Cryogenic coolant circulation pump usage precautions
Cryogenic Coolant Circulation Pumps Because of the inherent uniformity of the temperature field resulting from their own circulatory system, more and more experiments are being applied to cryogenic coolant circulators. Hanno brand DL series of low-temperature coolant circulation pump air-cooled fully enclosed compressor cooling and microcomputer intelligent control system to provide low-temperature circulating cooling water (liquid) flow or low temperature water (liquid) flow to meet the cooling water and low temperature Liquid to cool or thermostat instruments, widely used in petroleum, chemical, pharmaceutical, life sciences, measurement, light industry, and scientific research and other fields. What are the precautions for using cryogenic coolant circulation pump? ã€1】 Before using the low-temperature coolant circulation pump should be added in the tank liquid medium (pure water, alcohol, antifreeze can be), the media should not have liquid level within the cooling coil and lower than the table 20mm is appropriate. ã€2】 Power: 220V50Hz, power supply should be greater than the total power of the instrument, the power supply must have a good "grounding" device; [3] to avoid acid and alkali substances into the tank corrosion coil and the liner. ã€4】 The instrument should be placed in a dry and ventilated place, no obstacles within 300mm around the instrument; ã€5】 Always observe the level of the tank surface, when the liquid level is too low, the liquid medium should be added in time ã€6】 When the low temperature coolant Circulation pump operating temperature is low, should be careful not to open the cover, hands do not enter the tank to prevent frostbite; [7] is used, all the switches placed in the closed state, cut off the power; [8] Liquid outside the loop, the customer Pay special attention to the firmness of the outlet tube connection and prevent it from falling off in case the liquid leaks out. ã€9】 The instrument should be regular cleaning, long time do not have to empty the tank of the media, and wipe clean to keep the work surface and the operation panel clean; (Cryogenic coolant circulation pump usage precautions)
