符合GB9439-88的要求，過流表面光潔無粘砂、尖角、冷隔、氣孔、砂眼等缺點(diǎn)。（4）主軸材質(zhì)選用3Cr13經(jīng)調(diào)質(zhì)處理，有效地、可靠地傳遞動(dòng)力。主軸與葉輪用鍵連接，以傳遞動(dòng)力。主軸與葉輪用葉輪螺母鎖緊并有止退墊片，淮安單級(jí)泵密封哪家比較好，可防止水泵倒轉(zhuǎn)，造成葉輪松脫。（5）密封環(huán)：材質(zhì)鑄造青銅，防止因銹蝕而與葉輪咬死。設(shè)有密封環(huán)可更大限度地減少內(nèi)部泄露，提高水泵的效率。（6）機(jī)械密封：采用兩套單端面非平衡型機(jī)械密封，淮安單級(jí)泵密封哪家比較好。油腔和電機(jī)室之間的上部密封單元由陶瓷，石墨組成；泵殼和油腔之間的下部密封單元由碳化硅，碳化硅組成，以防接觸介質(zhì)。

在新增的水泵中全部采用了機(jī)械密封，與原有水泵的盤根密封形成了鮮明的對(duì)比：（1）機(jī)械密封與盤根密封在密封性能上，機(jī)械密封要比盤根密封漏泄量小的多，*為盤根密封漏泄量的1%。（2）使用壽命長(zhǎng)，兩年以內(nèi)無需更換，以往盤根密封每60天左右就要進(jìn)行一次更換。（3）消耗功率較少同比盤根密封省電5%以上。（4）減少了軸或軸承的磨損。 </p> <p> 通過摸索對(duì)比先后將車間的兩臺(tái)循環(huán)水泵、兩臺(tái)射水泵、凝結(jié)水泵共6臺(tái)泵進(jìn)行了進(jìn)行密封改造。改造后均收到了良好的效果。 </p> <p> 循環(huán)水泵（20HBA）在未改為機(jī)械密封前，每年至少要更換4次油盤根，每次更換量在1公斤左右，市場(chǎng)價(jià)格30元.，由于盤根磨損所致3年左右需更換一根水泵軸及配套軸瓦，費(fèi)用在7000元左右，不計(jì)人工費(fèi)用每臺(tái)水泵每年消耗在2500元左右。而改為機(jī)械密封后費(fèi)用方面每臺(tái)泵的機(jī)械密封價(jià)格在600元左右，至少一個(gè)大修期在3年以上，由于摩擦阻力的降低使電耗每小時(shí)下降8度，全年節(jié)電在58000度，降低成本3萬元左右。因此機(jī)械密封于盤根密封相比優(yōu)勢(shì)十分明顯。

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 />
