不鏽鋼(gāng)單螺杆泵的結構與(yǔ)特點(diǎn)
發布(bù)時間(jiān)：2014-9-22 9:11:57 點(diǎn)擊(jī)次數：
    不鏽(xiù)鋼單螺杆(gǎn)泵(bèng)是(shì)一種單螺(luó)杆式(shì)輸運泵(bèng),它的主要(yào)工作部件是(shì)偏(piān)心螺旋(xuán)體的螺杆（稱轉(zhuǎn)子）和(hé)内表(biǎo)面呈(chéng)雙線螺旋面的(de)螺杆襯(chèn)套(tào)（稱定(dìng)子）。
    不(bú)鏽鋼單螺(luó)杆泵的工(gōng)作原(yuán)理是(shì)當電(diàn)動機(jī)帶動(dòng)泵軸(zhóu)轉動(dòng)時,螺杆一(yī)方面(miàn)繞本(běn)身(shēn)的軸線(xiàn)旋轉,另(lìng)一方面(miàn)它又沿襯套内(nèi)表面滾動,于是(shì)形成泵的密封(fēng)腔室。螺(luó)杆(gǎn)每轉一周,密封腔内的液體向前推(tuī)進一個螺距,随(suí)着螺杆的連續轉動(dòng),液體螺旋(xuán)形方式(shì)從一個(gè)密封腔壓向另(lìng)一個密封(fēng)腔,最(zuì)後擠(jǐ)出泵體。
    單(dān)螺杆泵是(shì)一種(zhǒng)新型(xíng)的輸送液(yè)體(tǐ)的(de)機械(xiè),具有(yǒu)結構(gòu)簡單、工作(zuò)安全可靠(kào)、使用(yòng)維修方便、出液(yè)連續均勻、壓力穩定等優點。一(yī)種利用螺(luó)杆(gǎn)的旋轉來(lái)吸排液(yè)體的泵(bèng)，它(tā)最适(shì)于吸(xī)排黏(nián)稠液體.    
    stainless steel single screw pump is a single-screw transport pump, its main working parts are eccentric screw (rotor) of helix and the inner surface is on the surface of the double spiral screw bushing (called stator).stainless steel working principle of single screw pump is when the motor drives the pump shaft rotation, screw around the axis of rotation itself on the one hand, on the other hand it along the bushing inside surface rolling, then form the pump seal chamber.screw each week, liquid sealed cavity forward a pitch, with continuous rotation of the screw, liquid spiral way from a sealed cavity pressure to the other a sealed cavity, finally out of the pump body.single screw pump is a new type of fluid conveying machinery, has a simple structure, safe and reliable work, convenient operation and maintenance, the fluid continuous uniform, stable pressure, etc.a use of the rotation of the screw to absorb liquid pump, it is most suitable for suction row of viscous liquid.single screw pump has the following advantages:
    單(dān)螺(luó)杆泵有(yǒu)以下(xià)優點：
    1)壓(yā)力(lì)和流(liú)量範圍寬(kuān)闊。壓(yā)力(lì)約在3.4-340千(qiān)克力(lì)/cm 2，流量可達18600cm3/分(fèn)； 　
    1) the wide range of pressure and flow.pressure about 3.4-340 kg/cm 2, flow rate of up to 18600 cubic cm/min;
    2)運(yùn)送液體的(de)種類和粘(zhān)度範(fàn)圍寬廣(guǎng)； 　　
    2) wide range of delivery and type of liquid viscosity;
    3)因(yīn)為泵(bèng)内的(de)回轉部件(jiàn)慣性(xìng)力(lì)較低，故(gù)可使用很(hěn)高的(de)轉速；  
    3) because the rotary inertia force component inside the pump is low, so it can be used in high speed;　　4)吸入(rù)性(xìng)能(néng)好，具有自(zì)吸能(néng)力； 　　
    4) inhalation can good, self-priming ability;
    4)流量均勻連(lián)續，振動(dòng)小(xiǎo)，噪音(yīn)低； 　　
    4) flow uniformly continuous, little vibration, low noise;
    5)與其(qí)它回轉(zhuǎn)泵相(xiàng)比，對進入(rù)的氣(qì)體和(hé)污物不太敏(mǐn)感； 　
    5) compared with other rotary pump, less sensitive to enter gas and dirt;　
    6)結構(gòu)堅實(shí)，安裝(zhuāng)保養(yǎng)容易(yì)。 　　
    單螺(luó)杆泵(bèng)和其(qí)它(tā)螺杆泵(bèng)一樣，當泵(bèng)的排(pái)出口完全封閉(bì)時，泵内的(de)壓力(lì)就會(huì)上升到使(shǐ)泵損壞或使電動機過載的危(wēi)險程度(dù)。所以，在泵的吸(xī)排(pái)口處(chù)，就必須設(shè)置安(ān)全閥。不鏽鋼單(dān)螺杆泵的(de)軸封，通常采用機械(xiè)軸封(fēng)，并(bìng)可根據工作(zuò)壓力的高(gāo)低采取(qǔ)不同(tóng)的(de)形式(shì)。
    6) solid structure, installation and maintenance easy.other single screw pump and screw pump, when the pump outlet is completely closed, the pressure inside the pump will rise to make pump damage or that the degree of danger of motor overload.so, in the pump suction paikou, you must set the relief valve.stainless steel single screw pump shaft seal, usually adopts mechanical shaft seal, and may take different forms according to the working pressure of discretion.
