When choosing a rotor - pump filling machine suitable for you, various factors need to be considered comprehensively. Here are some suggestions:
In terms of production requirements:
Filling volume: Clearly define the range of the liquid volume for each filling operation to ensure that the filling volume of the selected filling machine can meet the requirements. For example, for small - scale cosmetic production, a filling machine with a smaller filling volume may be chosen; while for filling large - scale chemical liquids, a device with a large filling volume is required.
Filling speed: Select according to the production efficiency requirements. For large - scale production, a machine with high - speed filling is needed to improve production efficiency; if the production scale is small or the requirement for filling speed is not high, a filling machine with a moderate speed can be selected. For instance, during the peak season in the food and beverage industry, there is a higher demand for the speed of the filling machine, and a high - speed rotor - pump filling machine should be chosen.
Filling accuracy: For some products with high requirements for filling accuracy, such as pharmaceuticals and cosmetics, a filling machine with high filling accuracy is required. Generally speaking, the filling error of a high - quality rotor - pump filling machine can be controlled within a small range. Check the specific accuracy parameters of the equipment to determine whether it meets the requirements.
In terms of liquid properties:
Liquid viscosity: Different liquids have very different viscosities, and rotor - pump filling machines have different adaptabilities to liquids with different viscosities. For high - viscosity liquids such as sauces and pastes, a rotor pump capable of handling high - viscosity materials is required. The gap between the rotor and the pump casing of this type of pump is small, which can provide a relatively large pumping pressure; while for low - viscosity liquids such as clear water and alcohol, the requirements for the pump are relatively low.
Corrosiveness: If the liquid is corrosive, the material of the filling machine must have good corrosion resistance. For example, for corrosive liquids such as strong acids and alkalis, the parts of the pump body and pipelines that come into contact with the liquid should be made of corrosion - resistant stainless steel or other special corrosion - resistant materials.
Containing solid particles: If the liquid contains solid particles, a rotor - pump filling machine suitable for transporting liquids containing particles is required. The gap between the rotor and the pump casing of this type of pump is relatively large, which can avoid the blockage of the pump body by solid particles. At the same time, the wear resistance of the pump must be ensured to guarantee the service life of the equipment.
In terms of equipment performance:
Stability: Stability is an important factor in choosing a filling machine. When making a selection, you can learn about whether the structural design of the equipment is reasonable, whether the quality of the parts is reliable, and whether there are problems such as vibration and noise during the operation process. A filling machine with good stability can ensure continuous operation for a long time and reduce equipment failures and downtime.
Degree of automation: Select an appropriate degree of automation according to production requirements and budget. A filling machine with a high degree of automation can realize a series of operations such as automatic filling, sealing, and labeling, which can improve production efficiency and reduce manual operations, but the price is relatively high; while manual or semi - automatic filling machines require more manual intervention and are suitable for situations with small production scales or limited budgets.
Ease of cleaning: In industries such as food and medicine, the cleaning of equipment is very important. Choose a rotor - pump filling machine with a simple structure that is easy to disassemble and clean, which can facilitate daily cleaning and maintenance and ensure the hygiene and quality of the product.
In terms of equipment suppliers:
Brand reputation: Choosing well - known brands and suppliers with good reputations can ensure the quality of the equipment and after - sales service. You can learn about the reputation of the supplier through online searches, industry word - of - mouth, customer reviews, etc.
After - sales service: Good after - sales service is the guarantee for the normal operation of the equipment. Understand whether the after - sales service system of the supplier is perfect, including whether services such as equipment installation, commissioning, training, and repair are provided, as well as the response speed and quality of after - sales service.
Price: Price is also one of the factors to be considered when choosing a filling machine. Under the premise of ensuring the quality and performance of the equipment, choose equipment with a reasonable price. Do not just pursue low prices and ignore the quality of the equipment and after - sales service.
