随着现代技术的发展，液压传动在越来越多的场合取代了机械传动，然而液压传动在向高压、高速、大功率的方向发展的同时噪声问题也显得越来越突出。为了在提高工作效率的同时降低液压系统的噪声，改善工作条件，国内外厂商研制了许多新颖的低噪声液压泵。内啮合齿轮泵虽然...
With the development of modern technology, the hydraulic transmission has replaced the mechanical transmission in more and more occasions. However, the hydraulic transmission becomes more and more prominent while it is developing towards high pressure, high speed and high power. In order to improve work efficiency while reducing the noise of the hydraulic system and improve working conditions, domestic and foreign manufacturers have developed many new low-noise hydraulic pump. Internal gear pump although ...
