RELIABILITY OPTIMIZATION DESIGN OF INTELLIGENT MECHANICAL STRUCTURE FOR WASTE HEAT RECOVERY

ABSTRACT
In order to solve the problems of high energy consumption and serious waste of heat energy in the cooling of traditional oil cooler in hydraulic system, the author proposed the reliability optimization design of intelligent mechanical structure for waste heat recovery. The author has built a waste heat recovery test platform for hydraulic system, the influence of electrical load, oil flow rate and working medium flow rate on system operation and energy characteristics is studied. The experimental results show that: under the same working condition, compared with the oil cooler of the same specification, the maximum thermal efficiency of the proposed organic Rankine cycle waste heat recovery system is increased to 2.56%. The expander pressure ratio and system thermal efficiency increase with the increase of electric load and oil flow rate. With the increase of the flow rate of the working medium, the superheat of the working medium at the inlet of the expander decreases significantly, while the heat exchange of the evaporator and the output power of the expander increase. Under the test condition, the maximum heat exchange of evaporator is 4.18 kW, and the maximum output power of expander is 356 W. The energy saving effect of waste heat recovery system of hydraulic system is obtained, and the influence law of operation parameters on system performance is obtained.
