Working medium of LNG refueling machine: LNG refueling speed: 3 ~ 80kg/min Metering accuracy: 1.0 grade repeatability: 0.5% Working pressure: 1.6MPa Design temperature: -196℃ ~ 55℃ Vacuum module design high brightness large screen display, adjustable measurement unit Double break protection Standard vacuum refueling hose optional explosion-proof small standard printer metal keyboard configuration. The following LNG refueling equipment manufacturer will introduce the precautions for the use of LNG refueling machine to you:

1. Before the refueling machine is powered on each time, check whether the instrument air pressure is enough (> 0.4Mpa).

2. After the refueling machine is powered on, the small circulation valve should start, except for those specially set; The display should show the data of the last refueling. The screen next to the keypad should show free filling.

3. Large cycle pre-cooling should be carried out as little as possible. It can be determined according to the situation of defrosting or the ambient temperature.

4. The flowmeter of the refueling machine is the mass flowmeter. The solid part is not vacuum, and the inner part is filled with inert gas, so frost will form when working for a long time. However, it is not recommended to keep the flow meter warm, otherwise it will affect the measurement accuracy.

5. Before each operation of the nozzle, it should be purge first, especially the ice slag and foreign bodies at the inner sealing ring, which can easily damage the sealing ring and shorten the life of the sealing ring.

6. The nozzle sealing pad is easy to be damaged and the cost is high. During operation, both hands should exert balanced force, first relieve pressure, and then press the handle smoothly and pull it out.

7. When the inner sealing pad of the nozzle is damaged, the leakage phenomenon will occur when the nozzle is pulled out; If there is leakage when adding liquid, the outer sealing ring is generally damaged. The outer sealing ring is more easily damaged than the inner sealing gasket. When the inner sealing gasket is damaged, it is easy to hurt people.

8. The service life of the sealing ring and pad of the refueling gun is calculated by the number of times, so the number of plugging and unplugging of the refueling gun can be reduced as far as possible. When not in use, the gun can be placed in the buckle, not inserted in the holder of the refueling machine. The above content is the introduction of 8-point LNG refueling equipment manufacturers for you to pay attention to the use of LNG refueling equipment, I hope to help you.
