The reason for the existence of cryogenic refrigerator in the tool parts manufacturing industry
Cryogenic treatment is applied to worn tools, die cutter materials, and later extended to alloy steel, cemented carbide, etc., this method can change the internal structure of metal materials, thereby improving the mechanical and processing properties of the material, it is currently One of the toughening treatment processes. The cryogenic cryostat can cause obvious changes in the structure, effectively promote the transformation of retained austenite to martensite and the precipitation of u...

Chemical reaction exothermic or endothermic temperature dynamic compensation system
In the chemical laboratory, pilot plant and reaction process, temperature control requires the use of dynamic temperature control systems. When controlling the reactor, the exothermic and endothermic reactions must be compensated with high speed and reliability. The dynamic compensation of exothermic or endothermic chemical reactions poses a greater challenge to temperature control systems. Especially if the reaction occurs in an extreme temperature range, the temperature control system must ...

Rotary shaft freezing process in new energy automobile motor assembly
As the market for new energy vehicles has gradually expanded, the new energy motor manufacturing industry has also grown. Then, for the motor manufacturer, the rotor into the core process during the motor assembly process is particularly important, which determines whether the shaft will bend during operation, which affects the service life of the motor. When the motor is used for the shaft and rotor set, the rotor and the shaft are generally used with a large interference fit. When the rotor...

Temperature control system for controlling integrated circuit chip test temperature
Advances in semiconductor technology have led to the development of next-generation electronic devices such as integrated circuits, which have more and more active components, higher circuit complexity, smaller area, and tighter wiring. These attributes generate more heat in the electronic device and provide fewer opportunities for heat dissipation. This results in higher operating temperatures and therefore reduces reliability, especially for integrated circuits operating at high frequencies...

Where do you need low temperature chiller and introduction
Even though water is one of the most precious and scarce resources, it is still used as a coolant in many laboratories. Unfortunately, most of the water used as a coolant is not recycled, resulting in higher and higher laboratory costs and wasted precious natural resources.LNEYA offers 10 models of the FL series with a temperature range of -15°C ~ 30°C and a cooling capacity from 760W to 5000W, which can meet all the needs of the laboratory. LNEYA incorporates self-diagnostic functions when d...
