Small air separation plant KDON (Ar)-6500/6500-180 solution for metallurgical industry
Metallurgical industry can be divided into ferrous metallurgical industry and non-ferrous metallurgical industry. Ferrous metallurgy mainly refers to the production of pig iron, steel and ferroalloy (such as ferrochrome, ferromanganese, etc.), and non-ferrous metallurgy refers to the production of all metals except the former. 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) - 6500 / 6500-180 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.
Small air separation plant KDON-6000 / 3200 solution for circular economy industry
Garbage classification, environmental protection and circular economy have been widely advocated in recent years. At present, Chinese lead-acid battery industry and waste battery recycling industry are undergoing profound changes. The integration of the upstream and downstream industry chain of lead-acid battery industry will become the future development trend. KDON-6000 / 3200, a small air separation plant cooperated by DEAR air separation and its customers, is applied in the circular economy industry to practice the green environmental protection, low consumption and high efficiency. Make a contribution to beautify the environment and realize the transformation of garbage into resources. The high-quality air separation plant provided by DEAR air separation has been praised by customers for making contribution to the rise of circular economy.

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 ...
