Problems solved by technology

However, for commonly used engineering materials, when the nozzle pressure is higher than 1500MPa, the nozzle will be deformed and damaged, and the liquid jet device can usually only be used once, causing a lot of waste

Abstract

The hypersonic liquid jet generator includes one outer cavity, inside which, there are free piston, regulating ring, rubber washers, diaphragms, O-rings, liquid chamber and nozzle. Outside the nozzle, there are ring step and matching flange fixed to the outer cavity; and the outer cavity is screw fixed to the support flange with O-ring in between. The present invention can produce liquid jet of 2-5 Km / s or even hight speed and can jet hypersonic liquid flow in vacuum or high pressure gas environment. The present invention also has the advantages of jetting hypersonic liquid flow in various gas environment and in arbitrary angle, so that it may be used in the research of liquid atomizing course.

Description

technical field [0001] The invention relates to a supersonic liquid jet generating device. Background technique [0002] Liquid jets include continuous jets and pulsed jets. It is technically impossible to increase the pressure of the fluid to a pressure of 1000MPa to 10GPa or higher by means of a continuous jet, so it is also impossible to produce a continuous hypersonic liquid jet. Devices for producing pulsating liquid jets have used either piston impact to squeeze the liquid, or shaped explosives. Although shaped explosives have been used to produce metal jets, they have not been widely used to produce liquid jets due to their high price and danger, and for liquids with low surface tension and easy to be atomized, shaped explosives are used to produce The liquid jet has a strong instability. Theoretically speaking, the method of squeezing the liquid with the impact of the piston can reach any high nozzle pressure, as long as the piston has a ...
