Working Principle
The glycerol filling machine with a servo rotor pump is composed of a servo motor and a cam rotor pump. The pump head is a metering pump with a positive displacement structure, and the displacement per revolution is a fixed value. By controlling the rotational speed through the servo motor, precise metering and filling of glycerol can be achieved.
Features
High-Precision Metering: The combination of the precise control of the servo motor and the stable delivery of the rotor pump enables high-precision glycerol filling. The filling error can be controlled within a very small range, meeting the precise requirements for the filling volume of different packaging specifications.
Wide Applicability: It can be applied to glycerol with different viscosities. Whether it is low-viscosity thin glycerol or high-viscosity thick glycerol, it can be filled stably and evenly. Meanwhile, it can also be used for filling other liquids with similar properties.
Flexible Adjustment of Filling Speed: The servo motor can adjust the rotational speed at any time according to production requirements, thereby realizing the flexible adjustment of the filling flow rate. It can not only meet the high-speed filling requirements during large-scale production to improve production efficiency but also achieve precise filling at a lower speed during small-batch production or the debugging stage.
Stable and Reliable Operation: The rotor pump has a simple structure, with low noise and small vibration during operation. Moreover, the servo motor has good control performance. The combination of the two makes the filling machine operate smoothly as a whole, reduces equipment failures and maintenance costs, and enables it to work stably for a long time.
Convenient Cleaning and Maintenance: The structural design of the equipment facilitates disassembly and cleaning. When replacing different types or batches of glycerol, it can be cleaned quickly and thoroughly to prevent cross-contamination and ensure product quality.
Main Components
Electrical Part: It includes power supply, key control, touch instrument, sensors, servo drivers, servo motors, etc., which are used to control the operating parameters of the filling machine, monitor the working status, and realize automated operations.
Oil Extraction System: It consists of an oil inlet pipeline, a cam rotor pump, an oil outlet pipeline, anti-drip and anti-leak nozzles, etc., and is responsible for the extraction, transportation, and filling of glycerol. Among them, the cam rotor pump is the core component, and its performance directly affects the filling effect.
Frame and Transmission Part: It provides support and installation foundation for other components of the filling machine, ensures the relative position accuracy among various components, and simultaneously transmits the power of the servo motor to the rotor pump through the transmission device to realize its normal operation.
Filling System: It includes filling heads, filling valves, etc. The design and precision of the filling heads have an important impact on the accuracy and stability of filling, and the filling valves control the outflow and stop of glycerol to ensure the smooth progress of the filling process.
Examples of Technical Parameters
The technical parameters of the glycerol filling machines with servo rotor pumps produced by different manufacturers may vary. Here are some common parameter ranges:
Filling Capacity: Generally between 100 milliliters and 5 liters, and it can be adjusted according to different packaging containers and customer requirements.
Filling Accuracy: The error is usually between ±0.5% and ±2%. High-precision filling machines can reach ±0.1%.
Filling Speed: About 10 to 100 bottles (or barrels) can be filled per minute. The specific speed depends on factors such as the filling capacity and the viscosity of glycerol.
Power Supply Requirements: Generally, it is alternating current of 220V/50Hz or 380V/50Hz, and the power is between 1 and 5 kilowatts.
Air Source Pressure: If the filling machine is equipped with pneumatic components, an air source pressure of 0.4 to 0.6MPa is usually required.
