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)行機構(gòu)(液壓元件)的運行速度、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,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??煞譅懫胀▔毫Ρ怼藴蕢毫Ρ?、電接點壓力表與應(yīng)變式壓力傳感器(可測量液壓管路的瞬時壓力);

②測流量:通??煞譅憴E圓齒輪流量計、渦輪流量計、電遠傳浮子流量計與計量油馬達等;

③測溫度:通??煞譅懫胀ㄋy溫度計(測油箱油溫)、電接點水銀溫度計壓力式溫度計與電阻式溫度計(能測量液壓元件的表面溫度)等;

④測油液狀態(tài):通??煞譅戯@微鏡、光學(xué)比較儀、粒子計數(shù)器與粘度計等;

⑤測噪聲:通??煞譅懧暭壠骱妥V頻分析器。

二、專用設(shè)備

爲了迅速判斷具體的故障原因并及時排除,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)故障部位的機械裝置,由流量計、壓力表與溫度指示表等組成,具體作用爲測試液壓系統(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,使之成爲液壓系統(tǒng)的一個臨時組件,當(dāng)系統(tǒng)正常工作時,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??;若測試中,需打開并接入測試油管,實質(zhì)上類似于旁通測試。

I. 當(dāng)機械正常運轉(zhuǎn)時,通常會考慮采用這種“T”型接頭測試;

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

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)象是外負載加大時,油缸的動作將趨于緩慢,若想盡快查找出故障所在并加以處理,需進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. 啓動電機以額定轉(zhuǎn)速運轉(zhuǎn);

III. 在流量計的流量讀數(shù)未歸零時,緩慢旋緊測試器的控制閥,壓力表讀數(shù)應(yīng)爲該液壓系統(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,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電機,使其在額定轉(zhuǎn)速下運轉(zhuǎn);

II.觀察并記錄下測試器在空載時的流量讀數(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.若此時流量計上的讀數(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,即說明油泵的吸油側(cè)存在洩漏問題,爲防止進一步出現(xiàn)氣蝕現(xiàn)象,需對油泵的吸油側(cè)及時檢查表并修複。

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電機,以額定轉(zhuǎn)速進行運轉(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.爲確保測試器安全使用,從方向控制閥上拆下油管接頭時,需將有機械運動的部件全鎖緊;

IV.記錄下空載時的流量度數(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.在壓力達到比系統(tǒng)的額定溢流壓力稍低(通常爲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維修,且可能存在嚴重的洩漏問題。當(dāng)修複方向控制閥時,應(yīng)及時洩掉其壓力再進行操作,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。
