once again we will take look on bleed system of A320 with CFM-56-5B engine and exactly on IP check valve or Intermediate pressure valve.
The bleed systems of engines 1 and 2 are similar and operate independently of each other.
-
Air is tapped either from intermediate HP compressor stage through an IP bleed check valve or from high HP compressor stage through an HP bleed valve according to engine speed.
-
When engine speed is low, especially during aircraft descent with engine at iddle, IP port pressure is insufficient. The air is automatically bled from the HP port (high pressure, on the 9th stage) through the HP Bleed Valve and IP Bleed Check Valve is closed to prevent air recirculation.
-
When engine speed is high, the engine air bleed is in normal configuration. The air is bled from the IP port (intermediate pressure, on the 5th stage) through the IP Bleed Check Valve and HP Bleed Valve closes.
