The structure of the float!
Thread Content
What is the structure of the float of the on-site magnetic flap level gauge? ? Is there a vacuum or air in the float? ?
The float is a cylinder with two end faces as semicircular spheres. Since it has to withstand a certain amount of pressure, the main body of the cylinder has reinforcing ribs (reinforcing grooves). The magnet is fixed in the hemisphere below. The volume of the float is determined according to the density of the medium. The interior should be air.
Floats can be roughly divided into two types: One has a smooth outer surface and is generally used at low pressure. The other is one with equidistant reinforcements on the outer surface. There is a partition at the bottom of the interior, with three magnets stuck on it at 120 degrees to each other. There is no vacuum inside. The common fault is: The adhesive failed, the three magnets stuck together, and the liquid level gauge became inaccurate. ； There are problems with the welding quality of the float. There are blisters, liquid has entered, and it cannot float.
