The impact of the accuracy of the pressure sensor on the plastic extrusion machinery is reflected in the following aspects:
1. Product quality control: high-precision pressure sensor can more accurately reflect the pressure changes in the extrusion process. This helps to ensure consistency in the physical properties, dimensional accuracy and appearance quality of plastic products. For example, when producing plastic film, small pressure fluctuations can lead to uneven film thickness, and if the pressure sensor is not accurate enough, these fluctuations cannot be detected and adjusted in time, thus affecting product quality.
2. Process parameter adjustment: The accurate data provided by the high precision pressure sensor allows the operator to adjust the process parameters of the extruder more accurately, such as screw speed, heating temperature and extrusion speed. If the sensor accuracy is low, it may lead to a deviation in the judgment of pressure, so that the adjusted process parameters are inaccurate, affecting the production efficiency and product quality.
3. Equipment performance evaluation: Through the accurate monitoring of pressure data, the performance and working status of the extruder can be more accurately evaluated. For example, determine the wear of the screw and barrel. Sensors with insufficient accuracy may not be able to detect pressure changes due to wear in a timely manner, delaying maintenance and repair of equipment and increasing the risk of equipment failure.
4. Energy consumption management: Accurate pressure measurement helps to optimize the energy consumption of the extruder. If the accuracy of the pressure sensor is poor, it may lead to waste of energy or insufficient supply. For example, failure to detect and reduce power when the pressure is too high, or failure to increase power in time when the pressure is too low, will affect the effective use of energy.
5. Cost control: High-precision pressure sensors can reduce the generation of waste and defective products, reduce the waste of raw materials, thereby reducing production costs. On the contrary, sensors with low accuracy may lead to more substandard products and increase production costs.
6. Production stability: Accurate pressure monitoring helps to maintain the stability of the extrusion process. Inadequate pressure sensor accuracy can lead to frequent production fluctuations, affecting the normal operation of the entire production line and increasing the number of production interruptions and restarts.
