In sewage treatment equipment, GH32/CH32 gear reduction motors play an important role, providing stable and reliable power support for various treatment links. The following will elaborate on its application in sewage treatment equipment, and illustrate the key points of Selection with examples. A newly built sewage treatment plant in Dongguan, Guangdong took the above factors into consideration when constructing Selection. For the stirring device of the biochemical reaction tank, according to the volume of the reaction tank and the mixing requirements, the required torque is calculated to be 50 N·m and the rotation speed is 60 rpm, and a GH32/CH32 gear reduction motor with a reduction ratio of 20 is selected; for sludge For the lift pump, taking into account liquid level changes and overload conditions, a motor with 1.5 times overload capacity and a speed range of 50 - 150 rpm was selected, and equipped with a corresponding frequency converter. Through reasonable operation, the plant's sewage treatment equipment operates stably, consumes less, and achieves the expected treatment results.
1. Application scenarios
Stirring device
In the biochemical reaction tank of sewage treatment, it is necessary to fully mix the sewage and microorganisms through stirring to improve the treatment effect. GH32/CH32 The gear reduction motor can provide the appropriate speed and torque for the mixer to ensure uniform mixing. For example, in the biochemical reaction tank of a medium-sized sewage treatment plant, a GH32/CH32 The stirring device driven by a gear reduction motor effectively promotes the decomposition of organic matter by microorganisms.
Sludge lift pump
Lifting the settled sludge to subsequent processing requires a motor with a certain torque and speed regulation capabilities. GH32/CH32 Gear reduction motors can meet these requirements and ensure stable operation of sludge lifting. The sludge lifting system of a city's sewage treatment plant uses this kind of motor and successfully achieves efficient sludge transportation.
Filtration equipment
Such as belt filters, turntable filters, etc., require precise speed control and large torque output to ensure the filtration effect and the normal operation of the equipment. GH32/CH32 Gear-reduced motors excel in this regard, providing reliable power to filtration equipment.
Mud scraper
It is used to remove sludge at the bottom of the sedimentation tank, and its operation requires stable speed and large torque. In an industrial wastewater treatment station, GH32/CH32 The gear reduction motor-driven mud scraper effectively removes the sludge in the sedimentation tank and ensures the normal progress of the treatment process.
2. SelectionKey points
Load characteristics
According to the load characteristics of different equipment, such as the constant torque load of the mixing device, the variable load of the sludge lifting pump, etc., select the appropriate motor model and reduction ratio. For example, for the mixing device, since the load is relatively stable, you can choose a model with larger torque and relatively fixed deceleration; for the sludge lift pump, since the load will change with the liquid level, you need to choose a model with a certain overload capacity and speed range. .
working environment
Consider the harsh environments such as moisture and corrosive gases in sewage treatment plants, and choose motors with high protection levels and corrosion resistance. In a sewage treatment plant in a coastal area, due to the high salt content in the air, a sewage treatment plant with good anti-corrosion properties was selected. GH32/CH32 gear reduction motor ensures long-term stable operation of the motor.
Speed and torque requirements
According to the process requirements of the equipment, calculate the required rotation speed and torque. For example, in a belt filter, the motor speed and torque need to be accurately calculated based on the running speed and tension of the filter belt to select the appropriate reduction ratio and motor power.
Installation method
According to the structure and space constraints of the equipment, choose the appropriate installation method, such as horizontal, vertical, etc. In a sewage treatment station with limited space, in order to save space, we chose the vertically installed GH32/CH32 Gear reduction motor.
Energy saving requirements
On the premise of meeting process requirements, choose a motor with high efficiency and low energy consumption to reduce operating costs.
In summary, when applying GH32/CH32 gear reduction motors in sewage treatment equipment, it is necessary to fully consider the characteristics and needs of the application scenario, and ensure that the motor can operate efficiently and stably through scientific Selection, and provide a good foundation for the sewage treatment process. Provide a strong guarantee for the smooth progress of the project.
