Quality control of liquid air separation plant maintenance and installation

Liquid air separation plant piston compressor clearance volume is: the compressor at the end of the exhaust, the piston and the cylinder end of the wall between the residual part of the high pressure gas occupied by the cylinder volume. The existence of the residual volume directly reduces the exhaust volume of the compressor, at the same time, the suction of this part of the high pressure gas expansion, will also cause a delay in the suction process, the reduction in suction volume, ultimately ...

The load adjustment range of low pressure small air separation unit is related to the adjustment performance of the raw material compressor, the adjustment performance of the expander, the structural characteristics of the distillation tower and other factors. At present there are imported guide vane of the turbine air compressor flow adjustment range in 75-100%; adjustable nozzle of the turbine expander adjustment range can be in 65-100%. When oxygen is rich and the need to reduce oxygen produc...
