Submersible reflux pump(also called submersible axial flow pump) is a specially designed pump that is used for pumping fluids, particularly wastewater or sewage, from a lower elevation to a higher elevation. These pumps are designed to provide maximum efficiency and reliability, with the ability to pump large volumes of fluids over extended periods of time. One of the unique features of submersible reflux pumps is that they are entirely submerged in the fluid they are pumping. This design allows for minimal noise and vibration during operation, making them a popular choice for residential and commercial applications. In this article, we will explore the benefits and uses of submersible reflux pumps, as well as the different types available in the market.
The function of the submersible reflux pump is to set the submersible reflux pump in the pump room to increase the sludge to the front end of the biological reaction tank. Because the mud point of the secondary sedimentation tank is lower than the height of the reaction tank, the pump will be used. In addition, the remaining sludge pump can also be set in the submersible refluex pump room, and the remaining sludge can also be mentioned in the sludge treatment system. The role of submersible reflux pump is mainly reflected in the following aspects:
1. Adjust the concentration of the mud concentration of the biological reaction pool. Site difference between sludge can sometimes lead to a reduction in the concentration of mixed liquid in the biological reaction tank. In order to maintain the concentration of the sludge, a large sludge return ratio is adopted.
2. The return sludge can be regenerated. In the later stages of breathing, the activity can be fully recovered and even enhanced. After the sludge enters the reaction pool and the sewage contacts, it can give full play to its adsorption, concrete, precipitation and degradation performance, accelerate the reaction process of active sludge, and improve the reaction effect.
Features
Special design is made to the operating mode of short lift and large discharge.
The main equipment employs the stainless structure of the punched components, resulting in very good hydraulic performance and high efficiency.
The integrated installation design can realize the quick underwater installation.
The dual mechanical sealing arrangement and the multiple motor protection will improve operating reliability.
