* Consider the case of a reverse wave from B to A (Figure 14-5,a): Figure 14-5. Diagram of establishing the equation of the water wave chain. Section AA is on the turbine side, section BB is on the lake side, a distance l apart. The water pressure at the beginning of the period is line (1) which is ...
Generators, power transformers and auxiliary equipment in the factory, in the machine room often use bridge cranes. In addition to the main machine room, often use gate cranes or other types of cranes such as winches, hydraulic jacks. placed on site. The water intake and discharge pipes are also ...
Is expanded. From this, it can be seen that the propeller turbine should not take on much changing load, because with that working mode, the propeller turbine works with low efficiency. The real gas iso-coefficient curves of rotary turbines have much larger values Compared with shaft turbines, ...
Lowest water level min in tank appears in unstable working mode When increasing the load of the TTĐ, when (Z - 1) units are working, increase the last unit to full load. If the water level symbol in the tank when (Z - 1) is working at full load is z 1 , and the pressure drop (figure ...
