Select and manage pumping systems for irrigation

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Elements and Performance Criteria

Element

Performance criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Identify irrigation system requirements from the irrigation design

1.1 Identify the components of an irrigation pumping system

1.2 Determine the water source and height of pull for water into the system

1.3 Determine the water output for irrigation

1.4 Calculate the total friction loss of irrigation components

2. Select pump according to type, installation, range of flow rates, operating head and delivery distance

2.1 Select the basic type of pump based on the pump task and placement and the power source

2.2 Calculate the total operating head required

2.3 Calculate the required discharge for the pump based on the irrigation output required and friction losses in the system

2.4 Determine the speed and power requirements of the pump motor

2.5 Determine the limiting suction lift of the pump

2.6 Interpret pump performance curves when selecting an efficient irrigation pump

2.7 Determine the size of the impeller from the pump curve

3. Supervise installation of pumps

3.1 Ensure pump is sited as close as possible to water source and is level

3.2 Verify pump is properly anchored and connections are airtight

3.3 Confirm pump and motor connection are correctly aligned and motor is ventilated

3.4 Verify filters and valves are correctly fitted and orientated

3.5 Check pump is connected to the irrigation controller if required

4. Oversee commissioning and testing of pumping system

4.1 Develop pre-start and start up procedures

4.2 Check delivery performance and verify power usage and water output against requirements and pump specifications

4.3 Ensure pumping system is checked for leakages and cavitation

4.4 Determine that pumping system is operating effectively

5. Develop maintenance procedures for the pumping system

5.1 Develop routine maintenance procedures to rectify the effects of normal wear

5.2 Develop periodic inspection checklists to assist in maintenance scheduling

5.3 Carry out pump overhaul or repairs

5.4 Keep pump maintenance records, including details of the pump and all pumping system components for ordering

6. Carry out troubleshooting on pumping systems

6.1 Investigate lack of discharge or pressure and change settings or components

6.2 Investigate loss of water suction and make alterations to placement or fix leakages

6.3 Investigate cavitation in pumps and change settings or components

6.4 Investigate excessive power consumption and review design and pump selection and check for mechanical defects
