1. The Objective |
|
The objective of this document is to lay down a standard procedure for performance tests of horizontal centrifugal pumps at our test facility. |
| |
|
| |
2. The Conformance |
|
The tests to be carried out at the facility will conform, primarily, to the requirements laid down in ISO 9906 for Grade -1 testing. The most recent version of this standard will be the guiding conformance document for the test setup. The test set up has been prepared to conform also to ANSI/HI standards for testing of horizontal and vertical centrifugal pumps. |
| |
|
| |
3. Hydraulic Performance Parameter to be tested |
|
Performance test shall be carried out to establish the following parameters:
| |
|
Rated Capacity |
| |
|
Rated Head |
| |
|
Power absorbed by the pump at rated duty |
| |
|
The efficiency of the pump at rated duty |
| |
|
Performance characteristics of the pump from closed valve condition to 120% of the rated flow |
If there is a specific agreement with the customer, the NPSH test will also be carried out by "the 3% head suppression" method. A brief description of this procedure is enclosed |
| |
|
| |
4. Mechanical Parameter to be tested |
|
The test shall include recording of the following parameters to check the mechanical integrity of the pump:
| |
|
Bearing Temperature |
| |
|
Temperature of Packing |
| |
|
Leakage of air |
| |
|
Leakage of water |
| |
|
Acoustic Emission |
| |
|
Vibration |
|
| |
|
| |
5. Staff |
|
A test supervisor possessing adequate experience in measuring operations will be entrusted with carrying out the test |
| |
|
| |
6. Test Equipment |
|
A list of equipment is currently used to carry out the test. |
