Laboratory instrumentation antifreeze measures

In winter, due to the cold weather, laboratory instruments are frozen due to improper protection. How do you prevent freezing? What are the antifreeze measures for laboratory instruments?

First, the laboratory in the selection of equipment, according to the type of instrument and intended installation location, proposed the instrument's insulation and antifreeze needs, and then submitted to the manufacturers to deal with. In some places in the north, there is a large temperature difference between day and night, and it can reach over 20 degrees at night. If the solution is chosen, the price/performance ratio is quite uneconomical.

Second, insulation materials insulation, that is, use of insulation materials to freeze the instrument or fear of frozen parts of the package. During the winter, inspections should be carried out and the sewage should be drained regularly to prevent the insulation of the packaging from being damaged.

Third, heat-related measures 1, steam heating measures that use the pipe steam heating insulation. Before steaming in winter, check whether the steam insulation pipe is open or blocked. 2, insulation protection box measures 3, electric heating belt measures: electric heating with heat insulation technology is a new type of energy directly converted into heat energy heating technology. Install insulation cables, wind the heat trace around the instrument, or stick it inside the instrument cabinet (but pay attention to the length of the heating cable used, to be economically modest)

Fourth, maintenance measures 1, installation measures reasonable choice of installation location: dry, no rain and snow dripping place. 2. Check-up measures When conditional, technical personnel and technical disposal shall be performed daily by a specialist to determine whether the insulation material is damaged or whether the steam pipeline is clogged. 3. Alarm measures Conditional sound and light alarm devices that can be installed with steam leakage or power-off status to facilitate the discovery and timely remediation of hidden dangers of heat preservation and antifreeze measures. 4. The patrol measures shall be conducted by the regional instrument maintenance responsible person at the scheduled inspection route. During the inspection, it is necessary to check whether the insulation pipeline valve is normal, whether the insulation box is normal, whether the hydrophobic device is normal, whether the insulation material packaging is in good condition, and whether the electric heating power supply components are normal.
