Abstract
A system for feeding and pumping of less pumpable material in a conduit line (28) is disclosed, comprising at least one main pump (10) for feeding of said less pumpable material into the conduit line (28), and a receiver unit (50) for receipt of the less pumpable material from the conduit line (28), wherein one or more independent driven compensators (40) are included in the conduit line (28) to maintain stable flow, said one or more compensators (40) being a fillable chamber (14;70) adapted to controllably being pressurized for additional feeding of the material through the conduit line.
Claims11
A system for feeding and pumping of less pumpable material in a conduit line, comprising:
- at least one pump for feeding of said less pumpable material into the conduit line, the at least one pump comprising two or more independently driven pump chambers;
- a receiver unit for receipt of the less pumpable material from the conduit line;
- and
- a control system, wherein during operation the control system is arranged to generate a function, based on position, velocity and pressure of the material in the conduit line, and to generate action signals (A1, A2, . . . An) to increase, reduce or maintain the flow rate, wherein the control system receives signals from the at least one pump and the receiver unit for determining said function, and said each of the two or more independently driven pump chambers comprises an inlet opening for input of the material into the two or more independently driven pump chambers, an outlet aperture for outlet of the material into the conduit line, and a valve arranged to controllably close or open the outlet aperture based on the action signals from the control system.
