磨損較均勻；從受力角度考慮過窄不利，破壞和變形的可能性增加了＞俐，密封端面的直徑又是載荷系數(shù)的函數(shù)。因此，密封端面的寬度應(yīng)綜合考慮。一般地講，對普通介質(zhì)密封端面隨直徑的增大而加寬。對于輕烴類介質(zhì)，端面寬度比在普通介質(zhì)中寬一些：而高速機械密封，端面寬度相對地窄一些，否則發(fā)熱量太大，不能正常運轉(zhuǎn)，一般在3mm左右。環(huán)直徑（mm、環(huán)寬（mm）－20～602～460～1004～6100～2005—7四、密封環(huán)的技術(shù)要求：1）密封端面的平面度不大于0．0009mm（即三個單色光干涉帶）；硬質(zhì)材料密封端面粗糙度Ra值不大于0．2μm（相當(dāng)于Δ10）；軟質(zhì)材料密封端面粗糙度Ra值不大于0．4μm(相當(dāng)于Δ9)，表面不應(yīng)有裂紋、劃傷、氣孔和疏松等影響使用性能的缺陷。2）密封環(huán)的密封端面與輔助密封圈接觸的端面平行度按GBll84－80的7級精度規(guī)定。3）密封環(huán)端面與安裝輔助密封圈的內(nèi)（或外）圓表面的垂直度應(yīng)按GBll84－80的7級精度的規(guī)定。4）密封環(huán)與輔助密封圈接觸部位的表面粗糙度凡值不大于3．2μm；外圓或內(nèi)孔尺寸公差為hg或Hg。上述要求是對普通泵用機械密封的密封環(huán)而言，對轉(zhuǎn)速較低的釜用機械密封可適當(dāng)放寬或參考相應(yīng)的標(biāo)準(zhǔn)，而對高速機械密封則要求更高。五、平面度平面度。</p><p> 其抗拉強度和硬度增加而韌性下降.塑料和橡膠的低溫性能比金屬材料更為敏感.一般情況下，塑料和橡膠只能在-50℃以上的溫度范圍使用。對于低溫泵，資料[13]介紹:丁睛橡膠的使用溫度限為-60℃氯丁橡膠為-65℃，硅酮橡膠為-80℃，氟化橡膠為-45℃，聚四氟乙烯為-79℃，并認(rèn)為使用以上這些材料作填料的機械密封以-70℃為使用極限。如果介質(zhì)溫度在-70℃以下，則使用波紋管型機械密封或者雙端面機械密封.資料[6]介紹聚四氟乙烯在氦的沸點(℃)還能保持一點柔軟性，適宜做低溫材料，但聚四氟乙烯的膨脹系數(shù)大，所以在-50~-100℃溫度使用時，常采用四氟填充石墨或玻璃纖維，而不用純四氟材料.此外，在低溫時，V形圈裝到軸套上后，動環(huán)往往不能浮動。因此，要注意V形圈的組裝尺寸。關(guān)于低溫機械密封及低溫泵材料如表10-4所示。低溫時PTFE的機械性能如表10-5所示。2.結(jié)構(gòu)要求在一般的0~-50℃低溫下，常采用單端面機械密封，有非平衡或平衡型結(jié)構(gòu)，但多數(shù)選用平衡型結(jié)構(gòu)，這是因為密封端面的液休經(jīng)摩擦后溫度升高，液膜壓力隨之升高而將密封面推開，泄漏加劇。因此，低溫時的端面比壓要選高值。在液溫低于-70℃時，則采用波紋管密封或雙端面密封.不過使用雙端面密封時。黔江區(qū)宙斯泵用機械密封件廠家。</p><div

目前動環(huán)和軸套的密封方法可分為三類：輔助密封圈軸向安裝的動環(huán)、輔助密封圈徑向安裝的動環(huán)和帶波紋管的動環(huán)。輔助密封圈軸向安裝的動環(huán)（圖18），靠彈簧力壓緊密封圈來實現(xiàn)密封。彈簧力可視為不變化，密封可靠、使用壽一命長、安裝較方便，從而得到***應(yīng)用。輔助密封圈徑向安裝的動環(huán)（圖19），靠密封圈的過盈和彈性實現(xiàn)密封，其材料大多用聚四氟乙烯和合成橡膠。隨著使用時間的延長，這兩種材料分別出現(xiàn)冷流變形和老化而喪失彈性。有文獻(xiàn)記載，這種結(jié)構(gòu)的密封，有40%的失效發(fā)生在輔助密封圈部位。第三種動環(huán)是指波紋管型密封，將動環(huán)和波紋管制成一個整體（圖8），故不需要動環(huán)密封圈。靜環(huán)安裝在機器設(shè)備的殼體、壓蓋、法蘭等靜止部位上，它與動環(huán)組成的密封端面防止介質(zhì)泄漏，也有補償環(huán)和非補償環(huán)之分。當(dāng)補償機構(gòu)設(shè)計在動環(huán)一側(cè)時，密封端面磨損后，靜環(huán)不能進(jìn)行補償，叫做非補償型靜環(huán)。反之，稱為補償型靜環(huán)，當(dāng)密封端面磨損后，靜環(huán)在彈性元件作用下，做軸向移動進(jìn)行補償。非補償型靜環(huán)應(yīng)用較多，都用于旋轉(zhuǎn)型密封。靜環(huán)與壓蓋的密封和固定方式有兩種，一是浮動型，一是固定型。具體的結(jié)構(gòu)種類很多，圖20和圖21給出了較為典型的結(jié)構(gòu)。寶雞安德里茨泵用機械密封件廠家</p></p><br
