?密封裝置功用:防止液壓油的泄漏 對(duì)密封裝置的要求:良好的密封性、耐磨性、經(jīng)濟(jì)性 常見密封形式 (1)間隙密封 (2)密封圈密封 間隙密封密封原理:利用相對(duì)運(yùn)動(dòng)零件配合面之間的微小間隙來防止泄漏 間隙密封平衡槽作用 1)自動(dòng)對(duì)中心,減小摩擦力 2)增大了泄漏阻力,減小了偏心量,提高了密封性能。

3)儲(chǔ)存油液,自動(dòng)潤(rùn)滑間隙密封特點(diǎn)應(yīng)用 ∵  結(jié)構(gòu)簡(jiǎn)單,摩擦阻力小,耐高溫,但泄漏較大,并且隨著時(shí)間的增加而增加,加工要求高 ∴ 主要用于尺寸小,壓力低,速度高的液壓缸或各種閥 密封圈類型:O、LX、Y、V型和組合式等 密封圈材料:耐油橡膠、尼龍 O型密封圈密封原理:密封圈的安裝變形用于密封 O型密封圈特點(diǎn) ∵  O型圈截面為圓形,結(jié)構(gòu)簡(jiǎn)單,制造方便,密 封性能好,摩擦力小。

∴  一般安裝在外圓或內(nèi)圓上截面為矩形的溝槽 內(nèi)以實(shí)現(xiàn)密封 又∵  O型圈一般為橡膠制成 運(yùn)動(dòng)密封(動(dòng))— p>10Mpa ∴ 壓力高時(shí)32Mpa, O型密封圈應(yīng)用相當(dāng)廣泛,既可用于動(dòng)密封,又可用于靜密封 Y型密封圈密封原理:密封圈受油壓作用使兩唇張開并貼緊在軸或孔的表面實(shí)現(xiàn)密封。

Y型密封圈分類 根據(jù)截面長(zhǎng)寬比例不同 分為寬斷面 和窄斷面 Y型密封圈特點(diǎn) ∵  Y型圈靠唇邊張開后實(shí)現(xiàn)密封 ∴ 安裝時(shí)唇邊必須對(duì)著壓力油腔 又∵  Y型圈密封可靠,摩擦力小,壽命長(zhǎng) ∴  常用于速度較高的液壓缸 Y型密封圈應(yīng)用 寬斷面Y型密封圈:p<20Mpa 00 T在-30—+100 通常 窄斷面Y型密封圈:p<32Mpa 00 T在-30—+100 V型密封圈結(jié)構(gòu):截面為V型,由支承環(huán)、密封環(huán)、壓緊環(huán)疊合而成,開口面向高壓側(cè)。

V型密封圈密封原理:當(dāng)壓緊環(huán)壓緊密封環(huán)時(shí),支承環(huán)使密封環(huán)產(chǎn)生變形而實(shí)現(xiàn)密封 V型密封圈特點(diǎn)應(yīng)用 ∵  V型密封圈是組合裝置 ∴  密封效果良好,耐高壓,壽命長(zhǎng),增 加密封環(huán)可提高密封效果,但摩阻力增大,尺寸大,成本高。

故 常用于壓力較高p<50Mp),溫 度為-400—+800,運(yùn)動(dòng)速度較低的場(chǎng)合實(shí)現(xiàn)密封 油封的功用:設(shè)置在液壓泵或液壓馬達(dá)的伸軸處,對(duì)外防塵,對(duì)內(nèi)防漏 油封的分類:骨架式、無骨架式 油管  ——傳遞工作液體 管接頭——連接油管與 油管 或元件 要 求:足夠的強(qiáng)度、良好的密封、較小的壓力損失、方便的裝拆性。

油管尺寸的計(jì)算 計(jì)算依據(jù):q、p 計(jì)算參數(shù):d、δ 公式:d=2√q/πv 對(duì)橡膠軟管,由p和d選標(biāo)準(zhǔn) d算出后<中低壓,選標(biāo)準(zhǔn)規(guī)格 金屬管0、5 mm 管接頭要求:連接牢固、密封可靠、裝配方便、工藝性好、外形尺寸小、通油能力強(qiáng)。

管接頭分類 按接頭分 1     硬管接頭 2     插入快換式接頭 3     膠管接頭 4     快速接頭 按連接體形式分 普通細(xì)牙螺紋(高壓) 錐螺紋(中低壓) 90-L-075-KA-1-CD-60-S-3-T2-D-03-GBA-35-35-24 90L075KA1CD60S3T2D03GBA353524
