Regarding the issue of restoring the floating disk of an internal floating disk tank to its suspended position
Thread Content
In a floating disk tank at a certain facility, due to improper operation by the staff, the scale got stuck at the 6-meter mark； The employees failed to report the situation in a timely manner. When the loading crew filled the tank, they did not check it; the oil in the tank was filled up to a level of 2 meters, which caused the floating disk to hang at a height of 6 meters. I would like to ask my colleagues: is it possible to introduce oil flow so that the inner floating disk can return to its original position naturally? Thank you for your advice.
It’s possible in theory. A breather valve is usually present on the floating disk to allow air intake and exhaust. Feed oil slowly to gradually discharge the gas phase beneath the floating disk. When the oil level comes into contact with the float disc, it can lift the float disc. That’s how you fill an empty tank with oil.
Our unit has also encountered problems with the scale sticks on the tanks in the past, all caused by the operators using too much force； The same method is used, namely introducing oil to allow the floating disc to rise naturally. But this time, the position of the card was too far away from the oil level – 4 meters apart. It was the first time I encountered such a severe situation. So, the leader is a bit worried about whether this method can be used for restoration. I’m hoping that when oil is arranged to be poured into the tank, it will be possible to reset it.
It’s possible, but it needs to be dealt with as soon as possible; if too much time passes, the floating pad will deform significantly, which will cause problems. To control the oil inlet speed, nitrogen is used for protection.
Thank you for your feedback. Yesterday, we finally got the chance to refuel. Fortunately, the scale is still functional, and the inner float can rise properly. By comparing the liquid level shown on the control panel with that at the actual site, the readings match, indicating that there has been no deformation. Additional note: This tank contains 5# white oil. With a 4-meter clearance above the ground, there was concern that the rope would not be strong enough to hold up and that the inner floating disc might fall and get damaged.
Since this is the second time the problem has occurred, the scale issue should be taken into consideration; this caliper problem can definitely be solved. Maybe next time it will fall off and cause an explosion
http://www.lygmuchen.com/ Lianyungang Muchen Fluid Equipment Manufacturing Co., Ltd. specializes in the custom fabrication of aluminum alloy internal floating disks, stainless steel S30408/316 float-type internal floating disks, and stainless steel S30408/316 fully submerged internal floating disks. Seals include large-compensation high-efficiency seals/bi-metallic seals, bladder seals, tongue seals, as well as secondary seals. Attach a flexible hose. Technical explanations of the drawings are provided, along with 3D drawings; shipping costs are included for the full liquid-contact internal floating disk package. Lianyungang Muchen internal floating roof is a floating cover that floats on the surface of the oil tank and rises and falls along with the level of the oil. Using such an internal floating roof to cover the liquid surface is currently recognized as the most economical and simple method for reducing oil evaporation losses. Under specific conditions, data from relevant manufacturers show that within 3 to 6 months of installing an internal floating roof, the economic savings resulting from reduced oil and gas vaporization equal the cost of installing such a roof; in other words, the cost of the internal floating roof can be recovered within half a year. It is suitable for docking tanks and overlapping tanks of various sizes; it does not contaminate oils or chemicals, reduces vapor losses of the medium, and prevents air pollution, making it an ideal internal floating roof (disk). It features low cost, short construction time, corrosion resistance, no space occupation, and a long service life. Contact number: 1866, 125, 1137
