introduction：A unidirectional intermittent motion mechanism composed of a groove wheel and a cylindrical pin，Also known as the Marta Agency。It is often used to convert the continuous rotation of the driver into a one-way periodic rotation of the follower with a stop。The groove wheel mechanism has two forms of external engagement and internal engagement。The groove wheel and the rotor of the external engaging groove wheel mechanism turn opposite,The inner meshing is the same。Single arm outer engaging groove wheel mechanism(See picture[Single arm outer engaging groove wheel mechanism])By swivel arm with cylindrical pin、possess4A groove wheel and a frame are composed of a radial groove。When the cylindrical pin on the continuously rotating boom enters the radial groove,Toggle the groove wheel over2Angle;When the cylindrical pin is turned out of the radial groove,The groove wheel stops rotating。

introduction：Schematic diagram of the principle of direct-linked centrifugal extractor Equipment overview After the multiphase mixture with density difference enters the utility model，The mixed mass transfer process and the separation process are completed in the same machine。The direct-connected motor drives the drum to rotate at high speed through the coupling，Generate the required strong centrifugal force field，The motor speed is changed by frequency converter，You can change the size of the centrifugal force field，To adapt to different systems。In this centrifugal force field，The polyphase mixture is different because of its density，The centrifugal force is also different，Solid and stratified phenomenon，So as to achieve the purpose of extraction or separation。 Working principle： Machine mixing

introduction： The passivation treatment of stainless steel is to plate a layer of chromium oxide film on the surface of the steel plate and the weld，Thus improve the corrosion resistance of stainless steel。 Passivation is also an effective way to remove pollution。Such as，Iron particles deposited on metal surfaces and welds can be removed in this way(These iron particles are often due to cutting、molding、Formed by the action of instrument friction or metal brush)。 Pickling before passivation removes all contaminants，And can selectively remove small corrosion resistance areas on the metal surface。 For effective pickling and passivation，Dull under pickling
