Q：計(jì)量螺桿泵自動(dòng)控制變頻電機(jī)+變頻器與通過(guò)自動(dòng)沖程控制器來(lái)實(shí)現(xiàn)的自動(dòng)控制區(qū)別在哪？ </p> <p> <br /> </p> <p> A：”2種方式**終結(jié)果都是調(diào)節(jié)螺桿泵的流量，區(qū)別就是，變頻電機(jī)+變頻器是通過(guò)改變電機(jī)頻率(轉(zhuǎn)速)，實(shí)現(xiàn)調(diào)節(jié)流量的效果；自動(dòng)沖程變速器是通過(guò)改變螺桿泵的行程(電機(jī)轉(zhuǎn)速不變)，實(shí)現(xiàn)現(xiàn)調(diào)節(jié)流量的效果?！?</p>
