style="text-indent:25px">液壓站是由液壓泵、驅(qū)動用電動機、油箱、方向閥、節(jié)流閥、溢流閥等構(gòu)成的液壓源裝置或包括控制閥在內(nèi)的液壓裝置。按驅(qū)動裝置要求的流向、壓力和流量供油，適用于驅(qū)動裝置與液壓站分離的各種機械上，將液壓站與驅(qū)動裝置（油缸或馬達）用油管相連，液壓系統(tǒng)即可實現(xiàn)各種規(guī)定的動作。液壓站又稱液壓泵站，電機帶動油泵旋轉(zhuǎn)，泵從油箱中吸油后打油，將機械能轉(zhuǎn)化為液壓油的壓力能，液壓油通過集成塊（或閥組合）被液壓閥實現(xiàn)了方向、壓力、流量調(diào)節(jié)后經(jīng)外接管路傳輸?shù)揭簤簷C械的油缸或油馬達中，從而控制了液動機方向的變換、力量的大小及速度的快慢，推動各種液壓機械做功。液壓設(shè)備哪家好液壓站投入使用后一定要定期對各種閥、泵等元件進行檢查，發(fā)現(xiàn)有磨損的元件一定要及時更換掉。</p><div

style="text-indent:25px">液壓站在正式投入之前一般都要經(jīng)過沖洗。我們知道，液壓站的各個元件和管道在加工、運輸過程中，會有各種雜物進入系統(tǒng)，比如鐵屑、磨料和灰塵等，因此，一定要先做好清潔工作，將所有的液壓閥、管道和油箱洗干凈，必要的時候可以配合使用一些**的清潔劑去清洗。液壓站在使用過程中的定期檢查和維護是非常重要的，所以，在液壓站投入使用后一定要定期對各種閥、泵等元件進行檢查，發(fā)現(xiàn)有磨損的元件一定要及時更換掉。此外，密封件的檢查尤其重要，切不可有毛刺和飛邊。</p><p style="text-indent:25px">在液壓系統(tǒng)的組成部分中，各個組成部分的作用是不同的，動力元件的作用是將原動機的機械能轉(zhuǎn)換成液體的壓力能，指液壓系統(tǒng)中的油泵，它向整個液壓系統(tǒng)提供動力。液壓泵的結(jié)構(gòu)形式一般有齒輪泵、葉片泵、柱塞泵和螺桿泵。執(zhí)行元件(如液壓缸和液壓馬達)的作用是將液體的壓力能轉(zhuǎn)換為機械能，驅(qū)動負(fù)載作直線往復(fù)運動或回轉(zhuǎn)運動。控制元件(即各種液壓閥)在液壓系統(tǒng)中控制和調(diào)節(jié)液體的壓力、流量和方向。根據(jù)控制功能的不同，液壓閥可分為壓力控制閥、流量控制閥和方向控制閥。壓力控制閥包括溢流閥(安全閥)、減壓閥、順序閥、壓力繼電器等；流量控制閥包括節(jié)流閥、調(diào)整閥、分流集流閥等；方向控制閥包括單向閥、液控單向閥、梭閥、換向閥等。根據(jù)控制方式不同，液壓閥可分為開關(guān)式控制閥、定值控制閥和比例控制閥。輔助元件包括油箱、濾油器、冷卻器、加熱器、蓄能器、油管及管接頭、密封圈、快換接頭、高壓球閥、膠管總成、測壓接頭、壓力表、油位計、油溫計等。液壓油是液壓系統(tǒng)中傳遞能量的工作介質(zhì)，有各種礦物油、乳化液和合成型液壓油等幾大類。液壓站在使用過程中，引起人們注意的就是液壓油的使用，要結(jié)合實際情況正確選擇。</p><div

style="text-indent:25px">氣蝕現(xiàn)象的原因是：空穴伴隨著氣蝕發(fā)生，空穴中產(chǎn)生的氣泡中的氧也會腐蝕金屬元件的表面，我們把這種因發(fā)生空穴現(xiàn)象而造成的腐蝕叫氣蝕。部位：氣蝕現(xiàn)象可能發(fā)生在油泵、管路以及其他具有節(jié)流裝置的地方，特別是油泵裝置，這種現(xiàn)象較為常見。氣蝕現(xiàn)象是液壓系統(tǒng)產(chǎn)生各種故障的原因之一，特別在高速、高壓的液壓設(shè)備中更應(yīng)注意。液壓傳動系統(tǒng)由于其獨特的優(yōu)點，即具有普遍的工藝適應(yīng)性、優(yōu)良的控制性能和較低廉的成本，在各個領(lǐng)域中獲得愈來愈普遍的應(yīng)用。但由于客觀上元件、輔件質(zhì)量不穩(wěn)定和主觀上使用、維護不當(dāng)，且系統(tǒng)中各元件和工作液體都是在封閉油路內(nèi)工作，不象機械設(shè)備那樣直觀，也不象電氣設(shè)備那樣可利用各種檢測儀器方便地測量各種參數(shù),液壓設(shè)備中，*靠有限幾個壓力表、流量計等來指示系統(tǒng)某些部位的工作參數(shù)，其他參數(shù)難以測量，而且一般故障根源有許多種可能。液壓站以油箱的有效貯油量度及電機功率為主要技術(shù)參數(shù)。液壓系統(tǒng)閥組維修</p><p style="text-indent:25px">液壓系統(tǒng)的參數(shù)測量法是一種實用、新型的液壓系統(tǒng)故障診斷方法。浙江液壓閥塊</p><p style="text-indent:25px">只要測得液壓系統(tǒng)回路中所需任意點處工作參數(shù)，將其與系統(tǒng)工作的正常值相比較，即可判斷出系統(tǒng)工作參數(shù)是否正常，是否發(fā)生了故障以及故障的所在部位。液壓系統(tǒng)中的工作參數(shù)，如壓力、流量、溫度等都是非電物理量，用通用儀器采用間接測量法測量時，首先需利用物理效應(yīng)將這些非電量轉(zhuǎn)換成電量，然后經(jīng)放大、轉(zhuǎn)換和顯示等處理，被測參數(shù)則可用轉(zhuǎn)換后的電信號表示并顯示。由此可判斷液壓系統(tǒng)是否有故障。參數(shù)測量方法:1.測壓力，首先將檢測回路的軟管接頭與雙球閥三通螺紋接口旋緊接通。打開球閥，關(guān)死溢流閥，切斷回油通道，這時從壓力表上可直接讀出所測點的壓力值（為系統(tǒng)的實際工作壓力）。2.測流量和溫度——慢慢松開溢流閥7手柄，再關(guān)閉球閥。重新調(diào)整溢流閥，使壓力讀數(shù)為所測壓力值，此時流量計讀數(shù)即為所測點的實際流量值。同時溫度計上可顯示出油液溫度值。3.測轉(zhuǎn)速（速度）——不論泵、馬達或缸其轉(zhuǎn)速或速度*取決于兩個因素，即流量和它本身的幾何尺寸（排量或面積），所以只要測出馬達或缸的輸出流量（對泵為輸入流量），除以其排量或面積即得到轉(zhuǎn)速或速度值。浙江液壓閥塊</p><p
