Explanatory notes 1 This unit standard is intended for, but not restricted to, workplace assessment. The range statements within the unit standard can be applied according to industry specific equipment, procedures and processes. 2 Safety of personnel and plant must be a priority throughout the assessment. If the safety requirements are not met the assessment must stop. 3 Performance and work practices in relation to the outcomes and evidence requirements must comply with all current legislation, especially the Electricity Act 1992, and any regulations and codes of practice recognised under that statute; the Health and Safety in Employment Act 1992; and the Resource Management Act 1991. Electricity supply industry codes of practice and documented industry procedures include the current version of the Safety Manual – Electricity Industry (SM-EI) Wellington: Electricity Engineers’ Association. A full list of current legislation and industry codes is available from the Electricity Supply Industry Training Organisation, PO Box 1245, Hamilton 3240. 4 The phrase in accordance with industry requirements is implicit in all outcomes and evidence requirements in this unit standard. Electricity Supply Industry Training Organisation SSB Code 101813 New Zealand Qualifications Authority 2016 NZQA registered unit standard 10413 version 5 Page 2 of 5 5 Industry requirements include all asset owner requirements; manufacturers’ specifications; and enterprise requirements which cover the documented workplace policies, procedures, specifications, business, and quality management requirements relevant to the workplace in which assessment is carried out. 6 This unit standard excludes pipework and isolation valves. 7 The term service includes preventative maintenance, inspections, cleaning, and monitoring. Outcomes and evidence requirements Outcome 1 Demonstrate knowledge of the principles of pump operation and construction in electricity supply power plants. Range includes – rotating screw and rotating centrifugal, reciprocating diaphragm, reciprocating piston (radial and axial), rotating gear, rotating multi-stage, rotating axial, rotating vane. Evidence requirements 1.1 The principles of pump operation are described. 1.2 Pump construction and components are described. Outcome 2 Plan service requirements for pumps and components in electricity supply power plants. Range maintenance records, scope of work, resources, drawings. Evidence requirements 2.1 Work plans are prepared. 2.2 Prepared plans identify all necessary procedures and resources required for the service. 2.3 Work plans and specifications are complete, concise, and legible, and reflect identified hazards. Identified hazards are eliminated, isolated, or minimised. 2.4 Work plans and specifications are made available for all personnel involved in implementing the plans within the scheduled time-frame. Electricity Supply Industry Training Organisation SSB Code 101813 New Zealand Qualifications Authority 2016 NZQA registered unit standard 10413 version 5 Page 3 of 5 Outcome 3 Service pumps and components in electricity supply power plants. Range pumps include rotating screw and rotating centrifugal, and at least two from – reciprocating diaphragm, reciprocating piston (radial and axial), rotating gear, rotating gerotor, rotating multi-stage, rotating axial, rotating vane. Evidence requirements 3.1 Isolations are checked. 3.2 Pumps and components requiring service are identified. 3.3 Pumps and components are serviced. Range 3.4 includes but is not limited to – check pump is functioning within flow, temperature, pressure, vibration, and noise specifications; visual inspection for damage and leaks, flanges, glands, fittings, adjust glands, adjust bearing lube oil flows, adjust cooling and gland seal flows, check condition of coupling for wear, tightness, lubrication, check mountings for security and tightness fasteners, pins, change or clean filters, check indications, alarms, protection, drive guards, labelling. Service activities and resources are co-ordinated throughout the duration of the work to minimise disruption to personnel, plant, electricity generation, and the environment. Outcome 4 Test pumps and components in electricity supply power plants. Range test run, alignment, on load, off load, test readings, calibrations, check performance within specification flow, pressure, temperature, vibration, noise, cavitation, priming, lubrication, gland leakage, check auto cut-in, alarm operation, indications. Evidence requirements 4.1 Tests are carried out in accordance with the prepared work plan. Electricity Supply Industry Training Organisation SSB Code 101813 New Zealand Qualifications Authority 2016 NZQA registered unit standard 10413 version 5 Page 4 of 5 Outcome 5 Report a routine service. Range service report, job sheet, daily diary, log book, test reports and results, plant history, authorisations. Evidence requirements 5.1 Reported information is completed and actioned. 5.2 Maintenance information is recorded in the agreed format and filed within scheduled time-frame. 5.3 Any further action required for plant and equipment is identified, recorded, and communicated to appropriate personnel.
