| abstract |
The invention relates to a test stand for pressurized safety devices (S1, S2, S3), which are acted upon by a test pressure by liquid pressure medium, wherein the liquid pressure medium from a container is provided and the pressure of the liquid pressure medium with a pump (33) and generated by means of a pressure gauge is readable / detectable. According to the invention, the pump (33) is connected to the water tank (28) via a first pressure medium line (34), wherein a second pressure medium line (37) leads from the first pressure medium line (34) to a three-way ball valve (43) and a high-pressure hose (45) the three-way ball valve (43) is connected. Furthermore, from the three-way ball valve (43) to the water tank (28), a third pressure medium line (51), wherein the high-pressure hose (45) connected to the safety device to be tested and by detection - the pressure drop of the test pressure with the pressure gauge and / or - A change in the water tank (28) located amount of pressure medium or - The exit of pressure medium from the safety device is testable. |
