Small liquid nitrogen machine, a simple plug and play solution for liquid nitrogen. Based on the cold head process, helium gas compression and expansion are combined to achieve low temperature cooling. Built in oil free air compressor, PSA pressure swing adsorption nitrogen generator, refrigeratory, helium compressor and Dewar tank, fully automatic operation.
Small liquid nitrogen machine is a simple plug and play solution for liquid nitrogen field. It is compact and low noise. It is very suitable for laboratories, hospitals, medical centers and other places. It is the preferred supporting equipment for energy spectrometer, nuclear magnetic resonance equipment, living cell freezing and so on.
Reliability is good. The material is air. The unique refrigeration technology extracts liquid nitrogen.
It is convenient and fast, and can be taken from storage tank at any time, so as to avoid being unable to take it out because of insufficient pressure of liquid nitrogen tower.
High safety, self induction connection of storage tank, and real-time capacity monitoring to prevent overflow.
The operation is simple, the operation panel has rich functions and is intuitive and clear.
1. Cost of investment 2. Cost of use and daily maintenance 3. Stability of equipment system is guaranteed to a certain extent 4. Advanced manufacturing technology 5. Integration of production, sales and maintenance
1. Normal supply of power supply, gas source and temperature conditions required by the machine and normal opening and closing; especially the stability of power supply voltage, nitrogen machine, reduce the damage to the controller and solenoid valve caused by power supply problems.
2. Always pay attention to the pressure of the air storage tank. Keep the pressure of the air storage tank between 0.7 MPA and 0.75 MPA. Do not lower than the rated value.
3. Check the automatic drain every day to avoid blocking and losing drainage function. If blocked, slightly open the manual valve, close the self draining valve and remove the automatic drain, decomposition and cleaning. When cleaning the automatic drain, soap foam can be used to clean it. Strictly prohibit the use of gasoline, toluene, pine perfume and other corrosive solutions.
4. Operators should regularly inspect the three pressure gauges on the machine, make a daily record of their pressure changes for equipment failure analysis, and observe the flow meter and nitrogen purity at any time, so as to maintain the nitrogen purity of the exhaust gas.
5. Operate and maintain the instrument according to the requirements of the code of use. Check the sensitivity of solenoid valve/pneumatic valve, the pressure range of pressure regulating valve, the precision of gas analyzer, the pressure of adsorption culture, the exhaust condition of muffler, the cleanliness of inner tube of flowmeter, etc. from time to time.
Widely used in non ferrous metal heat treatment, chemical industry, rubber industry, pharmaceutical industry, food industry, metallurgical industry, electronic industry, glass industry, coal industry, aerospace technology support, petroleum industry, plastics industry, textile industry and other industries and fields.
