《Airborne equipment environmental condition and experiment》Regulation, it is desirable that antenna can be 6.4mm in nozzle internal diameter, and vertical flow is not less than 6m
At the positions device distance 1m and water temperature be 50 DEG C solid stream of water percussion under without occur structure destroy and cosmetic variation.
1. opening water tank lid；
2. by water tank topped up with water and dustproof cover is covered on water tank；
3. the nozzle that internal diameter is 6.4mm to be mounted on to the outer end of hydraulic giant；
4. opening system power supply, it is 50 DEG C that target water temperature is arranged on temperature controller；
5. it is 6m that predetermined water spray height is arranged on water spray height controller；
It starts to work 6. blender is powered, water starts the cycle over flowing in case；

8. after pressing the Switch of spray pistol 3-1 on pressure piping, solid stream of water is projected by nozzle 3.
9. the aperture that liquid quantitative controller adjusts electric flow control valve automatically according to the pressure value that pressure gauge is fed back makes
Extra water returns to water tank.
10. after solid stream of water impact test, unclamping Switch of spray pistol, package unit power supply is closed.
Operation principle
Liquid quantitative control principle：
Power drive unit in pump group mechanism carries out the water in water tank in the process of one water suction and draining, the water of discharge
The high pressure water of low flow velocity is just formd via power drive.High pressure water is then delivered in the booster pump in pump group mechanism, warp
Pressurization is crossed to enter back into high-pressure water pipe.Since the small internal diameter of nozzle and outer end are connect with normal pressure, in high-pressure water pipe
The water of high pressure low flow velocity be changed into the water jet of low pressure high flow rate.When needing different water spray heights, water spray height control
Device calculates required nozzle exit pressure, the pressure that liquid quantitative controller feeds back pressure gauge according to desired height and jet diameters
Value is made comparisons with pressure value needed for target, and when spraying book pressure value higher than target pressure value, the aperture of electric flow control valve becomes
The extra water of ambassador is back to the pressure reduction in water tank while at nozzle until reaching required pressure value.
The operation principle of ball valve：The ball valve is one with lever and hollow metal ball device, and metal ball swims in water
The water level in current box, the lever connecting valve of the other end can be shown on position.Due to when the water level in water tank is less than heater strip
When floor level face, heater strip, which can be directly exposed in air, is possible to will appear dry combustion method phenomenon, therefore when the metal ball of ball valve
It need to give control system one feedback when minimizing water level with water level.Control system receives the electricity of cutting system after feedback signal
Source avoids the security risk caused by dry combustion method.
Temperature controlled principle：Temperature needed for experimental condition inputs desired value, temperature control in temperature control modules
The water temperature in water tank that molding programmable logic controller (PLC) in the block (PLC) is tested according to temperature sensor, which is adjusted, to be added
The output power of heated filament.Heater strip output power will be adjusted if actual water temperature and target water temperature differ greatly to maximum, if phase
Poor water temperature is smaller, reduces heater strip input power, and the input of heater strip is closed after reaching target water temperature.If test period compared with
It is long cause it is heated after case in water naturally cool to target temperature, then PLC reopens the output of heater strip according to the temperature difference.
The principle of propeller mixer be in order to prevent the water temperature around heater strip and the water temperature difference far from heater strip compared with
Greatly, it allows propeller agitator to behave in pump process, the flow in entire water tank is allowed to move up, increase heat exchange most
The water temperature reached afterwards in entire water tank is in same level.
Above-mentioned reference embodiment is illustrative to a kind of detailed description that the experimental rig of anti-solid stream of water impact carries out
Without being restrictive, several embodiments can be enumerated according to limited range, therefore total not departing from the utility model
Change and modification under body design, should belong within the scope of protection of the utility model.
