口環(huán)，也叫耐磨環(huán)。其主要作用是防止出口端介質(zhì)倒流回進(jìn)口端介質(zhì)也就是密封作用（因此有“密封環(huán)”這一名稱）；同時(shí)也起耐磨作用，避免葉輪和泵殼直接接觸損壞，有保護(hù)葉輪的作用（因此有“耐磨環(huán)”這一名稱）。</span> </p> <p> <span style="font-size:12px;">離心泵口環(huán)，一般水泵的級(jí)數(shù)與口環(huán)的數(shù)量是一樣的，也就是說一個(gè)5級(jí)的水泵，那么口環(huán)也就有5個(gè)，一個(gè)首口環(huán)，4個(gè)口環(huán)。</span> </p> <p> <span style="font-size:12px;">多級(jí)離心泵口環(huán)的作用是在葉輪與泵殼間形成狹窄、曲折的通道，來增加介質(zhì)的流動(dòng)阻力，達(dá)到減少介質(zhì)泄漏的目的。離心泵口環(huán)的設(shè)置還起到保護(hù)泵上主要零件不受磨損的作用(公眾號(hào):泵管家)，在口環(huán)磨損后，可以修復(fù)或更換新環(huán)、恢復(fù)正常裝配間隙，這樣既經(jīng)濟(jì)又便于檢修。</span> </p> <p> <span style="font-size:12px;">口環(huán)間隙大會(huì)將低泵的使用效率，經(jīng)過泵加壓的流體會(huì)過多的從泵出口區(qū)域沿葉輪與口環(huán)的間隙返回到進(jìn)口，從而降低了泵的使用效率，同時(shí)由于流量的加大，會(huì)使口環(huán)過早的被磨損。口環(huán)間隙過大，會(huì)導(dǎo)致泵的流量降低，嚴(yán)重時(shí)不上量。 </span> </p> <p> <span style="font-size:12px;">離心泵口環(huán)的完好性及它與葉輪問徑向間隙含，在拆卸泵時(shí)應(yīng)首先檢查。如離心泵口環(huán)已有溝槽等缺損或已破裂或間隙艿超過表5中所規(guī)定的數(shù)值時(shí)，應(yīng)更換新口環(huán)或?qū)⒃诃h(huán)補(bǔ)焊修復(fù)。</span> </p> <p> <br />

一般情況下，介質(zhì)的溫度超過120℃即認(rèn)為是高溫密封。此時(shí)機(jī)械密封存在的主要問題有：(1)由于摩擦副端面溫度升高，導(dǎo)致密封端面間液膜氣化，摩擦系數(shù)隨之增大，磨損加劇，溫升加大，密封環(huán)產(chǎn)生熱變形或熱裂而失效；(2)機(jī)械密封中的輔助密封圈材料一般為橡膠或聚四氟乙烯，由于長(zhǎng)時(shí)間在高溫環(huán)境中，容易老化和分解，造成密封失效；(3)高溫下機(jī)械密封的彈性元件易產(chǎn)生疲勞和蠕變，使密封失效；(4)高溫會(huì)加劇金屬材料的腐蝕，縮短機(jī)封的使用壽命。

排污泵采用獨(dú)特的單葉片或雙葉片葉輪結(jié)構(gòu)，**提高了污物通過能力，能有效的通過泵口徑的5倍纖維物質(zhì)與直徑為泵口徑約50%的固體顆粒。機(jī)械密封采用新型硬質(zhì)耐腐的碳化鎢材料，同時(shí)將密封改進(jìn)為雙端面密封，使其長(zhǎng)期處于油室內(nèi)運(yùn)行，可使泵安全連續(xù)運(yùn)行8000小時(shí)以上。整體結(jié)構(gòu)緊湊、體積小、噪聲小、節(jié)能效果優(yōu)良，檢修方便，無需建泵房，潛入水中即可工作，減少工程造價(jià)。

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。機(jī)械密封的工作溫度不能超過其規(guī)定值。常州計(jì)量泵密封市場(chǎng)批發(fā)價(jià)格</p><p
