Manufacturing slip ring brushes classification of raw materials used

 In some applications , the separation of the rotor and the contact brush set size can be solved the issue of limiting the installation ; LPS series of discrete high-current slip ring 10 to provide 2-way path to the rotor and the contact brush set , comprising a central through-hole ( 9.55mm/60mm) and non- vias for selection ; particularly suitable for a variety of small precision instruments ; can be customized according to the specific needs of various types of discrete slip ring ;

        LPK series disc dedicated to the slip ring in the vertical direction with height restrictions rotation system ; Separate Slip Rings brush fibers using advanced technology to ensure low friction, low contact resistance , friction debris , the minimum thickness of only 6mm, outer 82mm diameter solid and different sizes available vias choice.

       Manufacture three types of raw materials used brushes , one metal powder ; Second, carbon and graphite powder ; Third binder . brush slip ring with the working conditions of the motor are different, so a wide variety of brushes . Different brands of brushes , its technical performance are quite different . We therefore need to adjust the recipe and process . Formulation consists of: ! ) Use of different materials and proportion ; " ) powder of grain size ; # ) type of binder , the nature and the proportion of manufactured materials used in many brushes , they have different physical structure and properties of the different nature of these materials mixed with a certain proportion , the raw feed is obtained with a single combined effect of different properties . powder grain size , affect its bulk density between the particles overlap each other because the differences , resulting in varying degrees of porosity ( porosity ) . finer particles , the greater the surface area , to be more adhesive . different aspect ratio particles , forming the brush is anisotropic . coal tar , coal tar binder very complex composition , its production methods, technical indicators, and the amount added , are a direct impact on the final properties of the product and so far , it can not be based brush performance requirements, using theoretical calculation methods, design product formulations . generally based on theoretical and practical test method to determine the combination when the production process and quality of raw material is changed, the original may not be applicable with convenient , you should modify the process and formula , in order to meet the set quality standards and requirements for use of credit higher product , you should try to maintain the stability of formulations and processes .
