有时候我们所住的地方周围会有正在施工的声音,其中自动搅拌车工作时的声音尤其的明显,噪声非常的大,那么自动搅拌车工作时的高噪声怎么产生的呢?有没有什么办法能够处理一下?
Sometimes there is a sound of construction around the place where we live, especially when the automatic mixer works, and the noise is very loud. So how does the high noise of the automatic mixer work? Is there any way to deal with it?
当搅拌车上料系统把石子、沙、水泥、水按一定比例送入搅拌机锥形搅拌筒搅拌时,沙石之间、沙石与筒壁之间相互摩擦、撞击,激起筒壁大面积的振动并产生搅拌噪声。大面积的振动不但辐射低频噪声也辐射高频噪声,搅拌机撞击噪声约为95)左右。
When the charging system of the mixer truck sends stones, sand, cement and water into the conical mixing drum of the mixer according to a certain proportion for mixing, the friction and collision between the sand stones and between the sand stones and the drum wall will arouse the large-area vibration of the drum wall and produce mixing noise. Large area vibration radiates not only low-frequency noise but also high-frequency noise, and the impact noise of the mixer is about 95).
当石子、沙和水进入搅拌筒开始搅拌时,噪声大,加入水泥时噪声略有下降。另一方面在动力的传输中,皮带与皮带轮之间、齿轮之间在滚轧过程和滑动过程中接触面不平衡摩擦产生的噪声约为87)左右。
When stones, sand and water enter the mixing drum and start mixing, the noise is large, and the noise decreases slightly when adding cement. On the other hand, in the transmission of power, the noise generated by the unbalanced friction of the contact surface between the belt and the pulley and between the gears during rolling and sliding is about 87).
上述由固体振动产生的为机械噪声,是搅拌机主要的噪声源。其电机噪声相对较小,约为85)左右。搅拌车通常露天安装,该设备没有任何隔音、消音措施,其噪声向外扩散远达百米之外。同时日晒雨淋会导致传动部件锈蚀或缺少润滑也加剧了机械噪声。这众多的噪音产生因素都是迫切需要解决的。
The above mechanical noise generated by solid vibration is the main noise source of the mixer. Its motor noise is relatively small, about 85). The mixer truck is usually installed in the open air. The equipment has no sound insulation and silencing measures, and its noise spreads out as far as 100 meters away. At the same time, the sun and rain will lead to rust or lack of lubrication of transmission parts, which also aggravates the mechanical noise. These numerous noise generating factors are urgently needed to be solved.
自动搅拌车
1、滤芯堵塞造成吸油困难或不足;清洗或更换滤芯。
1. The filter element is blocked, causing difficulty or insufficient oil absorption; Clean or replace the filter element.
2、工作油液不合要求或油液粘度太大;更换低粘度的液压油。
2. The working oil does not meet the requirements or the oil viscosity is too high; Replace the hydraulic oil with low viscosity.
3、油箱液面太低,油面上空气被吸入泵内;补加相同标号的液压油。
3. The liquid level of the oil tank is too low, and the air on the oil level is sucked into the pump; Add hydraulic oil of the same grade.
4、吸油管路进气或堵塞;检查拧紧,不要吸进空气。
4. Intake or blockage of oil suction pipeline; Check the tightening and do not breathe air.
5、自动搅拌车的安装支架的刚性不足,工作时会产生震动和噪音;加固支架。
5. The mounting bracket of the automatic mixer is not rigid enough, which will produce vibration and noise when working; Reinforce the support.
6、输入法兰与万向传动轴的连接、万向传动轴与取力器的连接角度过大、松动时会产生噪音;检查紧固。
6. The connection between the input flange and the universal drive shaft, and the connection angle between the universal drive shaft and the power take-off are too large and loose, which will produce noise; Check the fastening.
7、自动搅拌车罐体内有粘结的混凝土存料,要清铲干净。
7. There is bonded concrete stock in the tank of the automatic mixer, which should be cleared.
当我们的自动上料搅拌车在使用过程中,如果出现噪音的话,应仔细检查其产生的原因,并采取相应的措施,在平常的使用中也要做好对车辆的维护以及保养工作,能够有效避免各种故障的发生。更多相关的事项就来网站http://www.jfhntjbc.com咨询吧。
When our automatic loading mixer truck is in use, if there is noise, we should carefully check the cause of it, and take corresponding measures. In normal use, we should also do a good job in the maintenance of the vehicle, which can effectively avoid the occurrence of various faults.
