1. "Use the water in the tank to generate electricity, then use the electricity to pump the water back to the tank. The generator and pump will then continue to run forever. Is this possible and why?"
Impossible. Violates the second law of thermodynamics. . .
2. The engine usually dissipates heat through the radiators, and sometimes it is cooled by water flowing over the radiators. Why is it cooled by water?
Water has a large specific heat capacity and is suitable for cooling. . . In fact, we will also use some coolants with a higher specific heat capacity than water for cooling.
The temperature of the cooling water is relatively high
(1) It is generally caused by the accumulation of dust on the radiator outside the water tank cooling. In case of heavy dust, debriss on the outer surface of the radiator or during operation of the device will be drawn into the water tank by the cooling fan, causing blockage, blocking ventilation and resulting in poor heat dissipation. At this point, you just need to clean the radiator outside the water tank and clean the debris from the device to resolve the problem.
(2) After being used for a long time, the generator cooling fan connection belt will gradually age and become easily broken or inelastic, resulting in abnormal blowing capacity. At this point it is necessary to replace the damaged belt. When replacing, all belts should be replaced together instead of just one.
(3) The coolant content is very low. It is necessary to check the factors causing the lack of cooling watert. Check the tightness of the cooling water tank and each cooling water pipe. In the event of a leak, it must be repaired immediately. Then add enough coolant.
(4) The use of a coolant that does not meet the requirements causes the accumulation of scale, rust and other substances in the cooling water pipes, resulting in impedes the circulation of cooling water and causes an increase in water temperature. Coolant is usually water and antifreeze or water and anti-rust fluid. The pH value of water should be between 6.0 and 8.02_, and pure water is generally used. For cooling systems that have been seriously deposited and clogged, it is best to add 0.5L of detergent for every 7L of cooling system volume, mix it with clean water, startthe machine and run it for 90 rain, circulate the cooling water to clean. then use clean water to circulate it Xian to prevent the cleaning agent remaining in the pipe from causing pipe corrosion.
