Description
1) Check whether the main screw connection of the compressor and the anchor bolts are secure; 6MPa 2) Check whether the compressor electrical and instrument lines are connected correctly and securely and whether the instruments can work normally; 3) Open the control air source of the unloading valve Instrument air, confirm that the outlet valve and vent valve are closed (if replacement is required after replacement); 4) confirm that the local parameter display is consistent with the display of the central control room; 5) confirm that one-time one, two-time one, PV01201 and front and rear hand valves 、 V01204A / B 、 All safety valve root valves and valves are fully opened; confirm that the pipeline and all safety valve root valves and valves are fully opened; confirm that the pipeline and equipment are down and beside the safety valve The road valve and compressor outlet valve (V01202A / B) are fully closed. 6) Confirm that the on-site operation column transfer switch is in the “manual” state; 7) If the motor is replaced or repaired, check that the rotation of the motor (facing the motor clockwise) is correct;
Preparation before starting the raw gas compressor
1) Check whether the main screw connection parts of the compressor and anchor bolts are secure; 6MPa
2) Check whether the compressor electrical and instrument lines are connected correctly and securely, and whether the instruments can work normally;
3) Open the control air source instrument air of the unloading valve, and confirm that the outlet valve and vent valve are closed (if the maintenance is completed, it needs to be replaced);
4) Confirm that the local parameter display is consistent with that of the central control room;
5) Make sure that one back one, two back one, PV01201 and front and rear hand valves, V01204A / B, and all safety valve root valves and valves are fully open; confirm the pipeline and all safety valve root valves and valves The valve is fully open; make sure that the pipelines and equipment fall down, the safety valve bypass valve, and the compressor outlet valve (V01202A / B) are fully closed.
6) Confirm that the field operation column transfer switch is in the “manual” state;
7) If the motor is replaced or repaired, check that the rotation of the motor (facing the motor clockwise) is correct;
