【正文】 tion initial period. In recent years, along with the home production processing level39。s stability to be advantageous. ⑥ May control the support initially to support the strength well, obviously improves the supports and protections effect and the working surface management level. domestic and foreign application situation Overseas started in the 1970s to develop the development hydraulic support with the electrically controlled system, in the 80s entered the substantive application stage. To the 90s, the hydraulic support battery solution automatic control technology had been already mature, the operating performance and the reliability have been able to satisfy the operation requirements, thus develops very rapidly, bees produces the coal country synthesis to pick the working surface hydraulic support39。 Filter fineness 1 、 hydraulic support battery solution control system39。s foundations, elaborated systematically the support battery solution control system several aspects which displays in the domestic and foreign application condition and the present influence and the restriction domestic product support battery solution control system use and the performance. Proposed the formulation battery solution control system Guanyuan part manufacturing unified standards, the unification filtering element profession standard and the establishment battery solution control system working surface prevents the cleanliness control system39。 本科生畢業(yè)設(shè)計外文翻譯 學生姓名： xxx 學 號： xxx 專 業(yè)：機械設(shè)計制造及其自動化 班 級：機 053 班 指導教師： xxx In hydraulic support battery solution control system use question and countermeasure Zhang Mingli（張命林） (Zhengzhou coal mine mechanical group Limited liability pany Henan Zhengzhou 450013) Luo Yueyong（羅躍勇） (Beijing world Ma Ke battery solution control system Limited pany Beijing 100013) Abstract: To further display the support battery solution control system39。s importance which on own initiative and the passive filtration protection unifies, Establishes the perfect filtration protection system, further displays the domestically produced support battery solution control system performance. Key word: Hydraulic support。s superiority The hydraulic support battery solution control system is by electronic installations and the hydraulic circuit control portion and so on monolithic integrated circuit, sensor is posed, may need to control the hydraulic support automatic performance according to the production the system. ① Behind may fall the hydraulic support, to try to break up a fight, to rise the frame, the passage front part conveyer, to pull the conveyer, to receive protects helps the board, to extend protects helps the board, the atomization water spray and puts goes against movements and so on coal to change by the original manpower manual operation the battery solution automatic control, the sequencing to operate, Can match with the highly effective coal mining machine speeds up the working surface advancement speed, obviously enhances the mining coal working surface the production efficiency. ② May realize with machine the automated work, reduces t
