3.jpg Participation: Prize of 5 Wealth; Correct answer: Reward of 10 wealth points ; Note: This post is valid for 48 hours. Question: What is the function of the electro-hydraulic converter in the turbine speed control mechanism of the (DMTO) olefin separation unit? The signal that converts the control commands sent by the electrical control device into hydraulic signals, as well as amplifies those signals, is known as an electro-hydraulic conversion signal. It is a key component in the electro-hydraulic control system. The function of the electro-hydraulic converter is to convert electrical signals into hydraulic signals, that is, to transform the output current from the electronic speed controller into secondary oil pressure. This secondary oil pressure is then used, through an amplifying actuator, to control and adjust the opening degree of the control valve. Note: The answers will be announced automatically in two days!

The 4-20MA signal from the electronic governor DDV valve is converted into a hydraulic signal, which is then supplied to the power cylinder in order to control the main valves and thus regulate the turbine speed.

The voltage signal from the turbine is converted into a hydraulic signal for the oil-driven motor, which is used to control the stroke of the motor; this in turn adjusts the opening degree of the control valve, altering the air intake to the turbine and thus regulating its speed.
