求助各位大神如果需要这么高的负压,真空泵组怎么选配罗茨泵搭配?

容器多大 温度多高 参数得给一下吧

300L的料缸,加热到268度,

不行你就直接用一个螺杆真空泵得了

你给的真空度换算成绝压的话大概是4kpa-10kpa,不知道你是否有给错?螺杆泵确实可以满足你这样的真空度;但是进气温度有200+,肯定要在泵前加冷却系统的。一般螺杆泵的进气温度要求是低于50度。另外如果要选泵的话你还需要提供一个抽速大小。

加热在料缸的夹套里面进行,这是负压呀,螺杆泵的型号怎么选?

搅拌內加热到268度,那么顶部温度多少呢?不大可能200度的。如果的确高,必须经过冷却。冷却后往复真空泵、罗茨、螺杆都可以的。一级不够的话,那么二级,看参数

建议你先去百度一下真空的基本知识,比如把绝压负压之类的弄清楚,然后找家螺杆泵的厂家咨询,这样对你的工作比较好开展。

顶部没设夹套加温,就是搅拌机用的料缸

导热凝胶的成份还真不清楚.0.0
