"2本帖最后由 juniger 于 13:57 编辑 2.3 7.3 h，介质是水，有哪些恒流量控制方法？！ 1、离心泵+流量计"PLC？ 2、往复泵？ 3、罗茨泵？哪种方法比较好啊，兄弟们？流量控制要求不高，2左右就可以。"

"流量控制要求不高，7左右就可以。"

"离心泵加一个流量计加个高低报警计量泵，咨询一下是否可靠"

"离心泵"流量计"PLC这个再加流量高低报警，是最稳定安全的"

"离心泵"流量计"PLC这个再加流量高低报警，是最稳定安全的同意5楼兄弟的意见，早在 80年代个气动仪表时代，上述组合将流量控制在8%的精度都没有问题何况现在？"

"计量泵都是小型的哎我这这精度要求很低。"

"波动哎，入口是个大水池，液位会波动。"

"我这精度真没啥要求。如果是PLC"流量计"调节阀这种组合，主要是还要编程。我就是想搞个泵（往复式）到时候调在那里就好了。"

"离心泵"流量计"变频器"

"容积式泵都可以啊。齿轮就好了"

"齿轮泵是个好选项。齿轮泵基本上都是恒流量的吧？"

Reply #122020-01-03

"是的。按你参数选型就好了。"

"您好！齿轮不是好的选项。齿轮是需要介质润滑的，水没有润滑性，所以不推荐使用。可以选用螺旋转子泵。完全满足您的要求。"
