Material Characteristics
Viscosity: The rotor pump filling machine is suitable for high-viscosity materials, but different models of equipment have differences in viscosity adaptability. If the viscosity of the gypsum material is very high, a model specifically designed for high viscosity should be selected, such as equipment with a high-torque drive system and an appropriate rotor structure, to ensure that the material can be smoothly transported and filled.
Particle Size: If the gypsum material contains particles, a filling machine with a large gap between the rotor and the pump body and made of wear-resistant materials should be selected to prevent the particles from wearing the equipment components, which may affect the filling accuracy and the service life of the equipment. For example, rotors and stators made of cemented carbide or ceramic materials can better handle materials containing particles.
Filling Accuracy Requirements
Metering Method: Select an appropriate metering method according to the requirements for filling accuracy. Common metering methods include volumetric metering and weighing metering. Volumetric metering determines the filling volume by controlling the number of rotations of the rotor, which is suitable for situations where high accuracy is required and the material density is stable; weighing metering controls the filling volume by weighing the weight of the container after filling, which has higher accuracy and can adapt to changes in material density, but the equipment cost is relatively high.
Accuracy Index: Specify the required filling accuracy, such as ±0.5% or ±1%. Generally speaking, high-end rotor pump filling machines can achieve higher filling accuracy through advanced control systems and precise mechanical components. For example, using a servo motor to drive the rotor, combined with high-precision sensors and an intelligent control system, can accurately control the rotation speed and rotation angle of the rotor, thereby improving the filling accuracy.
Production Capacity
Filling Speed: Select a filling machine with an appropriate filling speed according to the production scale and output requirements. The filling speed is usually measured by the number of bottles filled per hour or the number of liters filled per hour. For large-scale production, equipment with a fast filling speed should be selected, such as filling machines with multiple filling heads or a high-speed rotor drive system, to improve production efficiency.
Production Cycle: Consider the overall production cycle of the production line to ensure that the working speed of the filling machine matches the previous and subsequent processes to avoid production bottlenecks. For example, if the supply speed of the gypsum material in the previous process is limited, equipment with too fast a filling speed cannot be selected, otherwise it will lead to insufficient material supply and affect the continuity of production.
Equipment Performance and Quality
Material: The parts of the filling machine that come into contact with the gypsum material should be made of corrosion-resistant and wear-resistant materials, such as 316L stainless steel or food-grade plastic, etc., to ensure the service life of the equipment and the quality and safety of the material. For occasions with high hygiene requirements, materials that meet the relevant hygiene standards should also be selected.
Sealing Performance: Good sealing performance is the key to preventing gypsum leakage, ensuring filling accuracy, and maintaining a clean working environment. Select a filling machine with a reliable sealing structure, such as using mechanical seals or lip seals, etc., to ensure that there will be no leakage during long-term operation.
Brand and Reputation: Select filling machine manufacturers with well-known brands and good reputations. Their products are usually more guaranteed in terms of quality, performance, and after-sales service. You can learn about the evaluations and usage experiences of relevant brands by consulting product materials, consulting other users, or on industry forums.
Degree of Automation
Operation Mode: Select an appropriate operation mode according to the enterprise's personnel configuration and production management needs. Manual filling machines are suitable for small-batch and multi-variety production, with simple operation but high labor intensity; semi-automatic filling machines achieve automation in some links, such as material transportation and filling, which can improve production efficiency; fully automatic filling machines can achieve full-process automation from material transportation, filling, capping to labeling, greatly improving production efficiency and product quality stability, but the equipment cost is relatively high.
Control System: An advanced control system can achieve precise control and monitoring of the filling machine, and has functions such as fault diagnosis, automatic alarm, and data recording. For example, a filling machine with a PLC control system can perform parameter setting and operation through a touch screen, which is convenient and fast, and can monitor the running status of the equipment in real time, and discover and solve problems in a timely manner.
After-sales Service
Technical Support: The manufacturer should have a professional technical team that can provide users with timely and effective technical support, including services such as equipment installation and debugging, operation training, and fault repair. When the equipment malfunctions, it can respond quickly and dispatch technicians to the site to solve the problem, reducing the downtime.
Spare Parts Supply: Ensure that the manufacturer can stably supply the vulnerable parts and accessories of the equipment for a long time to ensure the normal maintenance and repair of the equipment. Some small manufacturers may have problems in spare parts supply, resulting in difficulties in equipment repair and affecting production.
