The Application of Inlet Pressure Self-adjustment System in Changchun——Jilin Oil Pipeline

The inlet pressure self-adjustment system installed in Changchun——Jilin oil pipeline works based on the- pump station control system to trace and adjust the operating pressure.which makes the inlet pressure not less than 0.5 MPa (the designed minimum pressure). If inlet pressure is beyond the designed maximum pressure (1.6 MPa), the system will close the valves automatically to provide a safe protection. The inlet pressure realizes self-adjustment through the throttling of regulating valve. Relying on this pressure self-adjustruent system, some equipments like oil-feed pump and flowmeters can safely operate.
