MVR steam compressor reconstruction program: MVR steam compressor in the automatic according to the temperature and negative pressure to adjust the two VFDs, induced wind VFD automatically according to the pressure transmitter feedback to the PLC pressure signal, and on the touch screen The pressure value, PLC automatically adjusts the output frequency to control the speed of the VFD to keep the negative pressure constant. In the two sets of oil supply circuits, according to the pressure change values of the oil return and oil return during automatic control, to determine the external load conditions, the pressure is automatically adjusted. When the pressure of the oil is greater than the pressure of the return oil, the pressure is within a certain range. Within it, the frequency of the frequency converter can be automatically increased by operation of the PLC. If the output of the frequency converter reaches full load, another set of oil supply circuits is automatically started to ensure the need for production; conversely, if the output pressure is close to the pressure of the circuit , Automatically cut off a set of oil supply circuit, reduce the frequency, while ensuring production, to achieve the effect of energy saving. MVR steam compressor temperature below 40 ℃, material selection 2205 #, duplex stainless steel, temperature 40 ℃~ 90 ℃, material selection 2507 #, duplex stainless steel, temperature above 90 ℃, material selection 254SMo or titanium material. The above simple analysis of the MVR steam compressor reform program.
