液压泵是液压系统中的关键元件。当前我国使用的液压泵故障较多、寿命较短,这和系统的严重污染是直接有关的。为了研究和分析污染物对液压泵的磨损,对其性能、寿命的影响,以进一步改进液压泵的结构,提高泵的抗污染磨损能力,确定系统的合理过滤精度,作者设计制造并安装了液压泵污染磨损(污染敏感度)试验台。一、试验台及其液压系统试验系统为开式液压系统,如图1所示。主要包括以下三个同路。一、主回路该回路对被试泵1的耐污染磨损性能进行试验。辅助泵2从油箱8-1吸油,将油液送入被试泵。自被试泵1排出的
Hydraulic pumps are the key components in a hydraulic system. The current hydraulic pump used in China more failures, shorter life expectancy, which is directly related to the serious pollution of the system. In order to study and analyze the impact of pollutants on the hydraulic pump wear and tear on its performance, life expectancy, to further improve the structure of the hydraulic pump to improve the pump anti-pollution wear ability to determine the reasonable filtration system, the author designed to manufacture and install the hydraulic Pump contamination wear (pollution sensitivity) test bed. First, the test stand and hydraulic system test system for the open hydraulic system, shown in Figure 1. Mainly include the following three same path. First, the main circuit of the circuit on the test pump 1 wear-resistant performance test. The auxiliary pump 2 sucks oil from the fuel tank 8-1 and sends the oil to the test pump. Since the test pump 1 is discharged
