There are many types of essential oils with significant differences in viscosity, ranging from light and thin lemon essential oils to viscous rose essential oils, which require high adaptability for filling and capping equipment. Common pain points encountered in the production of small and medium-sized enterprises: Traditional equipment adopts a fixed speed design, which is prone to problems such as large deviation in filling volume, blockage of pipelines by viscous materials, splashing and leakage of light and thin materials when adapting to materials of different viscosities; Manually adjusting the speed has low efficiency and inaccurate parameter matching, resulting in a decrease in product qualification rate; Frequent speed regulation can also damage equipment motors, increase maintenance costs, and seriously restrict the production efficiency of multiple product categories.

The application of variable frequency speed regulation technology has become the core solution to solve the problem of adapting multi viscosity materials. This technology uses a vector frequency conversion control module to accurately adjust the speed of the filling pump and the capping motor, achieving dynamic control of "viscosity adaptation - precise speed matching". For high viscosity essential oils, the filling pump speed can be reduced to slow down the feeding speed and avoid incomplete filling caused by slow material flow; For low viscosity essential oils, moderately increase the rotational speed to ensure filling efficiency, and at the same time, cooperate with anti drip filling nozzle design to prevent splashing and liquid leakage.

In terms of technological innovation, the equipment adopts a frequency conversion and servo collaborative control architecture, which improves the speed adjustment accuracy to ± 1r/min, ensuring that the filling amount error of different viscosity materials is ≤ ± 0.1ml. At the same time, the system is equipped with multiple viscosity adaptation parameter libraries, covering the speed parameters of common essential oil categories. Operators only need to call them with one click, without repeated debugging, greatly reducing category switching time and improving production capacity. In addition, frequency conversion speed regulation technology can reduce the starting surge current of the motor, reduce equipment wear, extend the service life of the motor, and reduce maintenance costs.

It is worth noting that this technology also has the advantage of energy consumption optimization. Dynamically adjust the rotational speed based on material viscosity to avoid energy waste caused by traditional equipment operating at full load, saving 15% -20% energy compared to fixed speed equipment. Paired with an intelligent monitoring module, it provides real-time feedback on the material flow status and speed matching, forming a closed-loop control system of "monitoring regulation optimization" to further enhance production stability.
