壓力波動(dòng)不大于1公斤/平方厘米。c泵在運(yùn)轉(zhuǎn)中，應(yīng)避免發(fā)生抽空現(xiàn)象，以免造成密封面干摩擦及密封破壞。機(jī)械密封本身是一種要求較高的精密部件，對(duì)設(shè)計(jì)、機(jī)械加工、裝配質(zhì)量都有很高的要求。在使用機(jī)械密封時(shí)，應(yīng)分析使用機(jī)械密封的各種因素，使機(jī)械密封適用于各種泵的技術(shù)要求和使用介質(zhì)要求且有充分的潤(rùn)滑條件，這樣才能保證密封長(zhǎng)期可靠地運(yùn)轉(zhuǎn)。十二、機(jī)械密封摩擦副材料碳化硅。碳化硅陶瓷是近年發(fā)展的新材料。它具有很低的摩擦因數(shù)，很高的硬度，良好的耐磨性。它具有良好的化學(xué)穩(wěn)定性、耐熱性和抗熱振性。碳化硅有熱壓碳化硅、常壓燒結(jié)碳化硅和反應(yīng)燒結(jié)碳化硅。硬質(zhì)合金。硬質(zhì)合金主要是碳化鎢WC，分別有鈷基碳化鎢WC-Co、鎳基碳化鎢WC-Ni和鈷-鎳基碳化鎢WC-Co-Ni。碳化鎢的特點(diǎn)：硬度高，耐磨性好；機(jī)械強(qiáng)度高，抗彎性好；導(dǎo)熱率較高而膨脹系數(shù)較小，密封面摩擦熱容易導(dǎo)出；無(wú)鈷硬質(zhì)合金耐腐蝕性較好。機(jī)械輔助密封材料機(jī)械密封的輔助密封是保證密封可靠和延長(zhǎng)使用壽命的重要零件。輔助密封包括動(dòng)、靜環(huán)的輔助密封圈。其作用是保證密封的軸與動(dòng)環(huán)之間的靜環(huán)座（壓蓋）與靜環(huán)之間密封，補(bǔ)償密封面的偏斜和振動(dòng)；保證使動(dòng)、靜環(huán)端面緊密結(jié)合具有浮動(dòng)性。</p><p> 一般O形圈安裝后壓縮變形量應(yīng)在18%～22%之間，截面尺寸大時(shí)壓縮相對(duì)變形量較小，而截面尺寸較小時(shí)壓縮相對(duì)變形量則較大。2、O形密封圈的公稱尺寸與實(shí)際安裝尺寸相差太多，形成O形圈在拉伸后截面尺寸縮小的狀況下工作，造成壓縮變形量不足而產(chǎn)生泄漏。3、O形密封圈在安裝時(shí)，由于密封面的進(jìn)口沒(méi)有光滑的倒角或倒圓而將O形圈劃傷而產(chǎn)生泄漏。4、O形密封圈的材質(zhì)不適用于密封介質(zhì)而被侵蝕后失效。5、O形密封圈使用時(shí)間太久后老化變質(zhì)，彈性降低后而失效，所以在設(shè)備大修時(shí)一般都將O形圈更換。另外，O形密封圈的硬度，溝槽和密封面的粗糙度也影響O形密封圈的密封效果。填料密封將富有壓縮性和回彈性的填料放入填料函內(nèi)，依靠壓蓋的軸向壓緊力轉(zhuǎn)化為徑向密封力，從而起到密封作用。這種密封方法稱為填料密封，這種填料稱為密封填料。由于填料密封結(jié)構(gòu)形式簡(jiǎn)單，更換方便、價(jià)格低廉、適應(yīng)轉(zhuǎn)速、壓力、介質(zhì)寬泛而在泵的設(shè)計(jì)中得到普遍采用。輸送常溫介質(zhì)時(shí)，填料密封一般都設(shè)有填料環(huán)，其或與泵的高壓腔相通，或外接具有一定壓力的液體介質(zhì)，可起到冷卻、潤(rùn)滑、密封或沖洗作用。由于填料密封是一種接觸密封，因此必然存在磨擦和磨損問(wèn)題。而磨擦和磨損的大小。天津格蘭富機(jī)械密封大全。</p><div

螺紋密封螺紋密封在泵上一般有兩種形式，一種是螺紋聯(lián)接墊片密封，一種是螺紋加填充濟(jì)密封，二者皆用于小直徑螺紋連接的密封場(chǎng)合。螺紋聯(lián)接墊片密封的密封件是墊片，而螺紋只起提供壓緊力的作用。密封的效果除了墊片的本身性能外。密封面的粗糙度以及與螺紋孔的相對(duì)幾何位置精度對(duì)密封效果影響也很大。于由密封墊片在擰緊螺紋時(shí)不僅承受壓緊力，還承受扭矩，使墊片產(chǎn)生變形甚至損壞，因此，當(dāng)墊片為非金屬時(shí)，一般只適用于壓力不高的場(chǎng)合，如果墊片為金屬則適用壓力可達(dá)30Mpa以上。泵上經(jīng)常使用的絲堵，則是另一種螺紋密封形式。由于考慮到絲堵制造的經(jīng)濟(jì)性，一般單靠螺紋的配合不能起到密封作用，往往用生膠帶，密封膠等填充物填充螺紋的密封間隙。其承壓能力取決于螺紋的制造精度和材質(zhì)，與絲堵和螺紋孔的配合形式?jīng)]有關(guān)系。螺紋孔與絲堵無(wú)論采用"錐對(duì)錐"還是"柱對(duì)錐"，密封效果相同，只是使用地域不同而已。我國(guó)目前兩種形式同等采用。影響密封效果的常見(jiàn)原因是在加工螺紋底孔時(shí)尺寸偏大，使螺紋牙形變短，牙頂變寬，造成密封面減小，當(dāng)密封壓力升高后產(chǎn)生泄漏，甚至將絲堵壓出。由于填充物被密封介質(zhì)腐蝕而產(chǎn)生泄漏的現(xiàn)象在化工行業(yè)的用泵中也時(shí)有發(fā)生。福建格蘭富機(jī)械密封大全。晉城格蘭富機(jī)械密封CR45-2-2</p><p

國(guó)產(chǎn)碳化鎢硬質(zhì)合金的物理—力學(xué)性機(jī)械密封對(duì)輔助密封圈材料的要求：1）材料彈性好，特別是要求良好的復(fù)原性，長(zhǎng)久變形要??；2）不受流體介質(zhì)的侵蝕，而且在介質(zhì)中的膨脹和收縮都不大；3）摩擦因數(shù)小和耐磨性好；4）使用溫度范圍要廣，在高、低溫下不粘著、不變硬、脆和失彈；5）要有適當(dāng)?shù)牧W(xué)性能，如扯斷強(qiáng)度及其延伸率、耐壓等，在壓力作用下無(wú)顯著變形，有優(yōu)良的抗撕裂性、耐磨性和耐壓性等；6）便于加工并可得到高的精度；7）抗介質(zhì)腐蝕、溶解、溶脹、老化等性能好，對(duì)介質(zhì)不應(yīng)有污染等。作為輔助密封圈的材料有橡膠、塑料、石棉、膨脹石墨、石墨和金屬脹圈等。橡膠圈是使用**廣的一種輔助密封圈。常用的橡膠密封圈材料有丁腈橡膠、氟橡膠、硅橡膠、氯丁橡膠、丁苯橡膠等。丁腈橡膠是常用的一種耐油橡膠。它是丁二烯和丙烯腈的共聚物。根據(jù)丙烯腈含量多少分成若干種：低丙烯腈（丁腈-18）、中丙烯腈（丁腈-26）和高丙烯腈（丁腈-40）、丙烯腈含量越高，它的耐油性越好，抗張強(qiáng)度、硬度和耐磨性、耐水性增加，透氣性減小。隨之而來(lái)，它在極性溶劑中是溶解度卻增大，耐腐蝕性也受到影響，彈性和耐寒性也變差。丁腈橡膠不耐撓曲，抗撕裂也較差。晉城格蘭富機(jī)械密封CR45-2-2</p></p><br
