How To Add Foam Liquid To A Foam Tank?

We know that the general foam tank refilling step is divided into three steps, the first is to inject water, the second is to detect leaks, and then the last step is to fill our foam liquid. And in general, the first two steps are to make the third step smoother and safer, so what are these three steps?

The first step is to inject water, which is injected into the sandwich layer of the foam jar and capsule. It must be noted that this water enters slowly, and the pressure must be controlled at 0.2MPa. This step is very important, one is to get the air in the interlayer out, so that the compression of the air can be avoided, so that the outer air bag of the capsule is pressurized and rupture, and the capsule can be suspended in water when we fill the foam liquid later, so that the inner and outer walls of the parent can be pressured. This is to avoid damage to those joints of the capsule. And the joint of the flange cover is very easy to tear. So the first step is very important.

The second step is of course leak detection, this check whether the leakage is to check whether the capsule is broken, add a certain water pressure in the sandwich layer of the capsule, of course, it is greater than the original water pressure, at this time you can see whether the capsule of our fire tank is broken.

The final step, of course, is the canned foam liquid. At this time, you must pay attention to the first two steps to do the third step. And at this time, you must pay attention to the pressure, not too high, and the water injection should be injected slowly, and must not be added to exceed some of the storage amount it is designed for. At this time, like our usual water, it has a liquid level, and it has to stop after adding it to the standard liquid level, but in the actual storage amount, this time is actually not full, that is, false. Stop for a while to see, at this time the liquid level may drop again, so that after repeated several times, it can be filled.
