The servo magnetic gear pump beverage filling machine is mainly composed of a pump head, a magnetic driver, an electric motor, etc. The magnetic driver consists of an outer magnetic rotor, an inner magnetic rotor, and a non - magnetic isolation sleeve. When the electric motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and the isolation sleeve, driving the inner magnetic rotor connected to the impeller to rotate synchronously. This realizes contact - less synchronous power transmission, transforming the dynamic seal structure that is prone to leakage into a zero - leakage static seal structure.
The gear pump is the core component of the filling machine. It uses a pair of meshing gears, one of which is the driving gear driven by the servo motor, and the other is the passive gear driven by the driving gear. When the gears rotate, the liquid enters the pump chamber from the suction port. As the gears turn, the liquid is extruded between the teeth. After the liquid discharge process, it is discharged from the discharge port, thus achieving the extraction and quantitative filling of the liquid.
Generally, a servo motor is used as the driving device. It has the characteristics of a wide speed - regulation range and high control accuracy. It can accurately control the rotation speed of the gear pump, thereby achieving precise quantitative filling.
It is a key component of the filling machine, responsible for extracting and filling the liquid. The pump body is usually made of corrosion - resistant 316 or 316L stainless steel, and the gears are made of wear - resistant and corrosion - resistant materials such as high - strength engineering plastic PEEK.
It includes a feed tank, a feed pipeline, a regulating valve, a filter, etc. Its function is to introduce the beverage to be filled into the filling machine, adjust and control the flow rate and pressure of the liquid, and at the same time filter out possible impurities to ensure the filling quality.
It is composed of a filling head, a filling port, a positioning device, etc. The filling head accurately fills the beverage delivered by the magnetic gear pump into the bottle, and the positioning device ensures the accurate position of the bottle during the filling process, guaranteeing the filling accuracy.
It is usually composed of a PLC, a touch - screen, electrical components, sensors, etc. Operators can set parameters such as filling volume, filling speed, and intermittent time through the touch - screen. The PLC controls the operation of the servo motor according to the set parameters, as well as the start, stop, speed regulation, and other operations of the entire filling machine. It also monitors the filling process in real - time through sensors to ensure filling accuracy and stability.
The servo motor, combined with a high - precision magnetic gear pump, can achieve very precise quantitative filling. The filling accuracy can reach over three - thousandths, effectively ensuring that the filling volume of each bottle of beverage is consistent.
The rotational movement of the gear pump can quickly extract and fill the liquid. The flow rate can reach 120L per minute or even higher. It can be used for high - speed filling and tracking filling, greatly improving production efficiency.
Since the gear pump is a positive - displacement pump with a stable flow rate, there is basically no flow pulsation. This makes the filling process more stable, reducing phenomena such as foaming and splashing of the beverage during filling. It is suitable for filling various types of beverages.
It can be used for filling various types of beverages, such as carbonated beverages, fruit juice beverages, tea beverages, dairy beverages, mineral water, etc., as long as the viscosity and fluidity of the beverage meet the working requirements of the gear pump.
The magnetic gear pump has a relatively simple structure with few components. It uses magnetic drive and does not require a shaft seal, reducing leakage points and lowering the maintenance cost and repair difficulty. At the same time, the overall structural design of the filling machine is also convenient for cleaning and disinfection, meeting the hygienic requirements of the food and beverage industry.
It is widely used in the filling production of various beverages, such as large - scale production and filling of carbonated beverages, fruit juice beverages, tea beverages, dairy beverages, mineral water, etc.
It can be used for filling liquid medicines such as oral liquids and syrups. Its high - precision filling performance can meet the strict requirements of the pharmaceutical production for dosage accuracy.
It is suitable for filling liquid cosmetics such as toners, lotions, and makeup removers, ensuring the consistency and quality stability of product packaging.
