The LNG gasification skid is mainly composed of LNG vaporizer, LNG unloading supercharger, BOG heater, EAG heater, water bath electric heater, valve, pressure regulator, flow meter, shut-off valve, safety relief valve, odorizer Its main function is to provide a stable and reliable air supply system.
LNG gasification skid maintenance work:
1. Regularly check whether the outlet pressure of the regulator can meet the working requirements. If there is any abnormal phenomenon, check and maintain it in time.
2. Regularly check the closing pressure of the regulator. If the closing pressure is too high or there is air leakage, check whether the main valve of the regulator and the membrane of the pilot are aging or damaged and clean the valve port of the regulator.
3. Regularly check the cut-off pressure of the cut-off valve. If the cut-off pressure is too low, check whether the spring loses its strength or is broken and re-adjust the cut-off valve; if the cut-off pressure is too high or leaks, check whether the cut-off valve membrane is aged and damaged. Regularly check the closing characteristics of the shut-off valve. If the shut-off is not tight after cutting off, check and clean the shut-off valve port.
4. Regularly check the condition of the safety relief valve and the relief pressure. If the release pressure of the safety release valve is too low or leaks, check whether the film of the safety release valve is aging or damaged, whether the spring loses its strength or is broken, and clean the valve port of the release valve; if the release pressure is too high, readjust the safety release valve. valve.
5. Regularly replace the pressure regulator, shut-off valve, and safety relief valve membrane, and the cycle should be determined by the quality of the gas.
6. Open the drain valve on the filter regularly to discharge the dirt.
7. Clean the filter element regularly.
