Large air separation plant KDON-16000/35000 solution for metallurgical industry
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
Small air separation plant KDON (Ar)-4000/4000-110 solution for metallurgical industry
Metallurgical industry is an industry that exploits metal mineral resources and produces raw materials of various metal products, which is closely related to the national economy and people's livelihood. At present, Chinese iron and steel industry still has the situation of low concentration, insufficient capacity of high-end products and serious surplus of low-end products. DEAR air separation has provided a number of complete solutions for the metallurgical industry for many years, accumulated rich experience and helped the efficient development of the metallurgical industry. With years of service experience in the metallurgical industry, the small air separation plant KDON (Ar) - 4000 / 4000-110 cooperated by DEAR air separation and customers provides air separation plant with mature technology, stable equipment working condition, excellent performance and energy saving intelligence, which is highly recognized by customers.

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 ...
