Drilling machine hydraulic system is directly responsible for the control and transmission system, directly affect the system performance is the key technology of drilling rig. This paper describes the design of the hydraulic system of horizontal directional drilling process. First, more detailed description of the horizontal directional cobalt machine works, the performance indicators, design parameters, structure, and analyzes the various agencies working conditions and load conditions, for the next design of the hydraulic system design basis. Then the previous results of the analysis of the hydraulic system design, and a reasonable choice of hydraulic ponents of each subsystem, and finally, checking the performance of the hydraulic system. This design allows the hydraulic system of the engine hydraulic system39。 首先 ，比較詳盡地描述了水平定向 鉆 機(jī)的工作原理、各項性能指標(biāo)、設(shè)計參數(shù)、結(jié)構(gòu)組成，同時分析了各機(jī)構(gòu)的工況和負(fù)載情況，為下一步液壓系統(tǒng)的設(shè)計提供設(shè)計依據(jù) 。 在當(dāng)今中國基礎(chǔ)設(shè)施建設(shè)如火如荼的大環(huán)境下，擁有廣泛的市場前景 。 目前，對比與國外先進(jìn)的水平定向鉆機(jī)研發(fā)水平，我國的鉆機(jī)研發(fā)還處于一個比較落后的水平，因此加快水平定向鉆機(jī)的研發(fā)工作具有明顯的社會意義和經(jīng)濟(jì)意義 。然后 根據(jù)前面分析的結(jié)果， 對液壓系統(tǒng)進(jìn)行設(shè)計，并合理選擇各子系統(tǒng)的液壓元件，最后，進(jìn)行液壓系統(tǒng)的性能驗算。s performance to good condition, engine power utilization, rig hydraulic system transmission efficiency and higher operating efficiency.
