This lecture explains the features of the classification of the pumps which is internationally recognised and thus it ensures that the designation once used conveys the same information without ambiguity.
A few basic concepts related to pumps and hydraulics are explained in this lecture before going further.
In this lecture we will cover the phenomenon of cavitation and its relationship with Net Positive Suction Head available. We will further introduce the re-circulation and vortex formation.
Pump performance curves are loaded with information and some times not so clear as different manufacturers use different formats. We explain these subtleties in detail.
A good quality control plan agreed between the supplier and end-user can lock the manufacturing processes required to ensure the reliability of the products.
How to reduce the measurement uncertainty in order to achieve a narrow tolerance band?
The tolerance band selection is an important decision. Narrow tolerance band means higher costs and longer delivery periods. Wider tolerance band means higher fluctuations in the expected performance, besides higher safety margin in the prime mover rating.
Find out which type of testing arrangement is necessary for critical application pumps.
Every measurement instrument even though properly calibrated has a certain measurement uncertainty. Check the instrument details according to the requirements of the acceptance grade.
The students will be able to direct an inspection or a shop test.
The procedure and paraphernalia for measuring pump efficiency will be clear to the participants for use.
NPSH testing needs hands on experience depending on different cases. Through this lecture they will be able to manage the NPSH testing on the test bed.
Interpretation of the vibration results will be possible since the criteria for different situations and standards is clearly explained in this module.
Concluding the inspection and acceptance testing is a challenging task especially if the test results are on the borderline. After attending this lecture the criteria for decision making will be clear.
This course is designed for engineers and managers striving to ensure high reliability whenever preparing specifications, purchasing, inspecting or conducting acceptance testing of critical application pumps and pumping systems. This course covers:
1. The quality assurance processes (using QCP) essential for manufacturing of a quality product,
2. The QCP includes the details of hold points and witness points necessary for ensuring the right quality of the product.
3. The QCP includes types of certifications and procedures for the materials supplied by the vendors and traded goods suppliers.
4. Steps in the form of templates necessary for conducting an effective inspection,
5. Acceptance testing according to standards, ISO 9906 and HI 14.6 are included in this course and the acceptance and rejection criteria is clearly discussed and explained/
6. Interpretation of acceptance test results and further actions.
These processes are explained in detail, along with requirements and applications elaborated with examples. Worked examples, templates, graphs and exercises are used to facilitate application in the field. Additional literature and contemporary pump industry practices are discussed extensively to enrich the content and to enhance its practical value. The course is divided into modules each of suitable duration to allow participants to plan attendance according to their convenience.
