為了使機械密封做到密封性能可靠，使用壽命長，對其零件的尺寸、配合、形位公差等均有相應的要求。關鍵尺寸一定要嚴格按公差要求加工，非關鍵尺寸在不影響密封性能和安裝尺寸的前提下，可適當降低要求，這對于降低成本、普及推廣機械密封技術均有好處。根據(jù)國內(nèi)技術標準規(guī)定的機械密封技術條件及制造水平，參考國外同類產(chǎn)品的加工尺寸及精度要求，對常用機械密封零件的公差配合及技術要求介紹如下。一、機械密封零件的公差與配合關于機械密封零件的公差與配合，以內(nèi)裝式泵用機械密封零件為例作介紹，其他結構類型機械密封的主要零件配合及公差均可參考，并根據(jù)情況做適當調(diào)整，機械密封零件的公差與配合如圖9-1所示。①安裝機械密封軸徑公差；②彈簧座內(nèi)徑與軸公差；③推環(huán)內(nèi)徑與軸的配合公差；④推環(huán)接觸密封圈處端面的內(nèi)徑偏差；⑤推環(huán)接觸密封圈處端面的外徑偏差；⑥傳動套內(nèi)徑公差；⑦動環(huán)安裝密封圈處內(nèi)徑公差；⑧動環(huán)內(nèi)徑與軸的配合公差；⑨傳動套傳動的動環(huán)外徑公差；⑩撐環(huán)內(nèi)徑公差；?撐環(huán)外徑公差；?鑲環(huán)結構配合公差（此公差*供參考，制造時應根據(jù)實際情況核算確定公差尺寸）；?靜環(huán)外徑與壓蓋（或殼體）的配合公差；?靜環(huán)內(nèi)徑偏差；?靜環(huán)尾部與靜環(huán)座。麗江襄樊五二五泵用機械密封件廠家。</p><div

七、目前應用的密封種類根據(jù)制造方法和材料的不同，目前應用的密封環(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構。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?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，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。銅仁凝結水泵泵用機械密封件廠家。南寧安德里茨泵用機械密封件廠</p><p

其主要原因是制造金屬波紋管的材料欠佳，大都用181型不銹鋼制造。這種材料耐腐蝕，但強度和彈性較差，特別是在高溫下，使用一段時間后出現(xiàn)“失彈”。國外大都用AM350制造，這是一種沉淀硬化不銹鋼，高溫下仍有足夠的強度和彈性，先彈的機會較少。但是，經(jīng)過長期使約后也暴露了一些缺陷，在波片的焊縫附近開裂。究其原因是在受壓狀態(tài)下。一軸向斷面上各處應力分布不均勻，有較嚴重的應力集中現(xiàn)象，從而降低了使用壽命?，F(xiàn)有的焊接金屬波紋管其斷面的內(nèi)外緣處（或稱波谷和波峰）、幾何形狀和尺寸是相同的，故也稱為“對稱型”波紋管。它具有上述缺陷，為克服此缺陷，出現(xiàn)了“非對稱型”波紋管。所謂非對稱型波紋管是波谷（內(nèi)緣處）和波峰（外緣處）購肉率半徑不同，波峰大于波谷。在介質(zhì)壓力作用下，迫使其向低壓側變形，工作時斷面形狀趨于對稱，應力趨于均勻（圖44）。同時由于采用了特殊結構的波紋管，焊縫長度縮短。據(jù)國外資料介紹一種13/4英寸的T15WTO型密封，焊縫總長度超過4000mm，而同樣尺寸的非對稱型波紋管密封，焊縫長度*87mm，使密封的可靠性提高，密封能力提高30%，波紋管的彈性提高了40%。非對稱型波紋管在國外已投放市場。南寧安德里茨泵用機械密封件廠</p></p><br
