Name: Small integrated liquid nitrogen machine (mixed working fluid)
Product name: Weidejie
Model: WDJ-LN10L-A
Daily output: 8L-15L
1. Technical scheme:
Liquid nitrogen generator (liquid nitrogen machine) equipment consists of nitrogen generator (built-in or external), refrigeration equipment (gas liquefaction equipment) and Dewar tank. The whole machine has a one-key start-up automatic refilling function. When the liquid nitrogen in the liquid nitrogen tank is lower than the set liquid level, the device automatically starts. The manufacture of liquid nitrogen machine adopts the principle of throttling refrigeration of mixed working medium, which cools nitrogen from ambient temperature to the saturation condensation temperature of nitrogen liquefaction step by step. To store in the liquid nitrogen tank to obtain liquid nitrogen, the equipment automatically detects the liquid nitrogen level in the Dewar tank, and automatically controls the operation of the equipment.
Second, the main configuration:
1. The compressor adopts German fully enclosed low temperature refrigeration compressor.
2. Liquid nitrogen level sensor: Mike automation instrument.
3. Dewar: Weidejie.
4. Electric control part: PLC
5. Independently design and develop man-machine interface control system.
6. Refrigeration accessories are all world-renowned brands: Japan Saginata solenoid valve, Danfoss throttle valve,
Danvers filter, etc.;
7. PT100 platinum resistance and T-type thermocouple are used for temperature detection, both of which have high reliability and long-term stability.
