Subject: fill pressure What is fill pressure - давление заполнения?? Maintaining sufficient NPSH to avoid pump cavitation usually is not a serious factor in closed hot or chilled water systems because these systems are pressurized. The system fill pressure can usually be increased to satisfy the NPSHR of the pump. Заранее спасибо |
