• The high-speed aerator is good for aquaculture

1. High oxygen content per unit of water
It can greatly increase the breeding density of the breeding pond, greatly improve the utilization rate of the fish pond, and increase the yield per mu.
2. High oxygen content per unit of water
As the breeding density increases, the breeding area decreases, which effectively reduces labor costs and can be easily carried out.
maintain.
3. Multi-layer farming
According to the living space of the fish, different types of fish are cultured in different water depths to increase the breeding species and increase the yield per mu.
Don't worry about the lack of oxygen in the fish.
4. Stable water quality
Due to the increase of dissolved oxygen in the water, the pond material circulates quickly, creating a good condition for the reproduction of plankton.
parts to keep the water quality stable.
5. Improve the utilization rate of the bait
Due to the improvement of dissolved oxygen in the pond water, the speed of material circulation is accelerated, and the metabolism of fish and shrimp is promoted.
It is beneficial to the growth of fish and shrimp and improves the utilization rate of bait.
6. It is beneficial to prevent and cure fish and shrimp diseases

2. High-efficiency ternary flow impeller
The ternary flow energy-saving impeller adopts a full three-dimensional simulation design, optimizes the air duct structure, and greatly improves the efficiency of the impeller. Advanced five-axis machining equipment processing, aviation aluminum-magnesium alloy material, the tensile strength reaches 570MPa, the impeller is light in weight, and the high-speed operation is more stable.

3. High-efficiency high-speed inverter
The high-efficiency high-speed inverter has a speed regulation range of 0-1000hz, a wider speed regulation range, and has excellent overcurrent and overvoltage suppression, ensuring that no overcurrent, overvoltage, and other faults occur under various working conditions. Excellent vibration suppression control algorithm is adopted to ensure stable operation of various inertias on site. With the unique high-robustness design scheme, when the power grid is shaken or the power is suddenly cut off, the drive can ensure non-stop and reliable and stable operation through this function. High-efficiency and energy-saving: Adopt a high-efficiency energy-saving control algorithm to ensure that the motor always works in the high-efficiency range.

4. Integrated direct drive
The impeller and the motor are coaxially integrated, and there is no need for intermediate transitions (such as pulleys, couplings, and other connecting components), the transmission loss is reduced to zero, and the transmission efficiency is 100%.

5. Microcomputer control system
The touch screen has built-in PLC and IoT modules, which can provide a variety of operating modes, and the mobile APP can be used to monitor the operation of the equipment anytime, anywhere.
