About Journal Experts Special
Chinese Hydraulics & Pneumatics, founded in 1977 with support from Beijing Research Institute of Automation for Machinery Industry, is a scientific journal that is intended to communicate information and reflect trends referring to hydraulics and pneumatics. Its publications cover both basic and applied research focusing on new technology, new design, new equipment and new material, and also introduce the industrial information on products and enterprises. Engineering technicians are the primary audience for the journal, which is also widely popular with business managers and marketing staffs as well as teachers and students in universities and colleges.Chinese Hydraulics & Pneumatics publishes in China as well as abroad.

Influence of Valve Port Differential Pressure on the Luminescence of Hydraulic Cavitation
DUAN Bo-song1, ZHANG Jian2, JIANG Ji-hai1
For hydraulic systems, cavitation occurs when hydraulic oil flows through the throttle port, even when serious this problem produce luminous phenomenon. This paper introduces the causes of luminescence and the influencing factors affecting the size of cavitation and the intensity of luminescence. And this paper aims to test the influence of the pressure difference before and after the valve opening on the cavitation luminescence by experimental verification. Finally it proves that the pressure difference is the influencing factor of luminescence, and with the increase of pressure difference, the phenomenon of cavitation luminescence is more serious. So then it has found a way to reduce the cavitation luminescence.
