Function: Pedal to extract liquid nitrogen
Note: The production batch is different, and the appearance of the product may be different, subject to delivery, if you mind, please contact customer service, thank you!
Precautions:
1: Due to the extremely low temperature of liquid nitrogen (-196°C), please wear protective gloves when operating.
2: The drain pipe should be slowly inserted into the liquid nitrogen container vertically to avoid puncturing the neck of the container.
3: If you are operating indoors, you should open the doors and windows to prevent the operating environment from lacking oxygen.
4: Since the temperature of liquid nitrogen is extremely low, the sealing ring is easy to be frozen and hardened. Please wait when you use it several times in a row.
Use after the sealing ring is reheated.
5: When draining liquid, condensation and water droplets on the external surface of the pump are normal phenomena, which are caused by the absorption of heat and vaporization of liquid nitrogen.
reason. After the liquid is drained, the water droplets on the pump body should be wiped dry to prevent moist air from entering the suction pipe and forming ice particles:
Block the bottom valve.
Troubleshooting questions:
1: Can't liquid nitrogen be discharged?
Reason: 1: The air release valve is not closed. 2: Ice is formed at the bottom valve of the suction pipe and the interface of the discharge pipe. Close the bleed valve.
Measures: 1: Close the air release valve. 2: Use a hair dryer or electric blower to melt the ice.
2: There is liquid nitrogen discharged but the discharge volume is small?
Reason: 1: The locking device is not tightly sealed. 2: There are ice particles between the suction pipe and the discharge pipe.
Measures: 1: Tighten the large and small nuts in the locking device. 2: Use a hair dryer or electric blower to melt the ice.
