对于真空镀膜机来说,真空泵是其获得真空环境不可缺少的一部分,制造商制造的每台涂布机都配有一种或多种真空泵。今天小编将告诉你如何为真空镀膜机选择真空泵。

一、选择真空泵时,首先要注意真空泵在工作时产生的振动对工艺和环境是否有影响如果工艺受到影响,应采取防振措施或选择另一台真空泵。在选择时,你需要知道待抽气体的成分,如果需要选择性抽气,一台泵可能不足以满足要求,必须组合多种不同的泵才能一起工作,如果镀膜机镀膜要求无油则应该选择无油泵。

二、真空泵的价格和维修费用也是我们考虑的重点之一。

三、镀膜机对真空度的极限要求和工作压力强度的要求越来越高,真空泵的抽真空能力要求越高,至少泵的极限真空度比真空设备的工作真空度高半个数量级以上。

四、每种泵都有一定的工作压强范围,例如像扩散泵的压力为3~10-7hhHg,其稳定工作压强范围为5*10-4~5*10-6mmHg,那么使用扩散泵就不能让其在未定工作压强范围之外工作。

五、当泵所需的气体压力不高或所需的真空度不高时,可以先选择单级泵,对排气压力或真空度的要求比较高,单级泵往往达不到要求,可以选择使用双级泵或多级泵。

能为自己的真空镀膜机选配合适生产需求的的真空泵是最机智的选择,希望大家能通过以上的分享能帮助大家选配到合适的真空泵。
