但是以前提出的各種方法再實(shí)際應(yīng)用中由于種種因素的影響效果不夠理想。為了更好的提高機(jī)械密封的使用壽命，節(jié)資降耗，針對(duì)各種情況，建議應(yīng)把以下措施綜合起來(lái)采用:a)將金屬波紋升設(shè)計(jì)成旋轉(zhuǎn)型結(jié)構(gòu)，旋轉(zhuǎn)的波紋管機(jī)械密封有自清洗的離心作用，這可以減少波紋管**沉積和內(nèi)側(cè)結(jié)焦。b)對(duì)摩擦副組對(duì)材料，建議使用“硬對(duì)硬”結(jié)構(gòu)，一般采用碳化鎢對(duì)碳化鎢(其中選YG6-YG6)和碳化鎢對(duì)碳化硅。選用“硬對(duì)硬”結(jié)構(gòu)，必須注意以下幾個(gè)問(wèn)題:1)冷卻系統(tǒng)要保障，禁止冷卻水中斷，以防端而升高，潤(rùn)滑膜閃蒸而降低密封端面的潤(rùn)滑，加劇磨損;2)機(jī)械密封在安裝過(guò)程中，要給密封端而澆一些潤(rùn)滑油(機(jī)油或黃油均可)。以防止起泵時(shí)。密封端面由于缺乏潤(rùn)滑而造成的干摩擦;3)采用清潔的外沖洗是解決溶劑顆粒堆積的比較有效的方法之一，但這種方法浪費(fèi)較大，而且各種泵的介質(zhì)、溫度、壓力(一般要求沖洗液壓力比介質(zhì)側(cè)壓力高.12MPa)又各不相同，外沖洗系統(tǒng)結(jié)構(gòu)就更繁雜，加之外沖洗設(shè)施的投入以及維護(hù)費(fèi)用的消耗，有時(shí)會(huì)造成弊大一于利，尤其是一些中小型業(yè)。因此許多企業(yè)的封油系統(tǒng)棄之不用，或者就沒(méi)有設(shè)這套系統(tǒng)，針對(duì)這些情況，建議使用配用隔離介質(zhì)的多密封結(jié)構(gòu)，如油漿泵、回?zé)捰捅玫取?/p><p> 1．改進(jìn)密封結(jié)構(gòu)及正確選擇摩擦副材料。實(shí)踐證明，在靜環(huán)表面開(kāi)圓弧形凹槽可形成流體動(dòng)力密封，增加流體膜承載能力，改善端面潤(rùn)滑條件，有效延長(zhǎng)機(jī)封工作壽命。在端面配對(duì)方面，碳化鎢一M106K石墨組對(duì)（即動(dòng)、靜環(huán)材料）一般要優(yōu)于其他材料，因?yàn)槠錆?rùn)滑性好，摩擦系數(shù)低，導(dǎo)熱性也比較好。2．選擇合適的端面比壓。低溫密封由于端面潤(rùn)滑性差，容易發(fā)生氣化、結(jié)冰，所以在保證密封可靠的前提下，端面比壓可適當(dāng)減小。一般機(jī)械密封比壓值推薦為，對(duì)低溫密封可取其下限。對(duì)金屬波紋管機(jī)械密封，由于動(dòng)環(huán)沒(méi)有軸向摩擦，端面比壓甚至可以低于下限。3．工藝上采取相應(yīng)措施。如盡量減少介質(zhì)的含水量；保持密封腔壓力的相對(duì)穩(wěn)定；盡可能配備沖洗冷卻裝置；在設(shè)備啟動(dòng)前，對(duì)機(jī)封部位進(jìn)行適當(dāng)預(yù)熱等。三、高速下的機(jī)械密封當(dāng)轉(zhuǎn)速超過(guò)3000r/min或者摩擦副的線速度超過(guò)25m/s時(shí)，一般可視為高速密封。在高速條件下，摩擦端面由于線速度很大，摩擦產(chǎn)生的熱量也多，此時(shí)端面液膜不容易形成，磨損加劇。高速還容易引起旋轉(zhuǎn)環(huán)的振動(dòng)，并受到較大的離心力作用，不利于端面間液膜的形成和維持。所以在高速情況下，為了減小離心力和振動(dòng)的影響，應(yīng)盡量減少轉(zhuǎn)動(dòng)部件，采用彈簧靜止式結(jié)構(gòu)。安德里茲泵用機(jī)械密封。</p><div

經(jīng)常用作IS離心泵軸封。副葉輪密封往往在密封腔內(nèi)側(cè)配置若干固定導(dǎo)葉片，它們可以起穩(wěn)流與部分消除副葉輪平滑面的增壓作用，從而提高葉輪的密封能力。離心動(dòng)力密封的特點(diǎn)在于它沒(méi)有直接接觸的摩擦副，可接納較大的密封間隙，因此能密封含有固相雜質(zhì)的介質(zhì)，磨損小，壽命長(zhǎng)，設(shè)計(jì)合理可以做到零泄漏。但是克服壓差的能力低，功率消耗大，甚至可達(dá)泵有用功率的l/3。此外，由于它是一種動(dòng)力密封，所以一停車立即喪掉密封能力，為此必須輔以停車密封。（2）螺旋動(dòng)力密封螺旋動(dòng)力密封的工作原理相當(dāng)于一個(gè)螺桿容量泵，設(shè)軸上切出右螺旋（或在殼體上、在兩者都刻有螺旋槽），軸的旋轉(zhuǎn)標(biāo)的目的從右向左看為順時(shí)針標(biāo)的目的，則液體介質(zhì)與殼體的摩擦力為逆時(shí)針標(biāo)的目的，而摩擦力F在該右螺紋的螺旋線上的分力向右，故液體。介質(zhì)猶如螺母沿螺桿松退環(huán)境一樣，將液體推向右方。跟著容量的不斷縮小，壓頭逐步增高，這樣，建立起的密封壓力與被密封流體的壓力相平衡，從而阻止了泄漏。設(shè)計(jì)螺旋密封裝置時(shí)，對(duì)于螺旋的趕油標(biāo)的目的要出格注意，若把標(biāo)的目的弄錯(cuò)了，不單不能密封，相反，卻把液體趕向漏出標(biāo)的目的，使得泄漏量大為增加。顯然，螺旋密封亦是一種動(dòng)力密封。貴陽(yáng)11-LP-D-S32-D20/50-DE安德里茲泵用機(jī)械密封</p><p
