流量閉環(huán)智能控制系統(tǒng)原理：高壓發(fā)泡機的流量傳感器測得的實際值與控制系統(tǒng)的設定值不斷進行比較，通過變頻器實現(xiàn)對電機轉速的控制，從而改變泵的流量輸出來達到調整任何流量的偏離。
Flow closed-loop control system,intelligent pressure foaming machine flow sensors the actual value of thecontrol system,and through xomparing continuously variable frequency xontrol or motor speed,thus changing the rlowrate of the pump to adjust any output flow deviation.
