Safety precautions for the operation of the impeller type aerator

Frequently check whether the supporting rod connecting screws, impeller locking bolts, and impeller wide plate bolts are loose. If the bolts are found to be loose, they should be tightened in time. 2. Safety precautions for the operation of the impeller type aerator 1. The impeller type aerator using 380v three-phase AC must use a dedicated circuit for the power supply, and must be powered by an electrician in accordance with the power supply safety operation procedures.

The motor must be equipped with leakage, single-phase, low-voltage protection devices to ensure the normal operation of the circuit. The power cord should use three-phase four-wire concentric rubber cable, the recommended wire diameter is 4x2.5 mm, the wiring is firm, and the grounding is stable.

The input power supply voltage is 380v, and the voltage fluctuation does not exceed 5% of the rated voltage taxi, so as to prepare for long-term use of low voltage and damaged motors. Before using the impeller aerator, please charge the 10*~30* Wholesale Prawn Pond Aerator Manufacturers oil in the speed box (the fuel grade is carried out according to the product manual), and let the inspector charge it so that it can work without the sad person’s oil.

To avoid damage to parts and motors. It is strictly forbidden to fix the impeller type aerator with metal wires such as iron wire. When maintaining, maintaining, handling or disassembling the impeller aerator, the power must be cut off to ensure personal safety.

When turning on the power of the impeller aerator, no one can go to the fishing ground to prevent electric shock and machine accidents.

The rate of dissolved oxygen consumption in the pond

The upper dissolved oxygen will not be replenished after it is reduced, and the lower dissolved oxygen will be quickly consumed. Because at high temperatures, the photosynthesis of phytoplankton is particularly strong and will produce a large amount of oxygen, causing the dissolved oxygen on the surface of the water body to reach saturation, while the dissolved oxygen at the bottom of the water body is relatively low. The rate of dissolved oxygen consumption in the pond.

When the frequency conversion aerator is turned on, it can cause the fish pond water body to circulate vertically, so that the dissolved oxygen of the entire fish pond water body reaches a saturated state, thereby improving the water quality. If you want to know more exciting content, please pay attention to us! When the ambient temperature is too high, what problems should be paid attention to when using the frequency conversion aerator?

When the pond water temperature is high, a large amount of feeding will cause the water quality to be too fertile, to have a lot of organic matter in the water, to have a large oxygen difference between the upper and lower layers, and to owe a large “oxygen debt” in the lower layer.It is generally not suitable to turn on the frequency conversion aerator in the evening. Because the time cooperation is about to stop, the dissolved oxygen will be evenly distributed after the frequency conversion aerator is turned on.

The variable frequency aerator will be turned on until 7-8 in the morning, and the fish will not stop after they are not floating. When the 'oxygen debt' is large, use more frequency aerators. The China Prawn Pond Aerator Manufacturers company's main business: inverter aerator production, inverter aerator sales, inverter aerator manufacturers, inverter aerator wholesale, etc.

The frequency conversion aerator has the effect of lifting water up. At noon on sunny days in summer and autumn, especially for fish ponds with fertile water, turn on the frequency conversion aerator for 2-3 hours. In the summer, when the temperature rises, the pond will lack oxygen due to excessive fish mouths or other organisms consuming oxygen, causing the fish to float
