Matters needing attention in the process of welding insulated gas cylinder

Precautions for the use of welded insulated cylinders

1, each valve switch should light open light shut, forbid excessive force tight death.

When the 1.1 outlet valve is opened, 1-1 turns can be rotated to meet the working requirements of the engine. Stop the vehicle when the liquid outlet valve should be closed.

1.2 the normal operation of the vehicle, only need to open the outlet valve, other valves are in the closed state.

2, buffer tank pressure should be adjusted according to the working requirements of the engine (heavy duty engine: D615 and D12 supply pressure 0.6-08MPa, MT07 gas supply pressure 0.55-0.6MPa).

3. The pressure of the welding insulated cylinder is higher than 0.1-0.3 MPa of the buffer tank.

4, one or two class safety valve factory standards are not the same, so you should pay attention to check the valve body on the valve after the calibration of the pressure value, do not rely on experience to determine, so as to avoid misjudgment.

5, when the welding pressure insufficient insulation cylinder should open pressurization system to be welded insulated cylinder should be closed when the pressure reaches the demand pressure valve (special requirements such as overloading the long climb sustainable intensification). Special tips: suspended after the vehicle should be closed immediately to prevent pressure valve, pressurization system of continuous pressure caused by high pressure welding insulation cylinder exhaust.

7, regular inspection (10-15 days) gas cylinders, pipelines, valves, pressure gauges and other parts of the connection is the phenomenon of leakage.

8, keep the welding insulation cylinder cleaning, regular inspection and cleaning of welding and freezing insulation cylinder on the pipeline (long time continuous running without stopping should pay special attention to check the cleaning), don't use hot water.

9, LNG is ultra-low temperature liquid, should pay attention to don't splash on the body, simple maintenance should pay attention to the protection measures.

10, long time before parking should minimize the welding insulation cylinder LNG to reduce the loss, again before the operation of the vehicle to deal with welding insulation cylinder inspection, start the vehicle.
