Price advantage of 50 cubic meter buried storage tank manufacturer for A2 level LPG storage tank

Description :

Unloading operation

　　1. After the tanker enters the designated position, turn off the engine, tighten the manual brake, and use a triangular wooden block to prevent the tanker from sliding.

　　2. Check whether the tank body, valves, level gauges, pressure gauges, and thermometers of the tanker are normal, and whether the fire-fighting equipment is intact and ready for use.

　　3. The static grounding wire between the tanker and the unloading platform should be firmly connected, and the liquid level of the tanker should be calibrated and recorded together with the tanker escort.

　　4. The gas and liquid hoses of the unloading platform are firmly connected to the quick connector of the tanker. Before connection, the sealing rubber ring should be checked to ensure that it is in good condition

　　5. Press the handle of the tanker oil pump to increase the oil pressure to 0.3-0.4MPa, in order to open the emergency shut-off valves for the gas and liquid phases of the tanker.

　　6. Open the vent angle valve, release the air from the hose, and close the angle valve after the gas and liquid phase materials are sprayed out.

　　7. Open the pneumatic and liquid-phase valves of the tank driver.

　　8. Open all valves on the liquid phase pipeline from the storage tank to the tanker.

　　9. Send air to the pneumatic cut-off valve of the storage tank, keeping it in the open position, to connect the gas phase port of the storage tank with the gas phase port of the tanker.

　　10. After inspection and confirmation, turn on the unloading pump and enter the tank. The tanker is in the unloading state.

　　11. During the unloading process, it is strictly prohibited to overfill the storage tank, and the unloading speed should not be too fast. The pressure difference between the tanker and the storage tank should not exceed 0.2 MPa.

　　12. Unloading is completed, stop the unloading pump, close the gas and liquid phase valves of the storage tank, manually operate the solenoid valve to urgently cut off the gas phase and return to the closed state. Close the emergency shut-off valve and gas-liquid phase valve of the tanker.

　　13. Open the exhaust valve of the tanker and exhaust any residual gas in the unloading hose.

　　14. Remove the hose and disconnect the static grounding wire between the tanker and the loading and unloading platform, and close the tanker operation box.

　　15. Verify the liquid level after unloading and sign the unloading operation record with the escort.

　　16. Inspect the site and ventilate for 5-10 minutes before starting the vehicle.

　　17. When thunderstorms, nearby fires, gas leaks, abnormal pressure, and other unsafe factors occur, loading and unloading operations should be immediately stopped.

Filling operation1. Open all valves in the liquid phase pipeline between the outlet and the gas dispenser, and open all valves in the reflux pipeline.

　　2. Provide pneumatic cut-off valve for liquid gas supply, keep it in the open position, and connect the storage tank with the filling pump.

　　3. After confirming the status of each valve, turn on the filling pump.

　　4. Determine whether the return pipeline is in working condition based on the working status of the gas dispenser. When the usage of the gas dispenser is low, the pressure will cause the safety reflux valve to open and return to the storage tank through the reflux pipeline

　　5. For specific car refueling operations, please refer to the refueling machine operation guide.

　　6. Stop the refueling pump after refueling is completed. If the gas is not refilled for a long time, the emergency shut-off valve at the liquid outlet should be closed.
