Graphite sealing ring graphite carbon ring seal sleeve is a kind of parts widely used in various mechanical seal occasions, because of its excellent corrosion resistance, high temperature resistance and lubrication characteristics, it is widely used in chemical, petroleum, pharmaceutical and food industries. The processing of graphite sealing ring graphite carbon ring seal sleeve needs to go through multiple processes, and the processing technology of graphite sealing ring graphite carbon ring seal sleeve will be introduced in detail below.
1. Preparation of raw materials.
The raw materials of graphite sealing ring graphite carbon ring sealing sleeve are generally natural graphite or artificial graphite, and graphite material has high corrosion resistance and high temperature resistance, as well as good mechanical properties and electrical conductivity. Before processing, the graphite material needs to be inspected and treated to ensure that its quality meets the requirements.
2. Blank preparation.
The blank preparation of graphite seal ring graphite carbon ring seal bushing can be done by different methods, such as mold pressing, extrusion, and injection molding. Among them, mold pressing is the most commonly used method, that is, graphite powder is mixed with an appropriate amount of binder and then pressed in the mold. During the preparation process, the size and density of the blank need to be controlled to ensure that it meets the requirements.
3. Rough machining.
Roughing is mainly to process the shape of the graphite sealing ring graphite carbon ring seal bushing, such as turning, milling and grinding. During machining, it is necessary to control the amount of stock removal and cutting speed to avoid damage or excessive wear to the graphite seal. At the same time, the surface of the graphite sealing ring also needs to be treated to improve its hardness and wear resistance.
Fourth, finishing.
Finishing is mainly to process the size and accuracy of graphite sealing rings, graphite carbon ring sealing bushings, such as grinding and polishing. In the process of processing, it is necessary to control the processing parameters and the selection of tools to ensure that the size and shape of the graphite sealing ring meet the requirements. At the same time, the surface of the graphite seal also needs to be treated to improve its finish and corrosion resistance.
5. Testing and packaging.
After the processing is completed, it is necessary to inspect the graphite sealing ring and graphite carbon ring sealing sleeve, such as size inspection, appearance inspection and performance testing. Only graphite seals that pass the test can be packaged and put into storage. In the packaging process, it is necessary to select appropriate packaging materials and methods to ensure that the graphite sealing ring and graphite carbon ring sealing sleeve are not damaged during transportation and storage.
