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, but also to deteriorate driver 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 engine center of gravity moved periodically, the price of used mini excavators, the reciprocating member along the cylinder up and down action of the inertial force, centrifugal force all rotating moving parts, small Taiyuan excavators, gas pressure alternation cycle changes caused by rotation of the crankshaft. 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 Wait. Weaken machine vibration source and avoid resonance should first consider the design phase, to run through the whole system design engineering ideas, 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 system design.泰安嘉 and Heavy Machinery Co., Ltd. Notes 1,250h excavator regular maintenance inspection and maintenance inspection on the filter cleaner attachments, such as metal powders excessive, often marking the oil pump wear or cylinder pull cylinder, which must be confirmed and take After the appropriate measures in order to boot. If found damaged filter, dirt accumulation, should be replaced, while oil change if necessary. 2.500h inspection and maintenance no matter what condition the filter should be replaced, because small damage difficult to detect with the naked eye filter, if prolonged high-temperature operation should be sufficiently in advance to replace the filter. 3,1000h inspection and maintenance cleaning filter, replace the filter, used mini excavators, hydraulic oil tank cleaning, replace the hydraulic oil. Long-term high-temperature operation oil change should be appropriate in advance. Of course, such as through the oil quality testing analysis to guide the oil change is the most economical, but be careful to extend the use of oil, should be tested once every 100h, in order to detect and replace the bad oil. 4,7000h 10000h inspection and maintenance of the hydraulic system must be detected by professionals, make the necessary adjustments and repairs. According to the practice, import hydraulic pumps, hydraulic motors must be overhauled after work 10000h, otherwise hydraulic pumps, motors may be damaged due to disrepair, the hydraulic system is to destroy life in nature.泰安嘉 and Taiyuan Heavy Machinery Co., mini-excavators and heavy _ _ Ka mini excavator farm prices by 泰安嘉 and Heavy Machinery Co., Ltd ..
