Temperature and Environmental Factors
Influence of Temperature:
The viscosity of whitening agents will change with temperature variations. For example, at lower temperatures, the viscosity of some whitening agents may increase significantly, which will affect the smoothness of the filling process. For high-precision filling machines equipped with servo magnetic gear pumps, changes in viscosity may lead to a decrease in the filling speed or a reduction in filling accuracy. If the temperature is too low, the whitening agent may even solidify, completely blocking the filling pipes and the pump body.
Extreme temperatures will also have an impact on the electronic components of the filling machine. In a high-temperature environment, the electronic components may activate the overheating protection mechanism, causing the machine to stop running or malfunction. In a low-temperature environment, the performance of the battery (if there is a battery-powered part) may decline, and the sensitivity of some sensors may also be affected, thereby influencing the automated control of the filling process.
Humidity and Dust:
A high-humidity environment may cause the metal parts of the filling machine to rust, especially those parts that have not been properly protected. For filling machines used for whitening agents containing corrosive components, rusting will further exacerbate the corrosion degree of the parts, affecting the service life and performance of the machine.
When dust enters the interior of the filling machine, it may accumulate on key components such as motors and gears. For the servo magnetic gear pump, dust may interfere with the normal meshing of the gears, increase friction, lead to intensified wear of the components, and may also affect the sealing performance of the pump, reduce the filling efficiency, and even cause problems such as leakage.
Chemical Properties of Whitening Agents
Acidity and Alkalinity (pH Value):
Different whitening agents have different acid-base properties. If the contact parts of the filling machine (such as the pump body, pipes, nozzles, etc.) cannot withstand the pH value of the whitening agent, chemical reactions will occur. For example, a whitening agent with strong acidity may corrode metal parts, while a whitening agent with strong alkalinity may erode certain plastic parts. Such chemical corrosion will cause damage to the components, affect the normal operation and performance of the filling machine, and may also contaminate the whitening agent.
Chemically Active Components:
Some whitening agents contain active components that may react chemically with the materials of the filling machine parts, such as redox reactions. If the materials of the filling machine are improperly selected, these reactions may cause phenomena such as deterioration and peeling on the surface of the parts. For example, a whitening agent containing a strong oxidizing agent may cause rubber seals to age and harden, thus losing their sealing performance and leading to leakage problems.
Overall Structural Design of the Filling Machine
Pipeline Layout and Inner Diameter:
Whether the pipeline layout of the filling machine is reasonable directly affects the flow resistance of the whitening agent. If there are too many bends in the pipeline or sudden changes in the pipe diameter, the resistance to liquid flow will increase, resulting in uneven filling speeds or unstable filling pressures. For example, in some complex multi-station filling machines, an unreasonable pipeline design may cause the flow rate at the filling heads far from the pump body to be significantly smaller than that at the filling heads close to the pump body, affecting the overall filling accuracy.
The size of the inner diameter of the pipeline is also crucial. If the inner diameter is too small, for high-viscosity whitening agents, relatively large flow resistance may be generated, and even blockage may occur; if the inner diameter is too large, for low-viscosity whitening agents, it may be difficult to control the filling accuracy because the flow velocity and flow rate of the whitening agent in the pipeline are difficult to adjust precisely.
Design of the Filling Head:
The shape and size of the filling head have an important impact on the filling effect. Different shapes of filling heads are suitable for different types of containers and whitening agents. For example, for containers with small bottle mouths, it is necessary to design filling heads that are slender and have an appropriate outlet shape to ensure that the whitening agent can be accurately filled into the containers without splashing out.
The material of the filling head is also very important. For some volatile or corrosive whitening agents, it is necessary to use materials that are corrosion-resistant and have good sealing properties to make the filling heads, so as to prevent the whitening agent from leaking or volatilizing and at the same time ensure the filling accuracy.
Complexity and Stability of the Control System
Program Algorithms and Logic:
The program algorithms adopted by the control system of the filling machine determine its control accuracy for various filling parameters. For example, advanced algorithms can adjust the filling speed and filling volume in real time according to multiple factors such as the viscosity of the whitening agent, temperature, and container size. If the algorithms are not precise enough or do not take all influencing factors into account, the filling accuracy will decline.
Whether the logic of the control system is reasonable is also very important. For example, when dealing with multi-station filling or filling containers of different specifications, a control system with clear logic can accurately allocate filling tasks and avoid filling confusion or errors.
Quality of Electronic Components and Anti-interference Ability:
The quality of the electronic components in the control system directly affects the stability of the system. Low-quality electronic components are prone to malfunctions, such as sensor failures and controller crashes. In an industrial environment, there are various sources of electromagnetic interference, such as electromagnetic interference generated by motor operation and radio waves from nearby other equipment. If the electronic components of the filling machine control system have poor anti-interference ability, signal errors, data loss and other problems will occur, affecting the performance of the filling machine.
