Engineering machinery engine vibration Vibration and dry sound pollution are two major construction machinery at work. The engine is a mechanical engineering major source of vibration. Propagation engine vibration directly affects the construction machinery machine reliability and service life, little digging machine prices, deterioration of the driver but also to comfort, reduce work efficiency, it must take some effective ways to reduce vibration. Vibration control of the local oscillator control throughout the design, manufacturing and the use of the whole process, reflected in the balance of properties such as improved engine, dynamic performance, precision machining and assembly of parts and so on. A vibration of the engine at work is diverse, for two main reasons: the center of gravity of the engine periodically moved up and down along the cylinder reciprocating member acting inertial force, centrifugal force rotational movement of all parts of the gas pressure alternation caused by rotation of the crankshaft cycle change. These unbalanced forces and moments usually by changing the engine design parameters to adjust the result of the natural resonance frequency of the system to avoid the structure, improve the resonance characteristics of the system, such as through the body modal analysis and finite element calculations to study the body's natural frequency of vibration mode and so on. Weaken machine vibration source and avoid resonance should first consider the design phase, to run through the system in the overall design engineering thinking, Henan digging machines, full application of modern design methods, such as finite source design, reliability design, robust design, optimization design, computer-aided design and intelligent systems and expert design system. When 泰安嘉 and Heavy Machinery Co., Ltd. excavator fuel 1. The rotation angle of the secret minimum operating load to the truck, if the rotation angle, then move large loads, digging machine price list, the cycle time increases. Small angle less the loading cycle time and increase the amount of work per unit time, fuel efficiency is improved. Sometimes the terrain is limiting, as far as possible away from the excavator truck on a non-local 2. Engine running full throttle the engine speed is high, the walking speed, high rotating part, fuel consumption and more. When the engine speed is low than high speed walking while walking better fuel efficiency. The other is the attention to regular maintenance on time, due to the deterioration of oil and diesel filters incomplete fuel injection and lubrication systems will cause damage, leading to excessive consumption of fuel means walking: Cleaning on muddy dirt walking devices, increase the resistance when walking, become increased fuel consumption reasons, try to clean out the dirt. Adjusting the tension of the tension of the track is not properly adjusted, increase the resistance when walking, become the cause of increased fuel consumption, make adjustments based on the adjustment method decoration manual.泰安嘉 and Heavy Machinery Co., Ltd.
