Inspection items before assembly of mechanical seal for kettle
1. It is necessary to check whether the installed mechanical seal for the kettle is suitable for your mechanical seal operating range. When the temperature of the conveying medium is too high, too low or contains impurity particles, flammable, explosive or toxic, corresponding measures such as blocking, flushing, cooling and filtering must be taken. 2. Check the relevant danger signs, check the installation and connection dimensions of the mechanical seal, and check the accuracy of the important axial and radial dimensional tolerances on the shaft and the cavity. (The smoothness of the shaft or the shaft sleeve is not more than 1.6 microns, the tolerance of the shaft or the shaft sleeve is h7, and the runout of the seal cavity end facing the pump shaft is not more than 0.015mm per 3cm. The radial runout of the shaft should not be more than 0.1mm, and the axial runout Momentum should be no more than 0.15mm, and the end corner of the 'O' ring passing through the shaft sleeve should have a smooth and excessive chamfer, the shoulder chamfer is 3 × 10 °, and the end cover chamfer is: 2~2.5 × 20 °). 3. Carefully read the mechanical seal assembly drawing (for standard series products, please refer to the product catalog) to ensure the mechanical seal installation dimensions and tolerances.
