AI Technical Summary
Traditional waterwheel aerators suffer from low transmission efficiency, complex structure, low reliability, and easy failure of oil seals. Furthermore, the mechanical oil seal housing has poor heat dissipation, leading to oil leakage and shortened motor life.
The base and aluminum alloy flange are formed by stretching process, with heat dissipation holes. Combined with an external rotor direct drive motor and a non-conductive slip ring structure, the reduction mechanism is eliminated, achieving direct drive and efficient heat dissipation.
It improves transmission efficiency, reduces energy consumption, extends oil seal life, simplifies the structure, enhances equipment reliability and heat dissipation performance, and reduces manufacturing costs.
