Technology of load-sensitivity used in the hydraulic system of an all-hydraulic core rig

  • Published:
Journal of Coal Science and Engineering (China)

Abstract

The existing hydraulic system always have problems of temperature rise, running stability and anti-interference of the implementation components, reliability of hydraulic components, maintenance difficulties, and other issues. With high efficiency, energy saving, reliability, easy operating, stable running, anti-interference ability, and other advantages, the load-sensitive hydraulic system is more suitable for coal mine all-hydraulic core rig. Therefore, for the technical development of the coal mine all-hydraulic core rig, the load-sensitive technology employed by the rig should be of great significance.
