Working principle of submersible blowers

Thread Content

A submersible blower is an underwater type of Roots blower that is widely used for aeration in water treatment, and it is also an improvement based on the Roots blower. Submersible blowers are currently most widely used in the river management industry, followed by the integrated water treatment industry. The submersible blower features a direct-drive mechanism, with a sealed, contactless rotor. The biaxially parallel three-blade impeller has a small amplitude, a long bearing life, and does not require a pulley to drive it. Submersible blowers evolved from rotary vane blowers, and their working principle is roughly the same as that of rotary vane blowers. Air intake and exhaust are both achieved through the rotation of the internal rotor. By the uniform rotation of two impellers on two parallel shafts in opposite directions, a certain amount of gas enclosed within the casing and the impellers is transported from the suction side to the discharge side. The conveying medium is air, free of water and oil. Submersible blowers are placed at the bottom of the water; they use the high pressure and airflow generated by their own diffusers, in combination with delivery pipes, to introduce air into the water. This helps to mix oxygen with the water, ensuring thorough stirring of the water body so that oxygen is evenly distributed throughout it. As a result, an aerobic environment is created for the numerous microorganisms present in the wastewater, allowing them to fully utilize their ability to break down pollutants and thus accelerating the process of wastewater treatment. Submersible blowers are important aeration devices in the water treatment industry. The submersible blowers produced by Shanghai Ruize Environmental Protection are widely used in this sector due to their stable operation, excellent aeration performance, simple installation and maintenance, and long service life The above article may not be reproduced or used without my permission.
