Description

technical field

[0001] The invention belongs to the technical field of pipeline transportation control systems, in particular to a slurry pipeline transportation cascade control system, and also relates to a control method for the slurry pipeline transportation cascade control system. Background technique

[0002] Slurry pipeline transportation can be used as an important resource transportation method besides railway, highway and waterway transportation, and has a wide range of applications. In order to meet the delivery requirements, the flow rate and pressure are the key process parameters that need to be controlled during the delivery process. Traditional slurry pipeline transportation requires manual calculation of upstream process material flow to determine the delivery flow. It is also necessary to manually adjust the pump speed to balance the inlet pressure of the pump station.

[0003] Traditional long-distance slurry pipeline transportation adopts multi-stage pum...
