Low Speed Propeller

Low speed propeller adopt deceleration device, including cycloidal reducer and gear reducer, according to the working conditions and user requirements to choose. It has low power (1 .5-7.5kW), low speed(36-115 r/min), large impeller diameter (1100-2500mm), and a wide service range. With polyurethane, fiber, stainless steel material precision cast banana blade, in line with the needs of hydraulic design. Blade has smooth surface, smooth shape, light weight, high strength, corrosion resistance, excellent friction performance, can ensure a good friction effect with liquid in low speed motion state, so as to create a good water flow. In addition to the mixing function, this series of products also have the role of pushing flow and creating water flow.

Range of application
Submersible mixers are mainly used for mixing, slackening and circulation in municipal and industrial wastewater treatment processes, as well as for the cultivation of landscape water environments protect, through the impeller rotation movement to achieve the effect of creating water flow, improve water quality, increase oxygen content in water, effectively prevent the deposition of suspended matter.

Reference For Type Selection
The type selection of submersible mixer is a rather complicated job. The correctness of the type selection will directly affect the normal usage of the equipment. The principle for the type selection is to enable mixer to give full play to its mixing function in the appropriate volume. This standard can generally be determined by the flow velocity. In line with the different technological requirement of the sewage treatment, the optimum flow velocity for the mixer type selection shall ensure the velocity range of 0.15~0.3m/s.

Before selection
①should determine the application place of submersible mixer, such as: sludge tank or biochemical tank;
②medium, such as: suspended matter content, temperature, PH value, etc;
③Pool size and installation method, and also considering energy saving factors, because it will affect the operation cost of the user in the future. Refer to the flow field diagram of the submersible mixer below.

Precautions For Selection
1、Application
2、Pool size
3、Media properties, viscosity, density, solid content, etc.
Warning:
The submersible mixer must completely submerse in the water;
The submersible mixer cannot operate in the inflammable, explosive, highly corrosive and high-temperature environment;
The minimum dive depth of the submersible mixer is 900mm.

The supporting power required by the mixer is determined according to the volume size, the density, viscosity and mixing depth of the mixing liquid, and one or more mixer should be used according to the specific situation. Please contact us, for the selection questions.
