Subject: the receiver, grade level ?? Не уверенна в правильности терминологии. Речь идет о пароконденсатных системах:the receiver, grade level??The static elevation can be increased by elevating the receiver that collects the condensate. However, if the condensate returns are low or below grade level, this factor is difficult to change. Sometimes the only solution is to put the condensate unit in a pit deep enough to provide the necessary NPSHA. In an existing system, however, there is often no way to change the level of return lines. В этом случае, следует использовать расширительный бак с отводом пара. Заранее спасибо |
