Maintenance of HEPP

Datek Enerji Group, is monitored the increasing importance of hydroelectric power plant investment in our country and the world. We struggle with close the deficit of knowledge and experience in these working environments.

Turkey’s most important capital owners and fundamental organizations gain Access to invest far requirements of the cheapest energy. Considering cost and efficiency, our company offer both For Eastern origin of manufactures and the European orijin of HES projects.

Energy production, as a multidiciplinary area, is sustained in safe and effetive by the quality control and guarantee companies. Our company, in this context has a lotof contact with domestic firms. These firms are continuing their marginal benefits of investment criteria within the framework of HEPPs.

Our Company, as a international controlling association, implements international quality control rules to help the investors obtaining better power plants. Besides our company, during assignments in this working environments, has co-operators and these relationships introduce us to wider working frame.

We took part in China for fulfilling quality control and testing activities about 9 HEPPs. Within the framework of this study, we warn investors with our paper work about possible future problems. About elecromechanic and hydromechanical productions, we have strong organization structure.

Here are some samples of our test and quality control lists about turbines and generators.

1- Quality control tests during manufacturing
2- Preparation before shipping, overseas shipping norms within the framework of the packaging.
3- During the end of the manufacturing, checking the compatibility of various parts.
During the establishment of the assembly for turbine-generator equipment, in the field; especially cheching the lubrication oil and cooling water equipments and air tank pressures on oil-water seal up to hydrostatic pressure experiments.
5- Upon completion of installation of equipment, preparatory Works, examinations and documentation of experiment.
6- Opened the facility in operation within the warranty at any time that maybe related to final acceptance
7- Checking all parts of turbines and generators
8- Tests and examinations, the generator bearings modifying, generators chemicals and cleaning, checking the windings.
