    摘要:

    提出了一種傅里葉非圓齒輪驅(qū)動的四葉片差速泵,，并在葉片上安裝與轉(zhuǎn)動方向相同的單向閥。建立了傅里葉非圓齒輪傳動模型和差速泵瞬時流量模型,，采用Matlab編寫了分析設(shè)計軟件,。利用該軟件分析了相同泵結(jié)構(gòu)參數(shù)下的3組典型節(jié)曲線參數(shù)對節(jié)曲線形狀、差速泵瞬時流量,、排量,、單雙泵和單向閥對脈動率的影響，并與偏心圓—非圓齒輪驅(qū)動的四葉片差速泵比較,，得到雙泵并聯(lián)的傅里葉非圓齒輪驅(qū)動的差速泵相比偏心圓—非圓齒輪驅(qū)動的差速泵在排量相當(dāng)?shù)那闆r下能使脈動率降低10.3%,，在葉片上安裝與轉(zhuǎn)動方向相同的單向閥有效地解決了困液問題。

    Abstract:

    A differential velocity vane pump driven by Fourier noncircular gear was designed and the blades of pump were equipped the check valves in the same direction of rotation. Through the establishment of non-circular gears Fourier model and instantaneous flow models and design of the simulation software, we analyzed the influence of the three typical parameters on the shape of the section curve, the flow rate, displacement, pump structure and single or double pump, check valve on the blades to the pulsation rate. Dual pumps in parallel driven by the Fourier non-circular gear were compared with that driven by the eccentric gear to reduce pulsation rate 10.3%. And the installation of the check valve can solve the problem that the liquid trapped in closed chamber.
