Lubrication and leakage characteristic research of aviation plunger pump considering plunger deflection

Du Yuanying,
Chen Bojian,
Cao Qinxin
et al.

Abstract: Aiming at the crucial issues of serious friction, wear and large leakage in the key friction pair on the aviation plunger pump, the influence factors of pressure and shear flow are introduced to correct the Reynolds governing equation of the clearance flow, the oil film thickness equation considering the deflection of the plunger was established, and the lubrication and leakage characteristics of the plunger/cylinder pair are analyzed using finite element method, and the following conclusions are obtained: the… Show more
