前级真空
用于高压和超高压
深层、洁净的前级真空是极限真空和高真空或超高真空系统纯度的关键因素之一。
用于高真空系统的前级泵
细节决定成败
深度、洁净的前级真空是高真空或超高真空系统能够达到的极限真空和纯度的关键。
涡轮分子泵的前级泵必须与其最大允许前级真空相匹配。在气体流量较小的情况下,前级泵的极限真空对整个系统可达到的极限真空也起着决定性作用。
抽气速度既决定了抽气时间,也决定了泵系统在连续运行时可抽取的最大流量。如果前级泵无法处理气体量,涡轮分子泵的前级真空就会增加,从而导致泵过载并关闭。前级泵在低吸气压力下保持持续的最大抽气流量是非常有利的。
Institute of Radiation Physics at HZDR tests VACUU·PURE® 10
Michael Freitag works at the ELBE linear accelerator of the Institute of Radiation Physics at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR). As an operating engineer, he is responsible for the entire vacuum infrastructure and was delighted to be able to test the new 100% oil-free, abrasion-free VACUU·PURE® 10 screw pump from VACUUBRAND under…
