style="text-indent:25px">液壓系統(tǒng)的注意事項(xiàng)：有一點(diǎn)機(jī)械常識(shí)的人都知道，能量會(huì)互相轉(zhuǎn)換的，而把這個(gè)知識(shí)運(yùn)用到液壓系統(tǒng)上解釋液壓系統(tǒng)的功率損失是再好不過(guò)了，液壓系統(tǒng)功率一方面會(huì)造成能量上的損失，使系統(tǒng)的總效率下降，另一方面，損失掉的這一部分能量將會(huì)轉(zhuǎn)變成熱能，使液壓油的溫度升高，油液變質(zhì)，導(dǎo)致液壓設(shè)備出現(xiàn)故障。因此，設(shè)計(jì)液壓系統(tǒng)時(shí)，在滿足使用要求的前提下，還應(yīng)充分考慮降低系統(tǒng)的功率損失。從動(dòng)力源——泵的方面來(lái)考慮，考慮到執(zhí)行器工作狀況的多樣化，有時(shí)系統(tǒng)需要大流量，低壓力；有時(shí)又需要小流量，高壓力。所以選擇限壓式變量泵為宜，因?yàn)檫@種類型的泵的流量隨系統(tǒng)壓力的變化而變化。當(dāng)系統(tǒng)壓力降低時(shí)，流量比較大，能滿足執(zhí)行器的快速行程。當(dāng)系統(tǒng)壓力提高時(shí)流量又相應(yīng)減小，能滿足執(zhí)行器的工作行程。這樣既能滿足執(zhí)行器的工作要求，又能使功率的消耗比較合理。一個(gè)完整的液壓系統(tǒng)由五個(gè)部分組成，即動(dòng)力元件、執(zhí)行元件、控制元件、輔助元件和液壓油。液壓拉伸器</p><p style="text-indent:25px">液壓試驗(yàn)臺(tái)使用前檢查：檢查油泵、電機(jī)轉(zhuǎn)向是否正確，必要時(shí)予以調(diào)整。液壓拉伸器</p><p style="text-indent:25px">液壓系統(tǒng)的動(dòng)力元件：動(dòng)力元件的作用是將原動(dòng)機(jī)的機(jī)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(gè)液壓系統(tǒng)提供動(dòng)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。液壓系統(tǒng)的執(zhí)行元件：執(zhí)行元件(如液壓缸和液壓馬達(dá))的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能，驅(qū)動(dòng)負(fù)載作直線往復(fù)運(yùn)動(dòng)或回轉(zhuǎn)運(yùn)動(dòng)。液壓系統(tǒng)的控制元件：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。液壓拉伸器</p></p><br
