Abstract
PURPOSE: To control a valve which partially recyles a fluid on the discharge side to the suction side with a signal obtained by proportionally integrating temperature differences between those fluids on both the suction and discharge sides in case of a pump where characteristic similarities are established.
CONSTITUTION: A suction temperature thermometer 7 measures a fluid temperature T1 on the suction side and a discharge temperature thermometer 8 measures a fluid temperature T2 on the discharge side. An adding machine 9 calculates T2- T1=ΔT and inputs the resultant into an adding machine 11. The adding machine 11 inputs a differential temperature setting value ΔTs outputted from the adding machine 9 and calculates ΔT-ΔTs=Δ, and frausmits the output signal Δ to a controller 12.
