Maintenance of horizontal sander 1. When the dispersing disc has been worn or partially worn and needs to be replaced with new components, first move the cylinder, then gradually remove the hexagon socket screw and the dispersing disc and bushing, pay attention to the dispersing disc during assembly. Install in the original position (due to the size of the dispersing disc), in order to maximize efficiency and extend service life.
2. When the seal is replaced, the cylinder should be released first, the dispersing disc assembly and the sieve ring device should be removed, and then the shaft should be cleaned with solvent. After all the parts are removed, it must be carefully cleaned, especially the moving ring. And static ring, to ensure that it is spotless. After cleaning, reassemble in order.
3. When the equipment is running, the circulation of the synovial fluid can be observed through the oil cup window, and whether the oil pump is supplied with oil to lubricate the mechanical seal. If the oil cup window has no oil, it should be stopped in time, otherwise the mechanical seal will be damaged, resulting in the equipment not working properly, and corresponding measures should be taken for overhaul.
4. The whole machine should be thoroughly cleaned and repaired once a year or so.
5. The pressure gauge exceeds the normal pressure, which proves that the machine is faulty. The accumulated material in the machine blocks the sieve ring. It should stop working and remove the cylinder to clean the sieve ring.
Principle and maintenance of horizontal sander
Sand mill, also known as bead mill. A type of grinding and dispersing device for solid-liquid phase dispersion of powdery materials and liquid materials. The horizontal cylinder is axially inserted into the rotating shaft, and a plurality of grinding discs, rings or pins are radially mounted on the rotating shaft. The cylinder is filled with a grinding medium having a particle diameter of 0.6 to 2 mm. The cylinder is provided with a jacket, and the cooling water is passed in the middle to absorb and remove the heat generated during the grinding and dispersing process. The material is pumped into the cylinder, and is strongly stirred by the grinding disc which is rotated at high speed together with the grinding medium. The disc is thrown toward the cylinder wall and returned, and the slurry flow reciprocates between the discs, so that the solid material is gradually dispersed evenly in the liquid material. in. The discharge method varies with the viscosity of the material. Generally, the suspension can be discharged through a screen having slitted holes having a width of 1/2 to 1/3 of the grinding medium. Grinding medium, Zui initially uses sand, so it is called sand mill; after that, it uses glass beads, so it is also called bead mill. Grinding media currently used include: rounded round sand, beads made of various glass or wear resistant materials, steel balls and steel scraps.
