Sep. 30, 2019

On Sept. 6, 2019, two Owner Representatives and one Swiss Supervisor of the Serbian Power Station Project, paid a second visit to Getai Hydropower, accompanied by relevant leaders of Nari Group, for the FAT inspection and testing of relevant products made for S9- Sveta Petka and S11- Temac. Sveta Petka Station consists of 3 Francis turbine units, each adopting the double runner structure, and its main products include Francis runners, distributors, shaft, governor, draft conical pipe, etc. Temac Station also consists of 3 Francis turbine units, inlcuding 1 set of big machine and 2 sets of small machines, and its main products include Francis runners, spiral case, distributors, conical pipe, etc.


This inspection lasted from September 6 to September 11. During this period, for Sveta Petka Station, the project owner and supervisor performed runner dimension inspections, PT, UT, blade profile inspection, static balancing tests, made action tests on the distributors assembled in the double runner structure, guide vanes clearance inspections at full-close position, guide vane opening inspections, checked and examined the technical processing, surface smoothness, welding and antirust treatment of the whole double runner structure, and communicated with Technical Director of Getai, Mr. Liu for some technical issues; for Temac Station, they performed the runner dimension inspections, PT, UT, blade profile inspections, and distributor action tests, guide vanes clearance inspections at full-close position, guide vane opening inspections, etc. respectively for the Big Machine and Small Machine, and made accurate measurements on the length, inner diameter and outer diameter of conical pipe.


The Swiss supervisor continued his rigorous working manner as last time. During this inspection period, he made inspections while recording the results at the same time, then and compared them with the data provided by Getai Hydropower in the inspection report in order to confirm that the measured values were within a reasonable range of tolerance, and for some inspections, he made tests and measurements himself to ensure the product accuracy and quality.


This inspection is still strict, but each inspection task is completed in a better and more cooperative way. This is due to the fact that Getai Hydropower has accumulated sufficient experience from the previous quality inspection, and on the other hand, because product quality, processing techniques, document and report preparation have improved a lot. It is just because of the above factors in combination with the hard work of Getai people that all products manufactured for S9 and S11 are inspected by the supervisor as accepted in this quality inspection.


In the dinner on the evening of September 11, the project owners sincerely thanked Getai Hydropower for its active cooperation and warm hospitality. They also expressed to believe that the next inspection of S12 in a few months later will still be a successful one, and expected to further strengthen cooperation with Getai Hydropower!
