Small liquid nitrogen machine
We all know that a liquid nitrogen generator is a simple plug-and-play liquid nitrogen device that combines helium compression and expansion for cryogenic cooling. Built-in oil-free air compressor, PSA pressure swing adsorption nitrogen generator, refrigerator, helium compressor and Dewar tank, and controlled by a color touch screen, one key can be fully automatic operation. Of course, we must also pay attention to some matters in the process of use, especially the safety precautions of the liquid nitrogen generator during the test run,
The liquid nitrogen generator must be under the command of a special person during the test run. The author must make all preparations for the relevant personnel before the test run. If any abnormality occurs during the test run, stop the test run immediately and check. After finding out the reason and dealing with it, continue the test drive.
Of course, the maintenance and safety of the liquid nitrogen generator. Safety precautions are also very important:
Cut off the power supply and hang the sign of deactivation before overhauling. Ensure that the workshop is ventilated and has sufficient oxygen content to prevent nitrogen from directly entering people's mouth and nose. When a fire is required, a fire permit must be obtained and approved according to regulations. When using cranes and other lifting appliances, there must be a special person instructed, the ropes should be fastened firmly, and the maintenance tools, dismantling, cleaning and replacement parts should be neatly arranged in the specified places and constructed in a civilized manner.
