Description
Technical field
The present invention relates to the water jet source device that a kind of pressure is constant, belong to acoustic measurement field.
Background technology
Submerged jet noise is because the radiated noise that interaction produces when the water of high speed drastically blends hydrostatic, is turbulent flow
Noise, the radianting capacity of jet noise is produced for evaluation different spray nozzles, it is desirable to which during realizing jet stream, the pressure of jet source is protected
Hold constant, at present, common jet source mainly has three kinds：A kind of is to be inflated, added into the container of water storage using pressurized tank
Pressure, is connected to nozzle, so as to form submerged jet using pipeline by the water in container；It is second, straight using plunger pump combination energy storage equipment
Connect and send water to nozzle through pipeline, form submerged jet；Third, using being placed on water tank at certain altitude, by pipeline by water
The relatively low nozzle in position is connected to, using the water-head between water tank and nozzle, the pressure formed by the gravity of water, realizes water
Lower jet stream；But also have the following disadvantages in use：First, it is inflated, is pressurizeed in fact into tank using pressurized tank
Existing submerged jet, since the coefficient of bulk compressibility of air is much larger than water, after the water in tank continuously ejects, holds
The process of volume of air increase compensation water reduction is a homeostasis process in device so that the pressure at nozzle changes,
Cause the speed of jet stream unstable；Second, the submerged jet that plunger pump combination energy storage equipment is realized, used although can eliminate
The pressure fluctuation of the plunger pump of journey influences, but plunger pump is easily influenced by voltage ripple of power network at work, is caused at nozzle
Flow velocity change, and due to larger flow resistance effect caused by smaller nozzle, be often unable to stand plunger pump, fragile column
Plug pump；Third, the submerged jet realized using the water tank of eminence, when water level gradually reduces in water tank so that the pressure at nozzle
Also reducing, causing the speed of jet stream unstable.
