Analyze and Verify Energy Saving Technology of Shield Propulsion Hydraulic System

In order to solve the problem of high energy consumption of hydraulic system, two common control systems of "pump control speed regulation+valve control pressure regulation" and "valve control speed regulation+valve control pressure regulation" are the research objects. This paper introduces the working principle of the two kinds of thrust systems, the energy-saving effects of the two propulsion systems are compared and analyzed through theory and simulation. It is concluded that the energy-saving ratio of the "pump-controlled speed-regulation+valve-controlled pressure-regulation" propulsion system has reached 30%~40% compared to the valve-controlled speed regulation+valve-controlled pressure regulation propulsion system, and the efficiency of the thrust system of the "pump control speed regulation+valve control pressure regulation" is more obvious. Finally, the theory and simulation results are verified through engineering application, it provides a certain reference for the research of energy-saving technology of shield machine.
