Problems with air compressor startup and pressure increase
Thread Content
Different air compressor models have different pressures; how should the pressure increase rate be controlled during startup? And what about the anti-surge curve? How is it created? Thank you.
In my opinion, when raising the pressure with an air compressor, there’s no need to strictly control it based on speed; just close one exhaust valve. As the pressure starts to rise, if its increase slows down, then close another valve – this approach is actually quite effective. It takes about an hour to raise the air compressor to 0.53 MPa. Additionally, the anti-surge curve is a rough curve prepared by the manufacturer at the time of compressor delivery. After the unit is installed and commissioned, the manufacturer conducts anti-surge performance tests under supervision in the workshop, with the aim of identifying the unit’s three anti-surge points in order to draw a curve, which is the anti-surge curve diagram. For details, you can refer to http://bbs.hcbbs.com/thread-893641-1-1.html; it explains everything clearly there.
