品、藥劑但耐油性差。氯丁橡膠CRCR壓耐磨性、耐風(fēng)化性和耐油性能氣好，但在苯胺點(diǎn)低的礦物油中易膨脹用于液壓密封時，只適用于苯胺點(diǎn)高的液壓油，特別適用于陽光照射下的氣動機(jī)械，其彎折性好，最適宜制作隔膜式密封元器件。使用溫度-30℃～+120℃丁基橡膠IIRIIR耐化學(xué)藥品、藥劑耐藥品性（特別是無機(jī)酸好，氣體滲透性小，適宜于作真空密封件材料在一般礦物油中不能使用只適用于氣壓、真空、鹽酸硫酸等無機(jī)酸中。使用溫度-50℃～+150℃聚丙烯酸脂膠ACMACM耐油、耐高溫耐溫、耐磨性好，耐堿、耐水性比NBR差。價格較NBR高使用溫度-40℃～+150℃聚四氟乙烯PTFEPTFE超低高溫、高壓具有介質(zhì)相容性、工作溫度范圍寬，承壓范圍大，但價格昂貴。除水以外的各種介質(zhì)，溫度范圍可取-190℃～+250℃.密封形式按負(fù)載類型可分為靜密封和動密封；按密封用途可分為孔用密封、軸用密封和旋轉(zhuǎn)軸密封；按其安裝形式又可分為徑向安裝和軸向安裝。徑向安裝時，對于軸用密封，應(yīng)使O形圈內(nèi)徑和被密封直徑d2間的偏差盡可能地?。粚τ诳子妹芊?，應(yīng)使其內(nèi)徑等于或略小于溝槽的直徑d1。侵向女裝.*密封和動由封軸向安裝時,要考慮壓力方向.內(nèi)部壓力時,O形圈外徑應(yīng)比溝槽外徑d3約大1～2％；外部壓力時,應(yīng)使O形圈內(nèi)徑比溝槽內(nèi)徑d4約小1～3％。三、影響密封性能的其它因素1、O形圈的硬度O形圈材料硬度是評定密封性能最重要的指標(biāo)。硬度決定了O形圈的壓縮量和溝槽最大允許擠出間隙。由于邵氏A70的丁晴密封都能滿足大部分的使用條件，故對密封材料不作特殊說明，一般提供邵氏A70的丁晴橡膠。2、擠出間隙最大允許擠出間隙gmax和系統(tǒng)壓力、O形圈截面直徑以及和材料的硬度有關(guān)。通常，工作壓力越高，最大允許擠出間隙gmax取值越小。如果間隙g超過允許范圍，就會導(dǎo)致O形圈被擠出損壞。最大允許擠出間隙gmax壓力MPaO形圈截面直徑W1.782.623.535.337.00邵氏硬度A70≤3.500.080.090.100.130.15≤7.000.050.070.080.090.10≤10.500.030.040.050.070.08邵氏硬度A80≤3.500.100.130.150.180.20≤7.000.080.090.100.130.15≤10.500.050.070.080.090.10≤14.000.030.040.050.070.08≤17.500.020.020.030.030.04邵氏硬度A90≤3.500.130.150.200.230.25≤7.000.100.130.150.180.20≤10.500.070.090.100.130.15≤14.000.050.070.080.090.10≤17.500.040.050.070.080.09≤21.000.030.040.050.070.08≤35.000.020.030.030.040.04注：1、當(dāng)壓力超過5MPa時，建議使用擋圈；2、對靜密封應(yīng)用場合，推薦配合為H7/g6。3、壓縮永久變形評定O形圈密封性能的另一指標(biāo)，即該材料的壓縮永久變形。在壓力作用下，作為彈性元件的O形圈，產(chǎn)生彈性變形，隨著壓力增大，會出現(xiàn)永久的塑性變形。壓縮永久變形d可由下式確定：*W0-U2bOblX1OO%*W0-U2bOblX1OO%式中：b0-原始厚度（截面直徑W），b1-壓縮狀態(tài)下的厚度，b2-釋放后的厚度通常，為防止出現(xiàn)永久的塑性變形，O形圈允許的最大壓縮量在靜密封中約為30％，在動密封中約為20％。擠出間HL4、預(yù)壓縮量O形圈安裝在溝槽里，為保證其密封性能，應(yīng)預(yù)留一個初始壓縮量。對于不同的應(yīng)用場合，相對于截面直徑W的預(yù)壓縮量也不同。通常，在靜密封中約為15％～30％，而在動密封中約為9％～25％。具體可參照下面圖表進(jìn)行選擇。5、拉伸與壓縮將O形圈安裝在溝槽內(nèi)時，要受到拉伸或壓縮。若拉伸和壓縮的數(shù)值過大，將導(dǎo)致O形圈截面過度增大或減少，因為拉伸1％相應(yīng)地使截面直徑W減少約為0.5％。對于孔用密封，O形圈最好處于拉伸狀態(tài)，最大允許拉伸量為6％；對于軸用密封，O形圈最好延其周長方向受壓縮，最大允許周長壓縮量為3％。6、O形圈用作旋轉(zhuǎn)軸密封O形圈也可用作低速旋轉(zhuǎn)運(yùn)動及運(yùn)行周期較短的旋轉(zhuǎn)軸密封。當(dāng)圓周速度低于0.5m/s時，須考慮拉長的橡膠圈受熱后會收縮這一現(xiàn)象，故選擇密封圈時其內(nèi)徑要比被它密封的軸徑約大2％。密封圈安裝在溝槽后，導(dǎo)致密封圈受到徑向壓縮，O形圈圈在溝槽中形成微量波紋狀，從而改善了潤滑條件。7、安裝壓縮力安裝時，壓縮力跟初始壓縮的程度和材料硬度有關(guān)。下面圖示為每厘米密封周長上的單位壓縮力和截面直徑間的關(guān)系，用以估算安裝O形圈時所需的總力大小。液壓/動密封：預(yù)壓縮允許范圍 液壓、氣動/靜密封：預(yù)壓縮允許范圍1%/圈％21%/圈％2直友；彳/圈A/直5；氣動/動密封：預(yù)壓縮允許范圍和材料有關(guān)的氣動/動密封：預(yù)壓縮允許范圍和材料有關(guān)的O形圈圓周方向的壓縮力HJ 1?X X興!3456 】0形圈截面直徑N圓周方向的壓!3456 】0形圈截面直徑N圓周方向的壓i?力F四、O形圈安裝設(shè)計1、O形圈安裝在溝槽內(nèi)時，應(yīng)允許它有一定的膨脹空間。通常，允許的膨脹率在
