Abstract
In order to degas a device (7), an apparatus (10) is provided that comprises a control unit (19), a pump (3), a first volume (1,2), a second volume (6), valve means (12), a first valve (15) and a second valve (14). At the discharge end, the pump (3) is connected to an air outlet (21) via the valve means (12) and to the first volume (1, 2) via the valve means (12). The first volume (1, 2) and the second volume (6) are connected via the first valve (15). At the intake end, the pump (3) is connected to the first volume (1, 2) via the second valve (14) and can be connected to the device (7) to be degassed.
Claims17
An apparatus comprising a degassing vessel which is configured to be filled with a liquid to be degassed, the apparatus further comprising:
- a pump, which is configured to pump gas and which, at a discharge end, is connected to an air outlet via a valve device and to a first volume via the valve device,
- wherein the first volume and a second volume are connected via a first valve,
- wherein, at an intake end, the pump is connected to the first volume via a second valve and is configured to be connected to the degassing vessel to be degassed, and
- a control unit for activating the pump, the valve device, the first valve and the second valve,
- wherein the control unit is configured to switch the valve device such that the valve device connects the pump only to the air outlet at the discharge end, to open the first valve and the second valve, and to then evacuate the degassing vessel, the first volume and the second volume by means of the pump.
A test system comprising:
- an evaluation unit and an apparatus comprising a degassing vessel which is configured to be filled with a liquid to be degassed,
- wherein the apparatus further comprises:
- a pump, which is configured to pump gas and which, at a discharge end, is connected to an air outlet via a valve device and to a first volume via the valve device,
- wherein the first volume and a second volume are connected via a first valve,
- wherein, at an intake end, the pump is connected to the first volume via a second valve and is configured to be connected to the degassing vessel to be degassed, and
- a control unit for activating the pump, the valve device, the first valve and the second valve,
- wherein the control unit is configured to switch the valve device such that the valve device connects the pump only to the air outlet at the discharge end, to open the first valve and the second valve and to then evacuate the degassing vessel, the first volume and the second volume by means of the pump, and
- wherein the evaluation unit and the apparatus are configured to carry out an analysis of the gas in or from the degassing vessel.
