400kva diesel generator,400kva diesel generator engine set for sale

Within Shajiao C Power generator cooling water treatment is used Xiaohun bed manner, since the cold water system and the presence of the treatment system design, installation defects, run the test data shows that although the national standard and specified by the manufacturer within the generator cold water conductivity can basically meet requirements, but the inner cooling water p H value of long-term instability. January 2000 within Shajiao C Power Plant No.1 generator cold water pH value between 8.06 ~ 8.64, February p H value between 8.06 ~ 8.23, June 2001 pH value between 6.08 ~ 8.76 (running , the No. 2 generator and the generator within 3 cold water pH value not stable), can not meet the national standard indicators, the presence of acid corrosion system security risks. 4.2 Shajiao A 200 MW unit generator cold water system structure and operating conditions

Shajiao A 200 MW unit generator inner cooling water system in the cold water also from inside the cold water tank, internal cooling water pump, cooling devices, filters and ion exchange cation bed composition, but the system's sun-bed ion exchange process is supplemented demineralized water, within the closed cycle for generating cold water could not be processed, when the cold water conductivity or pH value of failure, through the drain, fill demineralized way to make cold water conductivity and p H value qualified.
