Air separation training needs to learn, including air composition, basic principles of air separation, technical development of air separation process, air separation process flow, main technical indicators of air separation equipment, etc.
DEAR air separation has cooperated with customers in metallurgical industry domestic and abroad in many projects, and has rich project experience. DEAR has continuously invested in the research and development of large-scale air separation plant. In view of metallurgical industry, DEAR combined with the characteristic of this industry, develops high-efficiency energy-saving air separation plant, to meet the needs of large and medium customers. DEAR air separation uses the rapid development of internet technology to establish a remote monitoring system to collect real-time operation data of each air separation plant, and provides the best suggestions for users by using big data analysis.
Metallurgical industry is an industry to develop metal mineral resources and produce various kinds of raw materials for metal products. With the progress of science and technology, the metallurgical industry has new requirements for the process, process, management and application research and development of air separation plant. The air separation plant also has the following development trends: first, large-scale and cluster; second, the core technology is gradually localization; third, refinement, which needs to develop high-efficiency energy-saving technology for different application fields; fourth, highly automated and intelligent, reduce manual operation as far as possible, and gradually establish a remote monitoring system by using the rapid development of internet technology to collect in real time according to the operation data of air separation plant, using big data analysis to provide the best suggestions for users, etc. KDON (Ar) - 16000 / 35000, a large scale air separat
Almost all motors commonly used in the air separation plant are three-phase AC motors. Three-phase AC motor can be divided into asynchronous motor and synchronous motor. The rotating speed of the synchronous motor and the frequency of the power grid keep a strict relationship, namely:
N = 60f/P in the formula P -- magnetic pole logarithm; f -- grid frequency, the normal situation is 50Hz; n -- motor speed, r/min. For example, for two-pole (P = 1) synchronous motor, the synchronous speed is 3000r/min; for four-pole motor, P = 2, n = 1500r/min. While the rotating speed of asynchronous motor is always less than that of synchronous motor, and it generates rotating torque by its phase difference. Asynchronous motor is most widely used. It consists of a stator and a rotor, and has a stator and a rotor winding respectively. The stator winding is made of copper (aluminum) wire with outsourcing insulation. With the difference of rotor winding, asynchronous motor can be divided into squirrel ...
In the operation of air separation plant, in order to ensure the accuracy of DCS control system monitoring and the safety and stability of operation, it is necessary to do well of DCS system grounding.
