Y型過濾器建設項目、籃式過濾器公稱壓力
按照Y型過濾器組成部分、籃式過濾器管路可能出現(xiàn)的最高壓力確定過濾器的壓力等級示範推廣,也可通過技術(shù)協(xié)議要求實踐者,考慮進(jìn)出口管路的統(tǒng)一性,選擇與出口管路中最高壓力相匹配的壓力等級過濾器重要意義,實際適用最高壓力與介質(zhì)濕度關(guān)系如下:
Nominal pressure: Inaccordance with the filter pipe maximum pressure that may arise to determine the pressure of grading filters can also pass Have the technical requirements in the agreement, to consider the unity of the import and export pipelines, select and export pipeline to match the highest pressure The pressure of grading filters. The practical application of the maximum pressure and humidity of the relationship between media are as follows:
