Abstract
A method for supplying compressed gas via an assembly (1) having a plurality of liquid-injected elements (6, 8) for compressing gas, wherein the method includes providing a first liquid connection between a first liquid circuit related to a first of the plurality of liquid-injected elements (6) and the second liquid circuit related to a second of the plurality of liquid-injected elements (8).
Claims21
An assembly (1) for compressing a gas, the assembly including at least:
- a first liquid-injected element (6) for compressing gas;
- a first motor (7) for driving the first element (6);
- a second liquid-injected element (8) for compressing gas;
- a second motor (9) for driving the second element (8);
- a first liquid circuit related to the first liquid-injected element (6), which first liquid circuit includes:
- a first liquid supply line (21) for supplying liquid to a liquid inlet (22) of the first liquid-injected element (6);
- a first liquid separator (10) in fluid connection via a first fluid line (11) with a gas outlet of the first liquid-injected element (6), whereby a first non-return valve is provided downstream of a gas outlet of the first liquid separator (10);
- a first liquid cooler (14) in fluid connection between a liquid outlet (15) of the first liquid separator (10) and the first liquid supply line (21);
- a second liquid circuit for the second liquid-injected element (8), which second liquid circuit includes:
- a second liquid supply line (23) for supplying liquid to a liquid inlet (24) of the second liquid-injected element (8);
- a second liquid separator (12) in fluid connection via a second fluid line (13) with a gas outlet of the second liquid-injected element (8), whereby a second non-return valve is provided downstream of a gas outlet of the second liquid separator (12);
- a second liquid cooler (16) in fluid connection between a liquid outlet (17) of the second liquid separator (12) and the second liquid supply line (23);
- wherein a fluid connection is provided between the first liquid circuit and the second liquid circuit.
A method for supplying compressed gas via an assembly (1) having a plurality of liquid-injected elements (6, 8) for compressing gas, wherein the method includes:
- providing a fluid connection between a first liquid circuit related to the first of the plurality of liquid-injected elements (6) and a second liquid circuit related to a second of the plurality of liquid-injected elements (8).
- whereby the first liquid circuit includes:
- a first liquid supply line (21) for supplying liquid to a liquid inlet (22) of the first liquid-injected element (6);
- a first liquid separator (10) in fluid connection via a first fluid line (11) with a gas outlet of the first liquid-injected element (6), whereby a first non-return valve is provided downstream of a gas outlet of the first liquid separator (10);
- a first liquid cooler (14) in fluid connection between a liquid outlet (15) of the first liquid separator (10) and the first liquid supply line (21),
- and whereby the second liquid circuit includes:
- a second liquid supply line (23) for supplying liquid to a liquid inlet (24) of the second liquid-injected element (8);
- a second liquid separator (12) in fluid connection via a second fluid line (13) with a gas outlet of the second liquid-injected element (8), whereby a second non-return valve is provided downstream of a gas outlet of the second liquid separator (12);
- a second liquid cooler (16) in fluid connection between a liquid outlet (17) of the second liquid separator (12) and the second liquid supply line (23).
