R&D Project.

- Hwasin 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.

rnd project

- 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.

Split Mechanical Seal

개발 장비

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

개발 장비 개발 장비

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
