Universal test stand up to 1000 bar
The testing machine is designed for testing straight fittings for strength and tightness in accordance with DIN EN ISO 12266-1 in the dimension range from NS 15 to NS 150.
The required test pressure (water mass) for the strength test P10 and tightness of the load-bearing housing P11 is max. 1000 bar and is adapted accordingly for the low pressure levels (NP 16 to NP 160, CL 150 to CL 2500) stored in the test program. The water pressure is generated using two high-pressure pumps based on the principle of pneumatic-hydraulic pressure transmission. The water pressure is regulated by regulating the pneumatic pressure. To ensure P 12 seat tightness, a max. air pressure of 6 bar with corresponding adjustment to the lower nominal pressures is required. The pressure is taken directly from the compressed air network. The test water is transported from the water tank through a filter with pump into the filling tank. Subsequently, the test specimen, which is then under vacuum, is filled with the water. The vacuum ensures that there is no air in the test specimen. After filling, the test pressure is generated. The pressure drop during the test is measured by a pressure sensor and signalled accordingly.
The test parameters input is realised in a customer-specific manner from permanently programmed values via manually changeable ones up to the type-specific test database. The test results are also evaluated customer-specifically, from simple signalling of the test result via signing to a database of the test results with automatic certificate generation.
