The design about an energy saving and environmental protection type large gantry guideway grinder IPMP frequency servo hydraulic system and the energy consumption calculation were introduced.The “quantitative pump and frequency servo motor”was used to replace traditional “quantitative pump and proportional valve”system,through the inverter to control the pump speed, through pressure sensor and rotary encoder to feedback the pressure and flow signal,closed-loop control was realized,pressure and flow can be output by required,no extra power loss.4 groups of 22 kW IPMP pumping station design can meet requirements of overload, wide speed range,low power of the large gantry guideway grinder.
