常見(jiàn)液壓系統(tǒng)回路介紹及其工作原理
什么是液壓系統(tǒng)的回路?簡(jiǎn)單的說(shuō)它是由某些液壓元件和附件構(gòu)成并能完成某種特定功能的回路,液壓系統(tǒng)回路分類有保壓回路、卸荷回路、換向回路、鎖緊回路等等。
液壓系統(tǒng)換向回路原理:
適用于實(shí)現(xiàn)改變執(zhí)行元件運(yùn)動(dòng)方向的油路。簡(jiǎn)單的換向回路,可以通過(guò)采用各種換向閥或改變雙向變量液壓泵輸油方向來(lái)實(shí)現(xiàn)。其中換向閥有電磁閥、電液閥、手動(dòng)閥。又分爲(wèi)直流和交流兩種驅(qū)動(dòng)形式,它的特點(diǎn)是換向動(dòng)作快,有一定的沖擊力。但交流電磁閥不宜頻繁切換。
液壓系統(tǒng)卸荷回路原理:
1. 卸荷的作用:可以在不停電機(jī)、泵的情況下使系統(tǒng)沒(méi)有壓力,因爲(wèi)電機(jī)和泵在裝卸料的短時(shí)間內(nèi)停的話,就得頻繁停,對(duì)電機(jī)和泵是有害的。而不卸荷就帶負(fù)荷運(yùn)行,消耗電能就多了。
2. 洩荷原理:一般用卸荷閥來(lái)進(jìn)行卸荷;卸荷閥安裝在泵出口的支路上,可以是手動(dòng)的,可以是電動(dòng)的,打開它就讓泵油直接回油池了。也可以局部卸荷,隻要把卸荷閥安在局部油路的壓力管支路上即可。
液壓系統(tǒng)鎖緊回路原理:
第一種,用換向閥鎖緊的回路。因受換向閥內(nèi)洩漏的影響,采用換向閥鎖緊,鎖緊精度較低。
第二種,用單向閥鎖緊的回路。當(dāng)液壓泵停止工作時(shí),液壓缸活塞向右方向的運(yùn)動(dòng)被單向閥鎖緊,向左方向則可以運(yùn)動(dòng)。隻有當(dāng)活塞向左運(yùn)動(dòng)到極限位置時(shí),才能實(shí)現(xiàn)雙向鎖緊。這種回路的鎖緊精度也受換向閥內(nèi)洩漏量的影響。
第三種,用液控單向閥鎖緊的回路。當(dāng)換向閥處于中位時(shí),使液控單向閥進(jìn)油及控制油口與油箱相通,液控單向閥迅速封閉,液壓缸活塞向左方向的運(yùn)動(dòng)被液控單向閥鎖緊,向右方向則可以運(yùn)動(dòng),僅能實(shí)現(xiàn)單向鎖緊。
第四種,雙液控單向閥(液壓鎖)鎖緊回路。在工程機(jī)械液壓系統(tǒng)中常用此類鎖緊回路。當(dāng)三位四通電磁換向閥處于中位時(shí),兩個(gè)液控單向閥進(jìn)油及控制油口都與油箱相通,使兩個(gè)液控單向閥迅速關(guān)閉,可實(shí)現(xiàn)對(duì)液壓缸的雙向鎖緊。
