Working Principle of the Rotor Pump: It mainly consists of a pair of synchronously rotating rotors (such as gear rotors, cam rotors, etc.). When the rotors rotate, multiple closed working chambers are formed inside the pump. During the suction stage, the volume of the working chamber increases, creating negative pressure, which sucks the hand - washing paste from the storage tank. During the discharge stage, the volume of the working chamber decreases, the pressure of the material increases due to extrusion, and the material is pushed to the filling outlet.
Principle of Servo Control: Operators input target parameters such as filling volume, speed, and pressure through the PLC or HMI. The servo control system generates control signals. The servo motor drives the rotor pump to start precisely controlling the flow rate and pressure of the hand - washing paste. Built - in sensors (such as pressure sensors and flow sensors) monitor the parameter changes in the filling process in real - time, and feed the data back to the servo control system. The system automatically adjusts the motor speed and output pressure according to the feedback signals to ensure the stability of the filling process. When the filling volume reaches the preset value, the system commands the rotor pump to stop running.
Drive System: Powered by a servo motor, it can accurately control the rotational speed and rotation angle of the rotor pump, thus achieving precise control of the filling volume of the hand - washing paste.
Rotor Pump Components: The core components, including the pump casing, rotors, etc. The rotors rotate inside the pump casing to achieve the suction and discharge of the hand - washing paste.
Filling Head: Connected to the outlet of the rotor pump, it accurately fills the hand - washing paste into the container. It is usually equipped with high - precision valves and flow control devices to control the start - stop and flow rate of filling.
Conveying Pipeline: Connects the storage tank, rotor pump, and filling head for transporting the hand - washing paste. The pipeline is usually made of stainless steel or non - toxic plastic that meets hygiene standards to ensure that the material is not contaminated.
Control System: Composed of PLC, touch - screen, etc., it is used to set and adjust filling parameters such as filling volume and filling speed. At the same time, it monitors the operating status of the equipment in real - time and has functions of fault diagnosis and alarm.
Material Storage Tank: Used to store the hand - washing paste to be filled, it usually comes with a stirring device to prevent the hand - washing paste from sedimentation, stratification, or adhesion, ensuring the uniformity of the material.
High - Precision Filling: The servo motor, combined with the precise flow control of the rotor pump, can control the filling error within a very small range, such as ±0.5%.
Wide Application Range: It can adapt to hand - washing pastes with different viscosities, and can stably fill high - viscosity hand - washing pastes containing particles or fibers.
Good Hygiene Performance: The components in contact with the material are made of materials that meet food and drug hygiene standards, such as stainless steel 304 or 316L, etc., and the structural design is convenient for cleaning and disinfection.
High Stability: The servo system has a strong dynamic response ability, which can maintain a stable flow rate and pressure during long - term filling operations, reducing equipment failures and filling quality problems.
Easy to Operate: Equipped with a human - machine interface touch - screen, the operation is simple and intuitive. Workers only need to set relevant parameters on the touch - screen, and the equipment can run automatically.
Daily Chemical Industry: Besides hand - washing paste, it can also be used for the filling of products such as facial cleansers, hand creams, and skin - care creams.
Pharmaceutical Industry: Suitable for the filling of drugs such as ointments and gels, meeting the high - precision and high - hygiene - standard requirements of drug production.
Food Industry: Can be used for the filling of sauces and paste - like foods such as jams and chocolate sauces, but it needs to meet the relevant hygiene standards of the food industry.
