style="text-indent:25px">避免液壓系統(tǒng)功率損失：如果執(zhí)行器具有調(diào)速的要求，那么在選擇調(diào)速回路時(shí)，既要滿足調(diào)速的要求，又要盡量減少功率損失。常見的調(diào)速回路主要有：節(jié)流調(diào)速回路，容積調(diào)速回路，容積節(jié)流調(diào)速回路。其中節(jié)流調(diào)速回路的功率損失大，低速穩(wěn)定性好。而容積調(diào)速回路既無溢流損失，也無節(jié)流損失，效率高，但低速穩(wěn)定性差。如果要同時(shí)滿足兩方面的要求，可采用差壓式變量泵和節(jié)流閥組成的容積節(jié)流調(diào)速回路，并使節(jié)流閥兩端的壓力差盡量小，以減小壓力損失。合理選擇液壓油。液壓油在管路中流動(dòng)時(shí)，將呈現(xiàn)出黏性，而黏性過高時(shí)，將產(chǎn)生較大的內(nèi)摩擦力，造成油液發(fā)熱，同時(shí)增加油液流動(dòng)時(shí)的阻力。當(dāng)黏性過低時(shí)，易造成泄漏，將降低系統(tǒng)容積效率，因此，一般選擇黏度適宜且黏溫特性比較好的油液。另外，當(dāng)油液在管路中流動(dòng)時(shí)，還存在著沿程壓力損失和局部壓力損失，因此設(shè)計(jì)管路時(shí)盡量縮短管道，同時(shí)減少?gòu)澒堋３Ｖ菀簤合到y(tǒng)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)。</p><div

style="text-indent:25px">液壓系統(tǒng)的安裝：液壓系統(tǒng)安裝質(zhì)量的好壞是關(guān)系到液壓系統(tǒng)能否可靠工作的關(guān)鍵。必須科學(xué)、正常、合理地完成安裝過程中的每個(gè)環(huán)節(jié)，才能使液壓系統(tǒng)能夠正常運(yùn)行，充分發(fā)揮其效能。安裝前的準(zhǔn)備工作： 1）明確安裝現(xiàn)場(chǎng)施工程序及施工進(jìn)度方案。 2）熟悉安裝圖樣，掌握設(shè)備分布及設(shè)備基礎(chǔ)情況。 3）落實(shí)好安裝所需人員、機(jī)械、物資材料的準(zhǔn)備工作。 4）做好液壓設(shè)備的現(xiàn)場(chǎng)交貨驗(yàn)收工作，根據(jù)設(shè)備清單進(jìn)行驗(yàn)收。通過驗(yàn)收掌握設(shè)備名稱、數(shù)量、隨機(jī)備件、外觀質(zhì)量等情況，發(fā)現(xiàn)問題及時(shí)處理。 5）根據(jù)設(shè)計(jì)圖紙對(duì)設(shè)備基礎(chǔ)和預(yù)埋件進(jìn)行檢查，對(duì)液壓設(shè)備地腳尺寸進(jìn)行復(fù)核，對(duì)不符合要求的地方進(jìn)行處理，防止影響施工進(jìn)度。液壓系統(tǒng)由信號(hào)控制和液壓動(dòng)力兩部分組成。</p><div
