Principle of oil temperature control Unit

  • The method of changing the control set value can respond to the system lag in the process as quickly as possible and obtain a smaller system overshoot. The control consists of two sets of PID control loops, which are called: main loop and slave loop. The control output of the main loop is used as the set value of the slave loop. By controlling the temperature change gradient in this way, the temperature control accuracy of the system is guaranteed.
  • The specially designed hysteresis predictor generates a dynamic signal yc(t) instead of the process variable y(t) as a feedback signal. Generate an e(t) signal for the controller, so that the controller predicts that the control action has no large lag.

Oil temperature control units are devices designed to precisely regulate oil temperatures, and they are commonly used in both industrial production and laboratory settings. These units maintain specific temperatures by heating or cooling the oil, ensuring process stability and the quality of the final products.

Please consider various factors, such as the required temperature range, heat load, temperature control accuracy, heat transfer fluid type, system compatibility, and any specific requirements such as sustainability.
If you want to know exactly which one is suitable, please contact us now and our engineers will provide you with professional consultation and advice.

Oil circulating temperature control units play a crucial role in maintaining the efficiency and longevity of industrial equipment. Here’s why they are essential:

  •  Temperature Regulation: In many industrial processes, oil serves multiple functions, such as lubrication, power transmission, or as a heat transfer medium. However, during operation, oil tends to heat up due to mechanical friction, electrical resistance, or the heat generated by the process itself.
  • Prevention of Issues: If the oil temperature rises beyond a certain level, it can cause various problems:
  •     Reduced lubrication: Higher temperatures can degrade the oil’s lubricating properties.
  •     Increased wear: Excessive heat accelerates mechanical wear and tear.
  •     Equipment failure: Overheated oil can lead to breakdowns or malfunctions of machinery.
  • Optimal Performance: Oil circulating temperature control units are designed to remove excess heat from the oil, ensuring it remains within the optimal temperature range. This helps to prevent the issues mentioned above and ensures smooth, efficient operation.
  • Process Stability and Product Quality: These units also help maintain process stability and ensure consistent product quality by regulating the oil temperature through either heating or cooling.

By effectively controlling the oil temperature, these units help optimize industrial processes and extend the life of equipment.
