1. liquid nitrogen tank accessories-liquid nitrogen pump
Liquid nitrogen pump is a kind of equipment for conveying and pressurizing liquid nitrogen. It can pump liquid nitrogen from the liquid nitrogen tank and pressurize it, and then transport it to the equipment through the pipeline. Liquid nitrogen pump usually consists of pump body, pump cover, shaft, seals and bearings, among which seals and bearings are key components and need regular maintenance and replacement.

2. Accessories of liquid nitrogen tank. Liquid level gauge
Liquid level gauge is a kind of equipment used to display the liquid level position of liquid nitrogen in liquid nitrogen storage tank. It can measure and display the liquid level position electronically or mechanically. The liquid nitrogen in the liquid nitrogen tank can be easily observed by using the liquid level meter, so as to replenish it in time.
3. Accessories of liquid nitrogen storage tank-safety valve
Safety valve is a kind of equipment used to protect the safety of liquid nitrogen storage tank, which can automatically open and release the pressure when the liquid nitrogen storage tank is abnormal, thus preventing the occurrence of safety accidents such as bursting or leakage. There are many kinds of safety valves, such as common safety valves, full-open safety valves, pulse safety valves, etc. It is necessary to choose the appropriate types and specifications according to actual needs.
4. Accessories of liquid nitrogen storage tank-pipeline
Pipeline is a kind of equipment used to connect the liquid nitrogen storage tank and the use equipment, which can extract the liquid nitrogen from the liquid nitrogen storage tank and transport it to the use equipment. Pipes need to be made of materials with good properties such as low temperature resistance, high pressure resistance and corrosion resistance, such as stainless steel and copper. At the same time, the pipeline needs to be cleaned and maintained regularly to ensure its smoothness and use effect.
5. Installation of liquid nitrogen tank-pressure gauge
Pressure gauge is a kind of equipment used to display the pressure in liquid nitrogen tank. It can measure and display pressure electronically or mechanically. The pressure in the liquid nitrogen tank can be easily observed by using the pressure gauge for timely adjustment and maintenance. At the same time, the pressure gauge is also one of the important reference indexes for the opening and closing of the safety valve.
6. Liquid nitrogen tank accessories-thermometer
Thermometer is a device used to measure the temperature of liquid nitrogen. It can measure and display temperature electronically or mechanically. The temperature of liquid nitrogen can be easily observed by thermometer for timely adjustment and maintenance. At the same time, the thermometer is also one of the important reference indexes to control the use speed of liquid nitrogen.
7. Accessories of liquid nitrogen storage tank-thermal insulation material
Thermal insulation material is used to keep the temperature of liquid nitrogen stable, which can isolate liquid nitrogen from the outside and reduce the heat transfer effect. Thermal insulation materials usually consist of thermal insulation layer and protective layer, in which the thermal insulation layer is usually made of perlite, calcium silicate and other materials, and the protective layer is made of metal plate or plastic plate.
