1. Surface quality Aerating machine (vertical axis)‍

　　Its main structure: motor, impeller, floating block, 4 impeller cover, guide tube, balance plate, impeller shaft, lower connecting plate, upper connecting plate, connecting long bolts. The advantages of surface quality Aerating machine are simple structure, reliable work and easy maintenance. The disadvantage is that the aeration effect is mainly limited to the upper water surface, the bubble fragmentation is not obvious, the aeration efficiency is not high, and deep aeration cannot be carried out.

　　2. Diving quality Aerating machine (vertical axis)‍

　　Its main structure: submersible motor, pump casing, impeller, power take-off shaft, negative pressure cover, air intake pipe, water inlet guide funnel, machine base, water outlet, water inlet.

　　When working, the underwater submersible motor rotates to drive the centrifugal impeller, and the air is sucked from the outside through the air intake pipe and dissolved into the water. The rotation of the impeller makes the surrounding water flow into the surrounding waters through the water outlet, and the water in the surrounding waters flows to the surrounding of the impeller through the water inlet guide funnel and the water inlet, and in this process, the air is dissolved into the water.

　　The advantages of diving quality Aerating machine are simple structure, convenient maintenance, good bubble crushing effect and high aeration efficiency. The disadvantage of environmentally friendly little bees is that they can only be used for aeration in special sewage treatment tanks, and aeration cannot be placed in soft riverbeds, ponds, etc.

　　3. Turning disc quality Aerating machine (horizontal axis)‍

　　Its main structure: aeration plate, hollow shaft, geared motor, coupling, bearing seat. When working, the motor drives the hollow shaft and the aeration disc supported on the bearing seat to rotate. A part of the aeration disc is immersed in the water, and the water in the water area is thrown into the air by the aeration disc by rotating, so that the water and the air are mixed. The rotation of the aeration disk also drives the flow of nearby waters.
