Stirring kettle mechanical seal
Thread Content
The reaction stirred kettle, the material is relatively acidic, currently uses a single-end mechanical seal, and there is oil leakage. When the shaft rotates, the oil will be brought out and flow to the kettle lid. How to solve it, whether corrosion-resistant double-end mechanical seal can be used.
Use cartridge sealing and thermosiphon circulation coolant. Consider whether the floating roof structure has a structure and space that can fix the seal.
Air-cooled mechanical seal can be used without oil or water for lubrication.
Glass-lined mixers often have problems with large shaking amplitudes, so stainless steel mechanical seals often cannot be used in such equipment. This is not only a cost issue.
1. From this position, you can install double-end faces to take a look. It is recommended to ask a professional mechanical seal manufacturer to measure and map it for you. 2. When installing the machine seal, check whether it is an installation problem. Make as few changes as possible.
Do not change the seal, increase the height of the enclosure, and then connect a return pipe to collect waste liquid. There is nothing wrong with your seal selection. Recommendation 1: Before seal procurement enters the factory, please ask the manufacturer to assemble and test run or inspect the parts for acceptance through aperture. 2. If the mixing shaft shakes or jumps, check it during maintenance.
Add a half lid to the height of the liquid joint. Add a sight glass or use acrylic as the lid directly so that you can observe the oil level inside.
