style="text-indent:25px">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?/p><p
