Pay attention to when choosing pressure gauge:1) determine the range of pressure gauge. When the tested pressure is relatively stable, make 1/3 of the...
The common failure of thermocouple thermometer is that the indicating value is low, or it stops at zero. This is because of the problem caused by ther...
Air is a mixed gas, and the gas separation process cannot be carried out spontaneously. In order to realize the separation of oxygen and nitrogen, wor...
When the air volume decreases, both the rising steam volume and the recirculation fluid volume in the tower decrease, but the recirculation ratio can ...
In boiling water when we can see, at atmospheric pressure, temperature to 100 ℃, water began to boil. But water not all at once into steam, but with t...
The liquefaction temperature of gas is not only related to the type of gas, but also to the level of pressure. The higher the pressure is. The closer ...
There are different opinions on whether liquid oxygen explosion-proof system should be set in the air separation plant of molecular sieve purification...
In front of the molecular sieve purifier, in order to reduce the temperature when the processed air enters the purifier, the whole low pressure oxygen...
After the distillation column is started, the main possible reasons why the high pressure does not rise to the designed value are:1) insufficient proc...
The liquefaction unit is divided into low pressure liquefaction cycle and medium pressure liquefaction cycle, and the circulation medium can be air or...
This is because the temperature in the air separation tower in the start-up phase is away from the normal working temperature (-172 ~ -194 ℃) is relat...
When the air separation Tower turns from normal temperature to low temperature, the phenomena such as pipe crack and valve jam often appear. The main ...
