Submersible Propeller

Introduction 

QDT type Low-speed submersible 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 submersible 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. Besides the flow propelling and producing water flow, this series of products also have mixing function as shown in the drawing. 

Working conditions 

'QDT' Low-speed Submersible propeller can run continuously in following conditions. 

1.Maximum allowable temperature of the medium for continuous operation is 40 °C [104 ° F].

2.The pH value of the medium is between 5-9.

3.The density of the medium does not exceed 1150 kg/m3.

4.During long-term diving operation, the maximum diving depth is 20 meters.
