原來平口環(huán)結(jié)構(gòu)改造為迷宮油封,既能有效阻止介質(zhì)中的硬顆粒進(jìn)入口環(huán)摩擦副對配合面進(jìn)行腐蝕,增加泄漏阻力提高泵的使用性能,也能防止口環(huán)配合面咬合抱死。具體來講:相對于平口環(huán)結(jié)構(gòu),在與主軸保持相同的配合間隙下,迷宮口環(huán)由于在旋轉(zhuǎn)軸周圍依次排列著許多環(huán)形密封齒,介質(zhì)在迷宮中流動時,具有更大的摩阻效應(yīng),使得流速更慢,流量更少,因此泵的泄漏損失更少,效率更高。將多級泵的口環(huán)設(shè)計成迷宮口環(huán)后,因葉輪口環(huán)與泵體口環(huán)之間的接觸面積變小,且迷宮齒之間有一定的空間,因此介質(zhì)的硬質(zhì)顆粒進(jìn)入口環(huán)后能夠在迷宮齒之間的空間停留,減小了轉(zhuǎn)子與泵體口環(huán)咬合抱死的概率。由于加工迷宮齒,需將原泵體口環(huán)的分半形式改造為整體形式，贛州格蘭富機(jī)械密封LF60123-AA6L6J,以便保證加工精度，贛州格蘭富機(jī)械密封LF60123-AA6L6J,改造后雖拆裝口環(huán)時需要逐級拆卸葉輪，贛州格蘭富機(jī)械密封LF60123-AA6L6J,拆除工作量增加,但是整體口環(huán)結(jié)構(gòu)可增強(qiáng)摩擦副配合的準(zhǔn)確性與加工精度,使泵的運(yùn)行更加穩(wěn)定可靠。臨城格蘭富機(jī)械密封件。贛州格蘭富機(jī)械密封LF60123-AA6L6J</p><div

軸與輔助密封的過盈量越來越大,動環(huán)與軸的摩擦力也會越來越大,在高溫高壓多級泵的運(yùn)行過程中動靜環(huán)磨損卻得不到位移補(bǔ)償,解決這種現(xiàn)象的辦法是:定期將高溫高壓多級泵切換運(yùn)行對機(jī)封進(jìn)行檢查和維護(hù),回裝時一定注意軸向竄量要小于。高溫高壓多級離心泵在運(yùn)行的過程中,很有可能會出現(xiàn)泵軸的周期性振動。這種現(xiàn)象會極大的影響高溫高壓多級泵機(jī)械密封的使用壽命,解決的辦法是:參照國家標(biāo)準(zhǔn)進(jìn)行檢維修,避免這種現(xiàn)象造成的機(jī)械密封失效。介質(zhì)不干凈,如果介質(zhì)中顆粒較大,會造成摩擦副的泄漏,要及時清理泵入口的過濾器。介質(zhì)腐蝕性較大,如果密封圈被介質(zhì)腐蝕造成泄漏,就要考慮提高材質(zhì)的等級了2.運(yùn)行環(huán)境惡劣對于一些運(yùn)行環(huán)境惡劣的離心泵來說,機(jī)械密封難以滿足工作介質(zhì)要求在運(yùn)行了一段時間以后就會發(fā)生機(jī)械密封泄漏的情況。彈性元件損壞引起泄漏。對于一些工作介質(zhì)易結(jié)晶或者含雜質(zhì)較多的離心泵來說,在將其解體檢修時,會發(fā)現(xiàn)其所用機(jī)械密封的彈性元件被結(jié)晶物或雜質(zhì)垢結(jié)堵塞,從而使彈性元件失去彈性,失彈的彈性元件無法給予動環(huán)應(yīng)有的軸向補(bǔ)償,從而導(dǎo)致機(jī)械密封出現(xiàn)泄漏的情況第二,輔助密封圈損壞引起泄漏。若工作介質(zhì)溫度過高,或者工作介質(zhì)中含有弱酸、弱堿等腐蝕性物質(zhì)。</p><p>
