Title (EN) ELASTIC PISTON, PUMPING SYSTEM AND ENGINEERING MACHINE
(FR) PISTON ÉLASTIQUE, SYSTÈME DE POMPAGE ET MACHINE D'INGÉNIERIE
(ZH) 弹性活塞、泵送系统及工程机械
Abstract:
(EN) An elastic piston (40) comprises a piston body (1) and an elastic seal body (2). The piston body (1) and/or the elastic seal body (2) are provided with a pressurization cavity (3). The piston body (1) is provided with a pressurization channel (4) connected with the pressurization cavity (3). Compared with the prior art, the elastic piston (40) has a longer service life and better use effects. Besides, a pumping system and engineering machine with the elastic piston (40) are proposed.
(FR) La présente invention se rapporte à un piston élastique (40) qui comprend un corps de piston (1) et un corps de joint élastique (2). Le corps de piston (1) et/ou le corps de joint élastique (2) comportent une cavité de mise sous pression (3). Le corps de piston (1) comporte un canal de mise sous pression (4) raccordé à la cavité de mise sous pression (3). Par comparaison avec l'état de la technique, le piston élastique (40) présente une durée de vie plus longue et de meilleurs effets d'utilisation. En outre, la présente invention se rapporte à un système de pompage et à une machine d'ingénierie comprenant le piston élastique (40).
(ZH) 一种弹性活塞(40)包括活塞本体(1)和弹性密封体(2)。活塞本体(1)和/或弹性密封体(2)上设有充压腔室(3)。活塞本体(1)上设置有与充压腔室(3)连接的充压通道(4)。与现有技术相比,该弹性活塞(40)的使用寿命更长,且使用效果更佳。另外,提出了一种具有该弹性活塞(40)的泵送系统及工程机械。
