Abstract

In order to raise the performance of tunnel drilling rig with all hydraulic head type, pump-controlled technology was applied in hydraulic system design. Working condition and basic circuit of hydraulic system were analyzed in this paper, at the base of which some disadvantages of the hydraulic system with valve-controlled technology were introduced. A comparison of characteristic and working condition was made between two pump-controlled technologies as load sensing and constant pressure output variable, The above two pump-controlled technologies were used in ZDY4000L track-mounted all hydraulic tunnel drilling rig, ZDY4000L type drilling rig was taken as an example to presents the distinct superiority of pump-controlled technology.
