Hydraulic Actuators (A9505)

In Mechanical Hydraulics

Details

This comprehensive interactive multimedia-training program consists of five individual lessons that train participants to identify system components, read schematics, and understand the conditions necessary for proper operation of a hydraulic system.

Prerequisites

This lesson is designed for participants who are familiar with the basic operating principles of hydraulic systems, hydraulic schematics, flow and pressure controls, and basic hydraulic safety considerations. An understanding of hydraulic pumps, pressure controls, and directional and flow controls is also necessary.

Description

This lesson discusses the designs, operating principles, and maintenance of hydraulic cylinders and hydraulic motors. The lesson shows and explains pressure and flow requirements for hydraulic cylinders and hydraulic motor performance. Test procedures for checking internal leakage in a cylinder are also demonstrated.

Objectives

Calculate electrical horsepower and piston speed. Describe the operation of single-acting, double- acting, and non-differential cylinders as well as the operation of cylinders controlled by regulating flow or pressure. Identify schematic symbols. Describe the operation of unidirectional and bi-directional motors, hydraulic pumps, hydraulic gear motors, hydraulic piston motors, hydrostatic drive circuits, braking circuits, and meter-in circuits.
