Introduction
If the capabilities of the manufacturer's test facilities do not meet the material conditions necessary to test the pump under actual flow/head conditions, a model may be selected:
type pump instead: With the help of similarity theory, the model pump data is used to scale and evaluate the performance of the real pump to be manufactured: Choose to use the model
The principles for testing type pumps (or real type pumps) are as follows:
---Pump performance such as flow rate and/or pump input power (such as flow rate ≥35000m3/h, pump input power ≥5000kW) exceeds the test
the limits of testing facilities;
---A certain part or parts of the pump are concrete structures, and it is impractical to replicate them as a whole:
Taking into account the given practical conditions, the application of model pumps in hydraulic performance acceptance tests is a practical and efficient alternative: Use model
Advantages of type pumps may also include:
---Higher precision due to differences in measurement uncertainty;
---The lowest cost considering materials and other resources;
---Shorten the delivery time of real-type pumps:
Over the years, manufacturers have developed and presented independent approximate calculation methods and accumulated experience in applying similar pump theory and its details:
Relevant literature also introduces several computational models: This document describes the hydraulic performance acceptance test methods of model pumps, and GB/T 3216-
Other test methods specified in:2016 (Hydraulic Performance Acceptance Test for Real Pumps):
This document was originally written based on previous standards (such as JISB8327), and the final version is given in conjunction with GB/T 3216-2016
The latest pump hydraulic performance acceptance test method is formulated:
Hydraulic performance acceptance test of rotary power pump model pump
1 Scope
This document specifies the use of a small size pump (centrifugal pump, mixed flow pump and axial flow pump, hereafter referred to as the model pump) for hydraulic performance acceptance testing
Testing methods (including cavitation test)
This document is applicable to pump acceptance tests using geometrically similar model pumps to ensure that large-size pumps (below
Called real type pump) performance: However, this document does not prevent temporary overall inspection or other testing of full-type pumps: At the same time, I also think that it is best to carry out real type
Pump test unless subject to the following conditions:
---Pump capacity (pump flow and/or pump input power) exceeds the limits of the test facility, although it is difficult to establish based on flow or power
Criteria for substituting model pump tests for full-scale pump tests;
---A certain part of the pump is a concrete structure, and it is impractical to replicate it as a whole;
---Model testing specified by the buyer;
---For other reasons, it is difficult to conduct real-type pump tests:
This document is applicable to performance tests under stable operating conditions corresponding to real-type pumps:
