High efficiency and low noise! Kaiquan KQLE intelligent variable frequency pump leads the new era of intelligent pump industry
Preface
As the core equipment for fluid transportation, the performance of the pump directly affects the efficiency and reliability of the entire system. With the continuous improvement of building energy conservation and intelligence, the requirements for pumps are also getting higher and higher.
Therefore, traditional single-stage pumps have ushered in many challenges in digitalization, intelligence, energy saving and noise reduction:
Low degree of digitization: The hybrid control mode leads to complex systems and cumbersome wiring, which is not conducive to standardized production and function expansion.
Low degree of generalization: There are large differences in systems from different manufacturers, lack of unified standards, and difficult maintenance and replacement.
Low degree of intelligence: Limited perception ability, only basic control can be achieved, and it cannot adapt to complex working conditions.
Low operating efficiency and high noise: Traditional control methods lead to low efficiency and high noise of pumps under low load conditions.
As one of the leaders in the field of domestic water pumps, Kaiquan has launched the KQLE smart variable frequency pump with its deep accumulation and innovative spirit in the field of pumps. This product integrates motors, water pumps and digital variable frequency controllers, bringing users an unprecedented use experience.
