３６位节能灯圆排车技改探讨李静波（泗阳灯泡厂江苏省泗阳市２２３７００）１如何获得符合要求的真空度１．１增加气导由于节能灯排气管的长度远大于其内径，因而气导较低，灯管内部空间只能利用泵抽速的一小部分，靠增加泵的抽速来提高灯管内的真空度是不行的。因此在技... 36 energy-saving lamps round row technology research Li Jingbo (Siyang Bulb Factory, Siyang City, Jiangsu Province, 223700) 1 How to obtain the required degree of vacuum 1.1 increase gas guide As the energy-saving lamp exhaust pipe length is much larger than its inner diameter , So the air guide is low, the internal space of the lamp can only use a small part of the pumping speed, by increasing the pump pumping speed to improve the degree of vacuum within the tube is not acceptable. So in technology ...
