The servo rotor pump grease filling machine is mainly composed of a servo rotor pump, a servo motor, a quantitative control system, and related pipelines and valves. The servo motor drives the rotor of the rotor pump to rotate, forming multiple sealed working chambers inside the pump. When the rotor rotates, during the suction stage, the volume of the working chambers increases, creating a negative pressure, and the grease is sucked into the working chambers under the action of the pressure difference. Subsequently, in the discharge stage, the volume of the working chambers decreases, the grease is squeezed, the pressure rises, and it is pushed to the filling outlet. The quantitative control system realizes precise control of the filling volume by accurately controlling the rotational speed and rotation time of the servo motor, ensuring that the amount of grease in each packaging container meets the set standard.
High-Precision Filling
Combining servo technology with an accurate metering system enables extremely high filling precision. Generally, the error range can be controlled within ±0.5%, and some high-end models have even higher precision. This feature is crucial for products like grease that have strict requirements for dosage, as it can ensure the stability and consistency of product quality and avoid quality problems caused by inaccurate filling volumes.
High Adaptability
It can handle various greases with different viscosities and consistencies. Whether it is a high-viscosity, thick grease or a relatively low-viscosity one, it can perform filling smoothly. This enables it to function well when dealing with different formulations or brands of grease and can adapt to the shapes, sizes, and materials of multiple packaging containers, such as plastic buckets, metal cans, and hoses.
High Filling Efficiency
Depending on the specific models and configurations of the equipment, the filling speed varies, but overall it can meet the needs of large-scale production. The high filling speed can significantly improve production efficiency and shorten the production cycle. For grease production enterprises, it enables them to produce more products within a unit of time, thereby improving economic benefits.
Good Hygiene
The parts of the equipment that come into contact with the grease are usually made of food-grade stainless steel or materials that meet hygiene standards. Such materials are not only corrosion-resistant but also easy to clean and disinfect, effectively preventing the grease from being polluted and ensuring the hygiene and safety of the products. In some application scenarios with high hygiene requirements, such as the filling of grease for food machinery, this characteristic is particularly important.
Easy Operation
It is controlled by a PLC (Programmable Logic Controller) in combination with a human-machine interface (touch screen). Through the touch screen, parameters such as the filling volume and filling speed can be intuitively set and adjusted, making the operation simple and convenient. Meanwhile, the equipment has an aesthetically pleasing appearance design, meets the requirements of modern industrial equipment, and is stable and reliable during operation, reducing the difficulty of the operators' work.
Material Storage System
It is usually a hopper or storage tank made of stainless steel, with excellent sealing and heat preservation performance. Good sealing can prevent the oxidation of grease and the entry of impurities, and the heat preservation performance helps maintain the fluidity of the grease, especially in some environments with relatively low temperatures. Some material storage systems are also equipped with a stirring device. Through stirring, the components of the grease can be made more uniform, preventing precipitation and stratification and ensuring the consistent quality of the filled grease.
Filling System
The core parts include filling heads, metering devices, and valves. The number and form of the filling heads (such as single-head, double-head, or multi-head) can be flexibly adjusted according to actual production needs. The metering device can accurately control the amount of each filling, ensuring that the amount of grease in each packaging container is accurate. The valves are used to control the flow of grease and the start and stop of filling. Through precise valve control, accurate and efficient filling can be achieved.
Control System
It is mainly composed of a PLC, a touch screen, etc. Through the control system, comprehensive automated operation and precise control of the filling machine can be carried. For example, different filling parameters can be set, including the filling volume, filling speed, and the number of fillings. Meanwhile, it can also monitor the running state of the equipment, record production data, such as filling volume statistics and equipment running time. Once the equipment fails, the control system can promptly send out an alarm signal and provide an automatic diagnosis function to help maintenance personnel quickly locate and solve the problem.
Conveying System
It is composed of a conveyor belt, a transmission device, and a positioning device. The conveyor belt is responsible for conveying empty packaging containers to the filling position, the transmission device provides power for the conveyor belt, and the positioning device ensures that the containers accurately stay at the filling position, ensuring the smooth progress of the filling process. The efficient operation of the conveying system is one of the key factors for realizing continuous and stable filling.
Lubricating Oil Industry
In lubricating oil production and sales enterprises, it is used to divide large barrels of grease into small packages, such as the small canned grease commonly used for automobile maintenance and the small-package grease for lubricating industrial equipment. These sub-packaged small products are convenient for sales and use, meeting the needs of different users.
Industrial Equipment Manufacturing and Maintenance
It provides a quantitative grease filling service for the manufacturing process of various industrial equipment. For example, in machinery manufacturing enterprises, it is necessary to fill a precise amount of grease into the parts of the equipment to ensure that the equipment can obtain good lubrication during the initial operation. Meanwhile, during the equipment maintenance and repair process, this filling machine can also be used to divide the grease into suitable packages, facilitating the maintenance personnel to carry out equipment maintenance.
Automobile Manufacturing and Repair
In automobile manufacturing factories, it is used to fill grease into automobile parts (such as hub bearings, etc.). In automobile repair shops and after-sales service centers, this filling machine can divide the grease into packages that are convenient for use, such as the small-package grease for grease guns, facilitating the maintenance personnel to carry out automobile maintenance and repair.
Other Fields
It can also be applied to some special industries, such as the filling of grease for some equipment in the aerospace field and the filling of grease in some precision instrument manufacturing enterprises to ensure the precise operation of the instruments.
