Title: Hiroshi Ohmachi: Innovator in Multistage Compressor Technology
Introduction
Hiroshi Ohmachi is a notable inventor based in Shimoinayoshi, Japan. He has made significant contributions to the field of multistage compressor technology, holding two patents that enhance the efficiency and control of compressor systems. His work is recognized for its innovative approaches to capacity control and energy consumption.
Latest Patents
Ohmachi's latest patents include a "Method of capacity controlling of multistage compressor" and an "Apparatus." This invention focuses on controlling the capacity of a multistage compressor in response to a flow rate signal by varying the openings of vanes at individual stages. The relationships of the openings of the vanes are adjusted based on the flow rate signal, allowing for optimal efficiency when the compressor operates far from its anti-surge capacity. Additionally, when the flow rate approaches the inoperable range, the invention enables adjustments that expand the operating range of the compressor.
Another significant patent is the "Method of controlling multistage centrifugal compressor equipment." This method involves controlling the operation of multistage centrifugal compressors equipped with inlet guide vanes and diffuser vanes. It aims to achieve low energy consumption by determining the prevailing flow rate and adjusting the operation of the guide and diffuser vanes accordingly. This approach ensures that the compressor operates efficiently, whether the flow rate is near the desired level or not.
