The thermal balance control of the underwater pelletizing verification machine is a complex and critical process, which mainly involves the effective monitoring and regulation of the temperature during the pelletizing process.1. Temperature monitoringApplication of temperature sensors: Temperature sensors are installed in key parts of the pelletizer, such as the pelletizing chamber, cooler, etc., to monitor temperature changes in real time. These sensors convert temperature signals into electrical signals and transmit them to the control system to provide a basis for subsequent adjustments.Temperature display and alarm: The control system receives and processes the signal of the temperature sensor and displays the temperature value on the operation interface for the operator to monitor. When the temperature exceeds the set range, the system will issue an alarm signal to remind the operator to take timely measures.2. Temperature regulationCooling water temperature control: Cooling water is sent to the cooler through a circulating pump to cool the pelletizing water. The cooling water temperature control system includes components such as cooling water control valve, temperature transmitter, and control module. The temperature transmitter monitors the cooling water temperature in real time and transmits the signal to the control module. The control module controls the flow of cooling water by adjusting the opening of the cooling water control valve according to the preset temperature value, thereby achieving precise adjustment of the cooling water temperature.Pelletizing chamber temperature control: The temperature in the pelletizing chamber is mainly affected by the molten resin and cooling water. The temperature in the pelletizing chamber can be controlled by adjusting the extrusion speed of the molten resin and the flow of cooling water. The extrusion speed of the molten resin can be adjusted by the screw speed, while the flow of cooling water can be achieved through the cooling water control system.3. Realization of thermal balanceOptimization of the feed and retract system: The feed system plays a key role in the smooth operation of the unit and the force coordination between the cutter and the template. By adding a retractor to the feed system, a reverse force is achieved to balance the propulsion force of the feed system, so that the cutter always maintains a slightly positive pressure working state on the template. This optimization can not only improve product quality, but also reduce the loss of wearing parts and reduce the number of unit failure shutdowns.Optimization of the cooling system: The optimization of the cooling system mainly involves the improvement of the cooling water circulation system and the precise control of the cooling water temperature. By improving the cooling water circulation system, the utilization efficiency of cooling water can be improved and energy consumption can be reduced. By accurately controlling the cooling water temperature, the thermal balance in the pelletizing process can be ensured to avoid damage to product quality and equipment caused by excessively high or low temperatures.Application of automatic control system: The automatic control system is the key to achieving thermal balance control. By collecting signals from temperature sensors, pressure sensors and other equipment, the temperature, pressure and other parameters in the pelletizing process can be monitored in real time. According to the preset control strategy, the cooling water control valve, screw speed and other equipment are automatically adjusted to achieve precise control of the pelletizing process.In summary, the thermal balance control of the underwater pelletizing verification machine is completed through temperature monitoring, temperature regulation and thermal balance realization. These measures jointly ensure the temperature stability in the pelletizing process, thereby ensuring product quality and production efficiency.
