Classification Criteria for Vacuum Bellows


The vacuum bellows refers to a tubular elastic sensor connected by a foldable wrinkle sheet in the direction of folding and expanding. Vacuum bellows are widely used in instruments and meters. The main use is as a measuring element of pressure measuring instruments, which converts pressure into displacement or force.

The classification criteria of vacuum bellows are as follows:
Vacuum bellows are divided according to molding methods: hydraulically formed vacuum bellows and hydraulically formed vacuum bellows
Vacuum bellows are divided into: seamless vacuum bellows and seamless vacuum bellows
Vacuum bellows are divided into elastic vacuum bellows and ordinary vacuum bellows according to the elastic coefficient.
Vacuum bellows are divided into: stainless steel vacuum bellows, bronze vacuum bellows, aluminum vacuum bellows and ceramic vacuum bellows

Explanation of Common Terms of Metal Bellows

1. Waveform     It is the shape of the wave after hydroforming, and it is the most basic element of the metal bellows. 2.O.D     Outside diameter of metal bellows 3.I.D     Inner diameter of metal bellows 4. Wave distance     Distance between two waves 5. Itinerary     Difference between free length and compressed length 6. Scaling     Stroke of metal bellows divided by free length of bellows 7. Vacuum     The degree of gas dilution in a vacuum state is usually expressed as "high vacuum" and "low vacuum". A high degree of vacuum means that the degree of vacuum is "good", and a low degree of vacuum means that the degree of vacuum is "bad". Torr is usually used as a unit, and Pa has been used internationally as a unit in recent years. 1 Torr = 1/760 atm = 1 mm Hg = 133.322 Pa (or 1 Pa = 7.5 x 10-3 Torr) 8. Service life   ...

Brief Introduction of Infrared Gas Analyzer

Gas industry terminology, the vibration and rotation spectra of most gas molecules are in the infrared band. When the frequency of the incident infrared radiation is the same as the characteristic frequency of the vibrational rotation of the molecules, the infrared radiation will be absorbed by the gas molecules, causing the attenuation of the radiation intensity. An infrared gas analyzer made using the principle of absorption of infrared radiation by this gas molecule has the characteristics of high measurement accuracy, fast speed, and continuous measurement. In the industrial departments of iron and steel, petrochemicals, fertilizers, machinery, etc, instrument is an important monitoring method for production process control; it also has many successful applications in environmental pollution component detection and medical physiology research.  This product is used in: Optimized operation of small combustion systems For combustion systems using all types of fuels (oil, ...

Battery Injection Glove Box Antechamber

图片
  The liquid-filled glove box antechamber is an important link that needs to be isolated and transported out of the glove box after being packaged into the glove box for electrolyte injection and vacuum sealing once during the production of lithium polymer soft-pack batteries. There are strict technical requirements for the gas environment in the glove box, the air pressure, temperature, and dryness in the glove box when the electrolyte is injected and the vacuum is sealed once.         The existing cylindrical antechamber is manually loosened and tightened, and the silo door is tightened frequently, the mechanical tooth bar is easy to wear, the operation is troublesome, and the efficiency is low;         The transition warehouse control program does not set the mutual induction function of the opening of the inner and outer sealed doors, and can open both the inner and outer doors at the same time. Th...
