working principle
The immersion of leaves under the water attenuation surface is achieved through the following actions Recharge and mix sewage sludge.
1. The liquid level is more broken: due to the impeller's water absorption and suction effect The sewage quickly circulates up and down Continuously breaking the liquid level Large areas of sewage with missing levels come into contact with the air Thus efficiently and rapidly absorbing oxygen.
2. Water jump: Under the strong propulsion of the impeller blades Water is sprayed out from the wheel rim in the form of a water curtain, forming a water jump and engulfing a large amount of air. The oxygen in the air quickly dissolves in the water.
3. Negative pressure zone oxygen absorption: When sewage quickly passes through the internal guide cone top of the impeller, a negative pressure zone is generated, and air is sucked in from the intake hole, further increasing the oxygen filling amount and reducing energy consumption.
a、 Due to the spray, suction, and rotation of the impeller, water circulates in a spiral shape up and down, thoroughly mixing sewage and sludge. Aerobic bacteria obtain a large amount of oxygen in a timely manner, accelerating the biochemical process of sewage Thus achieving the effect of rapid and efficient purification of sewage.

characteristic
The PE pump type impeller air blocking machine consists of an electric motor, coupling, gearbox, impeller lifting device, pump type impeller, and other parts.
1. Pump impeller: It has high power efficiency, large oxygen filling capacity, strong lifting ability, large water flow regulation, and simple structure Characteristics such as significant processing effect.
2. Gearbox: Horizontal adopts spiral gears, circular helical teeth, and two-stage transmission; Vertical adopts cylindrical helical gear three-stage transmission The gear is a hard surface High box density, with smooth transmission and low noise High mechanical efficiency Characteristics such as reliable operation. The designed service life exceeds 10 years.
3. Impeller lifting device: horizontally installed on the side of the reduction gearbox Can be within the rated range Adjust the immersion depth of the impeller freely Thus adjusting the oxygen filling amount. The vertical type is flat, and the lifting platform is adjusted by screws Adjust the immersion depth of the impeller.
