Introduction
Tetsuji Kasatani is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of pump technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and safety of submersible pumps and sealing systems.
Latest Patents
Kasatani's latest patents include a purge apparatus and a sealing system for pumps. The purge apparatus is designed to prevent air from being entrained when a submersible pump is moved into a pump column. It also warms the submersible pump when it is removed from the pump column, preventing the liquefaction of gas and its subsequent emission into the atmosphere. This innovative apparatus features a hermetic purge container, a vacuum line connected to a vacuum source, a purge-gas supply line, and a purge-gas supply valve.
The sealing system relates to pumps that pressurize volatile liquids, such as liquid ammonia. It includes a stuffing box that forms a barrier chamber and a pump-side seal chamber. A mechanical seal is arranged in the barrier chamber, along with a barrier-gas supply system that maintains a pressure difference between the barrier chamber and the pump-side seal chamber. This design enhances the safety and efficiency of the pumping process.
