style="text-indent:25px">其實(shí)溢流閥分為直動(dòng)式跟先導(dǎo)式兩種的。直動(dòng)式結(jié)構(gòu)簡單，制造精度要求不高，成本低。阻力小，動(dòng)作靈敏。缺點(diǎn)就是壓力滯后比較嚴(yán)重，容易產(chǎn)生振動(dòng)，控制壓力受溢流量的影響較大，因此不能用在高壓和大流量的系統(tǒng)里，而先導(dǎo)式溢流閥則相反。溢流閥一般是用在并聯(lián)在系統(tǒng)的進(jìn)油旁路中起調(diào)壓、穩(wěn)壓與減壓作用；防止系統(tǒng)超載,保證安全。減壓閥分定值，定差和定比等三種；其中常見的就是定值減壓閥。如不指明通常說的減壓閥都是定值減壓閥。按安裝結(jié)構(gòu)可分為疊加式跟直裝式和管式減壓閥；一般情況下管式的比較少用。按工作形式可分為先導(dǎo)式跟直動(dòng)式兩種。</p><p style="text-indent:25px"> 拆卸前，應(yīng)將液壓油排放干凈，弄清液壓回路內(nèi)是否有強(qiáng)余的壓力，拆卸裝有蓄能器的液壓系統(tǒng)時(shí)，必須把蓄能器所有能量全部釋放，在拆卸挖掘機(jī)、裝載機(jī)和推土機(jī)等液壓系統(tǒng)時(shí)，必須將挖斗或鏟斗放到地面或用支柱支好，拆卸時(shí)不能亂敲亂打，以防損壞螺紋和密封表面，在拆卸缸時(shí)，不應(yīng)將活塞硬性從缸筒中打出，以免損壞表面，正確的方法是拆卸前依靠液壓油壓力使活塞移到缸筒的末端，然后進(jìn)行拆卸，拆下的零件的螺紋部分和密封面都要用膠布纏好，以防碰傷拆下的小零件要分別裝入塑料袋中保存；沒有必要，不要將多聯(lián)閥體拆成單體，拆卸油管時(shí)，要及時(shí)做好標(biāo)簽，以防裝錯(cuò)，拆下的油管要用清洗設(shè)備將管內(nèi)沖洗干凈，在兩端堵上塑料塞，拆下的油泵、油、馬達(dá)和閥的孔口，也要用塑料塞塞好或用膠布粘蓋好。油缸是工程機(jī)械主要部件。</p><div

style="text-indent:25px">液壓特點(diǎn)從能量傳遞方面看液壓技術(shù)大致處于機(jī)械式能.量傳遞和電氣式能.量傳遞之中間位置。從傳動(dòng)特性方面看機(jī)械傳動(dòng)和液力傳動(dòng)裝置可以說有固定的特性，與此相反，液壓傳動(dòng)裝置和電氣傳動(dòng)裝置相同，具有無級(jí)變速裝置的特性，除了恒功率外，還容易實(shí)現(xiàn)恒速和恒轉(zhuǎn)矩等特性。液壓技術(shù)的這種特點(diǎn)，一般可以歸納如下容易進(jìn)行無級(jí)變速，變速范圍廣，即能在很寬的范圍內(nèi)很容易地調(diào)節(jié)力與轉(zhuǎn)矩；控制性能好，即力、速度、位置等能以很高的響應(yīng)速度正確地進(jìn)行控制。另外，對(duì)于電氣，機(jī)械等其它的控制方式具有很好地適應(yīng)性，特別是和電氣信號(hào)處理相結(jié)合，可得.到優(yōu)良的響應(yīng)特性。動(dòng)作可靠，操作性能好；結(jié)構(gòu)和特性上具有適度的柔性；可以用標(biāo)準(zhǔn)元件構(gòu)成實(shí)現(xiàn)任意復(fù)雜機(jī)能的回路。液壓控制部分含有各種控制閥。安徽液壓系統(tǒng)設(shè)備廠家</p><p

style="text-indent:25px">液壓是由兩個(gè)大小不同的液缸組成的，在液缸里充滿水或油。充水的叫"水壓機(jī)"充油的稱油壓機(jī)。兩個(gè)液缸里各有一個(gè)可以滑動(dòng)的活塞，如果在小活塞上加一定值的壓力，根據(jù)帕斯卡定律，小活塞將這一壓力通過液體的壓力傳遞給大活塞，將大活塞頂上去。設(shè)小活塞的橫截面積是S1，加在小活塞上的向下的壓力是F1。于是，小活塞對(duì)液體的壓強(qiáng)為P=F1/SI，能夠大小不變地被液體向各個(gè)方向傳遞"。大活塞所受到的壓強(qiáng)必然也等于P。若大活塞的橫截面積是S2，壓強(qiáng)P在大活塞上所產(chǎn)生的向上的壓力F2=PxS2，截面積是小活塞橫截面積的倍數(shù)。從上式知，在小活塞上加一較小的力，則在大活塞上會(huì)有很大的力，為此用液壓機(jī)來壓制膠合板、榨油、提取重物、鍛壓鋼材等。液壓原理在一定的機(jī)械、電子系統(tǒng)內(nèi)，依靠液體介質(zhì)的靜壓力，完成積壓、傳遞、放大，實(shí)現(xiàn)機(jī)械功能的輕巧化、科學(xué)化。利用液壓原理，可以構(gòu)建液壓傳動(dòng)系統(tǒng)，也可以構(gòu)建液壓控制系統(tǒng)。金山區(qū)液壓系統(tǒng)維修</p></p><br
