GC型臥式鍋爐給水離心泵特點(diǎn)：1.GC型臥式鍋爐給水離心泵水力模型先進(jìn)，效率高，性能范圍廣。GC型臥式鍋爐給水離心泵運(yùn)行平穩(wěn)，噪音低。GC型臥式鍋爐給水離心泵的軸封采用軟填料密封，安全可靠、結(jié)構(gòu)簡單，維修方便快捷。GC型臥式鍋爐給水離心泵技術(shù)參數(shù)：GC型臥式鍋爐給水離心泵流量：6-55m3/h；揚(yáng)程：46-31m；功率：3-75KW；轉(zhuǎn)速：295r/min；口徑：4-1；溫度范圍：11℃；工作壓力：2.7Mpa。
一般來說，對于高品質(zhì)的控制閥，如果使用不久便出現(xiàn)故障，其原因往往是由于選型錯誤、安裝不當(dāng)、使用欠妥造成的。對于這類故障，只要針對原因予以糾正，只需很少零件甚至無需任何零件即可很快解決問題。而控制閥經(jīng)過長期工作而發(fā)生的故障，一般是由于閥門零件疲勞損壞造成的。及時發(fā)現(xiàn)故障，予以妥善維修，便能以較低的成本延長控制閥的使用壽命。實踐經(jīng)驗中，由于合理的維護(hù)保養(yǎng)，使高品質(zhì)控制閥在惡劣工況下正常工作數(shù)十年的例子屢見不鮮。
SBS的注入口要在膜元件的上游，設(shè)置距離要保證在進(jìn)入膜元件有29秒的反應(yīng)時間。推薦使用適當(dāng)?shù)脑诰€攪拌裝置。SBS脫氯反應(yīng)：Na2S2O5（偏亞硫酸鈉）+H2O＝2NaHSO3（亞硫酸氫鈉）NaHSO3+HOCl＝NaHSO4（硫酸氫鈉）+HCl（鹽酸）NaHSO3+Cl2+H2O＝NaHSO4+2HCl采用SBS脫氯的好處是在大系統(tǒng)中比碳過濾器的投資較少，反應(yīng)副產(chǎn)物及殘余SBS易于被RO脫除。SBS脫氯的缺點(diǎn)是需要人工混合小體積的藥劑，在脫氯系統(tǒng)沒有設(shè)計足夠的監(jiān)測控制儀器時增加了氯對膜的威脅，而且在少數(shù)情況下進(jìn)水中存在硫還原菌（SBR），亞硫酸會成為細(xì)菌營養(yǎng)幫助細(xì)菌的繁殖。
KC2CY不銹鋼齒輪泵用途詳解KC2CY不銹鋼齒輪泵泵材質(zhì)為34不銹鋼，（316或316L材質(zhì)的需要提前訂做）電機(jī)有普通和防爆兩種，不銹鋼齒輪泵用于衛(wèi)生要求條件較高或輸送的介質(zhì)有腐蝕性的場合，這種不銹鋼油泵流量大到6立方/小時。結(jié)構(gòu)：泵體、泵蓋、齒輪、軸承套以及軸端密封等零部件組成。油泵齒輪均經(jīng)氮化處理，有較高的硬度和耐磨性，與軸一同安裝在軸套內(nèi)。泵內(nèi)所有運(yùn)轉(zhuǎn)部件均利用其輸送的介質(zhì)潤滑。
