一、概述随着空间技术的发展,受控热核反应的研究、大型低压风洞真空校准装置的制造,提出了要有极大的抽速或极高真空度的真空获得设备。冷凝真空泵无论是真空度,还是抽速,都能满足这些装置的要求,冷凝泵,有人称其为低温泵或深冷泵。从我国普冷,深冷、低温的温度划分范围来分,称为冷凝泵还是比较确切的。冷凝泵是利用极低温度的气体或液体(一
I. Overview With the development of space technology, the controlled thermonuclear reaction research, the manufacture of large-scale low-pressure wind tunnel vacuum calibration device, a vacuum pumping device with great pumping speed or extremely high vacuum is proposed. Condenser vacuum pump, whether vacuum or pumping speed, can meet the requirements of these devices, condensate pump, some people call it a cryogenic pump or cryogenic pump. From China’s general cold, cold, cold temperature division of the range, known as the condensate pump or more exact. Condensate pump is the use of very low temperature gas or liquid (a
