Design And Research Of Hydraulic System Of Energy Saving Type Stereo Parking Lot

This paper mainly is the study of the hydraulic system for energy saving type stereoscopic parking space.Analysis of the hydraulic system of stereo parking,established energy-saving hydraulic system with two kinds of research to improve the way,one way is variable frequency speed control using variable frequency motor and pump.It makes the system pump provides flow according to the rotating mechanism,a walking mechanism and a lifting mechanism in under the condition of different demand to provide flow,to achieve on-demand supply.The overflow loss and throttling loss this can effectively avoid the resulting from the original quantitative pump supply constant flow.Because the pump with flow rate decreases,the energy consumption of themotor also decreased.Another way is to use the accumulator as the energy recovery device for recovering the lifting cylinder down potential energy released.In the lifting cylinder to rise again,the device provides pressure oil for the oil pump storage power,because the difference reduced import and export pressure pump,the motor energy consumption is also reduced,achieve the purpose of saving energy.By energy calculation comparison before and after the motor energy consumption and energy-saving hydraulic system's annual energy,the calculation results show that the effect of energy saving,energy-saving system is good,can reduce the circuit energy consumption to a certain extent.Use hydraulic system simulation software AMESim to establish the rotary lifting loop circuit and the walking circuits simulation model,Through simulation of rotary loop and the walking circuits to use energy-saving inverter,And the energy storage circuit is simulated,by using simulation software results and the calculated results match the design of the hydraulic system,verified the rationality and feasibility of the accumulator of energy saving.Research and development of energy saving type stereo parking hand solves the city"parking difficult" problems,on the other hand,in the face of the current situation of the energy shortage,can effectively save energy,green environmental protection.Therefore,the successful development of the equipment,can be long-term security and stability operation,market prospect is very broad,has the extremely vital significance on the market.
