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3000r/min或者摩擦副的線速度超過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)。煙臺(tái)離心泵用機(jī)械密封山西飛力泵用機(jī)械密封型號(hào)。</p><div

機(jī)械密封的作用:一、提高機(jī)器效率、降低能耗。1、減少機(jī)器的內(nèi)漏、外漏和穿漏，提高機(jī)器容積效率。例如，大慶煉油廠將焦化5FDJ5×2離心泵的葉輪口環(huán)改為機(jī)械密封，使泵效率提高。2、減少摩擦損失，提高機(jī)器的機(jī)械效率。例如，將雙端面密封改為單端面密封、非平衡型改為平衡型、雙支承減底泵封閉一端(所謂砍頭泵)減少密封都能減少摩擦損失，提高機(jī)械效率。3、改變密封方式，提高機(jī)器或機(jī)組的效率。例如，將屏蔽泵改用機(jī)械密封泵，使電動(dòng)機(jī)效率提高;采用磁力傳動(dòng)泵，提高機(jī)器效率。4、改變輔助系統(tǒng)，減少能耗，提高機(jī)組效率。例如，熱油泵自沖洗改為小葉輪循環(huán)沖洗;雙端面密封改為單端面密封，節(jié)省封油輔助系統(tǒng)的能耗。二、節(jié)約原材料。例如，工藝流體回收，減少或消除動(dòng)力蒸汽和工藝流體的損耗，減少封油損耗等。三、提高機(jī)器可靠性。例如，軸封的漏損和壽命決定軸封和機(jī)器的可靠性。四、安全和環(huán)境保護(hù)。根據(jù)日本某廠調(diào)查報(bào)告，在發(fā)生的786件事故中有32件是泄漏造成的(占42%)。此外工藝流體泄漏還會(huì)造成環(huán)境污染，包括對(duì)大氣污染、水污染和車間環(huán)境污染。機(jī)械密封的意義:一、密封技術(shù)雖然不是領(lǐng)先性技術(shù)，但卻是決定性技術(shù)。例如，美國(guó)挑戰(zhàn)號(hào)航天飛機(jī)由于密封事故而墜落。綿陽(yáng)循環(huán)泵用機(jī)械密封泄露。煙臺(tái)離心泵用機(jī)械密封</p><p
