NIMS Industrial Technology Maintenance - Basic Hydraulic SystemsRequest Info
Duty Area 3: Basic Hydraulic Systems
This duty area covers: adhering to fluid power systems safety rules; interpreting basic fluid power schematics; starting up and shutting down a hydraulic system and adjusting system pressure; adjusting hydraulic actuator speed using a flow control valve; servicing hydraulic fluid and a hydraulic filter; installing hydraulic conductors and installing and testing components in a basic hydraulic circuit; and troubleshooting a basic hydraulic circuit.
Hydraulic Systems 1 (50131)
This course covers hydraulic pumps, circuits, pressure and flow concepts and control, and sequence control. Examples of topics include: how to read a pressure gauge; the operation of a hydraulic power unit; the function of a 3-position, 4-way directional control valve; calculating the force output of a hydraulic cylinder in retraction; the advantages of a pilot-operated relief valve; the effect of actuator load changes on flow control valve operation; and the operation of a direct-acting sequence valve.
Hydraulic Systems 2 (M50132)
This course covers hydraulic directional control valve applications, hydraulic cylinder applications, hydraulic relief valve applications, hydraulic pilot-operated check valves, and hydraulic accumulators. Examples of topics include the operation of a hydraulic 4/2 cam-operated valve, how to calculate the extend speed of a cylinder in regeneration, the operation of a remote-controlled relief valve circuit, the function of a prefill valve, and how to pre-charge a gas-loaded accumulator.
Hydraulics Troubleshooting 1 (M50133)
This course covers troubleshooting hydraulic pumps, actuators, valves on a component level and overall hydraulic systems. Examples of topics include methods of testing a hydraulic component, causes of pseudo-cavitation, how to adjust a cylinder cushion, inspecting and troubleshooting a check valve, symptoms of relief valve failure, and the construction of a troubleshooting flowchart.
Hydraulics Maintenance 1 (M50134)
This course covers the maintenance of hydraulic filters and fluids and the replacement of fittings, seals, hydraulic hoses, steel tubing, and other hydraulic components. Examples of topics include the ISO 4406 contamination code, the proper fluid to use in a hydraulic system based on manufacturer’s documentation, the operation of a straight thread O-ring fitting, installing a hydraulic hose using brackets and clips, the function of thread sealant in a hydraulic system, and how to replace a subplate-mounted valve in a hydraulic system.
Industrial Safety (M50101)
This course covers safety organization, personal protective equipment, HAZCOM, confined spaces, electrical safety, fire safety, accident response, workplace ergonomics, and maintenance organization. Examples of topics include creating a culture of safety in the workplace, using head, eye, and ear protection personal protective equipment, explaining the importance of chemical container labeling, providing characteristics of a permit-required confined space, the function of an electrical lockout/tagout system, using a fire extinguisher, preventing bloodborne pathogen exposure, interpreting common safety markings, and visual management tools used in the workplace.
