The Hangzhou-Hangzhou Oxygen Co., Ltd. recently won the bid for the coal chemical project of the Henan Zhongyuan Dahua Group Co., Ltd.—the 50000-ton/year methanol engineering project with 52,000m3/h compression process air separation equipment. This is another breakthrough for the company in the design and manufacture of extra large air separation units following the signing of two contracts for the supply of 48,000m3/h compressed air separation units with Sinopec at the end of last year. This equipment is the largest chemical type internal compression process air separation equipment that is self-contained and independently designed and manufactured in China. The air is used to pressurize and inflate the air into the lower tower to complete the oxygen-nitrogen double-pump compression process. The molecular sieve purifies the air, the structured packing is on the tower, and the argon is fully rectified. The oxygen pressure is high for users, and the nitrogen pressure is low. Many, large-scale features, choose the most secure and reliable and economic and reasonable process, with advanced design parameters and process technology, reliable operation of the entire device, mature technology, easy operation, low energy consumption, good security and so on. Since 1998, Hangyang took the lead in the development of air separation technology centered on structured packed packing and fully-refined argon. In 2000, it successfully designed and manufactured the first domestic 16,000m3/h compressed air with complete independent intellectual property rights. Sub-equipment. After years of hard work, Hangyang has matured in the design and manufacturing technology of air separation equipment, not only consolidating its position in the domestic mid-end product market, but also gradually involved in high-end products, and began to compete with large international companies. The winning bid was for Hangzhou Oxy to take the lead in the competition with large companies at home and abroad.

Rotary punching is a brand new technology of punching plate with high efficiency,energy and material saving.There are main advantages of it:

Firstly, the machine has high speed, which can reach to 100m/min.The rotary Punching Machine has higher effiency than traditional mechanical punching maching.

Secondly, the machine can offer unified and repeated punching pattern.

Thirdly, it adopts the rolling technology of low noise and no vibration.There is only the sound of the motor.

Last but not the least, the mould can be used for a longer time than traditional punching machine because of the processing technology.
