    摘要:

    通過外環(huán)流轉(zhuǎn)子泵運(yùn)轉(zhuǎn)時(shí)泵的轉(zhuǎn)子與軸的受力分析,，建立力學(xué)模型,，導(dǎo)出了該泵轉(zhuǎn)子與泵體間的間隙計(jì)算式,；依據(jù)N-S微分方程,，推導(dǎo)出轉(zhuǎn)子泵間隙的漏損公式,。試驗(yàn)驗(yàn)證了間隙和漏損計(jì)算公式的實(shí)用性,，為提高該泵的設(shè)計(jì)水平及性能提供了參考依據(jù),。

    Abstract:

    With respect to stress condition of external circulation rotor pump during operation, through stress analysis of pump rotor and shaft, a mechanical model was built up and the calculation formula was derived for the gap between the pump rotor and pump body; according to Navier-Stokes differential equation, the leakage loss equation for the gap of rotor pump was deduced, and through comparative tests, the practicability of the calculation formulae for the gap and leakage loss were verified, which provided a theoretical guidance for improvement of design level and performance of the pump.
