style="text-indent:25px">油缸是工程機(jī)械主要部件，傳統(tǒng)的加工方法是拉削缸體--精鏜缸體--磨削缸體。采用滾壓方法是:拉削缸體--精鏜缸體--滾壓缸體，工序是3部分，但時(shí)間上對(duì)比:磨削缸體1米大概在1-2天的時(shí)間，滾壓缸體1米大概在10-30分鐘的時(shí)間。投入對(duì)比:磨床或絎磨機(jī)，滾壓刀。滾壓后，孔表面粗糙度由幢滾前Ra3.2~6.3um減小為Ra0.4~0.8&um，孔的表面硬度提高約百分之30，缸筒內(nèi)表面疲勞強(qiáng)度提高百分之25。油缸使用壽命若只考慮缸筒影響，提高2~3倍，鏜削滾壓工藝較磨削工藝效率提高3倍左右。以上數(shù)據(jù)說(shuō)明，滾壓工藝是高.效的，能較大提高缸筒的表面質(zhì)量。油缸經(jīng)過(guò)滾壓后，表面沒(méi)有鋒利的微小刃口，長(zhǎng)時(shí)間的運(yùn)動(dòng)摩擦也不會(huì)損傷密封圈或密封件，這點(diǎn)在液壓行業(yè)特別重要。上海液壓系統(tǒng)維修液壓源含有液壓泵、電動(dòng)機(jī)和液壓輔助元件。</p><div

style="text-indent:25px">液壓系統(tǒng)的工作壓力取決于負(fù)載的大小。執(zhí)行元件所受到的總負(fù)載，即總阻力包括工作負(fù)載、執(zhí)行元件由于自重和機(jī)械摩擦所產(chǎn)生的摩擦阻力，以及油流在管路中流動(dòng)時(shí)所產(chǎn)生的沿程阻力和局部阻力等。由于負(fù)載使液流受到阻礙而產(chǎn)生一定的壓力，并且負(fù)載越大，油壓越高，但較高工作壓力必須有一定的限制。為使系統(tǒng)保持一定的工作壓力，或在一定的壓力范圍內(nèi)工作，或能在幾種不同壓力下工作，因此要調(diào)整和控制整個(gè)系統(tǒng)的壓力。壓力控制回路就是利用壓力控制元件來(lái)控制整個(gè)液壓系統(tǒng)或局部油路的工作壓力，以滿足執(zhí)行元件對(duì)力或力矩的要求，或者達(dá)到合理利用功率、保證系統(tǒng)安全等目的。</p><p style="text-indent:25px">液壓系統(tǒng)插裝閥的優(yōu)點(diǎn)可實(shí)現(xiàn)大功率控制，壓力損失小，發(fā)熱小。這一方面由于二通插裝閥的使用減少了許多管路，沿程損失小；另一方面單個(gè)插裝閥單元(邏輯閥單元)較之同口徑的常規(guī)閥壓力損失較大降低；而且能通過(guò)常規(guī)閥無(wú)法比擬的大流量，常規(guī)液壓閥根本就無(wú)法有這種大流量(大功率)的產(chǎn)品。這種通流能力是常規(guī)閥不可想象的，所以插裝閥適用于高壓大流量大功率的液壓系統(tǒng)。插裝閥主要由邏輯單元(插裝件)構(gòu)成，它現(xiàn)已標(biāo)準(zhǔn)化，可組織專門生產(chǎn)廠家生產(chǎn)，利于批量生產(chǎn)，可降低成本和能專業(yè)化生產(chǎn)，從而提高產(chǎn)品質(zhì)量，設(shè)計(jì)時(shí)也可方便選用。靜密封件在剛性固定表面之間防止油液外泄。</p><div
