Oxygen supply pump 20, three-in-one Shui nationality pump 19 itself can adjust air inflow, in order to increase sight, science popularization, with calmly
When device set respectively oxygen supply pump 20, the 19 interim air inlet of three-in-one Shui nationality pump, as a result air inflow be uneven, to ensure fish jar
Not spilling water, total air inlet ability of setting is less than the exhaust capacity of negative pressure generator 16, but does not represent the air inflow of a certain period
Always it is less than rate of air sucked in required.When normal operation, what negative pressure generator 16 was extracted out has gas and water or mixing 3 kinds of situations of aqueous vapor, if
Air inlet ability is less than exhaust capacity but necessarily has air inlet, and what exhaust tube 17 was extracted out is mixing aqueous vapor, if for a long time without air inlet, is taken out
What tracheae 17 was extracted out is water, because the inside of draft hood 18.3 fluctuation very little, high water level can slightly above 18.2 times outlets of pumping core.
Said process will consider the influence of upper hose 8, and water pump is out of service, and upper hose 8 is because removing water level in check-valves pipe
Decline, pressure reaches balance with top negative pressure, and the water inlet level of subsistence of water supply connector 9 is higher than air exhaust nozzle device 18 and is evacuated core
The height of 18.2 times outlets, top water will not be returned into upper hose 8, top water level is slightly increased.
When having a power failure or water pump damages, oxygen supply pump 20, three-in-one Shui nationality pump 19 all stop, at the top of fish jar actual water level with
The internal state of exhaust tube 17 substantially divides 3 kinds：(1) water level exports for 18.2 times less than pumping core, is gas in exhaust tube 17；(2) water level
Substantially maintain an equal level with the 18.2 times outlets of pumping core, be gas-vapor mix gas in exhaust tube 7；(3) water level is slightly above evacuated under core 18.2
Mouthful, it is water in exhaust tube 7.
Above (1), the water of bottom cylinder 2 flows through the lifting height of exhaust tube 17 equal to negative pressure part height of water level in cylinder body 1, and the two reaches
To balance, the top high water level of cylinder body 1, the change of the low water level of gathering hole 3 are little, and such case auxiliary gas-complementing devices 22 do not work.
More than (3), top high water level is slightly above evacuated core 18.2 time and exports, and is water in exhaust tube 7, hydraulic pressure in exhaust tube 7
More than the hydraulic pressure of negative pressure part in cylinder body 1, as a result current are descending in exhaust tube 7, cause under gathering hole 3, the water level of side opening 4 start
Drop.
Auxiliary gas-complementing devices 22 are not installed, the water level decreasing of side opening 4 is to being less than the hanging lower edge of side plate 2, this process meeting
Last very long, has large quantity of air to be poured in through gathering hole 3 or side opening 4 inside fish jar afterwards, and when top, water level is descend below
It is evacuated the outlet of core 18.2 time, air enters exhaust tube 7 and causes inside water pressure and the top negative-pressure balancing of cylinder body 1, while gathering hole 3,
The water level of side opening 4 rises above the hanging lower edge of side plate 2, and water body is gradually stablized.The malleation water level of gathering hole 3, top negative pressure water level
Change is very big, and the scene that large quantity of air pours in makes us being difficult to receive, and the water surface of fluctuation takes long enough just calm down, special
It is not that the water level of bottom cylinder 2 rises much, there is spilling water risk.
Auxiliary gas-complementing devices 22 are arranged on the hanging lower edge of side plate 6, and the height in its short tube portion 22.1 is slightly below overflow plate
Highly, with material making is not infiltrated, there is the features such as caliber is thin, necking is small, in addition the surface tension effects of water, it is several inside U-tube
It is air rather than water, U-tube is negative pressure on the outside of the long exit of pipe portion 22.2, when gathering hole 3, the water level decreasing of side opening 4 arrive
When exposing the short tube portion 22.1 of U-tube, air is connected in U-tube, short tube portion 22.1 of the air through U-tube enters in negative pressure cylinder body
Portion, fish jar top water potential drop is low, and pressure and the top negative-pressure balancing of cylinder body 1, air exhaust nozzle device 18 are taken out after water level decreasing in exhaust tube 7
18.2 times outlets of gaseous core and hot separation, while gathering hole 3, the external water level of side opening 4 rise, and flood the short tube portion of U-tube
22.1, the no longer air inlet of short tube portion 22.1, fish jar water body is in stable state.
The height in the short tube portion 22.1 of auxiliary gas-complementing devices 22 is more much higher than the lower edge of hanging side plate 6, avoids through gathering hole 3
Placement artificial hillock, water level fluctuation air when operating of fishing with a net pour in inside fish jar and cause big impact.
Between the situation of the above (2) in (1) and (3) between the two, no longer discuss.
The current control gas circulatory system is detected, when setting feed pump 7 reaches rated current 90% and the above, just allows to supply oxygen
Pump 20, three-in-one Shui nationality pump 19 electric operation, otherwise realize that locking can not air inlet, it is ensured that fish jar not spilling water.
The horizontal segment of the outlet pipe 14 is higher than the low water line of fish jar side opening 4, when otherwise secondary water pump 13 stops, bottom
Sewage still passes through outlet pipe 14 and flows into sewage drip cylinder, and aperture is opened in the appropriate location of outlet pipe 14, when secondary water pump 13 stops,
Air is sucked from aperture under sewage Action of Gravity Field in water pipe, a sewage part returns to cylinder base in pipe, is partly into drip
Cylinder, the effect of aperture are to stop immediately, reduce the influence to fish jar water level, water level is more steady.
The utility model can also control negative pressure fish jar by detecting pressure, and 4 logical, increasings are connect on feed pump outlet pipe
If electro connecting pressure gauge, electro connecting pressure gauge can set the size of high-low pressure operating pressure so that water pump reaches rated pressure
When more than 90%, secondary water pump, oxygen supply pump, three-in-one Shui nationality pump can obtain electric operation；So that pressure is reduced to rated pressure
When less than 80%, secondary water pump, oxygen supply pump, three-in-one Shui nationality pump do not allow to run.
