而對密封面進行冷卻，能有效地防止熱裂，殘留在密封面上的固體微粒經常損壞表面，如磨削時砂輪上的砂粒就會損傷硬環(huán)表面，導致密封面打開或在密封面之間生成結晶物，而在重新研磨石墨環(huán)后，研磨料就會嵌入石墨環(huán)表面。橡膠圈的失效與使用方式有關，通常高壓是使壓制成型的○型圈失效的一個原因，當發(fā)現(xiàn)○型變成矩形或環(huán)變硬時，就需要調整壓縮量，否則會發(fā)熱。所以有必要了解一種合成橡膠的使用溫度。合成橡膠圈溶脹大多半是因化學侵蝕造成的，它們都具有一些各自的特點，如氟橡膠耐較高溫度，而乙烯、丙烯○型圈在石油潤滑油中使用會脹大，臭氧對丁晴橡膠有侵蝕作用，所以丁晴橡膠制品不要裝在電動機內，因此高溫及化學腐蝕通常是造成橡膠制品硬化、裂紋的主要原因。安裝時橡膠制件被割傷和表面有刻痕，也是密封失效常見的原因。而軸上的舊固定螺釘、鍵槽、花鍵軸，鋒利的軸肩等跡象都會損傷橡膠制件。這里，對于密封面磨損痕跡尚需補充以下幾點，長春連成水泵機械密封SLOW350-520，檢查磨損痕跡，可以幫助分析故障，長春連成水泵機械密封SLOW350-520，長春連成水泵機械密封SLOW350-520。1，磨損變寬：表明機泵發(fā)生了嚴重的不對中。其原因是：（1）軸承損壞；（2）軸振動或軸變形；（3）軸彎曲；（4）泵汽蝕產生振動；（5）聯(lián)軸器未對中；（6）管子嚴重變形；（7）密封靜環(huán)傾斜。遼寧連成水泵機械密封。長春連成水泵機械密封SLOW350-520</p><div

5)石棉橡膠墊圈：由石棉橡膠板剪成。它的組分是60～80%的石棉和10～20%的橡膠，以及填充劑、硫化劑等。它有很好的耐熱性、耐冷性、化學穩(wěn)定性，而且貨源豐富，價格便宜。使用時，壓緊力不必很大。由于它能粘附金屬，所以**好表面涂一層石墨粉，以免拆卸時費勁。石棉橡膠板有四種顏色：灰色，用于低壓(牌號XB-200，耐壓≤16公斤/平方厘米，耐溫200℃)；紅色，用于中壓(牌號XB-350，耐壓可達40公斤/平方厘米，耐溫350℃)；紫紅色，用于高壓(牌號XB-450，耐壓100公斤/平方厘米耐溫450℃)；綠色，用于油類，耐壓性能也很好。(6)金屬平熱圈：鉛，耐溫100℃；鋁430℃；銅315℃；低碳鋼550℃；銀650℃；鎳810℃；蒙乃爾(鎳銅)合金810℃，不銹鋼870℃。其中鉛耐壓能力較差，鋁可耐64公斤/平方厘米，其他材料可耐高壓。(7)金屬異性墊圈：透鏡墊圈：有自緊作用，使用于高壓閥門。橢圓形墊圈：也屬于高壓自緊墊圈。錐面雙墊圈：用于高壓內自緊密封。此外，還有方形、菱形、三角形、齒形、燕尾形、B形、C形等，一般只在高中壓閥門中使用。(8)金屬包皮墊圈：金屬既有良好的耐溫耐壓性能，又有良好的彈性。包皮材料有鋁、銅、低碳鋼、不銹鋼、蒙乃爾合金等。綏化連成水泵機械密封IH100-80-125大連連成水泵機械密封。</p><div

常用墊圈性能---及新材料和新技術一)常用墊圈性能使用閥門時，往往根據具體情況，更換原帶墊圈。常有墊圈有：橡膠平墊圈、橡膠O形圈、塑料平墊圈、聚四氟乙烯包墊圈、石棉橡膠墊圈、金屬平墊圈、金屬異形墊圈、金屬包皮墊圈、波形墊圈、纏繞墊圈等。(1)橡膠平墊圈：變形容易，壓緊時不費力，但耐壓、耐溫能力都較差，只用于壓力低、溫度不高的地方。天然橡膠有一定耐酸堿性能，使用溫度不宜超過60℃；氯丁橡膠也能耐某些酸堿，使用溫度80℃；丁腈橡膠耐油，可用至80℃；氟橡膠耐腐蝕性能很好，耐溫性能也比一般橡膠強，可在150℃介質中使用。(2)橡膠O形墊圈：斷面形狀是正圓，有一定的自緊作用，密封效果比平墊圈好，壓緊力更小。(3)塑料平墊圈：塑料的**大特點是耐腐蝕性好,大部分塑料耐溫性能不好。聚四氟乙烯為塑料之冠，不但耐腐蝕性能優(yōu)異，而且耐溫范圍比較寬闊，可在-180℃～+200℃之內長期使用。(4)聚四氟乙烯包墊圈：為了充分發(fā)揮聚四氟乙烯的優(yōu)點，同時彌補它彈性較差的缺點，做成聚四氟乙烯包裹橡膠或石棉橡膠的墊圈。這樣，既同聚四氟乙烯平墊圈一樣耐腐蝕，又有良好的彈性，增強密封效果，減小壓緊力。其斷面形狀如圖4-20所示。。</p><p>
