The submersible pond aerator can operate normally within the specified range without cavitation, with a running noise of less than 70 decibels and smooth operation. The motor has sufficient rated power. It is sprayed with epoxy resin anti-corrosion paint, with a coating thickness greater than 300 μ m, and its surface is bright without sand holes, cracks, etc. The overcurrent components are sprayed with epoxy resin anti-corrosion paint.
The submersible pond aerator is equipped with water leakage protection alarm function in the oil chamber and motor chamber of 4kw or above. The impeller adopts an efficient and unobstructed design, which is a large channel impeller. The impeller is cast as a whole, and an internal anti loosening locking device is used between the impeller and the shaft. The impeller can be easily extracted from the bottom. The cable and wire sealing adopts a specially made vulcanized rubber sealing head, which can be easily replaced and effectively sealed. The cable adopts oil proof rubber sleeve cable, with a random cable length of 10m or configured according to user requirements. The mechanical seal structure is used for sealing, which is located in the oil chamber to ensure normal and reliable operation. The oil chamber has sufficient space to accommodate the expanding oil volume and can be easily replaced. The electric motor adopts a squirrel cage induction submersible motor with a protection level of IP68. The stator winding adopts F-class insulation, and the stator winding adopts H-class insulation. The maximum starting current is not more than 5 times the rated current, the efficiency is 85-95%, and the full load power factor is ≥ 0.8.
