| 1. | The experience in operating and adjusting the ÉGRK-2M and ÉGRK-1T electrohydraulic governors shows that it is possible to considerably improve the characteristics of the control system and to increase the operating reliability of the governors by uncomplicated improvements in the circuit of the floating control component and circuit of the automatic devices. |
| 2. | When designing new control systems and modernizing governors it is expedient to use more fully the experience in operating both hydromechanial governors and preceding modifications of the EHGs. |

Conclusions The use of scuba- and helmet-diving equipment is advisable when inspecting hydraulic structures of hydrostations at depths to 20 m.The use of helmet-diving equipment is advisable when working at depths to 40–45 m. Scuba-diving suits can be used in individual cases.When working at depths exceeding 40–45 m, units with the use of diving chambers are the most economical. Such a unit is being developed at the Siberian Hydraulic Engineering Institute joint-stock company.Translated from Gidrotekhnicheskoe Stroitel'stvo, No. 2, pp. 30–32, February, 1995. 相似文献

| 1. | The relative method of measuring the flow rates of water through a turbine is realized by simple means and provides a sufficient accuracy for the needs of hydrostation operation. |
| 2. | Further works of design organizations, operating services, and manufacturing plants is necessary for increasing the reliability of the entire flow-rate measuring system. |
| 3. | The operating staffs of hydrostations need to be materially encouraged to use the discharge efficiently for producing electricity. |
