Abstract：

In　this　paper,　a　performance-testing　platform　of　hydraulic　diaphragm　metering　pump　using　R123　was　designed　and　built　under　simulative　organic　Rankine　cycle　(ORC)　conditions.　By　adjusting　stroke　and　outlet　pressure　of　the　pump,　characteristic　curves　of　hydraulic　diaphragm　metering　pump　were　obtained.　The　influences　of　key　parameters　of　hydraulic　diaphragm　metering　pump　on　the　performance　of　the　ORC　system　under　variable　operating　conditions　were　analyzed.　Results　indicated　that　for　hydraulic　diaphragm　metering　pump　the　flow　rate　and　outlet　pressure　are　independent,　Under　variable　operating　conditions,　the　input　power　and　the　actual　efficiency　of　hydraulic　diaphragm　metering　pump　increases　with　stroke,　and　the　maximum　value　can　reach　to　523.91　W　and　88.27%,　respectively.　The　heat　absorption　of　the　ORC　system　has　a　wide　range,　and　the　maximum　thermal　efficiency　of　the　ORC　system　can　reach　to　12.81%.　Hydraulic　diaphragm　metering　pump　is　more　suitable　for　the　ORC　system　under　variable　operating　conditions.　Coordinating　the　control　of　the　hydraulic　diaphragm　metering　pump　stroke　and　the　outlet　pressure　can　improve　the　thermal　efficiency　of　ORC　system　for　automobile　and　increase　the　net　output　power　of　the　ORC　system.　©　2020,　Editorial　Board　of　Acta　Energiae　Solaris　Sinica.　All　right　reserved.
