QDT Low-speed Flow Propeller

Product Introduction of QDT low-speed flow propeller
Model QDT low-speed flow propeller is extensively used for the flow propelling in the oxidizing ditches in the technological process of the water treatment, agitation in various types of bio-chemical tanks and also used in the mixing and flow propelling for freezing prevention in the rivers, landscape water cycling and so on. The low-speed flow propeller consists of the submersible motor, speed-reducing device, vanes, installation system, etc. The product is characterized by low power (1.5~7.5KW), low rotational speed (36~135rpm), large diameter of the vanes (1000~2500mm), low-speed rotation, production of large-volume flow field and wide scope of service. The swept-back, banana-shaped vanes have the self-cleaning function, being shaped with the use of PU or aluminum alloy through precision casting and having such advantages as light weight, high strength, good resistance against corrosion and so on. Its excellent frictional property can ensure the production of the good damping effect with relation to liquid under the moving state of low rotational speed so as to create the gentle water flow. The series of products have also，the mixing function apart from the flow propelling and creation of water flow as shown in the drawing.
