1. Firstly, the air inlet temperature for the supplemental air is high, so cooling water vapor injection is required.
2. Second, using the principle that water has different boiling points under different atmospheric pressure, pour the hot water that has absorbed the heat from the diesel generator into the sealed evaporation tank.
3. Finally, the exhaust gas specially used for injection flows through the nozzle diffuser of the sealed tank and performs high-speed jet deflection and pressure expansion, discharging the cold vapor in the tank, from so that filling and pumping can reach high vacuum, and it continues. Part of the water poured into the tank will vaporize and evaporate under isothermal conditions, then it will release heat at low temperature and become frozen water at low temperature when operating incontinuous. , low temperature cooling water can be produced continuously.
The difference in air temperature between the inlet and outlet of the generator is related to the heat removed by the air and the quantity of air. Additionally, it is also related to temperature and the amount of cooling. water. Under the same load, the temperature difference between the inlet air and outlet air should remain unchanged, which can be compared with previous operating records. If it turns out that the wind temperature difference increases, it means that the internal loss of the generator has increased or the air volume has decreased. It should be paid attention to and the reasons should be checked and analyzed.
A sudden increase in generator internal loss may be due to a disconnection of a welding head somewhere in the stator winding, damage to the insulation between the strands, or a local temperaturethe high in the nucleus. The reduction in air volume may be due to reasons such as the cooler or air duct being clogged with dirt.
