雙螺桿泵的結(jié)構(gòu)特點(diǎn)
Structure characteristics of double screw pump
雙螺桿泵是外嚙合的螺桿泵，它利用相互嚙合，互不接觸的兩根螺桿來(lái)抽送液體。
Twin screw pump, screw pump meshing, it uses mesh with each other, do not touch the two screws for pumping liquid.
雙螺桿泵作為一種容積式泵，泵內(nèi)吸入室應(yīng)與排出室嚴(yán)密地隔開(kāi)。因此，泵體與螺桿外圓表面及螺桿與螺桿間隙應(yīng)盡可能小些。同時(shí)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。
Twin - screw pump as a positive displacement pump, pump inhalation chamber should be strictly separated from rooms. Therefore, the pump body and the screw and screw and screw cylindrical surface gap should be as small as possible. Body, screw and screw and screw with each other form a sealed cavity pump room, to ensure airtight,otherwise there may be liquid from the gap in the back to go back.
雙螺桿泵可分為內(nèi)置軸承和外置軸承兩種形式。在內(nèi)置軸承的結(jié)構(gòu)型式中軸承由輸送物進(jìn)行潤(rùn)滑。外置軸承結(jié)構(gòu)的雙螺桿泵工作腔同軸承是分開(kāi)的。由于這種泵的結(jié)構(gòu)和螺桿間存在的側(cè)間隙，它可以輸送非潤(rùn)滑性介質(zhì)。此外，調(diào)整同步齒輪使得螺桿不接觸，同時(shí)將輸出扭矩的一半傳給從動(dòng)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(shù)泵輸送元件本身都是雙吸對(duì)稱布置，可消除軸向力，也有很大的吸高。
Double screw pump can be divided into internal and external bearing bearing two forms. Bearing in the built bearing structure of lubricating material from the conveyor. Double screw pump working chamber is separated from the external bearing structure with bearing. Because of the existence of this structure and the screw pumpbetween the side gap, it can transport non lubricating medium. In addition, the adjustment screw is not synchronized gear makes contact, while half of the output torque to the driven screw. As with all screw pump, the external bearing double screw pump with self absorption capacity, but the majority of pump components are themselves symmetrical arrangement of double suction, which can eliminate the axial force, but also has a lot of smoke high.
泵的這些特性使它在油田化工和船舶工業(yè)中得到了廣泛的應(yīng)用。外置軸承式雙螺桿泵可根據(jù)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(dá)250ºC。泵具有不同方式的加熱結(jié)構(gòu)，理論流量可達(dá)2000立方米/小時(shí)。
These characteristics make it pumps have been widely used in the oil chemical industry and shipbuilding industry.External bearing double screw pump can be adopted respectively according to various use of ordinary cast iron,stainless steel etc. different materials manufacturing. The delivery temperature of up to 250 º C. Pump with different ways of heating the structure, the theoretical capacity of 2000 cubic meters / hour.
雙螺桿泵的特點(diǎn)：
The characteristics of double screw pump:
無(wú)攪拌、無(wú)脈動(dòng)、平穩(wěn)的輸送各種介質(zhì)，由于泵體結(jié)構(gòu)保證泵的工作元件內(nèi)始終存有泵送液體作為密封液體，所有的泵有很強(qiáng)的自吸能力，且能汽液混輸。
Various medium conveying no mixing, no pulsation, smooth, because the pump body structure to ensure that the work of components within the pump is always there pumping liquid as sealing liquid, all the pumps are self-priming capability is very strong, and can the vapor-liquid mixed transportation.
泵的特殊設(shè)計(jì)保證了泵有高的吸入性能即很小的NPSHr值。
Special design of pump to ensure that the pump has high suction performance is very small values of NPSHr.
采用獨(dú)立潤(rùn)滑的外置軸承，允許輸送各種非潤(rùn)滑性介質(zhì)。
Using an independent external lubricated bearings, allowing delivery of various non lubricating medium.
臥式、立式、帶加熱套等各種結(jié)構(gòu)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(zhì)，選用正確的材質(zhì)，甚至可以輸送許多腐蝕性介質(zhì)。
Horizontal, vertical, with heating units and other structural type is complete, containing no solid particles of low or high viscosity media can transport all kinds of clean, choosing the right material, or even much of corrosive media delivery.
2.雙螺桿泵的用途
Use 2 double screw pump
由雙螺桿泵的原理知道，對(duì)于外置軸承的雙螺桿泵，通過(guò)軸承定位，兩根螺桿在襯套中互不接觸，齒側(cè)之間保持恒定的間隙（其間隙值由工況及泵本身規(guī)格決定），螺桿外圓與襯套內(nèi)圓面也保持恒定的間隙不變。兩根螺桿的傳動(dòng)由同步齒輪完成。齒輪箱中有獨(dú)立的潤(rùn)滑，與泵工作腔隔開(kāi)。這種結(jié)構(gòu)的優(yōu)點(diǎn)大大拓寬了雙螺桿泵的使用范圍，即：除了輸送潤(rùn)滑性良好的介質(zhì)外，還可輸送大量的非潤(rùn)滑性介質(zhì)，各種粘度（zui高粘度可達(dá)3*106mm/s）的介質(zhì)以及具有腐蝕性（酸、堿等性質(zhì)），磨蝕性的液體。
Know the principle of double screw pump, for the external bearing twin-screw pump, the bearing positioning, two screws in the Bush is not in contact with each other, tooth gap between the constant （the gap value determined by the working condition and the pump itself specifications）, screw cylindrical bushing with a round face and also to maintain a constant gap. Transmission by the two screw gears achieve synchronization. Gear box has a separate lubrication, with the pump working chamber separated. The utility model has the advantages of greatly broadens the scope of use, double screw pump: in addition to the conveying medium good lubrication, but also transport non lubricating medium large, various viscosity （peak viscosity up to 3*106mm/s） and corrosive medium（acid, alkali and other properties）, corrosive liquid.
雙螺桿泵由于其恒定間隙的存在以及型線上的特點(diǎn)，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*的優(yōu)點(diǎn)之一。
Double screw pump because of its constant gap and the characteristics of line, which belongs to the non sealpumps, so apart from pure liquid carrier, but also the transmission of gas and liquid mixtures, namely the vapor-liquid mixed transportation, which is also one of the advantages of very unique double screw pump.
雙螺桿泵由于結(jié)構(gòu)的*設(shè)計(jì)，可以自吸而無(wú)須專門(mén)的自吸裝置，而且由于軸向輸送軸流速度較小而具備很強(qiáng)的吸上能力即很小的NPSHr值。
Double screw pump because of the unique design of the structure, can be self absorption without specific self-priming device, but also because of the axial axial transmission speed of smaller and have a very strong absorption ability is very small values of NPSHr.
雙螺桿泵還可干轉(zhuǎn)。由于運(yùn)動(dòng)部件在工作時(shí)互不接觸，因此短時(shí)的干轉(zhuǎn)不會(huì)破壞泵元件，這種特點(diǎn)給自動(dòng)控制的流程提供了*的方便，但干運(yùn)轉(zhuǎn)時(shí)間受多種因素限制，一般很短。
Double screw pump can also be dry. Because of moving parts at work do not contact each other, so do short-term to not damage the pump components, this feature provides great convenience for the automatic control of theprocess, but the dry running time by a variety of constraints, are generally short.
另外雙螺桿泵在輸送過(guò)程中無(wú)剪切，無(wú)乳化作用，因此不會(huì)破壞分子鏈結(jié)構(gòu)和工況流程中所形成的特定的流體性質(zhì)，并且由于傳動(dòng)依靠同步齒輪，泵運(yùn)轉(zhuǎn)噪音低，振動(dòng)小，工作平穩(wěn)。
The double screw pump in the course of transmission without shear, non emulsifying effect, it will not destroy thespecific fluid properties the molecular chain structure and working process, and because relying on synchronous transmission gear pump operation, low noise, small vibration, stable work.
