FLOW REGULATOR AS WELL AS METHOD FOR SETTING A PREDEFINABLE VOLUME FLOW |
摘要 |
A flow regulator includes a first sensor determining a first actual value of a first flow parameter of the fluid, a pre-pressure regulator setting a predefinable pre-pressure at a pre-pressure outlet of the pre-pressure regulator, and a regulating pump. The fluid is capable of being supplied to the pre-pressure regulator at a plant pressure in an operating state via an inflow line and a pre-pressure inlet and capable of being conducted further to the regulating pump at the pre-pressure via a flow connection disposed between the pre-pressure outlet and the regulating pump, the pre-pressure outlet being connected to a high pressure connection of the regulating pump in a flow communicating manner via the flow connection such that the fluid is capable of being supplied from the pre-pressure regulator of the regulating pump and guided away from the regulating pump via a low pressure connection into an outflow line. |

1. A flow regulator for setting a predefinable volume flow of a fluid, comprising:
a first sensor configured to determine a first actual value of a first flow parameter of the fluid; a pre-pressure regulator configured to set a predefinable pre-pressure at a pre-pressure outlet of the pre-pressure regulator; and a regulating pump in the form of a rotary pump, the fluid capable of being supplied to the pre-pressure regulator at a plant pressure in an operating state via an inflow line and a pre-pressure inlet and capable of being conducted further to the regulating pump at the pre-pressure via a flow connection disposed between the pre-pressure outlet and the regulating pump, the pre-pressure outlet being connected to a high pressure connection of the regulating pump in a flow communicating manner via the flow connection such that the fluid is capable of being supplied from the pre-pressure regulator of the regulating pump and guided away from the regulating pump via a low pressure connection into an outflow line, a speed of rotation of the regulating pump capable of being set by a regulating control using a first desired value in dependence on the first actual value of the first flow parameter such that a limiting pressure acting against the pre-pressure is capable of being produced by the regulating pump so that the predefinable volume flow of the fluid is set in the outflow line. |
