硬環(huán)的材質(zhì)種類很多（見“27”）。只有在特殊情況下，如介質(zhì)中含有固體顆粒、有結(jié)晶析出或高粘度流體中才選用硬對硬的配對。當(dāng)選用一軟一硬的配對時硬環(huán)端面的寬度比軟環(huán)寬，在硬對硬的材質(zhì)中可不受此限制。為減少泄漏量和機械雜質(zhì)進入密封端面的可能性，盡量采用內(nèi)裝內(nèi)流式密封結(jié)構(gòu)S選擇導(dǎo)熱性良好的材料做動環(huán)，以散出較多的熱量，降低密封端面的溫度。為保證密封環(huán)的整體強度和剛度，環(huán)的壁厚不可太薄。對于導(dǎo)熱性良好的材料，增加環(huán)厚有利散熱；對于導(dǎo)熱性欠佳的材料厚度可小些。對于所受壓力較高的密封環(huán)，要從力學(xué)角度另行設(shè)計，必要時采取加固措施。環(huán)的形狀要軸對稱，以減少其不對稱的機械變形和熱變形。動環(huán)做補償環(huán)時，例如國產(chǎn)104和B104型密封（圖13、圖14），動環(huán)和軸（軸套）的（直徑）間隙為0．40～0．60mm，以防止動環(huán)在工作中卡住而失去補償能力；靜環(huán)內(nèi)徑要比軸（軸套）大l～2mm，湘潭204b釜用機械密封，避免兩者摩擦。密封端面的寬度是個重要參數(shù)，要綜合考慮。三、密封端面的寬度要考慮的因素密封端面的寬度一般是首先決定軟面的寬度，硬面寬度自不待說。泄漏量與端面寬度關(guān)系不大。但是，從產(chǎn)生的摩擦熱量來說窄一些較好，湘潭204b釜用機械密封，產(chǎn)生的熱量較少，湘潭204b釜用機械密封，溫度梯度小，熱變形也小。湘潭212釜用機械密封件。湘潭204b釜用機械密封</p><div

還要求在不拆除笨重的傳動機構(gòu)情況下，也能夠進行機械密封的拆卸和重新安裝;3.結(jié)構(gòu)上具有小尺寸的短軸和低的高度，帶安裝臂.聚丙烯裝置第3號、第4號反應(yīng)釜及粉末塔攪拌器都采用底裝式密封.圖10-4為Φ260底裝式機械密封的結(jié)構(gòu)圖.為了防止產(chǎn)品進人密封腔，在連接攪拌槳的法蘭下部有一鍋底形密封罩34，還有兩道襯套35、36及推力板33使大的顆粒被離心力拋出，小的顆粒也難于進人密封腔，對于接觸物料的上部(密封罩下面)密封，有的采用摩擦副密封;有的采用唇密封(軸向與橫向相結(jié)合的唇封);有的采用襯套密封(如圖10-4所示).密封罩表面、軸的上部、連接法蘭表面都應(yīng)研磨、拋光，以免物料粘結(jié)在表面上.四、停車密封裝置當(dāng)釜用密封有缺陷而需要帶壓更換機械密封時，可采用停車密封裝置(圖10-5)。這種裝置只要在停車時在軸封處通人外部壓力p，即可使軸密封，但這時軸就不能再轉(zhuǎn)動。它特別適用于無菌、發(fā)酵操作等容器的密封，但不適用于產(chǎn)品易凝固和變稠的場合。</p><p> 七、目前應(yīng)用的密封種類根據(jù)制造方法和材料的不同，目前應(yīng)用的密封環(huán)有整體式密封環(huán)（用同一種材料制造）、組合式密封環(huán)、表面堆焊硬質(zhì)合金和噴涂陶瓷等多種結(jié)構(gòu)。整體式密封環(huán)種類：這種密封環(huán)因用同一種材料制成，材料的性能在密封環(huán)的各個部位均勻一致，沒有組合式密封環(huán)泄漏和分離的缺陷，也沒有電化學(xué)腐蝕的可能。制造軟環(huán)大都用石墨，制造硬環(huán)時可用各種合金鋼，如軸承鋼（GCr9）、高速鋼（W18CrV）及其他合金鋼（如40Cr、3Cr13等），也有的用合金鑄鐵（如硅、鉻和鎳鑄鐵）。采用這些材料時，都要輔之以適當(dāng)?shù)臒崽幚砉に?，以提高其硬度和耐磨性。這類材料價格較低，如果使用恰當(dāng)，也有較長的壽命。為了進一步提高硬度和延長使用壽命，可采用硬質(zhì)合金制造。常用的硬質(zhì)合金為鉆基碳化鎢，性能較好，但價格高。鋼結(jié)硬質(zhì)合金的價格較低。為了提高在腐蝕介質(zhì)中的耐蝕性，有鎳基碳化鎢，而哈氏合金有更高的耐蝕性，但價格昂貴。此外，還有用碳化硅及其他陶瓷材料制造的密封環(huán)。出現(xiàn)組合式由封環(huán)的原因碳化鎢等材料有優(yōu)良的性能，但是價格高，加工困難，限制了它的使用。為解決這個矛盾，出現(xiàn)了組合式密封環(huán)。密封端面采用硬質(zhì)合金，密封環(huán)的基體。張家口FMY212釜用機械密封廠家。</p><div

當(dāng)產(chǎn)生抽空（汽蝕）時，靜環(huán)能離位，從而損壞密封。2）固定型靜環(huán)。圖21所示為幾種固定型靜環(huán)，這種靜環(huán)由于浮動性差，安裝時尤其要注意密封端面和軸心線的垂直度。其優(yōu)點是泵抽空時靜環(huán)不至于離位，較為可靠。3）粘結(jié)型靜環(huán)。上兩種靜環(huán)安裝在壓蓋中時都設(shè)有密封圈，而粘結(jié)型靜環(huán)則取消了密封圈，靜環(huán)與壓蓋之間的密封和防轉(zhuǎn)，用粘結(jié)劑實現(xiàn)。由于采用了粘結(jié)劑，使用溫度和介質(zhì)受到了粘結(jié)劑性能的限制，盡管如此，仍在很多場合得到應(yīng)用。集裝式密封的軸套的傳動普通機械密封的軸套都是事先安裝和固定在軸上后再安裝機械密封，而集裝式密封則不同，它是將密封軸套和壓蓋預(yù)先裝在軸套上，再整體向軸上安裝，于是存在一個軸套如何固定在軸上，并傳遞扭矩的問題，同時還要解決軸套和軸之間的泄漏問題。圖42a表示了一種傳動方式。螺釘安裝在零件A上，在軸套的對應(yīng)部位開有圓孔，將螺釘通過軸套的圓孔，并旋緊在軸上，即可實現(xiàn)軸套和軸的傳動。軸套和軸的密封，靠O形圈來完成。這種傳動方式比較簡單。圖42b是另一種傳動方式。它用圓螺母A壓緊軸和軸套之間的填料（四氟制成），靠填料與軸的摩擦力來傳動，同時也起到了密封圈的作用。太原212釜用機械密封廠家。湘潭204b釜用機械密封</p><p

不僅在開啟力和閉合力之間有嚴格比率，而且要求整個密封結(jié)構(gòu)經(jīng)得住高壓而不變形，此外，還要維持穩(wěn)定的液膜以保證密封性能.一、高壓機械密封的要求1.增大密封零件截面對轉(zhuǎn)動零件的截面要加大，靜環(huán)也相應(yīng)有較大的截面，不要在靜環(huán)外徑上有臺階或開槽.但要注意，隨著密封面寬度b的增加，熱變形和磨損也隨之增加，同樣要增加壓蓋的厚度以防變形和能承受壓力.使用重載荷彈簧，使用較大直徑的銷子以適應(yīng)較大的啟動扭矩.2.提高密封零件的加工精度(1)壓蓋底部裝靜環(huán)的幢孔面要保證高的平直度，因為在高壓下，任何表面上的高出點會傳給靜環(huán)而引起泄漏;(2)提高密封面內(nèi)外徑和寬度的加工精度，因為在高壓時，，密封內(nèi)外徑和寬度的精度對比壓的變化有明顯的影響.密封端面研磨、.拋光后的粗糙度為(▽12~▽13)，平直度必須限制在1個光帶以內(nèi).此外，摩擦端面的垂直度和軸的精度也要相應(yīng)提高.注意在高壓下因不同介質(zhì)所造成的沖刷腐蝕和磨損，圖10-12(a),(b)表示不同摩擦副材料在不同的轉(zhuǎn)速下介質(zhì)為烴和水及水溶液時壓力與密封尺寸的關(guān)系.5采用流體動壓式機械密封流體動壓式(也稱流體動力式，熱流體動壓式)機械密封是考慮在高壓和摩擦熱的情況下。湘潭204b釜用機械密封</p><p
