1.沖洗方案01方案：從泵的出口端沖洗內(nèi)機(jī)械密封腔。操作類似方案PLAN11原因:密封腔冷卻，臥式泵的密封腔排氣，防止PLAN11方案外露管的凍結(jié)和流體結(jié)晶堵塞的危險(xiǎn)場(chǎng)合：普通密封腔，**可能是ANSI/ASME泵，清潔常溫流體，用于單端面密封，很少用于雙斷面密封。維護(hù)：沖洗不能直接沖洗密封面，機(jī)封冷卻不能過度，根據(jù)通過內(nèi)截流管的揚(yáng)程損失計(jì)算沖洗流量。2.沖洗方案02方案：無沖洗的封閉密封腔。原因：不需要流體二次循環(huán)。使用場(chǎng)合：常溫運(yùn)轉(zhuǎn)下的大孔/開口密封腔，高溫運(yùn)轉(zhuǎn)下的冷卻套密封腔，清潔流體，干式密封的直立/頂入式混和器/攪拌器，維護(hù)：流程必須有足夠的沸點(diǎn)臨界空間，避免汽化，在熱運(yùn)轉(zhuǎn)條件下，密封腔套內(nèi)可能需要一直有冷卻液體，臥式設(shè)備必能自己排氣，經(jīng)常和冷卻方案PLAN62聯(lián)合使用。3.沖洗方案11方案：從泵出口處經(jīng)過限流孔板進(jìn)行機(jī)械密封沖洗，違反單端面機(jī)械密封沖洗方案。原因：密封腔的冷卻，臥式密封腔的排氣，增加密封腔的壓力和流體汽化臨界空間。場(chǎng)合：通常用于清潔流體，清潔、非聚合流體。維護(hù)：使用孔徑**小為，計(jì)算流量以確定使機(jī)封腔流量足夠的限流孔板尺寸，通過合適的限流孔板和喉部襯套尺寸來確定增加沸點(diǎn)臨界范圍。大慶2009釜用機(jī)械密封件大全潮州反應(yīng)釜用機(jī)械密封件。</p><div

機(jī)械密封是用于密封旋轉(zhuǎn)軸與靜止泵腔的機(jī)械部件。被密封部分為圓柱形區(qū)域，設(shè)備中的軸旋轉(zhuǎn)并且貫穿設(shè)備內(nèi)外，機(jī)體部分靜止且內(nèi)部充滿流體介質(zhì)。在壓力差、濃度差、溫度差等驅(qū)動(dòng)下，設(shè)備內(nèi)外流體相互交換；“密封”意味著控制內(nèi)外區(qū)域間流體的交換，使界面處“沒有泄露”現(xiàn)象。布赫特在《工業(yè)密封技術(shù)》一書中是這樣解釋的：機(jī)械密封是一個(gè)由一系列簡(jiǎn)單設(shè)計(jì)元件組成的組合機(jī)構(gòu)，密封作用由兩個(gè)帶平面的主密封環(huán)完成，以防止泄漏。其中一個(gè)密封環(huán)與軸連在一起轉(zhuǎn)動(dòng)，另一個(gè)密封環(huán)固定在殼體上。為了密封離心泵軸，靜密封環(huán)安裝在密封腔壓蓋上。在泵軸轉(zhuǎn)動(dòng)期間，裝在軸上的密封環(huán)的密封面與對(duì)面的靜環(huán)密封面相摩擦。這兩個(gè)密封接觸面的接觸作用類似軸承，并且受到磨損。任何形式的系統(tǒng)泄漏都必須通過這個(gè)密封接觸面。作用在軸向的力使密封環(huán)始終保持摩擦接觸，其來源可以為機(jī)械的或者是液壓的，在很多設(shè)計(jì)中，取兩者之和。這種穩(wěn)定的接觸可以防止從摩擦面間泄漏或使泄漏量減到小。機(jī)械密封按照應(yīng)用的主機(jī)分類可分為泵用密封、釜用密封、壓縮機(jī)用密封等。泵用密封包括各種離心泵、旋渦泵、螺桿泵、內(nèi)燃機(jī)冷卻水泵，船用泵等。</p><p> 無軸套有效保護(hù)機(jī)泵：焊接波紋管機(jī)械密封因沒有O型環(huán)，不需要安裝軸套，所以不會(huì)發(fā)生O型環(huán)的磨蝕引起的軸或軸套的磨損，從而起到保護(hù)泵走的作用適用于腐蝕性流體：只要選用耐腐蝕性高的哈氏合金276等材料制造焊接波紋管同樣避免了彈簧和O型環(huán)的腐蝕問題，有效實(shí)現(xiàn)密封。不會(huì)發(fā)生懸掛泄漏：普通的推環(huán)式機(jī)械密封，泄漏出來的微量流體遇空氣會(huì)固化沉積，阻止O型動(dòng)環(huán)的前進(jìn)，使密封端面的貼合力變?nèi)趸蛳?，從而?dǎo)致泄漏。相反焊接波紋管機(jī)械密封沒有O型環(huán)圈，即使有固化，影響也不大，仍可安穩(wěn)地旋轉(zhuǎn)，故適用壽命較長(zhǎng)。具有螺紋泵送作用：波紋管本身具有螺紋泵送作用，可有效對(duì)應(yīng)含固體顆粒的流體，并有助于沖洗。機(jī)械密封與填料密封對(duì)比：與填料密封相比，機(jī)械密封具有密封性能可靠、泄漏量小、壽命長(zhǎng)等優(yōu)點(diǎn)。可用于各種不同粘度、強(qiáng)腐蝕性和含顆粒的介質(zhì)。機(jī)械密封適用于輸送石油及化工介質(zhì)。但是機(jī)械密封價(jià)格貴，加工安裝維修保養(yǎng)比一般密封要求高。填料密封結(jié)構(gòu)簡(jiǎn)單、價(jià)格便宜、維修方便，但泄漏量大、功率損失大。因此，填料密封用于輸送一般介質(zhì)，如水；不適用于石油及化工介質(zhì)，特別是不能用在貴重、易爆和有毒介質(zhì)中。威海M481釜用機(jī)械密封件。</p><div
