When the unit is started up for the first time, is current used to control the flow rate of the pump?
Thread Content
Our device is new, and we are currently preparing the necessary documents for starting work. It is said that in the initial stage, the motor will be used to control the flow rate of the pumps based on the electric current level. Is that the case? If so, please provide detailed explanations, senior. Thank you!
During the first start-up, since there is no fluid in the pipeline on the downstream side, the flow control valve cannot function. If the pump’s outlet valve is opened fully at this time, it is very likely to cause the motor to experience overcurrent, leading to the pump tripping or being damaged. Therefore, it is necessary to use the pump’s outlet valve to regulate the flow, and the motor current is used to determine and control the flow rate.
