The　present　article　was　to　investigate　the　mechanical　design,　efficiency,　and　performance　of　a　new　type　of　cylindrical　vane　pump.　The　configuration　is　proposed　on　the　traditional　working　principle　of　the　hydraulic　pump.　The　stator　surface　equations　are　driven　by　using　the　geometric　theory　of　applied　spatial　triangulation　function.　The　three-dimensional　model　of　the　cylindrical　vane　pump　is　established　with　the　help　of　MATLAB,　and　Pro/E.A　displacement　formula　is　derived,　which　depends　upon　the　design　structure　of　the　cylindrical　vane　pump.　The　flow　output　characteristics　of　the　pump　are　analyzed.　According　to　the　kinematic　analysis　of　the　stator-cylindrical　vane　by　Pro/Mechanism,　the　kinematic　equation　of　the　cylindrical　vane　is　established　and　the　kinematic　analysis　proves　the　effectiveness　of　structural　design　of　vane　pump.　The　CFD　software　COMSOL　is　used　to　simulate　the　force　of　the　main　parts　under　the　different　dynamic　conditions,　and　the　discharge　flow　of　the　pump　are　monitored.　The　result　shows　that　the　hermetic　space　is　formed　by　the　cylindrical　vane,　driving　plate　and　the　surface　of　the　stator,　and　the　size　of　the　hermetic　space　is　charged　by　the　rotation　of　the　cylindrical　vane.　The　cylindrical　vane　pump　satisfies　the　three　elements　design　of　positive　displacement　pump.　The　angle　at　the　arc　transition　of　stator　surfaces　is　5　degrees-10　degrees,　when　the　number　of　cylindrical　vanes　increased,　the　flow　pulsation　of　cylindrical　vanes　decreased　and　vice　versa.　There　is　a　3.6%　error　between　theoretical　and　simulation　results.　The　simulation　result　shows　that　the　internal　flow　of　the　flow　field　is　regular,　the　deformation　is　small,　and　the　stress　distribution　of　the　main　components　is　regular.
