EXPERIMENTAL STUDY OF EFFECTS OF OPERATING CONDITIONS ON THE
FLOW CHARACTERISTICS OF WATER HYDRAULIC THROTTLE*
Abstract: Experimental investigations are made on the effects of operating conditions on the flow characteristics of throttle when tap water is used as the working media. The researched throttles include cone poppet valve, ball valve, disc valve and dumping orifice. Operating condition includes poppet lift, working media, back pressure, medium temperature, etc. Because the vapourous pressure of water is much higher than that of oil, cavitation is easier to occur in water hydraulic elements and systems, so the effects of operating conditions on the cavitation characteristics of throttle are also researched.
Key words:
