機(jī)械密封是旋轉(zhuǎn)軸用動(dòng)密封，分為接觸式和非接觸式兩種，目前多數(shù)采用接觸式機(jī)械密封，而非接觸式機(jī)械密封正在發(fā)展之中，并已引起人們注意.機(jī)械密封是機(jī)器上的非功能性零部件，但它在減少泄漏，穩(wěn)定生產(chǎn)上起了很大作用。機(jī)械密封的工作原理機(jī)械密封是用于旋轉(zhuǎn)鐘的動(dòng)密封，又稱端面密封，其主要特點(diǎn)是密封面垂直于(或大致)旋轉(zhuǎn)軸線，并且由彈性元件、輔助密封圈等構(gòu)成的軸向磨損補(bǔ)償機(jī)構(gòu)，沈陽(yáng)MECP-LK4-100D110ZZ襄樊五二五機(jī)械密封。機(jī)械密封的工作原理就是以兩個(gè)相互貼合，平的與旋轉(zhuǎn)軸線垂直的密封表面，并相對(duì)轉(zhuǎn)動(dòng)的密封裝置。它是靠彈性元件(如彈簧或波紋管)和密封介質(zhì)的壓力，隨軸旋轉(zhuǎn)的動(dòng)環(huán)和不隨軸旋轉(zhuǎn)的靜環(huán)的接觸端而上產(chǎn)生適當(dāng)?shù)膲壕o力，使這兩個(gè)接觸端面緊密貼合，端面間維持一層極薄的液膜，從而達(dá)到密封的目的。機(jī)械密封AIG318集裝式/以一臺(tái)單級(jí)臥室雙吸油泵為例/機(jī)械密封的作用一、提高機(jī)器效率、降低能耗。1，沈陽(yáng)MECP-LK4-100D110ZZ襄樊五二五機(jī)械密封、減少機(jī)器的內(nèi)漏、外漏和穿漏，提高機(jī)器容積效率。例如，大慶煉油廠將焦化5FDJ5×2離心泵的葉輪口環(huán)改為機(jī)械密封，使泵效率提高。2、減少摩擦損失，提高機(jī)器的機(jī)械效率。例如，將雙端面密封改為單端面密封，沈陽(yáng)MECP-LK4-100D110ZZ襄樊五二五機(jī)械密封、非平衡型改為平衡型、雙支承減底泵封閉一端(所謂砍頭泵)減少密封都能減少摩擦損失。IH-60D100ZZ襄樊五二五機(jī)械密封。沈陽(yáng)MECP-LK4-100D110ZZ襄樊五二五機(jī)械密封</p><div

1、基本結(jié)構(gòu)副葉輪動(dòng)力密封通常由副葉輪、副葉片（又叫背葉片）、固定導(dǎo)葉和停車密封裝置等組成，如圖1所示。2、主要部件的作用（1）副葉片的作用是減低泵腔的壓力，達(dá)到平衡軸向力和防止顆粒進(jìn)入密封裝置的目的，常用于抽送含有雜質(zhì)的泵。（2）副葉輪實(shí)際是一個(gè)小離心泵葉輪，靠它產(chǎn)生的壓頭頂住工作葉輪出口的高壓液體向外泄漏。（3）固定導(dǎo)葉的作用是消除液體的旋轉(zhuǎn)，在無(wú)固定導(dǎo)葉時(shí)，副葉輪光背側(cè)的液體以角速度旋轉(zhuǎn)，壓力呈拋物線規(guī)律分布。副葉輪光背側(cè)下部的壓力小于副葉輪外徑處的壓力。如果有固定導(dǎo)葉，則可防止液體旋轉(zhuǎn)，光背側(cè)下部的壓力和副葉輪外徑處的壓力差不多，這就提高了副葉輪的封堵壓力。（4）油封（停車密封）作用。因?yàn)楦比~輪只在泵運(yùn)行時(shí)起密封作用，停車密封裝置可以在泵停車時(shí)，擋住該余壓液體往外泄漏。因此，停車密封應(yīng)具備兩種功能：當(dāng)停車時(shí)應(yīng)確保及時(shí)封堵，以防泄漏；而運(yùn)行時(shí)則應(yīng)能及時(shí)松開，以免密封面磨損而耗能。在實(shí)際應(yīng)用中，停泵密封采用了三道油封一道擋水環(huán)來(lái)起密封作用。將動(dòng)力密封總成組裝好后替換離心泵機(jī)械密封總成即可。根據(jù)改進(jìn)對(duì)象相應(yīng)改變軸套及前后蓋板外型尺寸。泵除機(jī)械密封（或其它密封裝置）被替換外。HTM-40S251襄樊五二五機(jī)械密封。沈陽(yáng)MECP-LK4-100D110ZZ襄樊五二五機(jī)械密封</p><p

機(jī)械密封是靠一對(duì)或數(shù)對(duì)垂直于軸作相對(duì)滑動(dòng)的端面在流體壓力和補(bǔ)償機(jī)構(gòu)的彈力（或磁力）作用下保持貼合并配以輔助密封而達(dá)到阻漏的軸封裝置。水泵常用機(jī)械密封結(jié)構(gòu)如圖所示。由靜止環(huán)（靜環(huán)）1、旋轉(zhuǎn)環(huán)（動(dòng)環(huán)）2、彈性元件3、彈簧座4、緊定螺釘5、旋轉(zhuǎn)環(huán)輔助密封圈6和靜止環(huán)輔助密封圈8等元件組成，防轉(zhuǎn)銷7固定在壓蓋9上以防止靜止環(huán)轉(zhuǎn)動(dòng)。旋轉(zhuǎn)環(huán)和靜止環(huán)往往還可根據(jù)它們是否具有軸向補(bǔ)償能力而稱為補(bǔ)償環(huán)或非補(bǔ)償還。機(jī)械密封中流體可能泄漏的途徑有如圖1中的A、B、C、D四個(gè)通道。C、D泄漏通道分別是靜止環(huán)與壓蓋、壓蓋與殼體之間的密封，二者均屬靜密封。B通道是旋轉(zhuǎn)環(huán)與軸之間的密封，當(dāng)端面摩擦磨損后，它僅僅能追隨補(bǔ)償環(huán)沿軸向作微量的移動(dòng)，實(shí)際上仍然是一個(gè)相對(duì)靜密封。因此，這些泄漏通道相對(duì)來(lái)說(shuō)比較容易封堵。靜密封元件常用的有橡膠O形圈或聚四氟乙烯V形圈，而作為補(bǔ)償環(huán)的旋轉(zhuǎn)環(huán)或靜止環(huán)輔助密封，有時(shí)采用兼?zhèn)鋸椥栽δ艿南鹉z、聚四氟乙烯或金屬波紋管的結(jié)構(gòu)。A通道則是旋轉(zhuǎn)環(huán)與靜止環(huán)的端面彼此貼合作相對(duì)滑動(dòng)的動(dòng)密封，它是機(jī)械密封裝置中的主密封，也是決定機(jī)械密封性能和壽命的關(guān)鍵。因此，對(duì)密封端面的加工要求很高。沈陽(yáng)MECP-LK4-100D110ZZ襄樊五二五機(jī)械密封</p></p><br
