On June 8th, the Development and Reform Commission released news that the price of oil has risen. The domestic refined oil products have achieved a "four consecutive rise," and the price of gasoline and diesel has risen by 110 yuan per ton. According to this calculation, each time you add more money to a few dollars, and under such a big situation, many garbage truck owners are rather troublesome. A few days later, the small standard will give you some tips on fuel-efficient garbage trucks:
Do not think that the swing arm garbage truck will not be maintained, and the car will no longer be repaired. The regular maintenance of the car can not only reduce the probability of failure of the car but also reduce the fuel consumption of the car. In the maintenance of the locomotive, some regularly replaced equipment can not be changed, like spark plugs, oil filter (oil filter), transmission oil, etc., only to keep the vehicle in the best condition, can the car give Let's hand out the best fuel consumption.
Do not press the accelerator pedal with your right foot. Many garbage truck drivers like to step on the accelerator very strongly. Maybe they believe that "there is a miracle." But Xiaobian tells you, you can shorten the percentage by 4 percent when you step on the throttle. At the time, it increased fuel consumption by 37 percent. Generally in urban roads, the most fuel-efficient hourly speed is around 50 kilometers per hour. The speed of the engine is maintained between 2,000 and 2,500 rpm. On high speeds, it can be between 90 and 100 kilometers per hour. Why not start soon? Because every 10 kilometers increase, the fuel consumption will increase by 10%. If your garbage truck has the function of cruising, you can open it again at high speed, which can effectively avoid the unstable rotation speed and bring the burden on the engine. Do not slam the brakes and accelerate quickly while driving. The driver's observation range should be a bit farther. If the traffic jam or signal light is ahead, it is best to prepare the brakes in advance.
Giving weight to the car is also a very good way to reduce fuel consumption. If the garbage truck does not run long distance, you can not fill up the tank because the load does not increase fuel consumption by 1 kilogram. It is also worth noting that many old drivers like to go downhill to save fuel, but this is a very dangerous behavior and it is not safe without engine braking. The above is a brief introduction to the fuel saving method of garbage trucks. (Wen/Jun Xun)
There are three basic types of fixed bed reactor: (1) axial adiabatic fixed bed reactor. The fluid flows through the bed along the axial direction, and there is no heat exchange between the bed and the outside world. (2) radial adiabatic fixed bed reactor. The fluid flows through the bed along the radial direction. Centrifugal flow or centripetal flow can be adopted. There is no heat exchange between the bed and the outside world. Compared with axial reactor, radial reactor has shorter flow distance, larger cross-sectional area and smaller fluid pressure drop. But the structure of radial reactor is more complicated than that of axial reactor. The above two forms are adiabatic reactors, suitable for the reaction heat effect is not large, or the reaction system can withstand adiabatic conditions caused by the reaction heat effect of the temperature changes. (3) The tubular fixed-bed reactor is composed of multiple reaction tubes in parallel. The catalyst is arranged in the tube or between the tubes, and the heat carrier flows through the tubes or tubes for heating or cooling. The diameter of the tubes is usually between 25 ~ 50mm, and the number of tubes can be as many as tens of thousands of roots. The tubular fixed bed reactor is suitable for the reaction with high thermal effect. In addition, there is a reactor composed of the above basic forms in series, called a multistage fixed bed reactor.
