Hydraulic Motor & Constant Torque

[QUOTE="HydraulicsLearner, post: 5447656, member: 591361"] Hi, I'm a beginner on hydraulics and have been reading up a lot of literature. But I'm not sure if my assumptions are accurate and I hope I can discuss with other forumers here! My apologies in advance if my questions seem silly! Background: My goal is to drive a hydraulic motor at constant pressure & constant RPM so that I can achieve constant output torque. 1. Hydraulic pump is a positive displacement pump. (the RPM is variable) 2. I would like the hydraulic motor to produce constant output torque. Is it correct to assume [B]constant pressure & fixed RPM = constant output torque[/B]. Would a hydraulic accumulator be able to perform this function - give out constant pressure & fixed output/discharge flow (which would fix the RPM at a specific motor displacement) using a flow controller? 3. How do I design the circuit to make sure all fluid from the pump goes into the accumulator first, before passing into the hydraulic motor? Are there hydraulic accumulators with 2 separate ports (charge & discharge)? Can charge & discharge happen simultaneously at different rates?I'm learning to use Automation Studio to simulate the circuit (please let me know if you can recommend better software for beginners!) Many thanks! HydraulicsLearner [/QUOTE]
