Title (EN) PUMP BODY ASSEMBLY, FLUID MACHINERY, AND HEAT EXCHANGE APPARATUS
(FR) ENSEMBLE CORPS DE POMPE, MACHINERIE À FLUIDE ET APPAREIL D'ÉCHANGE DE CHALEUR
(ZH) 泵体组件、流体机械及换热设备
Abstract:
(EN) A pump body assembly comprises: a rotary shaft (10) having a rotor portion (11), wherein the rotor portion (11) is provided with multiple sliding vane slots (111); a cylinder (20), wherein the rotary shaft (10) passes therethrough, and the cylinder (20) has an inner cavity (21); multiple sliding vanes (30) capable of sliding within the sliding vane slots (111), wherein a head portion of the sliding vane (30) is in contact with a cavity wall of the inner cavity (21); multiple sliding vane springs (40), are provided in the sliding vane slots (111) and located at a tail portion of the sliding vanes (30); and multiple guide structures (50) provided in the sliding vane slots (111) and extending outwards in a moving direction of the sliding vanes (30), wherein the sliding vane spring (40) sleeves onto the guide structure (50). The invention further discloses fluid machinery having the pump body assembly described above and a heat exchange apparatus. The above structure prevents the sliding vane (30) of the pump body assembly from separating from the cylinder (20), thereby prolonging service life of the sliding vane (30), the cylinder (20), and the rotary shaft (10).
(FR) L'invention concerne un ensemble corps de pompe comprenant : un arbre rotatif (10) pourvu d'une partie rotor (11), la partie rotor (11) comportant des fentes de palettes coulissantes multiples (111) ; un cylindre (20) traversé par l'arbre rotatif (10) et comprenant une cavité interne (21) ; des palettes coulissantes multiples (30) aptes à coulisser à l'intérieur des fentes de palettes coulissantes (111), une partie tête de la palette coulissante (30) étant en contact avec une paroi de la cavité interne (21) ; des ressorts de palettes coulissantes multiples (40) sont disposés dans les fentes de palettes coulissantes (111) et situés au niveau d'une partie queue des palettes coulissantes (30) ; et des structures de guidage multiples (50) disposées dans les fentes de palettes coulissantes (111) et s'étendant vers l'extérieur dans une direction de déplacement des palettes coulissantes (30), le ressort de palette coulissante (40) étant manchonné sur la structure de guidage (50). La présente invention concerne également une machinerie à fluide comprenant ledit ensemble corps de pompe et un appareil d'échange de chaleur. La structure selon l'invention empêche la palette coulissante (30) de l'ensemble corps de pompe de se séparer du cylindre (20), ce qui prolonge la durée de vie de la palette coulissante (30), du cylindre (20) et de l'arbre rotatif (10).
(ZH) 一种泵体组件,包括:转轴(10),具有转子部(11),且转子部(11)上设置有多个滑片槽(111);气缸(20),转轴(10)穿设在气缸(20)内,且气缸(20)具有内腔(21);多个滑片(30),多个滑片(30)可滑动地设置在各滑片槽(111)内,滑片(30)的头部与内腔(21)的腔壁相接触;多个滑片弹簧(40),设置在各滑片槽(111)内,且各滑片弹簧(40)位于各滑片(30)的尾部;多个导向结构(50),设置在各滑片槽(111)内,且导向结构(50)沿滑片(30)的运动方向伸出,滑片弹簧(40)套设在导向结构(50)上。还提供了具有上述泵体组件的流体机械和换热设备。采用上述结构,能够防止泵体组件的滑片(30)与气缸(20)发生脱离,进而延长滑片(30)、气缸(20)及转轴(10)的使用寿命。
