The differential speed control of the horizontal screw centrifuge is achieved through a series of complex mechanical and electronic systems. The main purpose is to ensure that the relative speed (i.e. differential speed) between the drum and the screw can be stably maintained within the set value range to optimize the separation effect of the material. The following are the specific implementation methods of differential speed control: It is the perfect fusion of advanced mechanics and precision electronics. This allows for optimal separation outcomes every time, thanks to the precise maintenance of the set value range between the drum and screw, known as the differential speed.
Differential control principle
The differential control principle of the horizontal screw centrifuge is based on the use of a differential. The differential connects the drum and the screw, and controls the relative speed between the drum and the screw by adjusting the speed ratio of the input and output shafts. When the drum rotates at a certain speed, the differential transmits torque to the screw through its internal mechanism, causing the screw to rotate at a slightly slower or faster speed, thereby achieving differential speed. Delve into the mechanics of our horizontal screw centrifuge. With a built-in differential, the drum and the screw are connected and the relative speed between the two can be controlled by tweaking the input and output shafts’ speed ratio. You can achieve the perfect level of differential speed to achieve the results you need.
Control method
Mechanical differential control:
In early or some simple horizontal screw centrifuges, the differential may be adjusted mechanically, such as adjusting the gear ratio inside the differential or using friction plates to control the speed difference. However, this method has low accuracy and limited adjustment range. This is a popular and effective way to adjust differential speeds. With mechanical adjustments, such as gear ratio adjustments or friction plates, you can benefit from higher precision and a wider range of adjustment.
Electronic differential control:
Modern decanter centrifuges generally use electronic differential control, which accurately controls the speed of the main motor and the auxiliary motor through electronic devices such as frequency converters, thereby achieving precise adjustment of the differential speed. Electronic differential control has the following advantages: The electronic differential control in modern decanter centrifuges boasts several advantages. With precise adjustments to the speed of the main motor and auxiliary motor through electronic devices such as frequency converters, operators can achieve accurate control and maximize efficiency. This innovative technology also eliminates the need for manual adjustments, reducing the potential for errors and increasing overall productivity.

Specific implementation steps
Taking electronic differential control as an example, the implementation steps of differential control are as follows:
Set the differential value:
Set the target differential value in the control system according to the material characteristics and processing requirements. Efficiently manage your production processes with the specific target differential value for your material and processing needs.
Monitor the actual differential:
Monitor the actual differential value in real time through sensors installed on the drum and screw. Keep track of your machine’s performance accurately and efficiently with our real-time differential sensors.
Compare and adjust:
Compare the actual differential value with the target differential value. If there is a difference, adjust the speed of the main motor and the auxiliary motor through the control system to make the actual differential value close to the target value.
Feedback and optimization:
The control system continuously optimizes and adjusts the strategy according to the feedback signal to ensure the stability and accuracy of the differential. With a continuous optimization process and precise feedback signals, the control system ensures stable and accurate performance through strategic adjustments.
Key parameters
During the differential control process, the following parameters have an important influence on the control effect:
Drum speed:
The drum speed directly determines the centrifugal force on the material inside the centrifuge, and is the basis of differential control. With its precise and powerful drum speed, this centrifuge puts you in full control of the centrifugal force exerted on your materials. This differential control allows for unparalleled accuracy and efficiency in your experiments.
Screw speed:
The difference between the screw speed and the drum speed is the differential speed, and its size has a direct impact on the separation effect of the material. Differential speed ratio: The differential speed ratio refers to the ratio of the drum speed to the continuous rotation speed, and is also an important parameter in differential speed control. Maximize the separation effect of the material by controlling the differential speed ratio – the ratio of the drum speed to the continuous rotation speed. The differential speed ratio is a crucial parameter that influences the efficiency of material separation.
Summary
The differential speed control of the horizontal screw centrifuge is achieved mechanically or electronically, among which electronic differential speed control is widely used due to its high precision, wide adjustment range and high degree of automation. In the differential speed control process, it is necessary to accurately set the target differential speed value, and ensure the stability and accuracy of the actual differential speed value through real-time monitoring and adjustment.
At the same time, key parameters such as drum speed, screw speed and differential speed ratio have an important influence on the control effect. It’s a precise, automated, and versatile tool for controlling differential speeds. In addition to real-time monitoring and adjustment, it’s important to set the target differential speed value accurately, while also considering the impact of parameters like drum speed, screw speed, and differential speed ratio on control effectiveness.
