Original Abstract

The vibrations of hydraulic pump and connected pipeline system are very problematic and often hardly soluble. The high pressure pulsations of hydraulic pump with the double suction inlet are investigated. For that reason the static pressure and accelerations are measured. The numerical simulations are carried out in order to correlate computed data with experimental ones and assess the main source of vibrations. Consequently the design optimization of the inner hydraulic part of pump is done for further experimental measurements with the variable pump discharge and speed. Several optimizations were considered – guide ribs in pump suction, an optimized diffuser and modified shaft bearings. The influence of optimized designs on the pump vibrations is discussed.
