Maintenance and Care of the Gas Pipeline


For air compressors, the oil level must be maintained at or above the minimum mark during operation. Relevant personnel shall conduct regular inspections of the oil level and the quality of the lubricating oil, and replace or top up the oil as necessary based on actual conditions. In addition, No. 19 compressor oil should be used in summer, while No. 13 compressor oil is recommended for winter. The air compressor should be placed on a level, clean surface, and the operating environment must be free from moisture and dust. Condensate in the air receiver tank should be drained every two shifts to ensure the proper functioning of the safety valve; furthermore, the safety valve should be inspected regularly—approximately once every three months—and the silencer should be cleaned every 250 operating hours.
