The rotor pump mainly consists of a pair of synchronously rotating rotors, such as gear rotors, cam rotors, etc. These rotors rotate within the pump body and convey liquid by periodically changing the volume of the pump cavity. When the rotors turn, the liquid is sucked into the pump cavity. As the rotors continue to rotate, the liquid is carried to the outlet and then extruded under pressure, thus achieving the transportation of the liquid.
Under the action of the rotor pump, the liquid is transported from the liquid storage tank to the filling head. The filling head is usually equipped with high - precision valves and flow control devices. When the container reaches the filling position, the valve of the filling head opens, and the liquid flows into the container under the pressure of the pump. By controlling the opening time of the valve or the rotational speed of the pump, the filling volume can be accurately controlled.
It includes components such as motors, reducers, and transmission chains. It is responsible for driving the movement of various components of the filling machine, providing power for the entire filling process.
It is responsible for the quantitative measurement of materials, such as metering containers, weighing sensors, etc., ensuring that maltose can be accurately filled according to the set amount.
It is composed of components such as filling heads and filling valves. It is responsible for filling maltose into containers. Some filling heads also have an anti - dripping function to avoid the dripping of liquid residues.
It usually adopts PLC and touch - screen operation. It is responsible for the operation control of the entire filling machine. Parameters such as filling volume, filling speed, and filling time can be preset, and the operating status of the equipment can be monitored. When a fault occurs, it can alarm in a timely manner and stop the machine.
It includes components such as conveyor belts and positioning devices. The conveyor belt transports empty containers to the filling position and, after filling, transports the filled containers to the next process. The positioning device ensures that the containers can be accurately aligned with the filling head during the filling process, improving the filling accuracy.
The flow rate of the rotor pump can be accurately controlled, enabling high - precision filling. The filling error can be controlled within a small range, meeting the precise requirements for the filling volume of maltose.
It can handle high - viscosity maltose and can also adapt to other liquid materials with different viscosities. In addition, it can accommodate various shapes and sizes of containers, such as glass bottles, plastic bottles, metal cans, etc.
Many components are made of food - grade or pharmaceutical - grade materials, such as stainless steel 304 or 316L, etc., which meet the hygiene requirements of food production. Moreover, its structural design is convenient for cleaning. The pump body and pipes can be disassembled for cleaning, and the filling head is also easy to clean.
The working process of the rotor pump is relatively stable. During long - term filling operations, it can maintain a stable flow rate and pressure, reducing equipment failures and filling quality problems, and improving production efficiency.
It generally has a user - friendly human - machine interface. Operators can master the operation method of the equipment through simple training. They can easily set various parameters on the touch - screen, such as filling volume, filling speed, etc., and view the real - time operating status of the equipment.
In addition to being used for the filling of maltose, it can also be used for the filling of fruit juices, beverages, dairy products, edible oils, seasonings, etc.
It is suitable for the filling of pharmaceutical products such as oral liquids, injections, and ointments, meeting the high - precision and high - hygiene - standard requirements of pharmaceutical products.
It can be used for the filling of daily chemical products such as shampoos, shower gels, and lotions, and can be flexibly filled according to different requirements of product packaging.
It can be used for the filling of chemical products such as lubricating oils, paints, coatings, and glues, and can adapt to chemical materials with different viscosities and properties.
