Technical field
The present invention relates to abrasive water-jet mechanical equipment design fields more particularly to a kind of dead axle away from frictional carwash
Device detects jet parameters laboratory apparatus.
Background technique
Water jet is that the high speed water a fluid stream of different shapes formed is flowed out by nozzle, and the flow velocity of jet stream depends on jet expansion
Pressure drop before and after section.Water jet is simplest a kind of form of energy conversion and application.In general, power-driven pump passes through
One suction is completed to water, is drained through journey, a certain amount of water pump is sent to pressure duct, it is made to reach nozzle with certain energy.And it sprays
The aperture of mouth requires more much smaller than pressure duct diameter, therefore reaches this certain amount of water of nozzle to mass flowing nozzle hole,
It must accelerate.In this way, accelerating the water of cohesion to be formed jet stream by nozzle bore.Abradant jet refers to abrasive material in certain outer power
Under the action of be accelerated after, the abrasive material of high-speed motion is formed by jet stream.Traditional abrasive water jet flow device is using water as Jie
Abrasive material after so that it is obtained huge energy by high-pressure generation equipment, then is directly injected into high pressure water by feeding device, is made by matter
