Inspection steps before commissioning liquefied gas compressor

Inspection steps before commissioning liquefied gas compressor

(1) Check whether the compressor crankcase is filled with lubricating oil. The oil level should be at the upper mark of the sight glass. The brand of lubricating oil is: L-DAB100 compressor oil in winter and L-DAB150 compressor oil in summer.

(2) Check whether the connection parts are loose;

(3) Whether the tightness of the triangle belt is appropriate;

(4) Whether the wiring of the explosion-proof motor is correct and whether the grounding wire is in good condition;

(5) Whether the handle of the 2-position 4-way valve is in the correct position (determined according to the operating requirements);

(6) Whether the connection of pipelines and valves is correct, the gas phase pipe is not allowed to be connected with the liquid phase pipe;

(7) Whether the vent pipes on the compressor unit are installed correctly;

(8) Turn the compressor flywheel and listen carefully for any abnormal sounds inside the liquefied gas compressor;

(9) Refer to the instructions in Section 5 of Chapter 3 to start the explosion-proof motor to rotate and check whether the rotation direction is correct. The correct rotation direction is: when a person stands at the flywheel end and looks toward the liquefied gas compressor, the flywheel should rotate counterclockwise.

(10) After the hydraulic pressure test of a newly built station, water will remain in the gas pipeline, which should be drained. Otherwise, the water will cause the compressor to stop automatically.
