How to repair the mechanical seal of WRY hot oil pump, the specific method is as follows.

1. Inspect and address various components of corrosion, friction, wear or damage.

2. Remove the seal and throw away the following components: carbon/graphite face. Elastomers and gaskets. spring or spring. Set screws. Any driver lugs or anti-rotation pins. Cracked or damaged bellows. Cracked or damaged mechanical surfaces.

3. Clean the rest of the components, such as sleeves, mechanical seal adapters, etc.

4. Check and clean the components of the Changzhou Wuying Hot Oil Pump to ensure their original size, tolerance, and finish.

5. Some metal carbon fiber composite materials, which must be stress relieved, remove the stress of the finished product after assembly, will prevent remaining flat carbon during storage and transportation. If you're going to carbon insert a metal bracket, you'll have a better push for his engagement with the shaft.

6. Only use components that have been reassembled with new parts provided by the manufacturer. Be sure to use original equipment parts, mechanical shaft seals as many seal manufacturers have created component designs from 'finite element analysis' or similar techniques. SSD faces can be damaged if they are not damaged in any way. Plated or painted surfaces must be stripped and ground before re-plating.

7. Check the flatness of the assembled seal. A vacuum check should be performed on moving components to ensure that there are no leak paths in or around any components. If you choose to check the cartridge for the double seal air test, avoid immersing the seal in water. If the seal is installed behind hot oil or similar applications, water trapped in gaskets and small cracks can flash steam pressure which can be a hazard.
