彈性力完全由波紋管產(chǎn)生，因此波紋管設(shè)計(jì)時要考慮其彈率。一般將波紋管的彈率設(shè)計(jì)得小些，當(dāng)要求一定的彈力時，波紋管的壓縮量就要適當(dāng)?shù)丶哟?。運(yùn)轉(zhuǎn)相當(dāng)長時間后，如果密封端面磨損，波紋管自動補(bǔ)償，而彈力降低不會大，始終保持密封端面有足夠的壓比。為保證足夠的彈性力，壓縮量在10mm左右，不能低于6mm。工作時每個波的變形以小為宜，為保證一定的壓縮量，要適當(dāng)增加波數(shù)，保持波距。一般波數(shù)取16～20，溫度和壓力高時波數(shù)宜取多。波紋管的彈率是幾何形狀和材料的函數(shù)，常用下式計(jì)算：k=πEt3(c)d2/2nB3d1式中k——波紋管彈率，N／mm；E——材料在工作溫度下的彈性模量，N/mm2；t——波片厚度，mmn——波紋管波數(shù)；d1、d2——分別為波紋管的內(nèi)外徑，mm；B——波紋管的片寬，mm。B=（d2-d1）／2公式中沒有考慮波片的斷面形狀等因素，因此有一定的誤差。實(shí)際工作中可在彈簧測力計(jì)上測量其彈率。普通彈簧的彈率計(jì)算在一般“機(jī)械零件”書上能找到，故在此不作介紹。非對稱型波紋管焊接金屬波紋管機(jī)械密封以其結(jié)構(gòu)簡單、伸縮性好和耐高溫等優(yōu)點(diǎn)，得到了日益廣的應(yīng)用，尤其是高溫泵的密封中，在有的國家已成為主要的軸封方式。國內(nèi)的焊接金屬波紋管密封質(zhì)量不夠穩(wěn)定。遼源石家莊工業(yè)泵泵用機(jī)械密封件廠家巫山襄樊五二五泵用機(jī)械密封件廠家。</p><div

七、目前應(yīng)用的密封種類根據(jù)制造方法和材料的不同，目前應(yīng)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(jié)構(gòu)。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(xué)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(dāng)?shù)臒崽幚砉に嚕蕴岣咂溆捕群湍湍バ?。這類材料價格較低，如果使用恰當(dāng)，也有較長的壽命。為了進(jìn)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(jié)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。</p><p>

也稱平直度）是密封環(huán)很重要的一個質(zhì)量指標(biāo)，要求在0．0009mm以內(nèi)，這樣的數(shù)量級用普通的量具是無法測量的。既準(zhǔn)確又迅速的方法是用光干涉法。它需要一個光學(xué)平晶和單色光源，一般用鈉光燈。檢測時，將平晶放到被檢的密封端面上，斜上方用鈉光燈照射（圖15）檢查干涉條紋的數(shù)量。鈉光的波長為0．6μm，每個干涉條紋為半個波長，即一條干涉條紋為0．3μm，由干涉條紋的數(shù)量即可確定密封端面的平面度。確定干涉條紋的數(shù)量：密封端面的平面度不同，條紋的種類也不同。圖16表示了幾種平面度合格的圖像，至于不合格的圖像各式各樣未予繪出。圖16a是平直的條紋，表明密封端面的平面度接近光學(xué)平晶的平面度，這種平面度高；圖16b是彎曲的條紋，干涉條紋數(shù)在一條以內(nèi)，即小于μm；圖16c也是彎曲的條紋，干涉條紋數(shù)二條，平面度在μm以內(nèi)；圖16d是同心圓狀的干涉條紋，如果是從平板研磨后取下來檢驗(yàn)平面度，這說明端面的內(nèi)緣高，外緣低，同心圓數(shù)量越多，其內(nèi)外緣高低差別越大。出面同心圓的條紋不要超過2個。六、動環(huán)和靜環(huán)動環(huán)可分為非補(bǔ)償型和補(bǔ)償型兩種。在靜止型機(jī)械密封中，采用非補(bǔ)償型動環(huán)，固在軸上，有的用軸套壓緊在軸上（圖3）。補(bǔ)償型動環(huán)***用于旋轉(zhuǎn)型機(jī)械密封中。薊州區(qū)襄樊五二五泵用機(jī)械密封件選型。晉州螺桿泵用機(jī)械密封件</p><p

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(shí)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(shí)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(jī)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(bǔ)償環(huán)和非補(bǔ)償環(huán)之分。當(dāng)補(bǔ)償機(jī)構(gòu)設(shè)計(jì)在動環(huán)一側(cè)時，密封端面磨損后，靜環(huán)不能進(jìn)行補(bǔ)償，叫做非補(bǔ)償型靜環(huán)。反之，稱為補(bǔ)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(bǔ)償。非補(bǔ)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)。沈陽螺桿泵用機(jī)械密封件</p><p
