Aiming at the technical defects of traditional deep well pump motors, including high noise, fluctuating energy consumption, delayed variable frequency response and strong start-stop impact, Jinyu Pump has completed independent R&D and upgrading of permanent magnet variable frequency motors and realized full independent control of motor systems. This technical upgrade optimizes the motor stator winding process and rotor dynamic balance structure, and is equipped with a newly self-developed variable frequency control chip. It can automatically adjust the speed according to water pressure and flow demand to accurately match working loads, solving the problems of high energy consumption and poor adaptability caused by constant-speed operation of traditional pumps. Meanwhile, noise reduction structure optimization, shock absorption gasket upgrade and precise adjustment of internal gaps greatly reduce operating noise and vibration. The upgraded variable frequency motors of Jinyu Pump feature faster response, more accurate speed regulation and quieter operation, supporting 24-hour uninterrupted variable frequency operation, effectively reducing start-stop loss and extending motor service life, achieving an integrated technical breakthrough of energy saving, low noise and high stability.
