螺桿泵，螺旋泵，亦稱(chēng)“螺旋揚(yáng)水機(jī)”、“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(shí)，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(dòng)機(jī)通過(guò)變速裝置帶動(dòng)螺旋泵軸旋轉(zhuǎn)時(shí)，水就進(jìn)入葉片，沿螺旋型流道上升，直至出流。結(jié)構(gòu)簡(jiǎn)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(yáng)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(chǎng)合。中國(guó)從20世紀(jì)70年代開(kāi)始使用。螺旋泵的裝置包括原動(dòng)機(jī)、變速傳動(dòng)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(shí)，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(jí)一級(jí)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(jī)械能轉(zhuǎn)換為輸送液體的位能和動(dòng)能。 </p> <p> <br

螺桿泵液壓防反轉(zhuǎn)技能是通過(guò)螺桿泵液壓防反轉(zhuǎn)裝置來(lái)實(shí)現(xiàn)開(kāi)釋扭矩的。螺桿泵液壓防反轉(zhuǎn)裝置可以在螺桿泵停機(jī)后主軸反轉(zhuǎn)時(shí)，通過(guò)液壓抑動(dòng)鉗活塞伸出，推動(dòng)摩擦片卡緊制動(dòng)盤(pán)，使體系壓力敏捷低落。制動(dòng)鉗失去壓力后，主軸降速反轉(zhuǎn)，齒輪泵繼承開(kāi)始事情，制動(dòng)鉗再次孕育發(fā)生壓力卡緊制動(dòng)盤(pán)，如許時(shí)斷時(shí)續(xù)的卡緊—松開(kāi)—卡緊—松開(kāi)，直至主軸反轉(zhuǎn)扭矩卸至為零，消除寧?kù)o***。 </p> <p> 螺桿泵液壓防反轉(zhuǎn)裝置可實(shí)現(xiàn)內(nèi)部設(shè)置單向定壓卸載機(jī)構(gòu)，制動(dòng)力矩大，制動(dòng)安穩(wěn)可靠，散熱性好，扭矩可主動(dòng)開(kāi)釋?zhuān)恍枞斯ば杜ぞ?。這個(gè)裝置為**裝置，可以大概在原有驅(qū)動(dòng)裝置上舉行**，操縱簡(jiǎn)樸，**本錢(qián)低。 </p> <p> 立式單螺桿泵轉(zhuǎn)速和流量是線(xiàn)性干系，泵可定轉(zhuǎn)速而定流量。也可無(wú)級(jí)調(diào)速或多級(jí)變速來(lái)滿(mǎn)意用戶(hù)種種特性的要求，流量精度（1%），可作為計(jì)量泵用于實(shí)行室，配藥，配料等。壓力（揚(yáng)程）天生與“定子”螺旋導(dǎo)程（T）有關(guān)，一個(gè)導(dǎo)程（T）輸出壓力為0.6Mpa（60米揚(yáng)程）壓差級(jí)，二個(gè)導(dǎo)程為二級(jí)泵壓力為1.2Mpa（120米揚(yáng)程）。憑據(jù)工況必要任何一種型號(hào)都可以制造成，立式，斜置式，可移小車(chē)載式等型式的泵。立式單螺桿泵零件少，布局不龐大，以是折卸，維修簡(jiǎn)樸，縱然***利用也可在短期內(nèi)容易掌握。 </p> <p> <br /> </p><p> 二、螺桿泵的轉(zhuǎn)速選用 </p> <p> <br /> </p> <p> 螺桿泵的流量與轉(zhuǎn)速成線(xiàn)性關(guān)系，相對(duì)于低轉(zhuǎn)速的螺桿泵，高轉(zhuǎn)速的螺桿泵雖然能增加了流量和揚(yáng)程，但功率明顯增大，高轉(zhuǎn)速加速了轉(zhuǎn)子與定子間的磨耗，必定使螺桿泵過(guò)早失效，而且高轉(zhuǎn)速螺桿泵的定轉(zhuǎn)子長(zhǎng)度很短，極易磨損，因而縮短了螺桿泵的使用壽命。 </p> <p> <br /> </p> <p> 三、確保雜物不進(jìn)入泵體 </p> <p> <br /> </p> <p> 濕污泥中混入的固體雜物會(huì)對(duì)螺桿泵的橡膠材質(zhì)定子造成損壞，所以確保雜物不進(jìn)入泵的腔體是很重要的，很多污水廠在泵前加裝了粉碎機(jī)，也有的安裝格柵裝置或?yàn)V網(wǎng)，阻擋雜物進(jìn)入螺桿泵，對(duì)于格柵應(yīng)及時(shí)清撈以免造成堵塞。 </p> <p> <br />
