Abstract:
(EN) Provided are a positive-displacement pump (1) and an oil production device using the positive-displacement pump (1). The positive-displacement pump (1) comprises a housing (101), wherein the housing (101) is provided with a liquid discharging end and a cylindrical pump chamber, at least one liquid inlet (105) is arranged in a side wall of the housing (101), and a liquid discharging channel (106) is formed inside the side wall of the housing (101); a rotor body (102) capable of rotating around an axis thereof is coaxially embedded in the housing (101), at least one through hole, that is used for guiding liquid at the liquid inlet (105) side into the liquid discharging channel (106), is formed in the rotor body (102), a plunger (103) is slidably arranged in each through hole, various plungers (103) are arranged in sequence in an axial direction of the rotor body (102), and all the axes of the various plungers (103) are perpendicular to the axis of the rotor body (102); and a transmission crankshaft (104), that is used for driving the various plungers (103) to reciprocally slide and move in the corresponding through hole, is coaxially arranged in the rotor body (102).
(FR) L'invention concerne une pompe volumétrique (1) et un dispositif de production d'huile utilisant la pompe volumétrique (1). La pompe volumétrique (1) comprend un corps (101), le corps (101) étant pourvu d'une extrémité de refoulement de liquide et d'une chambre de pompe cylindrique, au moins une entrée de liquide (105) étant disposée dans une paroi latérale du corps (101), et un canal de refoulement de liquide (106) étant formé à l'intérieur de la paroi latérale du corps (101) ; un corps de rotor (102) pouvant tourner autour de son axe est intégré de manière coaxiale dans le corps (101), au moins un trou traversant, qui est utilisé pour guider un liquide au niveau de l'entrée de liquide (105) dans le canal de refoulement de liquide (106), est formé dans le corps de rotor (102), un plongeur (103) est agencé coulissant dans chaque trou traversant, divers plongeurs (103) sont agencés en séquence dans une direction axiale du corps de rotor (102), et tous les axes des différents plongeurs (103) sont perpendiculaires à l'axe du corps de rotor (102) ; et un vilebrequin de transmission (104), qui est utilisé pour entraîner les divers plongeurs (103) de sorte à coulisser et à se déplacer en va-et-vient dans le trou traversant correspondant, est disposé de manière coaxiale dans le corps de rotor (102).
(ZH) 一种容积式泵(1)及采用该容积式泵(1)的采油装置,该容积式泵(1)包括壳体(101),壳体(101)具有排液端及圆柱形泵腔,壳体(101)侧壁上开设有至少一个进液口(105),壳体(101)侧壁内形成有排液通道(106);壳体(101)内同轴嵌装有可绕自身轴线旋转的转子体(102),转子体(102)内形成有至少一个用于将进液口(105)侧的液体导引至排液通道(106)内的贯通孔,每一贯通孔内滑设有一个柱塞(103),各柱塞(103)沿转子体(102)的轴向依次设置,各柱塞(103)轴线均与转子体(102)的轴线垂直;转子体(102)内同轴设有用于带动各柱塞(103)在对应的贯通孔内往复滑移的传动曲轴(104)。
