Application and selection of GH32/CH32 gear reduction motor in sewage treatment equipment

In sewage treatment equipment, GH32/CH32 gear reduction motors play an important role in providing stable and reliable power support for various treatment processes. The following will elaborate on its application in sewage treatment equipment and illustrate the key points of selection with examples. When selecting a new sewage treatment plant in Dongguan, Guangdong, the above factors were comprehensively considered. For the stirring device of the biochemical reaction tank, based on the volume and stirring requirements of the reaction tank, the required torque is calculated to be 50 N · m, the speed is 60 rpm, and the GH32/CH32 gear reduction motor with a reduction ratio of 20 is selected; For the sludge lift pump, considering the changes in liquid level and overload situation, a motor with 1.5 times overload capacity and a speed range of 50-150 rpm was selected, and a corresponding frequency converter was equipped. Through reasonable selection, the sewage treatment equipment of the plant operates stably with low consumption, achieving the expected treatment effect.

1、 Application scenarios

Mixing device

In the biochemical reaction tank of sewage treatment, it is necessary to thoroughly mix the sewage with microorganisms through stirring to improve the treatment effect. GH32/CH32
The gear reduction motor can provide suitable speed and torque for the mixer, ensuring even mixing. For example, in the biochemical reaction tank of a medium-sized sewage treatment plant, GH32/CH32 is installed
The stirring device driven by a gear reduction motor effectively promotes the decomposition of organic matter by microorganisms.

Sludge lift pump

To lift the settled sludge to the subsequent treatment stage, the motor needs to have a certain torque and speed regulation capability. GH32/CH32
Gear reduction motors can meet these requirements and ensure stable operation of sludge lifting. The sludge lifting system of a sewage treatment plant in a certain city has adopted this type of motor and successfully achieved efficient sludge transportation.

Filtering equipment

Such as belt filters, rotary filters, etc., require precise speed control and large torque output to ensure filtration efficiency and normal operation of the equipment. GH32/CH32
Gear reduction motors perform well in this regard, providing reliable power for filtration equipment.

Mud scraper

Used to remove sludge from the bottom of sedimentation tanks, its operation requires stable speed and high torque. At an industrial wastewater treatment plant, GH32/CH32
The scraper driven by a gear reduction motor effectively removes sludge from the sedimentation tank, ensuring the normal operation of the treatment process.
