| Abstract: | Aimed at the frequent damages and failures of high-pressure water pump of milling machine, tests were run on working pressure and related parameters in order to figure out the causes. The results show that when the load fluctuates significantly or the flow of drive oil becomes unstable, or the oil returns with high backpressure in water pump, the working condition for water pump turns bad, which causes most of the failures. Based on information above, solution was proposed, and problems were solved. |
