我厂、所于七一年五月份曾为大连第一塑料厂研制一台抽气量为0.处公斤/时,工作真空度为0.1乇的五级水蒸汽喷射泵。 由于该泵小而真空度高,所以要求喷咀(材质为Icr18Ni9T)的加工精度高,这样就给加工带来了一定的困难。 为了更好地完成这项任务,我车间曾组织有关人员到外厂学习电 Our factory, in May of 1981, once worked for Dalian No. 1 Plastic Factory to develop a five-stage steam jet pump with an exhaust volume of 0. kg / h and working vacuum of 0.1 Torr. As the pump is small and the vacuum is high, so the requirements of nozzle (material for Icr18Ni9T) high precision machining, this gives the processing has brought some difficulties. In order to better accomplish this task, I workshop has organized personnel to learn from the outside plant
