Characteristics of centrifugal compressor wheezing phenomenon in small air separation unit

Author: DEAR AST

Centrifugal compressor operation once the phenomenon of wheezing, the unit and the operation of the pipe network has the following characteristics.

(1) the gas medium outlet pressure and inlet flow rate changes significantly, sometimes may also produce gas backflow phenomenon. The gas medium is discharged from the compressor to the inlet, which is a dangerous working condition.

(2) Periodic vibrations in the pipe network, with high amplitude and low frequency, accompanied by a periodic "roar" sound.

(3) The compressor body vibrates strongly, the casing, bearings have strong vibration, and a strong periodic airflow sound, due to strong vibration, bearing lubrication conditions will be damaged, shaft tile will burn, or even shaft is twisted off, the rotor and stator will produce friction, collision, sealing components will be seriously damaged.

Once the compressor enters the wheezing condition, the operator should immediately take adjustment measures to reduce the outlet pressure, so that the compressor in small air separation unit quickly out of the wheezing zone, to achieve stable operation of the compressor.

Due to improper adjustment of seal gas pressure during operation, liquid oxygen pump can not pump liquid or leak.   From the quality point of view, when the sealing pressure is too high, there will be gas leakage into the pump through the labyrinth seal, resulting in the impeller with gas or even idling, resulting in liquid injection or pressure drop; when the air pressure before sealing is too low, there will be liquid oxygen leakage.   From the quantity point of view, when (p1-p3...
