【正文】 學(xué)士學(xué)位畢業(yè) 設(shè)計(jì) 專(zhuān)用銑床液壓系統(tǒng)設(shè)計(jì) 學(xué) 生 姓 名： 乾久久 學(xué) 號(hào)： XXXX 指 導(dǎo) 教 師： 顏如玉 所 在 學(xué) 院： 工程學(xué)院 專(zhuān) 業(yè)： 機(jī)械設(shè)計(jì)制造及其自動(dòng)化 中 國(guó) 大慶 2021 年 6 月 黑龍江八一農(nóng)墾大學(xué)本科畢業(yè)設(shè)計(jì) I 摘要 液壓系統(tǒng)是以電機(jī)提供動(dòng)力基礎(chǔ)，使用液壓泵將機(jī)械能轉(zhuǎn)化為壓力，推動(dòng)液壓油。通過(guò)控制各種閥門(mén)改變液壓油的流向，從而推動(dòng)液壓缸做出不同行程、不同方向的動(dòng)作。完成各種設(shè)備不同的動(dòng)作需要。液壓系統(tǒng)已經(jīng)在各個(gè)工業(yè)部門(mén) 及農(nóng)林牧漁等許多部門(mén)得到愈來(lái)愈廣泛的應(yīng)用，而且愈先進(jìn)的設(shè)備，其應(yīng)用液壓系統(tǒng)的部分就愈多。所以像我們這樣的大學(xué)生學(xué)習(xí)和親手設(shè)計(jì)一個(gè)簡(jiǎn)單的液壓系統(tǒng)是非常有意義的。 關(guān)鍵詞 ：液壓傳動(dòng)、穩(wěn)定性、液壓系統(tǒng) 黑龍江八一農(nóng)墾大學(xué)本科畢業(yè)設(shè)計(jì) II Abstract Hydraulic system is powered motor basis, the use of hydraulic pump will translate into pressure on the mechanical energy, promote the hydraulic oil. Through various control valves to change the flow of hydraulic oil, thus promoting the hydraulic cylinders made of different itinerary, the movements in different directions. All kinds of different equipment to plete the actions required. Hydraulic system has been in various industrial sectors and agriculture, forestry, animal husbandry and fisheries, and many other departments are more widely used, and more advanced equipment, its application on the part of the hydraulic system more. So students like us to study and personally designed a simple hydraulic system is very meaningful.
