雙螺桿泵,不銹鋼雙螺桿泵
一、不銹鋼雙螺桿泵概述
雙螺桿泵的種類較多，它們是由不同的螺桿螺旋形面（即螺旋齒形曲線也稱型線）構成不同類型的雙螺桿泵。雙螺桿泵有密封型和非密封型兩大類。 雙螺桿泵作為一種容積式泵，泵內吸入室應與排出室嚴密地隔開。因此，泵體與螺桿外圓表面及螺桿與螺桿間隙應盡可能小些。同時螺桿與泵體、螺桿與螺桿間又相互形成密封腔，保證密閉，否則就可能有液體從間隙中倒流回去。
雙螺桿泵可分為內置軸承和外置軸承兩種形式。在內置軸承的結構型式中軸承由輸送物進行潤滑。外置軸承結構的雙螺桿泵工作腔同軸承是分開的。由于這種泵的結構和螺桿間存在的側間隙，它可以輸送非潤滑性介質。此外，調整同步齒輪使得螺桿不接觸，同時將輸出扭矩的一半傳給從動螺桿。正如所有螺桿泵一樣，外置軸承式雙螺桿泵也有自吸能力，而且多數泵輸送元件本身都是雙吸對稱布置，可消除軸向力，也有很大的吸高。
泵的這些特性使它在油田化工和船舶工業中得到了廣泛的應用。外置軸承式雙螺桿泵可根據各種使用情況分別采用普通鑄鐵、不銹鋼等 不同材料制造。輸送溫度可達 250 o C 。泵具有不同方式的加熱結構，理論流量可達 2000 立方米 / 小時。
二、不銹鋼雙螺桿泵的特點：
無攪拌、無脈動、平穩的輸送各種介質，由于泵體結構保證泵的工作元件內始終存有泵送液體作為密封液體，所有的泵有很強的自吸能力，且能汽液混輸。
泵的特殊設計保證了泵有高的吸入性能即很小的 NPSHr 值。采用獨立潤滑的外置軸承，允許輸送各種非潤滑性介質。 臥式、立式、帶加熱套等各種結構型式齊全，可以輸送各種清潔的不含固體顆粒的低粘度或高粘度介質，選用正確的材質，甚至可以輸送許多腐蝕性介質。
三、. 不銹鋼雙螺桿泵的用途
由雙螺桿泵的原理知道，對于外置軸承的雙螺桿泵，通過軸承定位，兩根螺桿在襯套中互不接觸，齒側之間保持恒定的間隙（其間隙值由工況及泵本身規格決定），螺桿外圓與襯套內圓面也保持恒定的間隙不變。兩根螺桿的傳動由同步齒輪完成。齒輪箱中有獨立的潤滑，與泵工作腔隔開。這種結構的優點大大拓寬了雙螺桿泵的使用范圍，即：除了輸送潤滑性良好的介質外，還可輸送大量的非潤滑性介質，各種粘度（高粘度可達 3*106mm/s ）的介質以及具有腐蝕性（酸、堿等性質），磨蝕性的液體。
雙螺桿泵由于其恒定間隙的存在以及型線上的特點，其屬于非密封型容積泵，因此除了輸送純液體外，還可輸送氣體和液體的混合物，即汽液混輸，這也是雙螺桿泵非常獨特的優點之一。 雙螺桿泵由于結構的獨特設計，可以自吸而無須專門的自吸裝置，而且由于軸向輸送軸流速度較小而具備很強的吸上能力即很小的 NPSHr 值。
雙螺桿泵還可干轉。由于運動部件在工作時互不接觸，因此短時的干轉不會破壞泵元件，這種特點給自動控制的流程提供了極大的方便，但干運轉時間受多種因素限制，一般很短。
另外雙螺桿泵在輸送過程中無剪切，無乳化作用，因此不會破壞分子鏈結構和工況流程中所形成的特定的流體性質，并且由于傳動依靠同步齒輪，泵運轉噪音低，振動小，工作平穩。
四、雙螺桿泵應用范圍
