As the core component of the cryogenic chamber, the compressor is the heart of its refrigeration system. Compressor oil is used on various types of machinery to reduce friction and protect the mechanical lubricants of liquids and workpieces. It is mainly used for lubrication, cooling, rust prevention, cleaning, sealing and buffering. The compressor oil must be replaced when it is used for a certain period of time. The correct oil change procedure for the high and low temperature chamber compressor is as follows: Step 1: Turn on and run to normal temperature for one hour; Step 2: Shut down; Step 3: Remove oil from the tank, cooler, and all filters. Step 4: Add the newly replaced oil to the minimum amount of oil required for operation (eg 1/2 volume); Step 5: Turn on and run to normal operating temperature for one hour. During this hour, the vent valve is opened and closed every 15 minutes to allow the machine to cycle at the highest pressure and lowest pressure valve settings; Step 6: Shut down; Step 7: Drain cooler, oil tank and all filters; Step 8: Add new replacement oil to 1/2 volume; Step 9: Continue to Step 5; Step 10: Shut down; Step 11: Remove the oil from the entire machine in the cryogenic chamber, including coolers, tanks, and filters. Remove tubing if necessary to remove low oil. Clean the filter, replace the separator and all non-permanent oil filters. Check the situation where the inlet filter is covered with contaminated oil and replace it as appropriate; Step 12: Add the recommended oil to be replaced to the minimum required for operation; Step 13: Turn on and run to normal temperature for 15 minutes; Step 14: Shut down and drain the machine. Open air filter and filter, but do not need to replace; Step 15: Add oil to the machine to normal oil level; Step 16: Reboot and note the oil level. When the machine is operating, there will be about 1/2 oil in the observation window; Step 17: Foam can be dispersed to the oil level within 2 minutes after shutting down and no oil flows out of the drain valve. Generally speaking, following this step, it is basically safe and secure. Have you learned it?
