Customer Requirements

• Reducing the testing time for manual testing from 25 minutes to 5 minutes
• Communication with SAP-server for test data interrogation and test result storage
• Calculation program regarding temperature and viscosity of the media
• User interface in accordance with customer specifications
• Fully automatic sequencing with system verification and security check
• The operator can prepare other pumps in parallel

Implemented Solution

• The test stand was developed to determine industrial pump specifications, including characteristic and flow rate and to record the suction and pump pressure and to compare them to the client's requirements.
• The test data is downloaded automatically from SAP by entering the tracking ID of the DUT. The test data is also stored in SAP.
• The test system takes over the activation and regulation of the pump motor at different speed settings. A slider for regulating the pressure is also controlled by the test system.
• Various range of sensors for parameters like pressure, flow rate and temperature are also a part of the system.
• The test is fully automated, as soon as the pump is mounted into the system. Should any of the values fall outside the determined tolerance values, the system immediately interrupts operation and displays an error message.
• The temperature measurement is of prime importance, as it is used as a basis to calculate the environment's viscosity and to derive other calculation offsets. If necessary, a cooling unit will also be activated in the medium tank.
• The ordered system was designed as a real-time embedded system, to guarantee the necessary operation security. For this reason, we used a CompactRIO system from National Instruments, equipped with the corresponding signal conditioning modules for sensor integration.
• All data is stored and managed online in SAP, so that the customer may automatically receive the characteristic lines corresponding to one particular pump.
