Pumps and auxiliary equipment for the Ohbagawa Jyoryu drainage pump station

摘要

Ebara pumps and auxiliary equipment had been delivered to and installed at the Ohbagawa Jyoryu Drainage Pump Station, Saitama Prefecture. The drainage capacity of this large-scale pump station, currently 40 m{sup}3/second, will be extended to 60 m{sup}3/second when this pumping station will be fully completed. This pump station has been planned and is run by Saitama Prefecture as a measure against floods in the low plateau area around Misato City, Eastern Saitama. The main pumps comprise Φ 3000 (1 set) andΦ2000 (2 sets) pumps and these are driven by diesel engines. The monitoring and control of pump operation is done semi-automatically to reduce the work load on operators.
