HDJ892 Generator hydrogen sealing slot sealant

short description:

Generator hydrogen sealing slot sealant HDJ892 is used for groove sealing of end caps and outlet covers of hydrogen-cooled turbine generators in thermal power plants. The sealant is prepared from raw materials and does not contain dust, metal particles and other impurities. At present, domestic steam turbine generator units, including 1000MW units, 600MW units, and 300MW units, all use this sealant.

Product Detail


Before closing the outer end cover of the generator, pre-fill HDJ892 sealing packing in the sealing groove of the joint surface, and then tighten the bolts evenly. Then use a special tool to inject HDJ892 sealant into the sealing groove (glue injection method: select a glue injection hole to start slowly injecting, and then flow out from the adjacent hole. Inject in sequence until all are filled).
