Abstract

See full text

A method for determining a current wear (w) of a hydrostatic pump, particularly of a radial piston pump, with a variable-speed drive, where the pump is connected to a fluid passage, in which a fluid is pumped by the pump to create a current actual volume flow in the fluid passage. A current actual volume flow (Qact) is determined, by measuring the volume flow in the fluid passage at a predetermined drive-vector, a computed volume flow (Qcomp) is determined, by a first computational method, at the predetermined drive-vector, and the current wear (w) of the pump is determined, by a second computational method, which relates the current actual volume flow (Qact) to the computed volume flow (Qcomp).
