Beschreibung
Zusammenfassung:	The utility model relates to a polyester melt viscosity control system which mainly comprises an oscillation viscosity instrument, a signal input unit, a control unit, a signal output unit and an executor, wherein the actuator is arranged on a polyester pipeline, the oscillation viscosity instrument is connected with the signal input unit through signals, the signal output unit is connected with the actuator through signals, a pressure detector is arranged on the polyester pipeline, and the pressure detector and the viscosity instrument are connected with a viscosity correcting unit through signals. The polyester melt viscosity control system has simple structure, convenient use and excellent effect, effectively eliminates the influences of pressure fluctuation in the polyester pipeline to the measurement of the viscosity instrument, eliminates the influence of the pressure fluctuation to the viscosity when the pressure of melt is increased in the switching period of a melt filter, greatly improves the viscos
