The control system of the regenerative compressor adopts a step-down start and an alarm interlock system. The paperless recorder, explosion-proof operation box, junction box and pressure transmitter are integrated in the local instrument control cabinet. After the compressor runs normally, if there is a fault and it stops automatically, the operator can press the alarm reset button to eliminate the alarm, and then according to the alarm shutdown indication content, the fault can be restarted after the fault is removed. It is worth mentioning that when the compressor is in normal operation, if the external disturbance enters the system lubricating oil pressure, the lubricating oil pressure low alarm occurs and the interlocking value is not reached, that is, the oil pressure is 0.15~0.20MPa, the lubricating oil auxiliary pump is self-pumping. start up. In view of the safety considerations of the unit, it is considered that the main oil pump or the paperless recorder malfunctions, so the auxiliary pump continues to operate to maintain the oil pressure, even if the "auxiliary pump stop" switch is used in the explosion-proof operation box panel. The only solution is to stop the compressor and check it again and then reboot. The paperless recorder realizes the functions of collecting the pressure and temperature signals of the field instruments; realizing the power distribution function of the pressure transmitter; realizing the interlocking contact output of temperature and pressure alarm; parameter trend and historical data storage. All temperature measurement points on the site come from the thermal resistance (Pt100), and the pressure measurement point signal comes from the pressure transmitter.
