The impact of the shutdown seal air pressure on the expander.
Thread Content
The pressure of the sealing gas during normal operation is 1 MPa; when the machine is shut down, the pressure at the inlet of the sealing gas is 0.3 MPa. However, the pressure difference for both shutdown and operation is 150 kPa, which meets the requirements for starting the oil pump. The oil pressure is 0.9 MPa. Will a low seal air pressure during shutdown cause any problems?
No, the pressure is high during operation, and a pressure regulator is used to reduce it to normal levels.
