Cartridge Seal Repair
Two 72mm Burgmann cartridge seals sent in to Robco of America’s Texas repair facility for failure analysis and overhaul under emergency basis. These seals came in from a chemical plant in Pasadena Texas. End user stated the seals operated for 6 months before failure. Upon inspection it was found that the Silicon Carbide rotary seats cracked close to the drive pin slots. Robco re-designed the drive pin slots to allow for an increased radial wall thickness around the slots to reduce the risk of future failure. New Silicon Carbide seats were produced in 4 working days.
In between time Robco machined new Carbon stationary seal faces that had a 20% wider lapped face. Reason for this modification was due to carrying out a stress analysis on the seal faces under operating conditions which found the Carbon faces were generating too much face load against the rotary Silicon carbide seal seats. The o’ring sealing surfaces in all the metal parts were polished to 32 RMS finish or better. Seals re-assembled and pressure tested to 60 PSIG for 20 minutes? no pressure drop.
Assembly Seal Repair
28mm double seal assembly + 2 shaft bearings sent into Robco repair facility for failure analysis & overhaul.
John Crane seals sent in for repair from oil refinery
Double Beadmill Seal Repair
Below are pictures of an 80mm Double Beadmill seal sent to Robco for Failure Analysis & repair. Upon inspection we found that the product side springs were not supplying sufficient seal loading force compared to the process pressure in customers mixing tank. This allowed the product to leak passed the inner end seal faces which in turn put excessive loading on the rotary Tungsten face causing it to crack.
Robco installed stiffer springs to get an acceptable seal face load that could handle the process pressure. We replaced broken Tungsten seat & re-machined & polished all metal parts on o’ring sealing surfaces. Seal was re-assembled & pressure tested to 100 psi. Seal is back in service & has been on-line for 18 months with no leaks.
