恒压变量机构控制的轴向柱塞泵是一种恒压油源,它能根据工程机械液压系统中的工作油缸变速的需要而能自动变量调节并能恒定系统的压力。该泵在工程机械液压系统中可作为节能油源使用。为了使工程机械液压系统在工作的动态过渡过程中有良好的过渡过程品质,以减少能量消耗,在选用该泵时,了解其特性是十分必要的。为此,本文对63PCY14-1B型 Constant pressure variable displacement control of the axial piston pump body is a constant pressure oil source, it can work in accordance with the construction machinery hydraulic system hydraulic cylinder speed requirements can be automatically variable adjustment and constant system pressure. The pump in the construction machinery hydraulic system can be used as an energy source of oil. In order to make the hydraulic system of construction machinery have a good transitional process quality during the dynamic transition of work, in order to reduce the energy consumption, it is very necessary to know its characteristics when choosing the pump. To this end, this article on the 63PCY14-1B type
