Answer Posted / engineer muhammad masoom shafi
Surging is a momentary back flow through the compressor from
the discharge to the suction.This can occur when the mass
flow of gas to the compressor falls below a critical level
with a high pressure difference across the m/c.when there is
not enough gas to replace that being pushed
Forward,discharge gas will flow backwards through the
compressor towards the suction side this back flow will tend
to decrease the speed of rotation while the speed controller
will try to maintain the correct speed.the gas flowing
backward provides more volume to the suction side and the
compressor picks up and begins to push gas forward again.the
m/c speed will tend to increase and the governor will again
try to maintain the correct,set speed.all of this take place
very quickly,the forward and backward gas flow together with
the speed control action cause rapid fluctuation in the flow
and pressure in the system.this surging condition is similar
to an aircraft'stall'condition,or pump cavitation.
