Liquid filling flow control problem
Thread Content
During liquid filling (methanol), in order to control the filling flow rate. There are two options: one is to use a control valve to regulate the amount of backflow and thereby control the filling rate; the other is to use an inverter to control the pump speed in order to regulate the filling rate. Which of the above two options is better, and why? Thank you all for your help.
Reply to 1# yuexuan: It is recommended to choose the former as it is easier to control
That is, I recommend the former! Facilitates control!
First, a control valve is used to regulate the amount of backflow and thereby control the filling rate, which results in lower investment costs; this method is commonly used these days. Second, an inverter is employed to control the pump speed in order to regulate the filling rate. To save power, more investment is needed; actually, an inverter doesn’t cost that much
