簡述裝載機(jī)噪音大怎么辦
來源：http://m.ywsun168.com/ 日期：2023-04-24
伴隨著我國機(jī)械化進(jìn)程的加快，大型機(jī)械化作業(yè)已經(jīng)是整個重工業(yè)的標(biāo)配，裝載機(jī)被廣泛應(yīng)用于各大領(lǐng)域，如道路、建筑、礦山等，主要負(fù)責(zé)對沙土、石灰和礦石粉末等粉末狀物料的挖掘和運(yùn)輸工作，搭配不同的輔助工作裝備，甚至可以進(jìn)行推土、起重等工作，可謂是一臺一起多用。
With the acceleration of China's mechanization process, large-scale mechanized operations have become the standard equipment for the entire heavy industry. Loaders are widely used in various fields, such as roads, buildings, mines, etc., mainly responsible for the excavation and transportation of powder materials such as sand, lime, and ore powder. With different auxiliary work equipment, they can even be used for soil pushing, lifting, and other work, which can be described as a multi-purpose machine.
但其實這么好的設(shè)備，也會存在一點(diǎn)問題，其在作業(yè)時會產(chǎn)生一定的噪音，隨著技術(shù)的不斷進(jìn)步，噪音已經(jīng)可以控制在合理范圍內(nèi)，但是有客戶咨詢我們說近期裝載機(jī)變大，找不到原因，下面濟(jì)南裝載機(jī)租賃廠小編來為大家解決這個問題：
But in fact, such a good equipment may also have some problems. It produces a certain amount of noise during operation. With the continuous progress of technology, the noise can be controlled within a reasonable range. However, some customers have consulted us and said that the loader has become larger recently, and we cannot find the reason. Below, the editor of Jinan Loader Rental Factory will solve this problem for everyone:
要知道，噪音產(chǎn)生的原因主要來源于機(jī)械噪音：
It should be noted that the main source of noise is mechanical noise:
1、由于裝載機(jī)柴油機(jī)上運(yùn)動副很多，所以引起的機(jī)械激振力也很多，其中有活塞與氣缸敲擊產(chǎn)生的噪聲，正時齒輪響聲，燃油噴射系統(tǒng)噪聲，配氣機(jī)構(gòu)噪聲等。
1. Due to the many motion pairs on the diesel engine of the loader, there are also many mechanical excitation forces caused, including the noise generated by piston and cylinder knocking, timing gear noise, fuel injection system noise, and valve train noise.
2、在發(fā)動機(jī)中，曲軸、飛輪、皮帶輪等轉(zhuǎn)動部件中的任何一個都會形成振動力，由于這個振動力與部件的不平衡量成正比，與其每分鐘轉(zhuǎn)速的平方成正比，因此，當(dāng)轉(zhuǎn)速增加時，振動也被急劇放大，所以轉(zhuǎn)動部件之間的平衡量小一些。
2. In an engine, any rotating component such as the crankshaft, flywheel, pulley, etc. forms a vibration force. As this vibration force is proportional to the imbalance of the component and the square of its speed per minute, as the speed increases, the vibration is also sharply amplified, resulting in a smaller balance between rotating components.
其它機(jī)械噪音來自發(fā)動機(jī)活塞、氣門機(jī)構(gòu)等，構(gòu)成了發(fā)動機(jī)噪音的一部分，如活塞敲缸，挺桿噪音，氣門開閉所產(chǎn)生的噪音，氣門和氣門彈簧振動所產(chǎn)生的噪音，以及正時鏈與鏈輪嚙合時產(chǎn)生的噪音。
Other mechanical noise comes from the engine pistons, valve mechanisms, etc., which form a part of the engine noise, such as piston knocking, tappet noise, noise generated by valve opening and closing, noise generated by valve and valve spring vibration, and noise generated when the timing chain engages with the sprocket.
3、活塞敲缸是活塞側(cè)面敲擊缸壁所產(chǎn)生的噪音，當(dāng)作用到活塞上的壓縮壓力轉(zhuǎn)變?yōu)槿紵龎毫r，就產(chǎn)生了敲缸。活塞敲缸因活塞間隙的不同而不同，活塞間隙大時，有可能產(chǎn)生敲缸聲。活塞敲缸的特點(diǎn)是發(fā)動機(jī)冷態(tài)時很響，因此時活塞間隙大，隨著發(fā)動機(jī)的溫升，聲音也變小。
3. Piston knocking is the noise generated by the side of the piston striking the cylinder wall. When the compression pressure acting on the piston changes into combustion pressure, knocking occurs. The piston knocking on the cylinder varies depending on the piston clearance, and when the piston clearance is large, there may be a knocking sound. The characteristic of piston knocking on the cylinder is that the engine makes a loud noise when it is cold, because the piston clearance is large at this time, and as the engine temperature rises, the sound also decreases.
要減輕活塞敲缸，必須減少主側(cè)壓力，因此有些發(fā)動機(jī)將活塞銷的中心與活塞中心線偏離一定距離，即可減少敲缸聲。減少活塞敲缸的另一方法是在活塞裙部安裝鋼架，用以減少活塞裙部的熱變形，從而可使用尺寸略大的活塞，將活塞間隙減小，使活塞敲缸聲變小。
To reduce piston knocking, it is necessary to reduce the main side pressure. Therefore, some engines can reduce the knocking sound by deviating the center of the piston pin from the centerline of the piston by a certain distance. Another method to reduce piston knocking on the cylinder is to install a steel frame on the piston skirt to reduce thermal deformation of the piston skirt. This allows for the use of slightly larger pistons to reduce piston clearance and reduce the sound of piston knocking on the cylinder.
以上裝載機(jī)噪音分析，相信肯定對您有所幫助，發(fā)現(xiàn)機(jī)器噪音異常時，應(yīng)當(dāng)及時處理，先從以上三點(diǎn)開始排查，如果仍然沒有解決，您可以來電咨詢我們http://m.ywsun168.com，我們將為您提供各方面的技術(shù)支持！
The above analysis of loader noise is believed to be helpful to you. If any abnormal machine noise is found, it should be dealt with in a timely manner. Starting from the above three points, the investigation should be carried out first. If it is still not resolved, you can call us for consultation http://m.ywsun168.com We will provide you with technical support in all aspects!
