Switch to English1、所有的水路改造完畢都要進行打壓試驗，打壓是為了檢驗水路完畢后是否有漏水現象。自來水一般1.5個大氣壓下運行，打壓實驗一般6個壓力即可，穩壓后，30分鐘之內不掉壓為正常。(打壓時間需要在穩壓后計算)
2、只要是更換暖氣和管道，或者新做地熱之后，也應該進行打壓測試，6個壓(0.6Mpa)即可，因為6個壓力本身就是試驗壓力，高層住宅較好達到8個大氣壓。管子里面有空氣的原因，剛開始壓力不穩定是正常的，不過降到需壓力后，穩定的維持在需的壓力下30~40分鐘即可，穩壓后，半個小時內的壓力降不超過0.05Mpa為合格。
3、壓力太大(超過10個壓)和打壓時間過長(超過2個小時)對管道都不好。
4、如果持續30分鐘之內減壓了0.05個壓，這是正?，F象，如果后來壓力持續恒定，可以判斷合格。如果壓力持續下降，應該重新測試。
1, all the waterway transformation should be carried out to suppress the test, pressure is to test the water after the completion of whether there is water leakage. Tap water generally 1.5 atmospheric pressure to run, pressure experiments generally 6 pressure can, regulator, within 30 minutes without falling pressure is normal. (Pressure must be calculated after the voltage regulator)
2, as long as the replacement of heating and piping, or do new geothermal, the pressure test should be carried out, 6 pressure (0.6Mpa) can, because the pressure is itself 6 test pressure, high-rise residential is best to 8 atmospheres. Pipe inside the air, the beginning of the pressure instability is normal, but reduced to a certain pressure, the stability of the maintenance of a certain pressure 30 to 40 minutes, the regulator, the pressure drop within half an hour More than 0.05Mpa for qualified.
3, the pressure is too large (more than 10 pressure) and pressure for too long (more than 2 hours) on the pipeline are not good.
4, if the decompression within 30 minutes of the 0.05 pressure, which is a normal phenomenon, if the pressure continued to be constant, you can determine the pass. If the pressure continues to drop, it should be retested.
