How to control the temperature of high temperature melt gear pump

The temperature and pressure control of high-temperature melt gear pump, is mainly by means of detection technology and automatic control technology, based on inverter, high temperature melt pressure sensor, solid state power controller, intelligent digital display controller composed of temperature and pressure control system. The system has good reliability, continuity, safety, and its application will further improve the level of automation control injection molding system.
gear pump

The temperature control is mainly the detection of temperature, temperature detection of the specific program is the introduction of high temperature melt gear pump temperature sensor installed on the pump material for real-time detection, and the measured signal through a self-tuning with PID adjustment Device operation, the output 4-20mA standard current control solid-state power control devices, thereby changing the heater power to achieve the effect of temperature control. The material temperature is maintained at the process requirements 値. For the material flowing out of the pump body, due to the pump delivery and pressure, the temperature will change, so in the part near the discharge port with a temperature sensor to detect it, and then the measured signal through a PID Self-tuning regulator operation, the output 4-20 mA standard current control of solid-state power control devices, thereby changing the power with the tropical zone, to achieve the effect of the temperature control.
