The groove seal for the end cover of the generator unit of the thermal power plant is sealed, the steam end and the excited end seal seal hydrogen gas, the plane seal of the hydrogen of the outlet hood and the sealing of the stator line casing pipe. At present, most of the turbogenerator units in China, including 1000MW units, 600MW units and 300MW units, use this sealant. The end cover of the turbogenerator seal is sealed with hydrogen.
Excellent performance
HDJ892 slot groove Sealant has a low density and is not affected by water, oil, gasoline, glycerin, steam, gas, steam and exhaust gas. Withstand extreme temperature, do not harden, keep effective seal, shockproof, easy to remove and adjust during maintenance. Prevent from corrosion and "freezing" with metal parts. The seal is not subject to temperature change.
Usage method
1. Wipe the surface before use, clean the sealing groove in the end cover and keep it dry.
2. Before wearing the rotor, the outer cover test is carried out first. The gap between the horizontal and vertical middle section shall be checked. When the tight 1/3 bolt is in condition, it should be checked with 0.03mm feeler.
3. Before sealing the outer cover, it should be pre packed and slot groove Sealant HDJ892 in the joint sealing groove, then evenly tighten the bolts. A special glue injection gun is used to fill the sealing groove by sealing the The groove seal for the end cover of the generator unit of the thermal power plant is sealed, the steam end and the excited end seal seal hydrogen gas, the plane seal of the hydrogen of the outlet hood and the sealing of the stator line casing pipe. At present, most of the turbogenerator units in China, including 1000MW units, 600MW units and 300MW units, use this sealant. The end cover of the turbogenerator seal is sealed with hydrogen. through the injection tube.
4, glue injection method: choose a glue hole to start slowly and pour out in the adjacent hole. Inject in turn until it is full.
5. Uniform injection and drain the gas in the tank to avoid false filling.
6. Diluents are not allowed.
