The brush, which plays a vital role in the sensor, is still mainly relying on foreign imports until December 2012, and domestic manufacturers with so-called "precious metals" to promise N million times of life, so how is this N million times of life?
First: what is the pressure of the brush?
Second: different width, different length, the same Angle of pressure is not the same, how to calculate?
Third: different materials, different HV values, tensile strength pressure is not the same.
Fourth: the mechanical structure of the brush how to ensure the wear of the brush resistance sheet?
These all play a vital role in the life of the product.
In view of the above problems, after three years of analysis and verification of the performance of each part of the brush, as well as the calculation of pressure and the method of combining the brush with the resistor, Komin Company has successfully broken through this technology and is now in the leading position in China.
While successfully developing the welding technology of filamentous brush, in November 2012, Komin successfully processed the contact of the head of the sheet brush into an arc, which solved the phenomenon of abrasion of the resistance sheet by the brush to a greater extent.
