Equipment Operations in Hydraulic and Pneumatic Power Systems (Strand 4, Outcome 4.2)

Original Equipment Manufacturer (OEM)

The company that manufactures the equipment and provides specific instructions for its use.

Operator’s Manual

The authoritative source that outlines how a specific machine should be operated and what limits it must follow.

OEM Recommended Operating Procedures

Step-by-step methods specified by the manufacturer for safely operating machinery.

Adjustment Specifications

Approved settings and ranges for components such as relief valves and flow controls.

Relief Valve Settings

The maximum system pressure limit defined for safety in hydraulic systems.

Regulator Setpoints

Predefined downstream pressure levels in pneumatic systems.

Flow Control Settings

Parameters that determine speed control limits of hydraulic or pneumatic systems.

Torque Values

Specified amounts of force needed to tighten bolts and fasteners according to OEM guidelines.

Maintenance Instructions

Procedures related to the upkeep and service of the machine.

Troubleshooting Flowcharts

Guides to diagnose problems within the system based on symptoms.

Cavitation

Phenomenon that can occur in hydraulic systems due to insufficient fluid flow, leading to damage.

Duty Cycle

The ratio of time a machine can operate under load versus the time it needs to rest.

Electro-Hydraulic Controls

Control systems where electrical signals manage hydraulic actions.

Hydraulic System Pressure Gauge

An instrument used to measure the pressure within a hydraulic system.

Filter Restriction Indicators

Devices that alert operators when filters are clogged and require service.

Emergency Stop (E-Stop)

A safety control that immediately halts machine operation in emergencies.

Stored Energy

Energy stored in hydraulic fluid or compressed air that can pose hazards if not managed.

Lockout/Tagout (LOTO)

Procedures to ensure machinery is properly shut down and not able to be started up again before maintenance is completed.

Quick-Coupler

A fast connection device for hydraulic hoses that allows for quick attachment/detachment.

Air Receiver

A storage container for compressed air that helps maintain pressure in pneumatic systems.

Lubrication Intervals

Scheduled times or mileage criteria for adding oil or lubricant to machinery.

Moisture Management

Controlling water in pneumatic systems to avoid corrosion and operational issues.

Case Drain Requirements

Specifications for returning excess hydraulic fluid from motors to prevent over-pressurization.

Pressure Limits

The maximum allowable pressure for components, defined by OEM specifications.

Functional Checks

Performance evaluations of a machine to ensure proper operation prior to use.

Common errors during inspection

Mistakes made during inspections such as not checking hydraulic leaks correctly.

Gradual Start-up Procedure

A method of safely bringing a machine from idle to operational states.
