Driving a car in Tibet to travel to Tibet is definitely not the same as tourism in the plains. How much is there to be some simple "vehicle altitude response" for the vehicle? Especially for those who use gas, the more they drive to those In areas with higher altitudes, there are certainly some minor problems. This is not something to worry about. When a water heater is used in high altitude areas, it is one of the facilities that will encounter problems. For example, when the lights are turned on, the water heaters of the inhabited cars will stop working at the same time. It will be very embarrassing to bathe half the water in the shower and all that needs to be done now is to put the car in the window of the car or The door is slightly open so that a small gap, so that there is enough air to enter the car, you can restore the use of water heaters. According to a friend of a RV driver, when they drove the RV to high-altitude terrain tourism, occasionally the refrigerator would not operate. Initially, it was thought that the refrigerator had a malfunction, but it was driving to a lower altitude. After the location, the refrigerator can be used normally again. If the refrigerator in the high-altitude residential vehicle does not work, then the energy supply of the residential vehicle can be adjusted from the fuel gas supply to the external power, and the problem can be resolved immediately. There is also the problem that many people have headaches when traveling at high altitudes. That is, the generators of the vehicles are not operating properly under such circumstances. The most serious is that sometimes the engine cannot be started at all. Because in those areas where the altitude is higher, the air pressure will be very low, and the oxygen contained in the thin air is relatively small, resulting in the normal use of the generator. In the face of such a situation, it should effectively avoid its overloaded operation, can use exhaust gas turbocharger to achieve high altitude power compensation effect, use low-temperature start phase-assisted start-up measures, and then Use a pressurized closed cooling system to boil the boiling point of coolant at high altitude.
There are many problems in the recovery of copper chips directly into the furnace, the recycling of copper brass chips reduces the production cost of foundry enterprises and greatly improves the market competitiveness of the enterprises. The copper scraps are small, loose, directly into the furnace will be seriously blocked, the material block clearance is the furnace gas rising channel, directly affect the smelting process, the loose steel scrap without pressing, extremely easy to float on the furnace lining, corrosion lining, and large loss of raw materials will cause low molten iron rate.
