Inspection items before assembling the mechanical seal of the kettle

Inspection items before assembling the mechanical seal of the autoclave 1. You must check whether the mechanical seal of the autoclave being installed is suitable for your operating range of the mechanical seal. When the temperature of the conveying medium is too high, too low, or contains impurity particles, is flammable, explosive, or toxic, corresponding measures such as sealing, washing, cooling, and filtering must be taken. 2. Check the relevant danger marks, check the installation and connection dimensions of the mechanical seal, check the accuracy of the important axial and radial dimensional tolerances on the shaft and cavity. (The finish of the shaft or shaft sleeve is not greater than 1.6 microns, the tolerance of the shaft or shaft sleeve is h7, the runout of the seal cavity end facing the pump shaft is not greater than 0.015mm per 3cm. The radial runout of the shaft should not be greater than 0.1mm, and the axial run Momentum should not be greater than 0.15mm, the end corner of the'O' ring passing through the sleeve should be smoothly over-chamfered, the shoulder chamfer is 3 × 10 °, and the end cap chamfer is: 2~2.5 × 20 °). 3. Read the mechanical seal assembly drawing carefully (refer to the product catalog for standard series products) to ensure the mechanical seal installation size and tolerance.
