水泵出現(xiàn)滲水的部位主要是兩個(gè)部分，一是水泵的軸承密封件，一般此處漏是從水泵的溢流孔流出，此時(shí)需要更換水泵；二是水泵的也發(fā)動(dòng)機(jī)結(jié)合部件的密封件，杭州電動(dòng)泵密封生產(chǎn)企業(yè)，這里可以單獨(dú)更換此零件（提醒大家要注意避免“小病大治”），杭州電動(dòng)泵密封生產(chǎn)企業(yè)。 </p> <p> 水泵滲漏的原因：由于水泵設(shè)計(jì)原因，杭州電動(dòng)泵密封生產(chǎn)企業(yè)，水泵軸承收到側(cè)面單邊力量過(guò)大，也就是皮帶輪側(cè)偏心力大，容易導(dǎo)致水泵軸承偏磨；加之大家平時(shí)急加速的和急收油等加速皮帶對(duì)水泵軸承的沖擊（這是從用的角度出發(fā)）；內(nèi)部缺水，水泵軸承得不到冷卻液的潤(rùn)滑，也會(huì)導(dǎo)致密封件損壞（這是從養(yǎng)的角度出發(fā)）；防凍液長(zhǎng)時(shí)間不更換，雜質(zhì)增加加速磨損（同樣也是養(yǎng)的問(wèn)題）；

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(zhǎng)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(guò)千萬(wàn)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(kāi)。</span> </p> <p> <span style="font-size:12px;"> 解決這些密封問(wèn)題的答案也許是采用非平衡式密封，對(duì)于某些服務(wù)來(lái)說(shuō)，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(wèn)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>

對(duì)連續(xù)運(yùn)轉(zhuǎn)的設(shè)備,介質(zhì)內(nèi)若含有較多的固體顆粒,此時(shí)選用“硬對(duì)硬”結(jié)構(gòu)較好, 在實(shí)際應(yīng)用中選了YG6- YG6, 一般連續(xù)運(yùn)轉(zhuǎn)壽命在800Oh以上; </p> <p> 對(duì)間歇性的運(yùn)轉(zhuǎn)設(shè)備,摩擦副選用碳化鎢或碳化硅對(duì)特種石墨。 </p> <p> 對(duì)金屬波紋管部分進(jìn)行適當(dāng)?shù)臒崽幚砟芟附訋?lái)的殘余應(yīng)力,以避免長(zhǎng)期運(yùn)行過(guò)程中產(chǎn)生疲勞破裂. </p> <p> 由于在低溫條件下,摩擦副端面的氣化對(duì)機(jī)械密封性能影響很大,除選取較適合的材料外,合理選取端面比壓,主要是波紋管的壓縮量,一般比通常使用中所給的壓縮量大15%～30%為宜。在機(jī)械密封元件靠近大氣側(cè)通入25℃左右的冷卻水,以改善摩擦副潤(rùn)滑環(huán)境。 </p></p><br /><p>文章來(lái)源地址:
