a certain period of time, some dirt will remain in the cavity and adhere to the electric plate and the wall of the cavity. Treatment method: After continuous use for one month, clean all electric plates and cavity walls with dust-free cloth (paper) dipped in alcohol to keep the cavity clean. 2. The observation window is used by the staff to observe the discharge in the cavity during work. After using for a period of time, the surface of the observation window glass will be slightly corroded, making it blurred. Treatment method: clean the glass with dust-free cloth (paper) dipped in alcohol or acetone or replace the vacuum glass directly. 3. Vacuum pump used in oil for oil to prevent oxidation, change in time is beneficial to the normal work of the vacuum pump, prolong the service life of pump body, suggest changing once every three months, often should observe in the vacuum pump oil is enough, if the oil level of oil level gauge instructions below cut-off use (clearly marked) by the side of the oil level gauge, inject new oil to normal oil amount in time. Iii. Specific steps for replacing vacuum pump oil: 1. Open the oil plug of the refueling port of the vacuum pump (inner hexagon wrench); 2. Open the drain plug on the oil valve (pay attention to the direction of the knob switch); 3. Release the oil safely, and then the oil level in the oil level meter will drop; 4. Tighten the drain plug after cleaning the oil in the pump; 5. Pour the new oil into the filling port and add more than the minimum amount; 6. Tighten the oil filling plug with a hexagon wrench; Note: Please inject pure and special oil when replacing. Remove the original oil from the vacuum pump. Staff should wear rubber gloves and face masks when changing oil. Please dispose of the waste oil properly and safely. Vacuum pump exhaust outlet is connected with oil mist filter, oil mist filter can remove nearly 90% oil mist discharged from the vacuum pump, can prevent the pollution of the working environment, but also can play a silencing effect. The filtered oil must be expelled from the body through the oil return port, otherwise the oil will accumulate between the filter element and the body, which will lead to the formation of oil mist. 1. It is recommended to replace the filter elements every three months. 2. If there is no exhaust, check whether the filter element is blocked, and consider replacing the filter element if necessary. The plasma generator is a high-frequency device, which involves frequency drift and other problems. After use, it should be adjusted once every 2 years or so. The customer should determine the time to contact the manufacturer and return to the factory for correction and adjustment. The seal of the equipment should be replaced every 18 months or so, and then every 18 months to ensure the reliability of the vacuum seal. Iv. Specific maintenance items of vacuum plasma cleaning machine: 1. Check the vacuum pump oil regularly every month to check the oil level and purity of the vacuum pump oil, observe the oil level window, and add to the position between the upper and lower of the oil red line when the oil level is close to the lowest red line scale; Observe the color of the oil. The normal oil is clean and transparent. When the oil becomes turbid (the oil color becomes grayish brown or the oil level window is blurred) and the noise of the vacuum pump is abnormal, replace the vacuum oil in time. 2. Cleaning the reaction chamber: first, use defatted cotton cloth dipped in anhydrous ethanol (commonly known as alcohol) to wipe the vacuum chamber (do not wipe the reaction chamber with ethanol to observe the glass). Secondly, gas (argon + oxygen or nitrogen + oxygen) is introduced into the chamber to react with plasma to remove the residue in the chamber. The processing time should be around 10 minutes, at least once a month. Check the integrity of the gas pipeline and vacuum hermetically. Check the integrity of the vacuum system periodically. This should be done after a thorough cleaning of the reaction chamber to avoid contamination from missing i
