Examine a range of load control circuits to understand some of the problems and pitfalls of moving loads with hydraulics. We consider each circuit and discuss the pressure balances that make them work. We show you how to experiment with our valve simulations to explore the circuits and better understand how they work.
Please note that the fluid stiffness values have been reduced in our simulation to better demonstrate the potential problems when using different load control circuits. This can be seen in delays when lifting the cylinder and oscillations when it's stopped suddenly. The issues do appear in actual systems but are only a problem apart for highly dynamic or high accuracy control systems. Examples include:
