portion of existing GI piping structure inside the plant. Ultimately energy used for compressed
air generation goes in waste. Preventive maintenance of automatic condensate drain traps is
necessary to avoid stuck up of plunger in the trap and helps in easy draining of condensate
accumulated in the compressed air receiver itself.
From above photograph, it clear that Pop up time sets for 10 sec and interval time set at 20
minutes. This setting leads to more drainage of compressed air. Hence its recommended to set
pop up time as 4 sec and interval time as 30 minutes for minimum drainage of compressed air
through receiver.
Observed pressure gauges and pressure relief valve mounted on receiver. Care should be taken
to calibrate both at frequency of yearly from the safety point of view of human and company
property.
