主要论述了新型结构的CBZ型高压齿轮泵由于采用了径向浮动补偿装置,使外啮合齿轮泵压力级提高到31.5M Pa,但由于升压产生高频噪声,引起压力波动与振动而造成气蚀现象。文中通过分析、计算,试图阐述如何消除气蚀现象。 Mainly discusses the new structure of the CBZ-type high-pressure gear pump due to the use of radial drift compensation device, the external gear pump pressure level increased to 31.5M Pa, but due to boost high-frequency noise, causing pressure fluctuations and vibration caused by gas Erosion phenomenon. Through analysis and calculation, this article attempts to explain how to eliminate cavitation.
