LNG Tank Truck — Troubleshooting
LNG tanker pressure too high
1. During loading, the LNG tanker tank is a hot tank.
LNG tanker pressure too high
2. Overpressure during filling
LNG tanker pressure too high
3. Overfilling
LNG tanker pressure too high
4. Prolonged parking leads to increased pressure.
LNG tanker pressure too high
5. Vacuum Loss
Unloading LNG from the tanker truck results in unstable pressure.
1. Inner cylinder safety valve leakage
Unloading LNG from the tanker truck results in unstable pressure.
2. Pressure increase too rapid
Unloading LNG from the tanker truck results in unstable pressure.
3. Rapid blood pressure reduction
Unloading LNG from the tanker truck results in unstable pressure.
4. Too Rapid a Drop in Blood Pressure
Unloading LNG from the tanker truck results in unstable pressure.
5. The tank truck pressure gauge is malfunctioning.
Vacuum loss
1. Opening of the interlayer explosion-proof cover
Vacuum loss
2. Local condensation and frost formation on the enclosure
Vacuum loss
3. The entire exterior is frosted.
The level gauge is not functioning properly.
1. Fluctuation of the level gauge pointer
The level gauge is not functioning properly.
2. The level gauge pointer has stopped moving.
The level gauge is not functioning properly.
3. The level gauge pointer swings back and forth.
The level gauge is not functioning properly.
4. The level gauge has not been zeroed.
The level gauge is not functioning properly.
5. The level gauge malfunctions or is damaged.
The emergency shut-off valve is not functioning properly.
Frost formation in the pipeline under static conditions
1. Valve Leakage
