Product Description
1.) Air compressor
Air compressor is micro oil screw compressor, it have low noise, whole machine gather gas, lubricate, water, electric, cooling and instrument to one, realize machine and electric become one body. Control system adopt PLC controller, touch-way panel may provide the supervision of all adjustment of parameter and critical running parameter, also have alternative Chinese and English liquid crystal display, have full protection function, may realize no-person operate.
2). Pre-cooling system
It adopt full-close imported compressor, refrigeration agent will never leak out, high-efficiency steam-water separator and imported automatic drain water machine, ensure the outlet haven't liquid water. Refrigeration component is imported from Denmark Danfoos, the plant can run continuously all the year, it have long live. In the plant, equipped long-distance signal connecting point of air Inlet temperature, Long-distance signal of start and stop machine and running trouble signal, it is convenient for user's interlock supervision. The unit is box-body construction, on foundation installation, easy to construct.
3). Purifier
The unit is composed of two vessels: one is on heating while the other being regenerated; ensure the air's clear to cold box, length the running period of rectification column. Use of impurity nitrogen to heat for regenerated and also automatic control the heat temperature.
4). Booster Turbine Expander
Booster Turbine Expander is combine produced by our factory and Cryogenic Center of China Academy of Sciences, main machine is produced by China Academy of Sciences. It have abundant experience in Turbine theory's design and make, its product adopt patent construction combined moving pressure and static pressure, so its ability to resist the turbine's vortex is very strong, carrying capacity is big. It wines the advancement second and third Prize of Science and Technology by Academic of Sciences in 1995 and 1999. It have following advantages: Easy to
installation, convenient to maintain, running stable, high efficiency, small cooling losing.
5). Rectification Column
It adopt fin type heat exchange, made in aluminum, heighten heat exchange's affection, depress the operation pressure,reduce the power consumption furthest, saving cost. Temperature, flow and liquid display all adopt digital instrument.
