Its purpose is to transfer cryogenic liquids from places with low pressure to places with high pressure.With the development of air separation technol
The cryogenic pump is different from general pump in that it keeps low temperature during the liquid transfer process and minimizes cold loss, otherwi
The following problems should be paid attention to in the structural design of cryogenic liquid pumps:
(1) To ensure uniform cold shrinkage of parts
When the centrifugal pump is working, depending on the pressure difference inside and outside the pump, the liquid is continuously sucked into the pum
For short, air separation is a process of separating oxygen and nitrogen from air by means of deep freezing, adsorption and membrane separation, or ex
The amount of liquid-air evaporation depends on the nitrogen content of the distillate. The higher the nitrogen content, the lower the evaporation. At
The expander is divided into pressurization end and expansion end. After emergency shutdown and planned shutdown, because the expansion end is in low
Three oil and two cloth is a kind of anti-corrosion method, which is generally used for direct buried anti-corrosion of buried pipelines. There are ma
In order to keep the frequency of power grid constant, the speed of steam turbine needs to be maintained in a certain range. The main valve opening of
1. The newly built air separation unit was fired on site when it was first filled with pearlite. A tube was directly sent to the top of the tower. It
Floating rate is an important index of water-saving performance of cooling tower. Large floating rate means more water consumption of cooling tower. T
1. Expansion air into the lower tower requires that the pressure of air out of the air compressor is much higher. 5 MPa (g), which is generally used i
