4月16日微型水泵能在不加引水的情況下，可以吸水，就表示這個(gè)水泵有自吸的功能?？沙槿∷⒁后w(溶液)，適用于需要進(jìn)行液體轉(zhuǎn)移、提升、清洗、噴灑、沖洗、灌溉等等多種場(chǎng)合。水泵的抽水管內(nèi)是空氣的情況下，利用泵工作時(shí)形成的負(fù)壓（真空），在大氣壓的作用下將低于抽水口的水壓上來，再從水泵的排水端排出。這個(gè)過程前是不需要加“引水（引導(dǎo)用的水）”的。就是說具備這種自吸能力的微型水泵，就叫“微型自吸水泵”。簡稱：“微型吸泵”原理類似微型真空泵。 </p> <p> 微型水泵油脂粘度是發(fā)揮真空泵性能的重要因素之一，液體的粘度是液體流動(dòng)阻力，或者說是液體的內(nèi)摩擦力，因此粘度越大，各種運(yùn)動(dòng)部件所受的阻力就越大；但粘度太小，泵的密封性能變差，引起氣體泄漏，真空變劣。因此，各類微型水泵對(duì)潤滑油的選擇極為重要。 </p><div style="width:100%;text-align:

機(jī)械密封的平衡對(duì)接觸面的密封壓力有很大影響。這一密封壓力取決于密封本身的有效截面以及填料盒內(nèi)的壓力。 </p> <p> <span style="font-size:12px;"> 非平衡型密封的旋轉(zhuǎn)面相反一側(cè)的截面完全暴露于填料盒的壓力范圍之下，這種情況會(huì)使密封面之間產(chǎn)生很高的密封壓力，從而會(huì)使工作溫度提高，加快磨損速度。在高溫工作條件下或液體具有較大腐蝕性和磨擦性的情況下，會(huì)極大降低機(jī)械密封的使用壽命。</span> </p> <p> <span style="font-size:12px;"> 對(duì)機(jī)械密封加以平衡，可降低密封壓力，延長密封的使用壽命。一般采用帶有臺(tái)階的主軸和軸套，降低旋轉(zhuǎn)面的有效截面，就可達(dá)到上述目的。不過千萬別將凈密封壓力調(diào)節(jié)到接近零的水平，因?yàn)檫@樣做的結(jié)果可能會(huì)造成密封面之間的工作狀況不穩(wěn)定，并可能會(huì)因突然的變故而將密封吹開。</span> </p> <p> <span style="font-size:12px;"> 解決這些密封問題的答案也許是采用非平衡式密封，對(duì)于某些服務(wù)來說，也許采用非平衡式密封能達(dá)到更好的效果。例如，在某些應(yīng)用領(lǐng)域，與密封的使用壽命相比，也許更強(qiáng)調(diào)對(duì)液體泄漏造成的安全性問題。在這種情況下，對(duì)密封的選用也許可理解為更希望選擇具有較高的密封壓力。同樣，在選用較冷液體的密封時(shí)，操作溫度的增加也許是微不足道的。</span>
