MODULE DETAILS

 

Hydraulics DMEHYD609

 

Nominal duration: 48 hours total time commitment

This time commitment includes the structured activities, preparation reading, and attendance at each webinar, completing exercises, practical assessments and proctored assessments.

 

It is also expected that students spend additional time on readings, personal study, independent research and learning, practicing on remote labs and required software and working on any projects and assignments.

 

This module covers the basic theory of pressure and flow, hydraulic cylinder classification and construction, control valve and pressure control valve classification and actuation, and types of electro-hydraulic systems.

MODULE PURPOSE

The purpose of the module is for participants to gain knowledge of the fundamentals of hydraulics, to improve their maintenance programs, and become effective trouble-shooters of problems in this area.

MODIFICATION HISTORY

Original module approved in 2010 (52243); 2013 (52606WA); 2016 (52810WA).  This version: V4.0

ASSESSMENT STRATEGY

 

METHODS OF ASSESSMENT

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, structured assessments, samples and questioning. This will include short answer questions on the knowledge content, the use of remote and virtual labs, and writing tasks to apply the learning to academic tasks.

 

CONDITIONS OF ASSESSMENT

 

Questioning techniques should not require language, literacy and numeracy skills beyond those required in this module. The candidate must have access to all tools, equipment, materials and documentation required.

 

The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

 

Assessments will be open book assessment and may be completed off-campus. Invigilation software will be used for some assessments to ensure authenticity of work completed.

 

Model answers must be provided for all knowledge-based assessments to ensure reliability of assessment judgements when marking is undertaken by different assessors.
