Wastewater Treatment Plant Submersible Mixer Propeller Electrical Motor

Features:

1. The two rows of independent mechanical sealing ensure the long-term and reliable operation of the submersible motor.

2. The international well-know high-quality bearings have longer service life, which is maintain free.

3. The unique sealing design for the cables removes the hidden danger of water leakage of the cables.

4. The shaft of the motor employs the stainless steel, and the rotors are inspected with the use of dynamic balancing, leading to smooth rotation.

5. The in-built leakage sensor and the device for the over temperature protection for the windings of the stator(No leakage

sensor for MA0.37/6 or MA0.55/4).

6. The mixer agitators have the stainless steel pressing impeller, which are of the sweptback shape through the optimized

design, resulted in high efficiency and self-cleaning function.

7. The vanes of the low-speed flow propeller are made of FRP, which are sweptback shape, have the self-cleaning function, the smooth and streamlined propeller surface distribut6es the propelling power equally.

Application:

The purpose of mixing, agitating and making ring flows in the process of municipal and industrial sewage treatment: active sludge tank, bioreactor tank, mixing tank, equalizing reservoir, sewage tank and ect.; The maintenance equipment for the landscape water environment, improving the quality of the water body; Creating water flow, effectively preventing the sedimentation of the suspended substances.

Type Description:

Structure & function:

The parts designed for the submersible mixer can allow the mixer to obtain optimum performance.

P.S. MA0.85/8 ,MA1.5/6,MA0.85/8 and MA1.5/6 mixer don’t have thermo-switches and leakage protectors.

Junction box:The junction box is entirely enclosed and separated from the environmental liquid and the stator bore.
Electrical motor: The Motor delivers rated output power; the rated voltage deviation is ±5%. If the motor is not overheated or running under loading conditions, a ±10% rated voltage deviation is allowable. But the motor shall run under the condition the inter-phase unstable extreme value is 2%.
Bearing: motor shaft is supported by double-row angular contact ball bearing and deep groove ball bearing.
Oil chamber: The oil is used for lubrication and cooling as well as separating penetrating fluid.
Install elevator system: The mixer can be programmed to lift up or drop down, and removed or installed without emptying the pond water.
Monitoring device: In the normal situation, the shaft temperature could not be over 80.
