液壓系統(tǒng)油箱的結(jié)構(gòu)設(shè)計(jì)及其注意事項(xiàng)。供大家參考學(xué)習(xí)，趕緊看看吧！

1、液壓系統(tǒng)的油箱應(yīng)有足夠的容量。油箱的總?cè)萘堪ㄓ鸵喝萘亢涂諝馊萘?。油液容量一般?yīng)在最高液面以上留出等于油液容量的10%~15%的空氣容量，以便形成油液的自由表面，容納熱膨脹和泡沫，促進(jìn)空氣分離，容納停機(jī)或檢修時(shí)靠自重流回油箱的油液。

2、以常用的矩形開式油箱為例，油箱的結(jié)構(gòu)設(shè)計(jì)注意事項(xiàng)如下。

（1）、油箱的三個(gè)邊的尺寸比例通?？砂淳唧w使用情況在1：1：1～1：2：3之間分配，并使液面高度為油箱高度的80%。

（2）、油箱的箱頂結(jié)構(gòu)取決于它上面安裝的元件，頂板應(yīng)具有足夠的剛度和隔振措施，以免因振動(dòng)影響液壓系統(tǒng)工作；箱頂應(yīng)能形成滴油盤以收集滴落的油液。箱頂上要設(shè)置通氣器（空氣過濾器）、注油口。

（3）、對(duì)于鋼板焊接的油箱，用來構(gòu)成油箱體的鋼板應(yīng)具有足夠的厚度。當(dāng)箱頂與箱壁之間為不可拆連接時(shí)，應(yīng)在箱壁上至少設(shè)置一個(gè)清洗孔。清洗孔的數(shù)量和位置應(yīng)便于用手清理油箱所有內(nèi)表面，清洗孔的法蘭蓋板應(yīng)配有可以重復(fù)使用的彈性密封件。為了便于油箱的搬運(yùn)，應(yīng)在油箱四角的箱壁上方焊接圓柱形和鉤形吊耳（也稱吊環(huán)）。液位計(jì)一般設(shè)在油箱外壁上，并靠近注油口，以便注油時(shí)觀測(cè)液面。

（4）、應(yīng)在油箱底部最低點(diǎn)設(shè)置放油塞，以便油箱清洗和油液更換，箱底應(yīng)朝向清洗孔和放油塞傾斜（通常為1/25～1/20），以促使沉積物（油泥或水）聚集到油箱中的最低點(diǎn)。油箱底至少離開地面150mm，以便于放油和搬運(yùn)。油箱應(yīng)設(shè)有支腳，支腳可以單獨(dú)制作后焊接在箱底邊緣上，也可以通過適當(dāng)增加兩側(cè)壁高度，以使其經(jīng)彎曲加工后兼作油箱支腳。如有必要，支腳上應(yīng)開設(shè)地腳螺釘用固定孔。支腳應(yīng)該有足夠大的面積，以便可以用墊片或楔鐵來調(diào)平。

（5）、在油液容量超過100L的油箱中應(yīng)設(shè)置內(nèi)部隔板，隔板要把系統(tǒng)回油區(qū)與吸油區(qū)隔開，并盡可能使油液在油箱內(nèi)沿著油箱壁環(huán)流。隔板缺口處要有足夠大的過流面積，使環(huán)流流速為0. 3～0. 6m/s。隔板下部應(yīng)開有缺口，以使吸油側(cè)的沉淀物經(jīng)此缺口至回油側(cè)，并經(jīng)放油口排出。為了有助于油液中的氣泡浮出液面，可在油箱內(nèi)謾置金屬除氣網(wǎng)，并傾斜10°～30°布置。

（6）、管路的配置。液壓系統(tǒng)的管路要進(jìn)入油箱并在油箱內(nèi)部終結(jié)。液壓泵的吸油管和系統(tǒng)的回油管要分別進(jìn)入由隔板隔開的吸油區(qū)和回油區(qū)，管端應(yīng)加工成朝向箱壁的45°斜口，以增加開口面積。為了防止空氣吸入（吸油管）或混入（回油管），以免攪動(dòng)或吸入箱底沉積物，管口上緣至少要低于最低液面75mm，管口下緣至少離開箱底最高點(diǎn)50mm。吸油管前必須安裝粗過濾器，以清除較大顆粒雜質(zhì)，保護(hù)液壓泵。

泄油管應(yīng)盡量單獨(dú)接入油箱并在液面以上終結(jié)。如果泄油管通人液面以下，要采取措施防止出現(xiàn)虹吸現(xiàn)象。

油管常從箱頂或箱壁穿過而進(jìn)入油箱，穿孔處要妥為密封。最好在接口處焊上高出箱頂20mm的凸臺(tái)，以免維修時(shí)箱頂上的污物落人油箱。如果油管從箱壁穿過而進(jìn)入油箱，除了妥為密封外，還要裝設(shè)截止閥以便于油箱外元件的維修。

（7）、油箱中如要安裝熱交換器等控溫、測(cè)溫裝置，則應(yīng)考慮其安裝位置。

（8）、油箱內(nèi)壁應(yīng)涂敷耐油防銹涂料或進(jìn)行噴塑處理。
