Position fluctuation, causes the random rolling of plastic beads, thus is difficult isolation air, plus gap originally without filter bulb net, water level
Gap is risen to, a large amount of floating balls escape with current and flow into trench.Therefore the technique and unsuccessful and ineffective, after by incident
Eliminate.
Rubber pneumatic bag floating roof：It is also very stringent to water tank shape need due to capsule long-time service aging cracking, plus air bag
Interior the blowing pressure reduces, and air bag, which fluctuates, to be easily obstructed, in addition, water tank volume is huge, large-scale air bag processing technology is more complicated, to the greatest extent
The domestic a small number of import units of pipe use, but domestic equipment is not heard user.
Fill ammonia sealing：This method maintains the pressure on water tank level using pressure filling ammonia in water tank gas-liquid two-phase reasonable distribution
Power is balanced with atmospheric pressure, and one side demineralized water is alkalized, and on the other hand prevents air pollution.The technological requirement supplies ammonia regulating valve
Can accurately it automatically control, therefore the method also is difficult to promote.The country has a small number of engineerings to use the sealing means similar to above-mentioned technique, but
Because fill ammonia can not suitable control and meet with eliminate.
