蠕動(dòng)泵；軟管泵與螺桿泵的優(yōu)缺點(diǎn)分析，我知道蠕動(dòng)泵的優(yōu)點(diǎn)，還有其它達(dá)人可以補(bǔ)充的嗎？美國Thermo蠕動(dòng)泵
- Design 設(shè)計(jì)上Cavity pumps rubber stator entraps abrasive particles - steel rotor works against this and wears very quickly 介質(zhì)的顆粒易附著在定子的表面造成轉(zhuǎn)子的極高磨耗Peristaltic pumps have no metal in the fluid media to wear away. 蠕動(dòng)泵無金屬部件與介質(zhì)接觸Cavity pumps cannot run dry whereas peristaltic pumps can 螺桿泵不允許干轉(zhuǎn)，蠕動(dòng)泵可以干轉(zhuǎn)Cavity pumps utilize seals - same issues as centrifugal 螺桿泵需要機(jī)械密封Peristaltic pumps have no seals and therefore don’t require flushing of fluids 蠕動(dòng)泵無機(jī)械密封，因此無需沖洗系統(tǒng)No dilution of pumped media 不會(huì)稀釋介質(zhì)No environmental disposal problem of waste flush fluids. 無介質(zhì)泄漏問題Cost - Initial cost of progressive cavity pumps is lower compared to hose pumps, but maintenance and replacement parts are expensive. 螺桿泵初購成本低，但維護(hù)成本高Peristaltic pumps are a superior environmental friendly alternative due to their unique design蠕動(dòng)泵由于獨(dú)特的設(shè)計(jì)，是對(duì)環(huán)境最為友善，不會(huì)對(duì)環(huán)境發(fā)生危害的泵型
