METHODS AND ADJUSTING CIRCUITS FOR SPEEDS AND RPM FOR HYDRAULIC MOTORS

Ionuţ Adrian CHIS, Ştefan Ionuţ CRACIUN, Anca SARB

Abstract


The use of a larger scale for hydraulic actuating for industries which complain the equipment with high density of high forces, required developing of adjusting and control methods of these systems. Adjusting the displacement speed of a linear hydraulic motor, respective for RPM developed by a hydraulic rotary motor is realized by applying the volume method or resistive method. A special case is represented by closed hydraulic circuits where id used primary, secondary or mixt adjustment for variation of a hydraulic rotary motor RPM.

Key words: linear speed, rpm, adjusting circuit, volume method, resistive method
