(Summary description)Rejecting the secondary pollution of products handled by vacuum plasma cleaners should standardize this operation: During the use of the vacuum plasma cleaner, the product was contaminated by oil. What caused it? In fact, with regard to the secondary contamination of the product during the treatment process, it is likely that the following operation is not standardized. In other words, after the plasma cleaning equipment alarms, part of the oil and gas generated by the vacuum pump is sucked back into the vacuum chamber due to improper operation of the equipment. Have you ever made such a mistake during the operation? Let's continue to watch. Improper operation mainly means that when the plasma equipment fails and stops, the operator does not perform the operation of breaking the vacuum and starting the vacuum pump in a timely and standardized manner, but directly clicks the start button on the automatic interface. At this time, if there is residual oil and gas at the end of the vacuum pump, it will be sucked back into the indoor vacuum under the action of the negative pressure of the indoor vacuum, causing the pollution of the vacuum products. Since the vacuum plasma cleaner will automatically close its high-vacuum flapper valve after the alarm is stopped, but the vacuum chamber is still in a high-vacuum state at this time, and the high-vacuum to the vacuum pump end is in a normal pressure state, there is a pressure difference, if this Press the start button for a moment, the high-vacuum pneumatic baffle valve will open, and the oil and gas will be sucked backwards, contaminating the vacuum chamber, and then contaminating the product. Therefore, how should we perform correct and standardized operations when equipment alarms and shutdowns occur? When the vacuum plasma cleaner has an alarm and shutdown, the vacuum breaking action should be carried out in time at this time to confirm whether the vacuum pump has stopped due to the alarm. If the vacuum pump stops, you need to start the vacuum pump before you can continue to use it. The interlock function of the control circuit has been added. This method fully considers the mobility of the operator and the execution of the operating procedures and other factors, and optimizes the equipment control. Improved the interlocking function between the start of the vacuum pump and the start of the high-vacuum baffle valve, which can ensure that the vacuum pump will not open when the high-vacuum pneumatic baffle valve is not started, thereby preventing misoperation from returning oil to the vacuum chamber. The above are two relatively simple and practical methods of prevention and transformation, which are simple, effective, safe and reliable. However, in order to ensure product quality, it is still necessary to standardize the operation process of vacuum plasma cleaning equipment, that is, when the equipment fails and shuts down, it should be entered in time The manual interface performs the vacuum breaking action, because if the equipment is down for a long time, the product is always in a high vacuum state, and the indoor vacuum will also affect the processing effect of the vacuum plasma cleaner on the product.
