CYJK-B Series of Toque Adaptive Control Device for Pumping Unit -018CJS-B series of toque adaptive control device for pumping unit (hereinafter referred to as the device) is applicable for energy saving and stepless regulation of pumping units without load, with light load or variable load, with advanced torque vector control and frequency conversion technology, adhering to the torque control theory of motors. The device detects load at real time via built-in special energy-saving optimized control software combining with single-chip microprocessor. And it can adjust the voltage and current input to motors according to load variations, ensuring accurate match between output power of motor and load demand and controlling automatically output torque of motor so as to save energy, without changing motor rotate speed and reducing pumping quantity. The product has the frequency conversion function, which can regulate the jig frequency of pumping unit without step limitation and reduce largely start current of motor, reducing the damages of motor isolation due to impulse current and operating temperature, maintenance quantity of motor, as well as extending service life.Technical parameters:1. working voltage: three-phase 380V±10％, 50Hz2.
