【Daily Question No. 299】November 1, 2018: Briefly describe the main contents of the routine inspections for reciprocating compressor operators (1) Noise: Carefully analyze whether there are any abnormal noises from the operating unit. (2) Vibration: Touch and listen to the operating components of the unit to check for vibration. (3) Temperature: Check the temperature indicator, and touch the air valve as well as those areas without temperature indicators to verify that the temperatures of all parts are normal. (4) Lubrication: Check the lubrication condition of the crankcase, packing, and cylinders. (5) Pressure: Check the outlet pressure at each stage as well as the pressure of the cooling water and lubricating oil. (6) Power supply: check current, voltage, and other conditions. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

The daily inspection of reciprocating compressors is divided into three parts: the main unit, the drive equipment, and the auxiliary equipment. The main unit checks the inlet and outlet pressures and temperatures at each stage of the compressor ； Pressure and temperature of lubricating oil at various lubrication points ； Are there any leaks in the connection pipelines at all levels? ； Is there any abnormal noise, overheating, or vibration in the compressor itself? ； Are all connection points secure, and are the bolts tight? ； Are all control valves functioning properly? ； Is the seal gas pressure normal? ； For the motor of the drive device, it is necessary to check the motor current and temperature, as well as whether the temperature of the motor bearings is normal ； Auxiliary equipment such as the lubricating oil station is mainly used to check the oil level in the tank and whether the oil pump is functioning properly. . . .

Check that the cooling water discharge temperature is ≤37～40℃. 3. Check the temperature of the lubricating oil in the engine’s oil sump; it should not exceed 60°C. 4. Check the temperature of the spindle bearing pads; it should not exceed 70°C. 5. Check the exhaust temperature; it should not exceed the set value. 6. Check the exhaust pressure; it should not exceed the set value. 7. Check whether the instruments in the automatic control section are functioning properly ； Is the ammeter reading normal? 8. Check whether the intake valve cover is hot and whether the sound of the valve is normal. 9. Pay attention to listening for any abnormal noises or impacts as the various components operate. 10. Eliminate oil, water, and air leaks in all areas. 11. Keep records of the compressor’s operating conditions.
