液壓系統(tǒng)故障診斷之故障參數(shù)、專用設(shè)備、診斷方法

隨著工業(yè)技術(shù)的不斷發(fā)展，液壓系統(tǒng)維修除依靠固有的工作經(jīng)驗(yàn)外，越來越多的維修人員開始著手專用的測試儀器與設(shè)備，本文以故障參數(shù)、專用設(shè)備與診斷方法這三點(diǎn)分別予以講解。

一、故障參數(shù)

液壓系統(tǒng)故障的主要參數(shù)包括壓力、流量、溫度、執(zhí)行機(jī)構(gòu)（液壓元件）的運(yùn)行速度、噪聲、油液狀態(tài)（受污染程度、黏度等）及外部洩露等，針對不同參數(shù)測量時(shí)，應(yīng)根據(jù)現(xiàn)場條件（室內(nèi)或室外）和控制精度的要求，選擇相對應(yīng)的測試儀表。

①測壓力：通?？煞譅?wèi)普通壓力表、標(biāo)準(zhǔn)壓力表、電接點(diǎn)壓力表與應(yīng)變式壓力傳感器（可測量液壓管路的瞬時(shí)壓力）；

②測流量：通?？煞譅?wèi)橢圓齒輪流量計(jì)、渦輪流量計(jì)、電遠(yuǎn)傳浮子流量計(jì)與計(jì)量油馬達(dá)等；

③測溫度：通?？煞譅?wèi)普通水銀溫度計(jì)（測油箱油溫）、電接點(diǎn)水銀溫度計(jì)壓力式溫度計(jì)與電阻式溫度計(jì)（能測量液壓元件的表面溫度）等；

④測油液狀態(tài)：通?？煞譅?wèi)顯微鏡、光學(xué)比較儀、粒子計(jì)數(shù)器與粘度計(jì)等；

⑤測噪聲：通?？煞譅?wèi)聲級(jí)器和譜頻分析器。

二、專用設(shè)備

爲(wèi)了迅速判斷具體的故障原因并及時(shí)排除，國內(nèi)外先后研制出一系列液壓故障測試儀器與設(shè)備，部分設(shè)備如下：

①手提式液壓測試器：這是一種用于測試液壓系統(tǒng)故障部位的機(jī)械裝置，由流量計(jì)、壓力表與溫度指示表等組成，具體作用爲(wèi)測試液壓系統(tǒng)的流量、壓力與溫度等出現(xiàn)的異常故障，其接入管路中的接法可分爲(wèi)旁通測試與直通測試兩種。

I. 旁通測試

系統(tǒng)的壓力油管應(yīng)接到測試器的進(jìn)油口處，回油管需接到測試器的出油口處，測試器上的一隻控制閥主要用于調(diào)節(jié)和選擇不同的壓力范圍數(shù)值；

II.直通測試

將測試器串接于系統(tǒng)的壓力油管上，使之成爲(wèi)液壓系統(tǒng)的一個(gè)臨時(shí)組件，當(dāng)系統(tǒng)正常工作時(shí)，可直接測得流量、壓力、溫度的具體數(shù)據(jù)，以判斷系統(tǒng)是否正常；

IIII.方法比較

通常測試時(shí)大多選用直通式，旁通式不適用于做整體測試的封閉型液壓系統(tǒng)，測試時(shí)需搭載上分隔組件。

②采用“T”型接頭（三通接頭）：若不測試，需用堵頭將接頭一端堵住；若測試中，需打開并接入測試油管，實(shí)質(zhì)上類似于旁通測試。

I. 當(dāng)機(jī)械正常運(yùn)轉(zhuǎn)時(shí)，通常會(huì)考慮采用這種“T”型接頭測試；

II.其優(yōu)勢在于不會(huì)影響到系統(tǒng)的正産工作，且適用于預(yù)防性維護(hù)；

III.現(xiàn)在新型T型接頭一般采用磁性旋塞，混入油液中的金屬微粒通過接頭被吸附于磁性旋塞上，若拆卸旋塞予以測試，則可判斷出液壓油的受污染程度；

③液壓系統(tǒng)維修車：這種維修車主要用于軍事工業(yè)，方便在現(xiàn)場盡快修複損壞的工程機(jī)械液壓系統(tǒng)；

④油泵故障診斷器：該設(shè)備可對油泵從外部直接予以故障診斷，且能初步推斷出油泵的剩馀使用壽命。

三、診斷方法

故障診斷的方法種類多樣，小編就較常見的幾大類與大家分享。

一、“四覺”診斷法：所謂四覺，即觸覺、視覺、聽覺與嗅覺這四種，如果故障處于初期階段，可通過這四覺直接判斷并予以處理，這也是目前現(xiàn)場獲得故障信息的簡單途徑；

二、順序推理檢測法：這種診斷法要求主機(jī)停止工作，根據(jù)診斷出的具體故障位置和涉及的故障范圍（局部或全系統(tǒng)問題），將故障盡量縮小至最小范圍，隨后按順序分析法逐一推理，以判斷故障所在；

三、采用故障測試器的診斷：旁通測試和直通測試

當(dāng)液壓系統(tǒng)的故障現(xiàn)象是外負(fù)載加大時(shí)，油缸的動(dòng)作將趨于緩慢，若想盡快查找出故障所在并加以處理，需進(jìn)行全面測試組成系統(tǒng)的所有相關(guān)元件，用上述的測試器逐一檢測。

（1）旁通測試：先測溢流閥，后測油泵及方向閥

①溢流閥的檢測：爲(wèi)防止油管被甩出，需按指定油管油路連接測試器，回油管處可用尼龍繩將其扎緊于油箱上。

具體檢測過程如下：

I. 先將測試器的控制閥置于空載位置；

II. 啓動(dòng)電機(jī)以額定轉(zhuǎn)速運(yùn)轉(zhuǎn)；

III. 在流量計(jì)的流量讀數(shù)未歸零時(shí)，緩慢旋緊測試器的控制閥，壓力表讀數(shù)應(yīng)爲(wèi)該液壓系統(tǒng)溢流閥的固定值；

IV. 按測試要求調(diào)節(jié)系統(tǒng)的溢流閥（調(diào)節(jié)后，應(yīng)重新測試）；

V. 若壓力表指針出現(xiàn)跳動(dòng)，即說明油泵吸油側(cè)存在洩漏問題，需對其先予以修複，避免出現(xiàn)氣蝕現(xiàn)象；

VI. 在壓力值歸零前，流經(jīng)溢流閥的流量應(yīng)等同于油泵的額定流量；

VII.在溢流閥完全打開前，若測試器流量計(jì)所顯示的數(shù)值出現(xiàn)變化，即說明溢流閥存在洩漏問題，此時(shí)應(yīng)全面檢查閥芯與閥座，觀察閥座部位是否有磨損或傷痕，重新測試前，應(yīng)及時(shí)修複或更換。

②油泵的檢測：按要求接好測試器后，油泵與系統(tǒng)將隔開，且不再受溢流閥的控制，因此，其工作壓力不得超過系統(tǒng)最大工作壓力值。

具體測試過程如下：

I.打開測試器的控制閥并啓動(dòng)電機(jī)，使其在額定轉(zhuǎn)速下運(yùn)轉(zhuǎn)；

II.觀察并記錄下測試器在空載時(shí)的流量讀數(shù)，接著緩慢關(guān)閉測試器的控制閥，使測試壓力可逐步上升至系統(tǒng)的額定壓力；

III.若此時(shí)流量計(jì)上的讀數(shù)減少25％，即說明油泵存在故障問題，若流量降低至50％，則可初步斷定液壓系統(tǒng)的故障是油泵所引起；

IV.若壓力表的指針出現(xiàn)跳動(dòng)，即說明油泵的吸油側(cè)存在洩漏問題，爲(wèi)防止進(jìn)一步出現(xiàn)氣蝕現(xiàn)象，需對油泵的吸油側(cè)及時(shí)檢查表并修複。

③方向閥的測試：按管路要求連接旁通測試器，并將回油管扎緊于油箱上。

具體檢測過程如下：

I.打開測試器的控制閥并啓動(dòng)電機(jī)，以額定轉(zhuǎn)速進(jìn)行運(yùn)轉(zhuǎn)；

II.通過方向控制閥的油液需經(jīng)過測試器才可流回油箱；

III.爲(wèi)確保測試器安全使用，從方向控制閥上拆下油管接頭時(shí)，需將有機(jī)械運(yùn)動(dòng)的部件全鎖緊；

IV.記錄下空載時(shí)的流量度數(shù)，若測得流量值近似于油泵流量，即證明液壓系統(tǒng)正常，故障問題可確定不在前端部分；

V.在壓力達(dá)到比系統(tǒng)的額定溢流壓力稍低（通常爲(wèi)3×10～4×10Pa）前，應(yīng)將測試器的加載閥（壓力控制閥）緩慢關(guān)閉；

VI.在此壓力下，觀察并記錄其流量值。若該流量與空載流量基本相同，說明該方向閥性能基本良好，若流量損失較大，及證明方向閥存在一定問題需及時(shí)維修，且可能存在嚴(yán)重的洩漏問題。當(dāng)修複方向控制閥時(shí)，應(yīng)及時(shí)洩掉其壓力再進(jìn)行操作，以免發(fā)生意外。

（2）直通測試

該測試包括溢流閥故障、油泵故障、方向控制閥故障、油泵及其他元件故障共四種，針對具體情況予以對應(yīng)處理。
