In accordance with the requirements of the use of graphite bearings can be used in the following three ways to install. 1 shrinkage mounting method The method is mainly used in PV large bearing. It is well known that the graphite bearing has a lower coefficient of thermal expansion and elastic modulus, it is difficult to keep it firmly in the metal sleeve. Therefore, only the beginning of high tolerance to go in, for this, the cold state bearings can be loaded into a pre heated to a certain temperature of the metal sleeve. The preheat temperature should not be less than the maximum operating temperature. The metal sleeve is then cooled to shrink, so that a certain pressure is…
What is graphite products? What are the characteristics of graphite products? What graphite products can be made from ordinary graphite? let me tell you one by one. Graphite products are made of synthetic graphite and natural graphite according to the properties of the graphite. The characteristics of graphite products have are as following: 1).Graphite products have excellent adsorption. The open space structure of carbon has excellent adsorption, so carbon is often used as adsorption material for the adsorption of water, odor, toxic substances, etc.. 2).Graphite products have excellent thermal conductivity, fast heat transfer, uniform heating, fuel saving. 3).Graphite products have the abilities of chemical stability and corrosion resistance. Graphite has excellent chemical stability at room temperature, without any corrosion of…
The graphite electrode has the advantages of easy processing, high metal removal rate in EDM, as well as a small loss of graphite. Therefore, more and more mold factory abandon the use of copper electrode and choose graphite electrode. So, what are the advantages of graphite?1).The proportion of graphite is copper 1/5, the weight of the same volume of graphite is 5 times lighter than that of copper. the large electrodes made from copper are too heavy, in the long running, it is very unfavorable to the accuracy of the machine tool spindle on the EDM. But graphite is opposite and in safe handling!2).The graphite can have a very high processing speed, the general speed of the processing of graphite…
