Learners using Amatrol’s intermediate hydraulics eLearning course will study various aspects and components of accumulators, including accumulator operation, applications, circuits, and sizing. Individual lessons focus on topics like the operation of the four types of gas-loaded accumulators, the function and operation of two types of safety bleed-down circuits, and the operation of a circuit that uses an accumulator for fluid dispensing. Learners will also practice skills, such as connecting and operating an accumulator bleed-down circuit, connecting and operating an accumulator to safely provide auxiliary and/or emergency power, and designing an accumulator circuit to compensate for leakage.
