Mechanical causes of small air separation unit fin heat exchangers

Mechanical causes of small air separation unit fin heat exchangers
Plate and fin heat exchangers in actual operation will have a certain degree of fouling, corrosion and blockage problems, resulting in uneven distribution of logistics, due to the harsh operating environment, the heat exchanger will usually have a certain degree of tilt, received inertial forces and gravity double impact, the uneven distribution of logistics is significantly more serious than the horizontal state.

1500/100 Y-type solution for small air separation plant in new material industry
The new material industry system of our country has been initially formed and the development situation is good. With the introduction of national strategic planning such as "The development plan of national strategic emerging industries in the 13th Five-Year Plan" and "The development plan of new material industry in the 13th Five-Year PlanThe new material industry system of DEAR air separation has been initially formed and the development situation is good. With the introduction of national strategic planning such as "The development plan of national strategic emerging industries in the 13th Five-Years Plan" and "The development plan of new material industry in the 13th Five-Years Plan", it has created a good policy environment for the development of new material industry. Recently, DEAR air separation cooperated with clients on the 1500/100 Y-type project of small air separation plant. The overall design of the project is reasonable, and the one-time drive is successful, and all the
4500/4500-type solution for small and medium-sized air separation plant in nonferrous industry
According to the influence and reform of the general environment of the non-ferrous industry, the problems faced by this industry are becoming more and more serious, and the control of production capacity is particularly important. Recently, the 4500/4500 type small air separation equipment project signed with customers by DEAR Air Separation, through the trial run stage, all the technical indicators have reached or exceeded the design standard, and have been continuously sending nitrogen for several days, which has been well received by users.

Why is the cryogenic air separation air compression system the most power consuming link?
Mar 23, 2026
Screw compressor is a positive displacement compressor from the mechanical type, which is composed of the driving rotor and driven rotor, the main body and a pair of synchronous gears. Therefore, the common faults of screw compressor are as follows: 1. The bearing is burnt out. Because of the foreign matter in the oil system, the oil pressure and the quality of the oil are reduced, resulting in the bearing burning out. The main treatment methods are: check the oil supply system; clean the oil filter and the cooling pipe of the oil cooler; check and adjust the oil pressure regulating valve; test the oil quality, and replace the oil when it is not good; check and deal with the oil leakage points. 2. The rotor is burnt out. When foreign matters enter into the compressed medium system, the temperature of the rotor rises, the temperature of the cooling oil of the rotor increases due to the high temperature of the inhaled medium, and the compression ratio increases, which may cause the
