蠕動泵；軟管泵與螺桿泵的優(yōu)缺點分析，我知道蠕動泵的優(yōu)點，還有其它達人可以補充的嗎？美國Thermo蠕動泵
- Design 設計上Cavity pumps rubber stator entraps abrasive particles - steel rotor works against this and wears very quickly 介質的顆粒易附著在定子的表面造成轉子的極高磨耗Peristaltic pumps have no metal in the fluid media to wear away. 蠕動泵無金屬部件與介質接觸Cavity pumps cannot run dry whereas peristaltic pumps can 螺桿泵不允許干轉，蠕動泵可以干轉Cavity pumps utilize seals - same issues as centrifugal 螺桿泵需要機械密封Peristaltic pumps have no seals and therefore don’t require flushing of fluids 蠕動泵無機械密封，因此無需沖洗系統(tǒng)No dilution of pumped media 不會稀釋介質No environmental disposal problem of waste flush fluids. 無介質泄漏問題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，但維護成本高Peristaltic pumps are a superior environmental friendly alternative due to their unique design蠕動泵由于獨特的設計，是對環(huán)境最為友善，不會對環(huán)境發(fā)生危害的泵型
