腐蝕是材料與環(huán)境發(fā)生反應(yīng)的結(jié)果。金屬材料與環(huán)境通常發(fā)生化學(xué)反應(yīng)或電化學(xué)反應(yīng)，非金屬材料與環(huán)境則會發(fā)生溶脹、溶解、老化等反應(yīng)。 (二）腐蝕的類型及機理 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 1.按腐蝕的機理分為化學(xué)腐蝕和電化學(xué)腐蝕兩大類 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 化學(xué)腐蝕是指金屬與干燥的氣體或非電解質(zhì)溶液產(chǎn)生化學(xué)作用而引起的腐蝕。化學(xué)腐蝕通常為干腐蝕，腐蝕速度相對較小。如碳鋼在鑄造、鍛造、熱處理過程中發(fā)生的高溫氧化以及鋁在無水乙醇中的腐蝕等均屬于此類腐蝕。實際上單純的化學(xué)腐蝕是相當(dāng)少的，一些干燥介質(zhì)中如混人水分常會由化學(xué)腐蝕轉(zhuǎn)化為電化學(xué)腐蝕。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 電化學(xué)腐蝕是指金屬與電解質(zhì)溶液發(fā)生電化學(xué)反應(yīng)而產(chǎn)生的破壞，反應(yīng)過程均包括陽極反應(yīng)和陰極反應(yīng)兩個過程，原裝螺桿泵歡迎咨詢，原裝螺桿泵歡迎咨詢，腐蝕過程中伴有電流的流動，即電子和離子的運動。金屬在酸、堿、鹽等化學(xué)溶液和土壤、海水、潮濕的大氣中的腐蝕均屬于此類腐蝕。通常情況下，原裝螺桿泵歡迎咨詢，電化學(xué)腐蝕要比化學(xué)腐蝕強烈得多，金屬的腐蝕破壞大多數(shù)也是由電化學(xué)腐蝕引起的。 </p> <p> <br /> </p> <p> <br /> 對采用機械密封的，則要非常小心翼翼地進行，否則極易造成動、靜環(huán)的破碎。原裝螺桿泵歡迎咨詢</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="原裝螺桿泵歡迎咨詢,螺桿泵"

style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="原裝螺桿泵歡迎咨詢,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876901611328/4013793.jpg"></div><p style="text-indent:25px">常見螺桿泵的特點和應(yīng)用，螺桿泵依靠螺桿相互嚙合（或螺桿與定子嚙合）空間的容積變化來輸送液體。當(dāng)螺桿轉(zhuǎn)動時吸入腔一端作軸向移動，使吸入腔的容積增大，壓力降低，液體在壓差作用下沿吸入管進入吸入腔。隨著螺桿的轉(zhuǎn)動，密封腔內(nèi)的液體連續(xù)而均勻地沿軸向移動到排出腔，由于排出腔一端的容積逐漸縮小，即將液體排出。螺桿泵的特點是流量和壓力脈動小、運轉(zhuǎn)平穩(wěn)、噪聲低、效率高、壽命長、有較強的自吸能力而且結(jié)構(gòu)簡單緊湊；其突出的優(yōu)點是輸送介質(zhì)時不形成渦流、對介質(zhì)的粘性不敏感，可輸送高粘度介質(zhì)。螺桿泵按螺桿數(shù)目分為單螺桿泵、雙、三和五螺桿泵。單螺桿泵的結(jié)構(gòu)為單頭陽螺旋轉(zhuǎn)子在特殊的雙頭陰螺旋定子內(nèi)偏心地轉(zhuǎn)動（定子是柔性的），能沿泵中心線來回擺動，與定子始終保持嚙合；雙螺桿泵結(jié)構(gòu)為有兩根同樣大小的螺桿軸，一根為主動軸，一根為從動軸，通過齒輪傳動達到同步旋轉(zhuǎn)；三螺桿泵結(jié)構(gòu)為有一根主動螺桿和兩根與之相嚙合的從動螺桿所構(gòu)成；五螺桿泵的結(jié)構(gòu)為定子內(nèi)裝有五根左、右旋的螺桿軸，螺桿的共軛齒廓上有一段漸開線，它起主動螺桿泵向從動螺桿傳遞運動的作用。</p><p> 螺桿泵，螺旋泵，亦稱“螺旋揚水機”、“阿基米德螺旋泵”。利用螺旋葉片的旋轉(zhuǎn)，使水體沿軸向螺旋形上升的一種泵。由軸、螺旋葉片、外殼組成。抽水時，將泵斜置水中，使水泵主軸的傾角小于螺旋葉片的傾角，螺旋葉片的下端與水接觸。當(dāng)原動機通過變速裝置帶動螺旋泵軸旋轉(zhuǎn)時，水就進入葉片，沿螺旋型流道上升，直至出流。結(jié)構(gòu)簡單，制造容易，流量較大，水頭損失小，效率較高，便于維修和保養(yǎng)，但揚程低，轉(zhuǎn)速低，需設(shè)變速裝置。多用于灌溉、排澇，以及提升污水、污泥等場合。中國從20世紀70年代開始使用。螺旋泵的裝置包括原動機、變速傳動裝置和螺旋泵三部分，如圖1所示，具體是由螺旋葉片1、泵軸2、軸承座 </p> <p> <br /> </p> <p> 螺旋泵裝置 </p> <p> 3和外殼4組成的。螺旋泵傾斜裝在上、下水池之間，螺旋泵的下端葉片浸入到水面以下。當(dāng)泵軸旋轉(zhuǎn)時，螺旋葉片將水池中的水推入葉槽，水在螺旋的旋轉(zhuǎn)葉片作用下，沿螺旋軸一級一級往上提升，直至螺旋泵的出水口。螺旋泵只改變流體的位能，它不同于葉片式水泵將機械能轉(zhuǎn)換為輸送液體的位能和動能。 </p> <p> <br />

2、填料壓緊程度的調(diào)整 </p> <p> 采用填料密封結(jié)構(gòu)的泵，需經(jīng)常檢查介質(zhì)匯漏情況，以略有介質(zhì)滴出為宜。調(diào)整填料壓蓋，若壓得過緊會使填料的相對轉(zhuǎn)動處因過熱而加磨損。更換填料時，應(yīng)全部更換，軸若磨損嚴重也應(yīng)更換。 </p> <p> <br /> </p> <p> <br /> </p> <p> 拆卸與零件的更換 </p> <p> <br /> </p> <p> 1、泵在拆卸前，須先行脫離動力端，以防止人身***的發(fā)生。 </p> <p> <br /> </p> <p> 2、拆卸泵頭，卸下泵頭固定螺母，取下泵頭。如無泵頭而只有輸出法蘭的泵，可不用拆下法蘭，便于下一步拉出定子。需要更換定子時拆下此法蘭。 </p> <p> <br /> </p> <p> 3、借助工具拉出定子。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 主要工作部件是偏心螺桿（轉(zhuǎn)子）和固定的襯套（定子）。原裝螺桿泵歡迎咨詢</p><p style="text-indent:25px">單螺桿泵適合輸送敏性物品和易受離心力等破壞的物品.原裝螺桿泵歡迎咨詢</p><p
