What is a cryogenic fast line
- Equipment is compressor, heat exchanger and expander (or throttle). The compressor and expander generally use a reciprocating or turbine. Commonly used heat exchanger coil type, shell and tube type or plate heat exchanger. Deep freezing technology, can the nature of the study of materials near absolute zero, and can be used for the separation of liquid and gas mixture of gases.
Industry can get liquid oxygen, liquid, gas, etc.; Can be effectively separated from the airs
What is the meaning of cryogenic technology in the mechanical process, what is the specific practice?
- High speed steel W18Cr4V cryogenic hardness, impact toughness and wear resistance are significantly improved with the use of its manufacturing tool life increased by 2~5 timess
I would like to ask how the process of cryogenic treatment
- Biology: fast cooling, can prevent the crystallization of cells in the water, does not destroy the cell organization. In the preservation of sperm, organ preservation, food preservation, preservation of certain life and so onMedical treatment: cryotherapy, treatment of certain skin diseasesSpace: the space environment simulation, satellite ground test station, using liquid helium, create -200 degrees of low temperature.Noise: high sensitivity radar telescope, using liquid helium cooling, receiving device, noise reductionVacuum: the use of cold well technology can get high vacuums
What is the meaning of deep frozen
- In general, the frozen layer of our home refrigerator can only reach -18 degrees, but also slow freezing, slow freezing will have a great impact on food nutrition and flavor.s
Ultra low pressure casting mold useful, how to arrange the process? Thank you
- The size stability of die casting die is mainly solved by the following aspects:1, in the die casting process and mold temperature stability under the premise of the mold size! To ensure product size!2, in the design of die casting products, according to the way the product and the simulation of the temperature field, the type of product, the direction of contraction and so on to develop the contraction ratio, the general product shrinkage rate of about 5/1000! Step by step cumulative experience!3, die casting mold in the production period of time, (for example, 5 thousand to 10 thousand times), can do stress treatment, ABP treatment, etc.! In order to reduce the internal stress in the production process of the mould, it can achieve the purpose of stabilizing the size, preventing the fracture and increasing the service life of the die!Want to help you!s
Who has a deep understanding of the cryogenic box
- 1, the principle of liquid nitrogen refrigeration: storage of liquid nitrogen in the container through the liquid in the sublimation of heat to take away the heat of the workpiece heat. Liquid nitrogen refrigeration can not be reused after the need to add a new liquid nitrogen, a large range of cooling rate, cooling temperature range of 0-196 degrees C.s
Cryogenic treatment to improve what performance?
- Improve the impact toughness of the workpiece;Improve the internal stress distribution and improve the fatigue strength;Improve the corrosion resistance of the workpiece;s
