water suppression test few things to note :
First,[link widoczny dla zalogowanych], be sure to test water pressure :
sea after transformation Pressure test must be done . To avoid leakage .
Second, how do suppress the test?
1. close the valve before the water meter , water meter to avoid injury when suppressed .
2. to all the outlets at the terminal block on the wire , while the water system,[link widoczny dla zalogowanych], water injection,[link widoczny dla zalogowanych], water injection rate at this time should not be too fast, in order to facilitate pipeline from the air .
3. with suppressed pump pressure,[link widoczny dla zalogowanych], not too fast, in order to facilitate the discharge of air .
4. waterway system rose 8Mpa, stop the pressure to observe whether there is water leakage in the joints .
5. regulator , the pressure drop within half an hour less than 0.02MPa in compliance.
pressure test over, must do original records.
Third, pressure testing Note :
1, after water pressure test valve should be closed , otherwise will not be on the pressure .
2, wire blocking can not have leaks , because the wire plug weld leakage can mask other problems .
3, when the water valve leakage suppression , the phenomenon may arise out of pressure in case of such a situation,[link widoczny dla zalogowanych], to remove the water meter ,[link widoczny dla zalogowanych], then press on the pressure test is completed .

Headphones are a pair of small loudspeakers, or less commonly a single speaker, with a way of holding them close to a user's ears and a means of connecting them to a signal source such as an audio amplifier, radio, CD player or portable media player. They are also known as stereophones, headsets or, colloquially cans. The in-ear versions are known as earphones or earbuds.
