螺杆泵大家族


螺杆泵的家族虽然称不上庞大,但是按照螺杆的标准,它也可以分为不同的类型。本文着重介绍最为常用的单螺杆泵、双螺杆泵以及三螺杆泵。



单螺杆泵

与其他泵相比,单螺杆泵有着自己独特的优势

双螺杆泵



DANCONGJIEGOUSHANGERYAN,SHUANGLUOGANBENGSHIWAINIEHEDELUOGANBENG。TALIYONGXIANGHUNIEHE,HUBUJIECHUDELIANGGENLUOGANLAICHOUSONGYETI。


在结构型式众博棋牌上双螺杆泵也很齐全,有卧式、立式、带加热套等各种类型,可以输送有颗粒的低粘度或高粘度介质,根据颗粒大小调节螺杆间距,选用正确的材质,甚至可以输送许多腐蚀性介质。


特点:双螺杆泵作为一种容积式泵,泵内吸入室应与排出室严密地隔开。这就要求泵体与螺杆外圆表面及螺杆与螺杆间隙应尽可能小些。同时螺杆与泵体、螺杆与螺杆间又相互形成密封腔,保证密闭,否则就可能有液体从间隙中倒流回去。


众博棋牌 SHUANGLUOGANBENGDUTEDEJIEGOUSHITAKEYISHIXIANWUJIAOBAN、WUMAIDONG、PINGWENDESHUSONGGEZHONGJIEZHI;YOUYUBENGTIJIEGOUBAOZHENGBENGDEGONGZUOYUANJIANNEISHIZHONGCUNYOUBENGSONGYETIZUOWEIMIFENGYETI,YINCISHUANGLUOGANBENGYOUHENQIANGDEZIXINENGLI,QIENENGQIYEHUNSHU。SHUANGLUOGANBENGDETESHUSHEJIHAIBAOZHENGLEBENGYOUGAODEXIRUXINGNENGJIHENXIAODENPSHrZHI。


双螺杆泵又可分为内置轴承和外置轴承两种形式。

外置轴承双螺杆泵特点:这种泵的结构和螺杆间存在侧间隙,独立润滑的外置轴承允许其输送各种非润滑性介质。此外,调整同步齿轮使得螺杆不接触,同时将输出扭矩的一半传给从动螺杆。

另外双螺杆泵由于其恒定间隙的存在以及型线上的特点,其属于非密封型容积泵,因此除了输送纯液体外,还可输送气体和液体的混合物,即汽液混输,这也是双螺杆泵非常独特的优点之一;



双螺杆泵还可干转:由于运动部件在工作时互不接触,因此短时的干转不会破坏泵元件,这种特点给自动控制的流程提供了极大的方便,但干运转时间受多种因素限制,一般很短。


另外双螺杆泵在输送过程中无剪切,无乳化作用,因此不会破坏分子链结构和工况流程中所形成的特定的流体性质,并且由于传动依靠同步齿轮,泵运转噪音低,振动小,工作平稳。


应用:外置轴承式双螺杆泵的种种特性使它在油田化工和船舶工业中得到了广泛的应用。它还可根据各种使用情况分别采用普通铸铁、不锈钢等不同材料制造;输送温度可达250℃;而且具有不同方式的加热结构,理论流量可达2000立方米/小时。



三螺杆泵



众博棋牌 SANLUOGANBENGSHIZHUANZISHIRONGJIBENG,TASHILIYONGLUOGANNIEHEYUANLI,YIKAOXUANZHUANDELUOGANZAIBENGTAONEIXIANGHUNIEHE。


原理:众博棋牌它主要是由固定在泵体中的衬套(泵缸)以及安插在泵缸中的主动螺杆和与其啮合的两根从动螺杆所组成。三根互相啮合的螺杆,在泵缸内按每个导程形成为一个密封腔,造成吸排口之间的密封。

由于两从动螺杆与主动螺杆左右对称啮合,三螺杆泵作用在主动螺杆上的径向力完全平衡,主动螺杆不承受弯曲负荷。从动螺杆所受径向力沿其整个长度都由泵缸衬套来支承,不需要在外端另设轴承,基本上也不承受弯曲负荷。

三螺杆泵和其它容积泵一样,当泵的排出口完全封闭时,泵内的压力就会上升到使泵损坏或使电动机过载的危险程度。所以,在泵的吸排口处,就必须设置安全阀众博棋牌。轴封通常采用机械轴封,并可根据工作压力高低采取不同的形式。


特点:三螺杆泵显著的特点是结构简单、压力脉动小、流量稳定、工作平稳可靠、允许高转速、噪音低、效率高、寿命长,有自吸能力。

应用:目前,三螺杆泵广泛应用于石油、化纤、冶金、机械、电力、机床、船舶、玻璃、公路等各行各业。三螺杆泵适用于输送燃料油、润滑油、液压油、原油、沥青及其他类似油的润滑性液体。三螺杆泵在工业领域中作润滑泵,在液压系统中作液压泵,在燃油系统中作输送及增压泵;在输油系统中作输送及加油泵。
