class="title">詳細(xì)說明</p><div id="hb7t9sz" class="box"><p><p> 單雙螺桿泵和普通的工作原理及產(chǎn)品介紹，螺桿泵是利用螺桿的回轉(zhuǎn)來吸排液體的。螺桿為主動(dòng)螺桿，由原動(dòng)機(jī)帶動(dòng)回轉(zhuǎn)，兩邊的螺桿為從動(dòng)螺桿，隨主動(dòng)螺桿作反向旋轉(zhuǎn)。主、從動(dòng)螺桿的螺紋均為雙頭螺紋。由于各螺桿的相互嚙合以及螺桿與襯筒內(nèi)壁的緊密配合，在泵的吸入口和排出口之間，就會(huì)被分隔成一個(gè)或多個(gè)密封空間。隨著螺桿的轉(zhuǎn)動(dòng)和嚙合，官方螺桿泵高性價(jià)比的選擇，這些密封空間在泵的吸入端不斷形成，將吸入室中的液體封入其中，并自吸入室沿螺桿軸向連續(xù)地推移至排出端，將封閉在各空間中的液體不斷排出，猶如一螺母在螺紋回轉(zhuǎn)時(shí)被不斷向前推進(jìn)的情形那樣，這就是螺桿泵的基本工作原理。 </p> <p> <br /> </p> <p> 螺桿泵有單螺桿泵、雙螺桿泵和三螺桿泵。 </p> <p> <br /> </p> <p> 螺桿泵的工作原理是：螺桿泵工作時(shí)，液體被吸入后就進(jìn)入螺紋與泵殼所圍的密封空間，當(dāng)主動(dòng)螺桿旋轉(zhuǎn)時(shí)，螺桿泵密封容積在螺牙的擠壓下提高螺桿泵壓力，并沿軸向移動(dòng)。由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的。 </p> <p> <br /> </p> <p> 螺桿泵特點(diǎn)為：螺桿泵損失小，經(jīng)濟(jì)性能好。壓力高而均勻，流量均勻，轉(zhuǎn)速高，能與原動(dòng)機(jī)直聯(lián)。 </p> <p> <br /> </p> <p> 螺桿泵可以輸送潤滑油，官方螺桿泵高性價(jià)比的選擇，官方螺桿泵高性價(jià)比的選擇，輸送燃油，輸送各種油類及高分子聚合物，用于輸送黏稠液體。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="官方螺桿泵高性價(jià)比的選擇"

點(diǎn)腐蝕是由局部電作用引起的，腐蝕從金屬表面開始，***產(chǎn)生凹坑，凹坑可能會(huì)被腐蝕產(chǎn)物覆蓋，結(jié)成瘤狀形的硬疤，疤的下面就是一個(gè)點(diǎn)蝕坑。點(diǎn)蝕經(jīng)常發(fā)生在金屬表面上有停滯或緩慢流動(dòng)介質(zhì)的區(qū)域。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 晶間腐蝕先從金屬表面晶粒之間的邊緣開始，腐蝕介質(zhì)逐步滲人到金屬的深處，破壞了金屬晶粒之間的結(jié)合力，在金屬表面不會(huì)留下宏觀的跡象，從表面不易發(fā)現(xiàn)，但金屬材料的強(qiáng)度和塑性幾乎完全喪失，只要在很小的外力作用下就可能破壞。比如，不銹鋼經(jīng)過嚴(yán)重晶間腐蝕后，表面看起來仍十分光滑，但只要用錘輕輕敲擊，它就會(huì)碎成粉末。由于設(shè)備在工作過程中晶間腐蝕不容易被發(fā)現(xiàn)，所以它是一種危險(xiǎn)性比較大的腐蝕破壞形式。 </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="官方螺桿泵高性價(jià)比的選擇"

空泡腐蝕是金屬與液體介質(zhì)之間作高速相對(duì)運(yùn)動(dòng)時(shí)，液體介質(zhì)對(duì)金屬產(chǎn)生的沖擊加腐蝕的一種腐蝕形式，空泡腐蝕的結(jié)果使金屬表面產(chǎn)生蜂窩狀的腐蝕坑。離心螺桿泵葉輪等通常會(huì)遭受空泡腐蝕。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 螺桿泵輸送帶有固體顆粒的懸浮液時(shí)，由于固體粒子在螺桿泵的過流部件表面上的沖刷，常常使這些部件產(chǎn)生嚴(yán)重的磨損，稱為沖刷腐蝕。如螺桿泵的葉輪產(chǎn)生沖刷腐蝕后會(huì)使螺桿泵的揚(yáng)程和效率***降低，甚至使螺桿泵無法工作，必須更換新的葉輪。此外，螺桿泵的汽蝕是機(jī)械剝蝕和腐蝕共同作用的結(jié)果，也會(huì)給螺桿泵帶來嚴(yán)重?fù)p壞。
