Existence of vacuum furnace cooling system of LNEYA cooling heating system
High-temperature vacuum furnace refers to an industrial furnace heated by electric heating elements in a state close to a vacuum. High-temperature vacuum furnace is generally composed of furnace, electric heating device, vacuum system, sealed furnace shell, power supply system and temperature control system. Vacuum furnace cooling temperature control system is an important part of vacuum furnace. The cooling water path should be kept clear, otherwise the water temperature rise will constitute...

Uso di frigoriferi per il trattamento a freddo di parti meccaniche e confronto con l'azoto liquido
In the machinery manufacturing industry, the quality requirements for parts are very strict. In order to better improve the performance of machinery, improve product quality and life, a new technology-cryogenic treatment has been produced. During the cryogenic treatment, the retained austenite in the parts can be largely converted to martensite, which can enhance the wear resistance, strength, toughness and impact resistance of the parts materials, improve fatigue strength and eliminate Inter...

Introduction of distillation principle and temperature cycle control device
Distillation is a common method for purifying liquid substances and separating mixtures. The boiling point of the compound can also be measured by distillation, so it also has a certain significance for the identification of pure liquid organic compounds. The change of saturated vapor pressure of a substance at different temperatures is the basis of distillation separation. Heating the liquid to boiling makes the liquid into a vapor, and then the vapor is cooled and then condensed into a liqu...

The significance of temperature in IC testing
Every integrated circuit (IC) goes through two type of tests before it can be sold and used to build a product: the first is called a wafer test; the second is called final test. With the improvement of integrated circuit electrical test technology and requirements, some chip products have integrated temperature sensors, or through the voltage changes of some precision diodes linearly related to temperature changes, the current actual chip under test is calculated through a series of formulas...

How to solve the common faults of industrial circulating chillers?
For industrial circulating chillers, if they are always in a high-temperature operating state, a large amount of cold air will be seriously lost. After ensuring the sealing effect of the use environment, effective thermal insulation can be carried out for the industrial chiller in a timely manner to ensure that the industrial circulating chiller is in a stable operating state. Stable operating efficiency can increase the efficiency of lowering the temperature in the unit environment and reduc...
