先檢查過程中反滲透純水設備不能開機，依次檢查的流程是，檢查電源插頭是否插好，電源是否有電。檢查電源開關連接線是否脫落，重新連接電源線。系統(tǒng)顯示無水并發(fā)出報警聲表明進水水壓低于設定值。請檢查水源是否打開，系統(tǒng)是否有進水，或自來水水壓是否低于0.1MPa。若有，請改善進水情況至合適水壓。若進水情況正常，則需檢查預處理濾芯是否堵塞，若有堵塞，請對預處理濾芯進行清洗或更換。

反滲透主機系統(tǒng)可以叫做反滲透裝置，是反滲透水處理設備的心臟部分，其主要由反滲透膜元件、膜殼（壓力容器）、支架等組成。經反滲透裝置處理的水，能去除絕大部分無機鹽、有機物、微生物等雜質。反滲透系統(tǒng)設計的合理性直接關系到整個項目的投資費用、經濟效益、使用壽命以及操作流程等。 </p> <p> 反滲透膜是一種由壓力驅動的新型分離膜，在壓力推動下，溶液中的水分子透過膜，而其它分子、離子、細菌、病du等被截留，從而達到制取純水的目的。反滲透膜的孔徑小于1nm(納米)，能有效去除二價離子，對一價離子的去除率也可達95～99%；對低分子量有機物的去除率可達100％；反滲透系統(tǒng)能夠除去原水中99%以上的礦物質、細菌、病du、熱原及細菌內du素等。 </p> <p> <br /> </p> <p> <br /> 反滲透設備如果安裝在室外，必須有防凍措施。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="徐匯區(qū)反滲透設備廠家,反滲透設備"

反滲透設備管路材質選擇，要考慮內部和外部的問題，內部就是水質對管路的腐蝕，外部就是運行環(huán)境。反滲透設備運行環(huán)境決定管路外部腐蝕情況，如果運行環(huán)境較好，一般采用表面涂層（如上油漆或者鍍鋅等）即可。水質對管路的腐蝕要考慮余氯、化學品、PH值、溫度等。我們一般常用的有UPVC、不銹鋼等。 </p> <p> <br /> </p> <p> 不銹鋼的基本優(yōu)點是對一般腐蝕都有很好的耐性，不銹鋼很少產生電流腐蝕和應力腐蝕破壞，但不銹鋼卻容易發(fā)生點蝕和縫隙腐蝕，點蝕反映金屬受到局部侵蝕，在其表面上造成凹陷孔洞，如果氧化鉻鈍化層被破壞，氯離子就會攻擊裸露的金屬形成點蝕?？p隙腐蝕與小孔、墊片表面、沉積物周圍以及螺絲下的裂縫等處的一小撮靜止水所導致的點蝕有關。為避免發(fā)生膜系統(tǒng)高壓管路的點蝕及縫隙腐蝕，建議如下： </p> <p> 一般水源，可以選用304不銹鋼； </p> <p> 原水含鹽量在2-5000PPM時，建議選用含碳量小于0.08%的316不銹鋼； </p> <p> 原水含鹽量在5-7000PPM時，建議選用含碳量小于0.03%的316L不銹鋼； </p> <p> 原水含鹽量在7-30000PPM時，建議選用含鉬量為4%-5%的904L不銹鋼。 </p> <p> <br />

2、反滲透預處理需考慮后期運行過程中水質變化，防止原水水質波動影響反滲透設備穩(wěn)定運行; </p> <p> 3、反滲透預處理工藝能高效、穩(wěn)定運行，同時盡量簡化流程，降低投資和運行成本。 </p> <p> 反滲透主機系統(tǒng)可以叫做反滲透裝置，是反滲透水處理設備的心臟部分，其主要由反滲透膜元件、膜殼（壓力容器）、支架等組成。經反滲透裝置處理的水，能去除絕大部分無機鹽、有機物、微生物等雜質。反滲透系統(tǒng)設計的合理性直接關系到整個項目的投資費用、經濟效益、使用壽命以及操作流程等。徐匯區(qū)反滲透設備廠家</p></p><br /><p>文章來源地址:
