AI Technical Summary
Existing impeller aerators have insufficient heat dissipation performance when operating under high load, which leads to motor overheating and affects equipment lifespan and operational reliability.
The support and fixing shells are made of aluminum alloy with high thermal conductivity. Combined with the cooling fan and the heat dissipation grooves of the protective shell, a forced convection heat dissipation channel is formed. The motor load is reduced by a two-stage variable speed gear set design. Automatic heat dissipation control is achieved by equipping a temperature detector and a PLC control module.
It achieves efficient heat dissipation, extends equipment lifespan, improves operational stability and efficiency, and reduces energy consumption.
