Add 100, add 200, top up... Refueling your car is the most common thing that car owners do. But you don't know that, as the biggest expense for driving a car, there is a university to ask about refueling! Learned the following things that will save you at least 20% in fuel costs per month. Calculate how much money you spend. The first move: the best province in the morning and evening Gasoline is billed by volume, not by weight, and the temperature during the day is high. Especially during the summer, the volume of gasoline will be affected by temperature and expansion and contraction. When you refuel in the morning or evening, the same volume of gasoline can have more quality, and you can save a small amount of money after a long time. Similarly, winter refueling is more cost-effective than summer refueling. In fact, the most cost-effective refueling time should be midnight, but Xiao Bian really does not believe that someone will go back and do so. The second measure: Do not say how much money added Don't spend money on how much money, you often lose your money virtually. Because the amount of money you have to add will be rounded up when the tanker arrives. When you go down several times, you will not be worth it. Think of a tanker like this is a bit embarrassing! The third measure: Try not to fill up for refueling There is a prerequisite for refueling as little as possible, that is, you will only run in the downtown area in the near future. Urban driving often stops and stops. If you fill up the tank, you will increase the load on the engine, make you unable to start and fuel the vehicle. And so many gas stations in the city, you can still be afraid of your car without oil! If you run downtown, please fill half or 2/3 of the fuel tank to get the most fuel. The fourth move: choose to rely on gas station Relying on gas stations is not only familiar PetroChina and Sinopec, but also some foreign companies' gas stations. Of course, this is still rare in China. The greediness and the gullibility of those so-called low-priced gasolines are not a long-term solution. When vehicles really have problems with oil products, they have no regrets. The fifth measure: Do not be lazy! To refuel in time Don't wait until the light comes on! Even if the indicator of the oil gauge shows that it can run, it should be immediately refueled. If the fuel tank is short of oil, it will cause the oil pump to burn out and shorten the service life of the oil pump. The above points, although they do not seem to save much, but you do all this, save at least 10% to 20% of the oil costs each month! Shell and Plate Heat Exchanger
A shell and Plate Heat Exchanger is typical heat exchanger consists of a series of stacked plates and enclosed in a container shell. The plates are arranged in a chevron pattern, with each plate having its own inlet and outlet ports. Heat is transferred between the two fluids as they flow through the plates and shell respectively.
Shell and plate heat exchangers are used in particularly industrial plant. They are those require larger surface area and higher heat transfer coefficient, while at the same time, of high temperature and pressure.
In addition to their efficiency and compact size, shell and plate heat exchangers are also flexible in terms of material selection. Constructing material could be carbon steel, AISI 304, AISI 316L, AISI 904L, 254 SMO, Ti, Hastelloy, and more based on various operations.
Features of shell and plate heat exchanger are:
Gasket free
Stable and safe structure
Special seal structure for preventing media by-pass
High heat transfer efficiency
