液壓系統(tǒng)溢流閥故障診斷與解決大總結(jié)

溢流閥的故障表現(xiàn)形式衆(zhòng)多，一般可歸納爲(wèi)噪聲與振動(dòng)、壓力波動(dòng)、壓力調(diào)整無(wú)效以及油液洩露共四大類(lèi)，接下來(lái)針對(duì)故障診斷與解決方法給大家做個(gè)總結(jié)，下面一起來(lái)看看吧！

（一）噪聲與振動(dòng)

該問(wèn)題在溢流閥中尤爲(wèi)常見(jiàn)，産生噪聲的因素衆(zhòng)多，包括壓力不均勻、空穴現(xiàn)象、液壓沖擊與機(jī)械噪聲四種，假如使用的是高壓大流量型溢流閥，振動(dòng)與噪聲問(wèn)題將更劇烈。

①壓力不均勻

當(dāng)溢流閥處于高壓下溢流，導(dǎo)閥的軸向開(kāi)口相對(duì)較小，數(shù)據(jù)一般爲(wèi)0.003～0.006cm，這使得油液過(guò)流的面積也相對(duì)偏小，流速卻可達(dá)200m/s，從而容易引發(fā)壓力分布不均，導(dǎo)緻錐閥徑向力不平衡以産生振動(dòng)。此外，當(dāng)出現(xiàn)錐閥和錐閥座加工時(shí)出現(xiàn)橢圓問(wèn)題、導(dǎo)閥口的污物黏著或調(diào)壓彈簧變形等也會(huì)引起錐閥的振動(dòng)，因此通常認(rèn)爲(wèi)導(dǎo)閥是形成噪聲的震源所在。想要解決這一問(wèn)題，就需要加大對(duì)錐閥工藝的監(jiān)管，保持元件的清潔度，定時(shí)檢查若發(fā)現(xiàn)問(wèn)題應(yīng)立即解決。

②空穴現(xiàn)象

空穴現(xiàn)象在溢流閥故障中較爲(wèi)常見(jiàn)，其表現(xiàn)爲(wèi)空氣被吸入油液中，溶解的部分空氣析出形成氣泡，這些氣泡在低壓區(qū)時(shí)體積較大，當(dāng)油液流入高壓區(qū)時(shí)氣泡因壓縮而變小甚至消失，若氣泡處于高壓區(qū)，流向低壓區(qū)的過(guò)程中體積會(huì)突然增大，體積上的變化促成噪聲的産生。這一過(guò)程時(shí)間極短，會(huì)進(jìn)一步引起局部液壓沖擊而産生振動(dòng)，如果溢流閥的導(dǎo)閥口和主閥口口徑較小，油液流動(dòng)和壓力數(shù)值變化偏大，這就容易出現(xiàn)空穴現(xiàn)象，進(jìn)而産生噪聲與振動(dòng)。解決這一問(wèn)題的辦法即是適當(dāng)降低油壓以控制流速，或挑選閥口更大的溢流閥。

③液壓沖擊

當(dāng)溢流閥處于卸荷狀態(tài)時(shí)，會(huì)因液壓回路的壓力驟降而出現(xiàn)噪聲，其原因在于溢流閥的卸荷時(shí)間較短，油液流速急劇變化時(shí)會(huì)引起壓力突變，從而造成壓力波的沖擊。這種壓力波本身産生的噪聲很小，但隨著油液傳入系統(tǒng)內(nèi)容易與機(jī)械部件引發(fā)共振，從而加大了振動(dòng)和噪聲的增強(qiáng)。解決這一問(wèn)題的辦法在于卸荷過(guò)程中，盡量降低油壓以控制流速，可通過(guò)聽(tīng)覺(jué)判斷系統(tǒng)內(nèi)的噪聲情況予以調(diào)整。

④機(jī)械噪聲

這一現(xiàn)象一般是因裝配或維護(hù)不當(dāng)所導(dǎo)緻，主要表現(xiàn)爲(wèi)：

I. 滑閥和閥孔因配合過(guò)緊或過(guò)松産生噪聲，過(guò)緊時(shí)滑閥會(huì)移動(dòng)困難，引起振動(dòng)與噪聲，過(guò)松時(shí)會(huì)因間隙將過(guò)大加劇洩露，從而引起振動(dòng)和噪聲。其解決的途徑在于合理調(diào)節(jié)滑閥與閥控的間距；

II.彈簧剛度不夠，易産生彎曲變形，液動(dòng)力會(huì)引起彈簧自振，當(dāng)彈簧振動(dòng)頻率與系統(tǒng)振動(dòng)頻率相同時(shí)，則會(huì)出現(xiàn)共振現(xiàn)象。其解決的途徑在于及時(shí)更換彈簧；

III.壓力調(diào)節(jié)后，一定要將松動(dòng)的螺母擰緊，避免進(jìn)一步出現(xiàn)振動(dòng)或噪聲；

IV.當(dāng)油口油路中有空氣存在時(shí)，也容易産生噪聲，其解決途徑在于先排除油口和油路中的空氣，進(jìn)而加大密封；

V.當(dāng)溢流閥與其他元件産生共振時(shí)，會(huì)造成振動(dòng)與噪聲的加劇。其解決途徑在于及時(shí)檢查各元件的安裝與管件連接處有無(wú)松動(dòng)，一旦存在問(wèn)題便立即處理。

（二）壓力波動(dòng)

該故障在溢流閥中容易出現(xiàn)，其既可能是自身問(wèn)題，也可能是油泵與系統(tǒng)的連帶影響，自身引起波動(dòng)的主要原因如下：

①控制閥芯的彈簧剛度不夠，或彈簧彎曲變形，無(wú)法維持穩(wěn)定的工作壓力，其解決辦法爲(wèi)更換彈簧；

②油液因污染嚴(yán)重，阻尼孔被堵塞，導(dǎo)緻滑閥移動(dòng)困難，其解決辦法爲(wèi)經(jīng)常檢查油液的受污染度，必要時(shí)考慮換油和疏通阻尼孔；

③錐閥和鋼球與閥座間的配合不佳，造成原因可能是由于污物卡住或磨損，其解決辦法爲(wèi)清除污物并修磨閥座，若磨損嚴(yán)重則更換錐閥（或鋼球），若壓力波動(dòng)較大，采取各種辦法均無(wú)法解決問(wèn)題時(shí)，可考慮對(duì)錐閥或鋼球輕輕敲打，隨之壓力波動(dòng)也可能相應(yīng)降低；

④滑閥動(dòng)作不靈活，造成原因可能是滑閥表面被拉傷、閥孔碰傷、滑閥被污物卡住或滑閥與孔配合過(guò)緊等，解決辦法爲(wèi)對(duì)受損處予以清洗和修磨，若嚴(yán)重至無(wú)法修磨，則可考慮更換滑閥。

（三）壓力調(diào)整無(wú)效

這種情況一般是指無(wú)壓力、壓力調(diào)不上去或壓力提升過(guò)快，通常調(diào)整液壓系統(tǒng)壓力的正確方法是首先將溢流閥全打開(kāi)（即彈簧無(wú)壓縮），啓動(dòng)油泵后慢慢旋緊調(diào)壓按鈕（彈簧壓縮量逐漸增大），壓力隨之穩(wěn)步上升，若油泵在啓動(dòng)后壓力迅速上升且無(wú)法停止，則可判斷是溢流閥尚未打開(kāi)或出現(xiàn)故障。調(diào)壓無(wú)效的主要原因如下：

①?gòu)椈蓳p壞、斷裂或漏裝，其解決辦法爲(wèi)重裝彈簧或予以更換；

②滑閥配合過(guò)緊或被污物卡住造成調(diào)整壓力上升，其解決辦法爲(wèi)檢查。清洗并研修，使滑閥可在孔內(nèi)靈活移動(dòng)，若油液污染較爲(wèi)嚴(yán)重，則建議考慮及時(shí)更換油液；

③錐閥或鋼球漏裝，使滑閥失去控制，導(dǎo)緻調(diào)壓無(wú)效，其解決辦法爲(wèi)直接補(bǔ)裝錐閥或鋼球；

④阻尼孔堵塞，導(dǎo)緻滑閥失去控制作用，其解決辦法爲(wèi)清洗阻尼孔，若油液也存在嚴(yán)重?zé)o法，則考慮更換油液；

⑤進(jìn)油口和出油口裝反，其解決辦法爲(wèi)根據(jù)油液流向及時(shí)糾正。

（四）油液洩露

這一故障可分爲(wèi)內(nèi)洩露與外洩露兩類(lèi)，外洩露一般會(huì)對(duì)環(huán)境造成污染，故易被發(fā)現(xiàn)，但內(nèi)洩露由于情況負(fù)責(zé)則不容易被發(fā)現(xiàn)，存在該問(wèn)題時(shí)往往會(huì)引起噪聲增大和明顯的壓力波動(dòng)問(wèn)題。

常見(jiàn)的外洩露部位與具體原因如下：

①管接頭未擰緊或接觸不良，其解決辦法爲(wèi)檢查管接頭并擰緊；

②相關(guān)結(jié)合面上的紙墊被沖破，或銅墊完全失效，其解決辦法爲(wèi)及時(shí)更換紙墊或銅墊，并確認(rèn)系統(tǒng)連接處的密封性是否良好。

常見(jiàn)的內(nèi)洩露部位與具體原因如下：

①錐閥或鋼球與閥座接觸不良，造成原因可能是因爲(wèi)磨損或被污物卡住，其解決辦法爲(wèi)修磨閥座，并考慮更換鋼球；

②滑閥與閥體配合間隙過(guò)大，其解決辦法爲(wèi)對(duì)間隙予以調(diào)整或考慮更換滑閥。
