Common Issues and Countermeasures for Liquid Filling in High-Temperature Summer Environments
In summer or when workshop temperatures are excessively high, the viscosity and density of liquid materials may change, while equipment components may deform due to heat. This can easily lead to problems such as decreased filling accuracy, increased foaming, and unstable discharge. The following analysis covers both material and equipment aspects, along with corresponding solutions.
I. Material-Level Effects
High temperatures reduce liquid viscosity and increase fluidity, resulting in greater discharge volume within the same filling time. For low-viscosity materials, high temperatures may also cause foaming and volatilization, which can alter filling capacity and affect accuracy.
II. Equipment-Level Effects
Seals and O-rings may soften and deform due to heat, leading to reduced sealing performance and potential leakage. Electronic control components may experience parameter drift under high temperatures, and sensor sensitivity may become abnormal, affecting stable equipment operation.
III. Countermeasures
Control Ambient Temperature: Install cooling and ventilation equipment in the workshop to properly control the working environment temperature, and avoid prolonged high-temperature exposure of both equipment and materials.
Store Materials at Constant Temperature: Store materials in a temperature-controlled environment in advance. Allow them to cool down before filling to ensure consistent material temperature.
Recalibrate Filling Parameters: In high-temperature conditions, recalibrate filling parameters, fine-tuning filling duration, flow rate, and suction force to adapt to changes in material characteristics.
Replace with High-Temperature-Resistant Seals: Use sealing components that can withstand high temperatures to prevent leakage caused by thermal deformation.
Ensure Proper Cooling of the Control System: Regularly clean the cooling fans of the electrical control cabinet to maintain good heat dissipation and prevent parameter drift.
Increase Inspection Frequency: During high-temperature production periods, increase the frequency of random sampling to detect and correct accuracy deviations promptly, ensuring stable filling quality.
