Magnetic Bar Used In Filtering Machine

☑ The magnetic bar consists of an internal magnetic core and an external cladding, which includes a cylindrical magnet block and a magnetic conductive iron sheet. A good magnetic bar should achieve a uniform spatial distribution of magnetic induction lines, the maximum magnetic induction point distribution as much as possible to fill the entire bar, because it is generally placed in the moving product transmission line, the surface of the bar should be smooth resistance, does not contain environmentally harmful substances, to avoid contaminants material and the environment.

☑ The working environment of the magnetic bar determines that it needs to have certain corrosion resistance and high temperature resistance, and some occasions need strong magnetic induction. Different thicknesses of magnetic plates can be used to obtain different magnetic induction strengths. The choice of different magnets can determine the magnetic induction strength and temperature resistance of the equipment. Generally, NdFeB magnets of N40 or above are required to achieve a surface magnetic induction of 12,000 gauss or more on a conventional 1" diameter SmCo magnet. When temperatures exceed 150 degrees Celsius, high temperature resistant devices generally use SmCo magnets. However, samarium and cobalt are not suitable for large diameter magnetic rods.

☑ The surface magnetic induction of a magnet bar is directly proportional to the size of the smallest particles that can be attracted. Other fields can use a little lower.

☑ Magnetic rod in the use of fluid contact with the process of internal magnetic energy will be part of the irreversible loss, loss of more than 30% of the initial strength or the surface package of iron, stainless steel pipe wear rupture, when the need to replace the magnetic rod, and can not let the leakage of the magnetic rod continue to work, magnets are generally more brittle, the surface is also coated with some oil, the environment is more polluted.
