Introduction

QDT type Submersible flow propeller is extensively used for the oxidizing flow propelling and agitation in various types of biochemical tanks during the water treatment process, also can be used for river frost protection and, landscape water circulation etc.. The low-speed flow propeller consists of submersible motor, speed-reducing device, blades, and installation system etc. The product is characterized by low power (1.5-9KW), low rotate speed (34~85rpm), large diameter of the blades (1100-3000mm),low- speed rotation, production of large-volume flow field and wide scope of service. The sweptback, banana-shaped blades have self- cleaning function, which is finishing cast with PU or glass fibre reinforced plastics and highlighted by light weight, high strength, and good anticorrosion etc. The excellent frictional property can ensure the a good damping effectiveness with the fluid in low speed movement status to produce gradual water flow.

Structure

Besides the flow propelling and producing water flow, this series of products also have mixing function as shown in the drawing:

Application

The submersible mixers are mainly used for mixing, agitating and making ring flows in the process of municipal and industrial sewage treatment and can also be used for equipment maintenance of the landscape water circulation; through agitation, they can achieve the function of creating water flow, improving water quality, increasing oxygen content in the water and effectively preventing the sedimentation of the suspended substances.

Performance Parameters

The performance parameters of the submersible mixer are shown in the following table with the rated voltage of 380v and the frequency of 50Hz:
