Shanghai Xuhui Shaanqi Huaying _ [quote] _ dump dump Xuhui Shaanqi provided by Shanghai Huaying. We are Shanghai Huaying Shaanqi Automobile Sales Co., Ltd. (www.huaying.com) in: Shanghai Baoshan District, specializing in: SHAC, tractors, trucks, special vehicles, such as dump trucks precautions: We advocate for self- unloading the car and dump truck unloading operations, to develop the following precautions: 1, make sure the vehicle is in good technical condition, such as the lift cylinder and top parts of the firm solid, compartment floor flat, flexible and reliable since the lock switch. 2, the driver of the dump truck stop material loading operations, make sure to stop loading and overloading the average charge. 3, when the driver selects unloading sites, try to choose a flat solid place. 4, Xuhui Shaanxi Auto dump truck driver stopped lifting job quote to the proper speed to stop lifting, to prevent large throttle speed lift. 5, regular application loaders and other machinery for unloading place to stop leveling and compaction. Shaanxi Automobile fuel Delong F3000 principle engine Shaanxi Automobile Delong F3000 when neutral slide left foot accelerator pedal, the engine speed will quickly drop to idle speed, throttle position sensor detects this signal and transmitted to a computer, the computer will follow the design of the idle conditions injector fuel injection pulse width control the engine at idle speed. Foot off the accelerator pedal when with a sliding block, due to the anti-drag effect Shaanxi Automobile Delong F3000 engine speed with the decline in the speed of a slow decline in Xuhui Shaanqi dump prices, there is a process. Engine speed is between low-speed and high-speed point off the oil off the oil-point speed at which the throttle position sensor detects the position of the throttle valve is fully closed, meaning that the computer detects that the throttle is in the idle condition, Xuhui by the throttle position sensor Shaanxi Auto dump truck plant, but Shaanxi Automobile Delong F3000 speed was higher than the design requirements idle speed, so computer-controlled injector fuel injection is stopped. With the speed of the lower engine speed also dropped Xuhui Shaanxi Auto dump truck, off the oil when it reaches the low point fuel injection nozzle is controlled by computer recovery in the oil phase if necessary to stop the acceleration, simply depress the accelerator pedal to re- oil recovery, so Shaanxi Automobile Delong F3000 vehicle speed driving. By stopping the fuel injection nozzle to save fuel and improve fuel economy.
