排污工作全部結(jié)束。水垢影響編輯鎂離子和酸式碳酸鹽。有碳酸鹽的生成。另外，形成鐵銹。由于銹垢的產(chǎn)生，換熱效果下降。使換熱效果失去作用。節(jié)約能源、設(shè)備的使用壽命。影響(1)壓縮機(jī)組的影響：由于冷卻水質(zhì)差，在冷卻器中形成的污垢熱阻大，使冷卻器不能正常運(yùn)行，了壓縮機(jī)中每一級(jí)的進(jìn)口、出口參數(shù)偏離，影響了級(jí)與級(jí)之間的匹配性能，了壓縮機(jī)的效率，了加工氣量，了機(jī)組的能耗，使機(jī)組的整體性能下降。終使空分裝置的產(chǎn)量下降，能耗，運(yùn)行周期縮短和變工況調(diào)節(jié)范圍縮小。(2)冷凍機(jī)的影響：冷卻水形成的污垢熱阻大，使冷凍機(jī)中的冷凝器不能正常運(yùn)行。冷媒的冷凝壓力、溫度升高，使冷凍機(jī)的制冷量下降，空氣出空冷塔進(jìn)分子篩純化器的溫度升高。

俗稱耐壓。常用可控硅的VRRM/VDRM一般為幾百伏到一千伏。⒊控制極觸發(fā)電流（IGT），俗稱觸發(fā)電流。常用可控硅的IGT一般為幾微安到幾十毫安。在規(guī)定溫度和散熱條件下，允許通過(guò)陰極和陽(yáng)極的電流平均值。封裝形式編輯常用可控硅的封裝形式有TO-TO-TO-202AB、TO-TO-220ABC、TO-、SOT-TO-TO-SOT-SOT23-3L等用途編輯普通晶閘管基本的用途就是可控整流。大家熟悉的二極管整流電路屬于不可控整流電路。如果把二極管換成晶閘管，就可以構(gòu)成可控整流電路。以簡(jiǎn)單的單相半波可控整流電路為例，在正弦交流電壓U2的正半周期間。
