一、序言对于制造厂来说,双联轴向柱塞泵原来主要是为了用于行走的建筑机械,尤其是液压挖掘机而发展的。在这类设备上,为了能同时实现机器的不同动作(例如提升机构的动作和转盘的回转),要求有一种带有多个独立回路的大功率高压泵。由于实际上在设备上仅有一个驱动油泵的能源,大部分是用柴油机,因此, First, the preamble For the manufacturer, the double axial piston pump originally mainly used for walking construction machinery, especially hydraulic excavators and development. In this type of equipment, a high-power, high-pressure pump with multiple independent circuits is required in order to be able to simultaneously effect the different movements of the machine, such as the movement of the lifting mechanism and the rotation of the carousel. Since in fact there is only one energy source driving the pump on the equipment, mostly diesel engines,
