Vane pump test rig (Vickers pump V104C)
The method according to this standard is used to determine the wear protection behavior of hydraulic fluids in a vane pump (DIN 51 389 Parts 1 and 2).
The hydraulic fluid to be tested is circulated in a test rig by a vane pump at a specific temperature and pressure. The wear of the ring and vane of the pump is measured after the test run.

The temperature is selected so that the oil viscosity is 13 mm²/s. The 12 blades slide on the ring mainly in the area of mixed friction. The contact force results largely from the pressure of the hydraulic fluid. Since 2010, a newly developed hydraulic pump test rig has been in operation, specially adapted to the new standard test pumps from Conestoga (USA). In addition, the design and measurement technology were optimized. |
