– Hwashin Bolt Industries is carrying out research and development projects aiming to develop new products
and improve productivity in order to meet various customers and environment changes.
– Developed Product : Compressor Rotor Bolt.
- A component that penetrates and fixes a high-temperature, high-speed rotating compressor disk.
- The highest value of the highest value added turbine components.
- Stability and quality are very important, and customer’s quality requirements are very strict.
- Precision machining technology for hard metal, long axis concentricity
/ straightness securing technology, surface treatment technology, Complex technology such as quality inspection technology is required.
Existing Mechanical Seal
- Assemble the perturbation part on the rotating shaft in the axial direction
- Disassemble the entire rotating device when replacing after a certain period of use.
- Increase maintenance time / cost
Separate Mechanical Seal
- Pivoting parts on the rotating shaft are assembled from both sides
- Easily disassembled and assembled when replacing (Maintenance time, cost reduction)
Excellence and differentiation of development technology
No need to disassemble the entire pump for mechanical seal replacement.
Replacement time: 10 ~ 12 hours -> 1 hour
More than 90% cost savings
