【螺桿泵】主要依靠螺桿轉(zhuǎn)動時泵腔容積的變化吸入和輸送水體的一種容積泵。螺桿泵有單螺桿、雙螺桿和多螺桿等類型。在農(nóng)業(yè)中使用的是單螺桿泵，其泵腔由鋼制螺桿和固定安裝在泵殼內(nèi)的橡膠套管組成。具有單螺距的螺桿在具有雙螺距內(nèi)螺旋的套管內(nèi)轉(zhuǎn)動，兩者間形成的空腔由吸入端移動到出口端，從而形成連續(xù)的水流。由于其結(jié)構(gòu)簡單、體積小、拆裝容易、工作可靠，自吸性能好，多用于移動式噴灌系統(tǒng)。
【手動隔膜泵】 用于低揚程、小流量的提水作業(yè)，由泵體、進出水管、進出水閥門、隔膜和推拉桿等組成。泵體可由一個或兩個泵腔組成。具有兩個泵腔的隔膜泵，其隔膜設(shè)置在泵體的中央，或兩個隔膜分別裝在分隔的兩個泵腔外側(cè)。工作時由兩人用手操縱與隔膜相連的推拉桿，推動隔膜作壓進和張開的往復(fù)運動，使兩個泵腔的容積交替擴大和縮小。當泵腔擴大時，壓力減小，進水閥開啟出水閥關(guān)閉，水從進水管流入泵腔；當泵腔縮小時，壓力加大，進水閥關(guān)閉，出水閥開啟，泵腔內(nèi)的水從排水管流出，兩個泵腔交替吸水和排水，每小時可提水10～20噸。
【拉桿式活塞泵】 由畜力原動機、風力機或內(nèi)燃機等驅(qū)動，常在放牧場上從井中提水時使用。由泵缸、活塞、進出水管、進出水閥門、拉桿和傳動裝置等組成?；钊窟B接在它上面的拉桿帶動，在泵缸內(nèi)作上下往復(fù)運動。當活塞向上運動時，進水閥開啟，進水管中的水進入泵缸，同時出水閥關(guān)閉，活塞上面的水被帶動向上提升；當活塞向下運動時，進水閥關(guān)閉，出水閥開啟，泵缸內(nèi)的水由出水閥升到活塞上面，如此反復(fù)進水和提升，使水不斷從排水管排出。
齒輪泵使用技術(shù)之高粘度泵的正確使用方法：鄭州巴特齒輪泵主要用于高粘度等工業(yè)生產(chǎn)使用。
1、高粘度轉(zhuǎn)子泵工作時物料粘度、流量、壓力增大容易引起電機超負荷，應(yīng)經(jīng)常檢查壓力表、安全閥、過電流保護裝置是否正常。
2、高粘度轉(zhuǎn)子單螺桿泵原則上僅可在選型、訂購時所依據(jù)的壓力、流量、粘度、溫度、PH值、含固量等條件下運行，盡可能避免在超出限制條件的工況中運行。
3、高粘度轉(zhuǎn)子泵有配置保溫裝置的泵，開機前應(yīng)先通熱水預(yù)熱，待泵溫升至輸送工藝要求后啟動。關(guān)機前應(yīng)先停泵再關(guān)熱水。
4、高粘度轉(zhuǎn)子泵配有冷卻水的機械密封裝置，在開機前應(yīng)先開冷卻水，后開泵，并經(jīng)常觀察冷卻水是否正常，嚴禁無冷卻水運轉(zhuǎn)時運行。
5、高粘度轉(zhuǎn)子泵安裝后一年內(nèi)應(yīng)每月清洗過濾器、過濾網(wǎng)，避免阻塞，導(dǎo)致泵不能正常運行。盡量避免使用Y型管道過濾器。
