During operation, every effort should be made to prevent surge from occurring； Ensure that the centrifugal compressor operates within its operating range (between S and E).

1. The pressure, temperature, and supply condition of the lubricating oil. The oil pressure must not be lower than 1 kilogram per square centimeter before it is fed into the distribution system. The oil temperature in the crankcase or engine compartment should be: no more than 60°C for compressors with crossheads. Those without crossheads shall not exceed 70°C. 2. Is the compressor running smoothly, and are the noises from the various moving parts normal? 3. Measure the inlet and outlet water temperatures and check the cooling water supply; the cooling water must not flow intermittently, and there should be no bubbles or blockages. The cooling water discharge temperature must not exceed 40°C. 4. All connection flange areas, shaft seals, intake and exhaust valves, cylinder heads, and water jackets must not leak air, oil, or water. 5. Check whether there is any looseness in the connection parts. 6. Measure whether the exhaust temperature and pressure values at each stage meet the requirements specified in the technical conditions
