SYSTEM FOR PUMPING A FLUID AND METHOD FOR ITS OPERATION |
摘要 |
A method of operating a system (16) for pumping a fluid, which system comprises: a pump (17) for pumping the fluid; and a variable speed motor (20) for driving the pump (17). The method comprises the steps of: identifying a first system parameter (PI); identifying a second system parameter (P2) which is a function of the torque of the pump; setting a target value (Pl0) for a first system parameter; monitoring the first system parameter (PI); establishing a target value (P2o) for the second system parameter based on the difference between the target value and the measured value of the first system parameter; monitoring the second system parameter; and regulating the rotational speed of the pump such that the difference between the monitored value and the target value of the second system parameter is minimised. A system for implementing the method is also disclosed. |
