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

1 Identify irrigation system requirements from the irrigation design

1.1 The components for an irrigation pumping system are identified

1.2 The water source and height of pull for water into the system are determined

1.3 The water output for irrigation is determined

1.4 The total friction loss of irrigation components is calculated

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

2.1 The basic type of pump is selected based on the pump task and placement and the power source

2.2 The total operating head required is calculated

2.3 The required discharge for the pump is calculated based on the irrigation output required and friction losses in the system

2.4 The speed and power requirements of the pump motor are determined

2.5 The limiting suction lift of the pump is determined

2.6 Pump performance curves are interpreted in selecting an efficient irrigation pump

2.7 Size of impeller is determined from the pump curve

3 Install pumps

3.1 Pump is sited as close as possible to water source and level

3.2 Suction and delivery pipes are attached correctly

3.3 Pump connections are airtight

3.4 The pump is anchored on a base

3.5 Pump and motor connection are correctly aligned

3.6 Ventilation is provided for the motor

3.7Filters and valves are fitted and valves are correctly oriented

3.8 Pump is connected to the irrigation controller if required

4 Commission and test irrigation pumps

4.1 Procedures are developed and implemented for carrying out pre-start checks

4.2 Pump start up procedures are developed and implemented

4.3 Pumps are pressure tested to check delivery performance

4.4 Power usage and water output is checked against requirements and pump specifications

4.5 Pumping system is checked for leakages and cavitation

4.6 Pump control systems are checked for accurate operation

5 Develop maintenance procedures for the pumping system

5.1 Routine maintenance procedures are developed to rectify the effects of normal wear

5.2 Periodic inspection checklists are developed to assist in maintenance scheduling

5.3 Pump overhaul or repairs are carried out

5.4 A pump maintenance record is kept, including details of the pump and all pumping system components for ordering

6 Carry out troubleshooting on pumping systems

6.1 Lack of discharge and/or pressure are investigated and settings or components changed

6.2 Loss of water suction is investigated and alteration made to placement or leakages fixed

6.3 Cavitation in pumps is investigated and settings or components changed

6.4 Excessive power consumption is investigated and design and pump selection reviewed and checks made for mechanical defects
