安裝和啟動把泵放置在盡量靠近產(chǎn)品的地方，使吸入管線路**短、配置零件數(shù)量減少，不要減少管路規(guī)格。為了延長隔膜壽命，要使泵盡量靠近被抽的液體，入口壓力超過10英尺（3米）液柱時需要安裝一套緩壓調整裝置來延長隔膜壽命。如果安裝硬管道，在泵和管道之間要用短的軟管來連接。軟管可以減緩管道的振動和扭曲，推薦使用一個穩(wěn)壓罐來進一步減小流體中的脈沖。供氣金屬泵供氣壓力不得超過125PSI（)，塑料泵供氣壓力不得超過100PSI（）。將泵的進氣口連接到有足夠容量并且壓力符合設計要求的氣源上。如果供氣線路是硬管道，在泵和管道之間連一短的軟管來減少扭曲。除了空氣進氣的蓋冒，空氣進氣管道、調壓過濾器的重量也必須通過某種方法支撐。如果不支撐管道也許會損壞泵。必須安裝壓力調節(jié)閥來確保供氣壓力不超過規(guī)定的范圍。操作前須知泵工作前，檢察所有固定物以防松弛，將松的地方擰緊以免泄露，用隨泵所附的卡中所介紹的方法固定。進氣和啟動啟動時，空氣閥打開約1/2到3/4圈。泵啟動后，打開空氣閥增加空氣流量以達到要求的流量。排氣如果膜片壞了，抽取的液體或氣體會進入泵的空氣口，被排入大氣中，當抽取危險或有毒物質時，需要管道排到合適的地方作安全處理。壓力表的發(fā)展背景和行業(yè)地位。</p><div
