Vacuum coating technology is an important branch of 2BV liquid ring vacuum pump application technology. It has been widely used in optics, electronics, energy development, physical and chemical instruments, construction machinery, packaging, civil products, appearance science and scientific research. The main methods of vacuum coating are evaporation plating, sputtering plating, ion plating, beam stacking plating and molecular beam epitaxy. Chemical vapor deposition is also used.
If the purpose of vacuum coating is to modify the physical and chemical properties of the animal surface, this technology is also an important part of the vacuum surface treatment technology. Now we will give a brief introduction to several main applications. First, in optics, a piece of optical glass or quartz coated with a layer or several layers of different substances on the surface of the film, can become a high reflection or no reflection (i.e. anti-reflective film) or make any expected proportion of reflection or transmission data, can also be used as an absorption of a certain wavelength, and the transmission of another wavelength filter.
High reflective coatings are needed from the start of large-aperture astronomical telescopes and lasers to coated jasmines for large windows in new buildings. Antireflective coatings are widely used in photography and in the beginning of various lasers, as well as in coated glass for large windows of new buildings. Antireflection coatings are widely used in cameras and television cameras. Vacuum coatings play an important role in electronics. A range of inheritance circuits. Including the memory, the arithmetic unit, the notification logic element and so on all need to use the conductive film, the insulation film and the maintenance membrane. Chromium films are used as mask for making circuits.
1. Coaxial direct connection design saves space and is easy to install.
2. the use of imported mechanical seals as a standard configuration.
3. All of them are equipped with cavitation protection pipe interface. If working under extreme pressure, opening the cavitation protection pipe interface (or connecting with the separator) can eliminate cavitation sound under the condition of guaranteeing the suction effect to the maximum extent, and protect the 2BV water ring vacuum pump.
4. Aluminum bronze impeller has high strength, durability, and improves the corrosion resistance of 2BV water ring vacuum pump. If the over-flow parts are made of stainless steel, they can work in more harsh environment.
5. The unique design of flexible exhaust port will not produce over-compression, which ensures that the 2BV liquid ring vacuum pump has the best efficiency in its performance range.
6. All Y2 series motors are adopted, with protection level IP54 and IP55.
7. All imported bearings NTN or NSK are adopted.
