設(shè)計(jì)高轉(zhuǎn)速的螺桿鉆應(yīng)采用小齒數(shù)比螺桿馬達(dá)，而設(shè)計(jì)低速大扭矩的螺桿鉆應(yīng)采用大齒數(shù)比螺桿馬達(dá)。隨著轉(zhuǎn)子定子齒數(shù)比的增大,其效率逐漸趨于下降；螺桿鉆的輸出扭矩取決于通過馬達(dá)的工作壓力降，輸出轉(zhuǎn)速取決于通過螺桿馬達(dá)工作介質(zhì)的流量。鉆探時(shí)，仍然需要鉆探機(jī)、泥漿泵、鉆桿和鉆塔等常規(guī)鉆探裝備。施工定向鉆孔時(shí)，河南鋼板樁打樁機(jī)價(jià)格多少，要借助定向儀給造斜工具定向。與螺桿鉆配套使用的造斜工具有彎接頭、彎外管和偏心塊等。采用螺桿鉆施工定向孔能提高鉆孔質(zhì)量，提供地質(zhì)資料，節(jié)約進(jìn)尺，降低成本，河南鋼板樁打樁機(jī)價(jià)格多少，解決許多無法施工的工程難題，河南鋼板樁打樁機(jī)價(jià)格多少，因此，它是鉆探工程的一種特種工具。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河南鋼板樁打樁機(jī)價(jià)格多少"

采用螺桿鉆具鉆探與常規(guī)鉆探相比有許多優(yōu)點(diǎn)，如鉆桿磨損大幅度下降，鉆速高。它是打定向孔的主要器具，在鉆探領(lǐng)域已發(fā)揮作用。1955年，美國克利斯坦森礦山鉆探制品公司根據(jù)莫因諾原理開始研究,于1964年首先取得成功,定名為“戴納鉆”;蘇聯(lián)于70年代初研究成功“凸”型螺桿鉆具;中國地礦部勘探技術(shù)研究所于80年代初研制螺桿鉆具成功。至今生產(chǎn)螺桿鉆具的有美國、俄羅斯、中國、德國等。螺桿鉆具**早是用來打垂直孔，主要用來打各種定向孔和特種工程孔（如礦井凍結(jié)孔）。

轉(zhuǎn)速很快降低，嚴(yán)重時(shí)則完全停止轉(zhuǎn)動(dòng)，馬達(dá)損壞。（馬達(dá)的一個(gè)導(dǎo)程為一級）現(xiàn)場使用的泥漿流量應(yīng)在推薦的使用范圍內(nèi)，否則將影響馬達(dá)效率，甚至加大磨損。螺桿馬達(dá)的性能參數(shù)是螺桿鉆具的主要性能參數(shù)。馬達(dá)的理論輸出扭矩和馬達(dá)壓降成正比，輸出轉(zhuǎn)數(shù)與輸入泥漿流量成正比，隨著負(fù)荷的增加鉆具轉(zhuǎn)數(shù)降低，所以只要控制地面上的壓力表的讀數(shù)和泵的流量，就能控制井下鉆具的扭矩和轉(zhuǎn)速。螺桿鉆具是一種以鉆井液為動(dòng)力，把液體壓力能轉(zhuǎn)為機(jī)械能的容積式井下動(dòng)力鉆具。當(dāng)泥漿泵泵出的泥漿流經(jīng)旁通閥進(jìn)科馬達(dá)，在馬達(dá)的進(jìn)、出口形成一定的壓力差，推動(dòng)轉(zhuǎn)子繞定子的軸線旋轉(zhuǎn)，并將轉(zhuǎn)速和扭矩通過萬向軸和傳動(dòng)軸傳遞給鉆頭，從而實(shí)現(xiàn)鉆井作業(yè)。
