泵用機(jī)械密封的安裝和使用機(jī)械密封大多用于各種類型的泵。機(jī)械密封是一種精度較高的密封裝置，對安裝和使用條件均有一定的要求。機(jī)械密封安裝使用的一般原則弄清設(shè)備的情況，要了解設(shè)備轉(zhuǎn)軸的轉(zhuǎn)速、軸徑；設(shè)備制造精度及密封腔尺寸，設(shè)備本身的使用壽命以及設(shè)備在生產(chǎn)工藝中的地位等要做均衡的考慮。估算介質(zhì)壓力。泵的密封腔壓力一般不是泵的出口壓力，而是低于泵的出口壓力。弄清密封介質(zhì)情況。要知道密封介質(zhì)的狀態(tài)，是氣態(tài)還是液態(tài)，介質(zhì)是否含顆粒及顆粒狀況；了解介質(zhì)的性質(zhì)，泰州離心泵密封規(guī)格型號、溫度，以便合理選型及采取必要的冷卻、沖洗、潤滑措施。機(jī)械密封安裝使用的技術(shù)要求安裝機(jī)械密封部位的軸或軸套的徑向跳動公差：Ф10~50mmФ50~120mm,。軸或軸套的表面粗糙度應(yīng)符合技術(shù)要求，外徑尺寸公差為h6。傳動軸的軸向竄動量不超過。密封腔體端面對軸表面的跳動公差：軸或軸套外徑端面跳動公差:Ф10~50mm，Ф50~120mm,軸或軸套的端面及密封腔體的端面要有倒角。軸徑≤Φ30mm時為3×10°，泰州離心泵密封規(guī)格型號，軸徑＞Φ30mm時為4×10°。當(dāng)輸送介質(zhì)溫度偏高、過低或含有雜質(zhì)顆粒、易燃、易爆、時，應(yīng)采取相應(yīng)的阻封、沖洗，泰州離心泵密封規(guī)格型號、冷卻、過濾等措施。

機(jī)械密封按工作條件和介質(zhì)性質(zhì)的不同，有耐高溫、耐低溫機(jī)械密封，耐高壓、耐腐蝕機(jī)械密封，耐顆粒介質(zhì)機(jī)械密封和適應(yīng)易汽化的輕質(zhì)烴介質(zhì)的機(jī)械密封等，應(yīng)根據(jù)不同的用處選取不同結(jié)構(gòu)型式和材料的機(jī)械密封。 </p> <p> 選型的主要參數(shù)有：密封腔體壓力（MPa）、流體溫度（℃）、工作速度（m/s）、流體的特性以及安裝密封的有效空間等。 </p> <p> <p> 根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。 </p> <p> 根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動壓式或非接觸型。 </p> <p> 根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及正確選擇潤滑、沖洗、保溫、冷卻等機(jī)械密封循環(huán)保護(hù)系統(tǒng)等。 </p> <p> 根據(jù)安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內(nèi)裝式或外裝式。 </p> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="泰州離心泵密封規(guī)格型號" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247266600576172/7557626.jpg"></div><p> 低溫輕烴泵用機(jī)械密封 </p> <p> 多彈簧機(jī)械密封采用靜止結(jié)構(gòu)。 </p> <p> 采取增加非補(bǔ)償環(huán)尾部長度和采用副后蓋結(jié)構(gòu)等措施，增加輕烴泵機(jī)械密封的抗抽空能力。 </p> <p> 采用靜環(huán)背冷措施。 </p> <p> 對介質(zhì)易汽化的輕烴泵軸封我們增設(shè)背部冷卻,在軸封正常操作時,可對端面溫度進(jìn)行調(diào)節(jié),使相變半徑靠近內(nèi)徑,增大液膜比例。在泵抽空時,由于端面溫度降低,使閃蒸壓力降低,對防止端面分離有積極作用。 </p> <p> 摩擦副材料的選取。 </p> <p> 對摩擦副材料的選取我們采用“SiC-C”結(jié)構(gòu)。輔助密封材料選擇耐低溫的硅橡膠材料。 </p> <p> 采用自沖洗措施。 </p> <p> 通過沖洗來提高密封腔壓力以防止抽空造成的密封干摩擦。自沖洗措施不僅可保證密封腔內(nèi)有較高的介質(zhì)壓力,避免介質(zhì)在密封腔內(nèi)汽化或氣體積聚,而且還可把摩擦副產(chǎn)生的摩擦熱及時帶走,有效控制密封端面溫升,增大液相面積,改善摩擦狀態(tài)。 </p></p><br /><p>文章來源地址:
