2ZB725双联轴向柱塞泵一、技术规范及结构特点: 2ZB725油泵是我厂自行设计的0.6米~3液压挖掘机的主要液压元件之一,它由两台725轴向柱塞式油泵组成,装在一个公共的壳体内,并且共用一个恒功率调节装置。两台油泵由装在公共壳体前部的分动齿轮同时驱动。由于公共壳体与油箱连通,所以两台油泵直接从壳体内吸油,而分别经过壳体上部的两个出油口,将高压油送至操纵阀。油泵的主要技术规范如下:
2ZB725 double axial piston pump First, the technical specifications and structural features: 2ZB725 pump is designed by our factory 0.6 m ~ 3 hydraulic excavator one of the major hydraulic components, which consists of two sets of 725 axial piston pump , Housed in a common housing, and share a constant power regulator. The two pumps are driven by the transfer gear mounted on the front of the common housing. Due to the communication between the common housing and the fuel tank, the two oil pumps absorb oil directly from the housing, and respectively pass the two oil outlets at the upper part of the housing to send the high-pressure oil to the control valve. The main technical specifications of the pump are as follows:
