There are significant differences between the functions and uses of the sewage mixer and the speed increasing machine. The following is a detailed analysis of the difference between the two:

First, functional differences

1. Sewage mixer:

- Main functions: The sewage mixer is a equipment specially used in the field of sewage treatment, which mixes sewage by rotating the impeller, makes the suspended matter and sediment in the sewage evenly mixed, and accelerates the treatment of oxygen and microorganisms to the sewage, thereby improving the treatment efficiency.

- Application scenario: Widely used in various sewage treatment plants, such as domestic sewage treatment, livestock and poultry breeding sewage treatment, industrial wastewater treatment, etc.

2. Speed increasing machine:

- Main functions: The speeder (also known as the speeder or reducer) is a device used to change the speed of mechanical equipment. It converts the input speed to the required output speed through the gear, worm and other transmission mechanisms to adapt to the operation needs of different equipment.

- Application scenario: Widely used in machine tools, conveying equipment, lifting equipment and other mechanical equipment to control the running speed of the equipment.

Second, structural differences

1. Sewage mixer:

- Structure: mainly composed of submersible motor, sealing mechanism, runner, hand hoist, electrical control and other parts. The submersible motor drives the wheel to rotate, and the suspended matter and sediment in the sewage are evenly mixed by stirring.

- Features: compact structure, smooth operation, high mixing efficiency, and has good sealing, dustproof, waterproof, anti-corrosion performance.

2. Speed increasing machine:

- Structure: The speed increasing machine is mainly composed of gear, worm, bearing and other transmission mechanisms. Through the combination of gears with different tooth numbers or worm gear drive, the input speed can be converted to the output speed.

- Features: The structure is relatively complex, but it can achieve accurate speed adjustment and transfer large torque. The low-speed accelerating machine usually adopts the gear transmission structure, while the high-speed accelerating machine may adopt the chain transmission structure.

Third, the difference in working principle

1. Sewage mixer:

- Working principle: The submersible motor drives the blade of the mixer to rotate at a high speed and produce a strong mixing effect. Under the action of the mixer, impurities and particles in the sewage are fully stirred and mixed to form a uniform suspension, while increasing the dissolved oxygen content of the sewage, which is conducive to the subsequent biological treatment process.

2. Speed increasing machine:

- Working principle: Based on the transmission of gears and the principle of worm, through the combination of gears with different number of teeth or worm gear transmission, to achieve the conversion of input speed to output speed. Through precise gear matching and bearing support, the speeder achieves smooth rotation, reduces noise and vibration, and has high transmission efficiency.

Fourth, the difference between use and application conditions

1. Sewage mixer:

- Use: It is specially used in the field of sewage treatment to improve the treatment efficiency of sewage by stirring.

- Application conditions: Suitable for sewage treatment plants of various sizes and industrial wastewater treatment stations that need to stir sewage.

2. Speed increasing machine:

- Use: Used to change the speed of mechanical equipment to adapt to different operating requirements.

- Application conditions: Select the appropriate growth model number and parameters according to the operating requirements of the specific equipment. For example, the low-speed speed machine is suitable for equipment with low speed and large torque (such as mixers, excavators, etc.), while the high-speed speed machine is suitable for equipment with high speed and small torque (such as fans, centrifugal pumps, etc.).

In summary, there are obvious differences between the sewage mixer and the speed increasing machine in terms of function, structure, working principle, use and application conditions. Sewage mixer focuses on the stirring function in the field of sewage treatment, and the speed increasing machine is a speed regulating device widely used in various mechanical equipment.
