Leak testing issues
Thread Content
When performing a pressure test for leak detection on the unit, should the pump and its components, including the filters, also be subject to such a test? I think it will damage the filter.
Generally, it is possible to operate with an empty cavity without installing an inner core before compression.
Our pump was installed right after it was purchased; otherwise, we would have to take it apart! Isn’t this a bit troublesome?
In principle, to flush the pipeline it is necessary to remove the filter element or replace the filter with a bypass; pressure testing and airtightness tests should be carried out after this has been done. This is just my personal opinion; I welcome any corrections from those with more experience. Thank you
There is no issue with the pressure applied to the filter; it’s best to fill it with water in the direction of the medium flow.
During the actual suppression process, I didn’t see anyone dismantle it.
The design pressure of the filter is generally the same as that of the pipeline, so there should be no risk of damage to the filter when pressure is applied.
It is recommended to clean the filter once after pressurizing it, before driving
Agree with the second floor – during pressure testing, the filter screen should be removed first to test the cavity, and it should be reinstalled after the testing is complete.
It’s common sense to remove the filter element first and then purge it after applying pressure. If you see anything that isn’t done properly, check the quotes from engineering companies – don’t let them deceive you
There’s no need to remove it; it’s fine to conduct pressure testing together, as the pressurization process will not cause any damage to the filter.
Generally, short-circuiting should be used as a substitute, or pressure testing should be carried out in sections; the segmentation must be done properly, and the valves should be closed for each section during pressure testing.
If this pump is to be used for filling water or applying pressure, a filter must be installed, and the filter screen should be removed and cleaned after use. If it is only used for purging and pressure testing, temporary blind flanges should be placed on the pump’s inlet and outlet, and the inlet filter also needs to be removed and cleaned after individual testing of the pump as well as during hydraulic testing.
During pressure testing and airtightness tests, the filter elements are generally not removed; equipment such as instruments must be taken off and replaced with short tubes
