They are mainly used to control the temperature and keep the equipment in normal operation. The following is the specific application of industrial chillers in the vacuum ...
2022-11-2331200In the electronic and electrical industry, high-frequency rectifier is a kind of rectifier with small volume, light weight and high efficiency. It is used in various precision surface treatment places such as electrolysis, experiment, oxidation, zinc plating, corrosion, etc.In general, during the operation of high-frequency rectifier, the c...
2022-11-2340600In industrial production, more advanced laser processing technology is gradually adopted. Laser processing can bring better production efficiency and more possibilities of personalized design for production. It is well known that lasers or related devices are prone to heat and scald after being used for a period of time. In order to avoid large los...
2022-11-23379001. The operating ambient temperature cannot be too high.In high temperature summer, it should be noted that the operating ambient temperature of the chiller should not be too high, which will cause an alarm of ultra-high room temperature and lead to failure of normal refrigeration. The operating ambient temperature of the chiller should not exceed ...
2022-11-2335900In winter, when the ambient temperature is below zero, in order to ensure the smooth winter of the chiller and avoid irreversible losses to the equipment caused by the low temperature environment, it is necessary to take antifreeze measures for the chiller equipment. So, how to take anti freezing measures for industrial chillers in winter?Since t...
2022-11-2334400According to the latest issue of Nature, a research team led by the School of Engineering of the University of Pennsylvania has invented a chip whose security and robustness exceed the existing quantum communication hardware. Their technology uses "quantum code" to communicate, doubling the quantum information space of lasers on any previous chip....
