有時(shí)候我們所住的地方周圍會(huì)有正在施工的聲音，其中自動(dòng)攪拌車工作時(shí)的聲音尤其的明顯，噪聲非常的大，那么自動(dòng)攪拌車工作時(shí)的高噪聲怎么產(chǎn)生的呢？有沒有什么辦法能夠處理一下？

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?

當(dāng)攪拌車上料系統(tǒng)把石子、沙、水泥、水按一定比例送入攪拌機(jī)錐形攪拌筒攪拌時(shí),沙石之間、沙石與筒壁之間相互摩擦、撞擊,激起筒壁大面積的振動(dòng)并產(chǎn)生攪拌噪聲。大面積的振動(dòng)不但輻射低頻噪聲也輻射高頻噪聲,攪拌機(jī)撞擊噪聲約為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).

當(dāng)石子、沙和水進(jìn)入攪拌筒開始攪拌時(shí),噪聲大,加入水泥時(shí)噪聲略有下降。另一方面在動(dòng)力的傳輸中,皮帶與皮帶輪之間、齒輪之間在滾軋過程和滑動(dòng)過程中接觸面不平衡摩擦產(chǎn)生的噪聲約為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).

上述由固體振動(dòng)產(chǎn)生的為機(jī)械噪聲,是攪拌機(jī)主要的噪聲源。其電機(jī)噪聲相對(duì)較小,約為85)左右。攪拌車通常露天安裝,該設(shè)備沒有任何隔音、消音措施,其噪聲向外擴(kuò)散遠(yuǎn)達(dá)百米之外。同時(shí)日曬雨淋會(huì)導(dǎo)致傳動(dòng)部件銹蝕或缺少潤(rùn)滑也加劇了機(jī)械噪聲。這眾多的噪音產(chǎn)生因素都是迫切需要的。

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.

1、濾芯堵塞造成吸油困難或不足；清洗或更換濾芯。

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；更換低粘度的液壓油。

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，油面上空氣被吸入泵內(nèi)；補(bǔ)加相同標(biāo)號(hào)的液壓油。

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、吸油管路進(jìn)氣或堵塞；檢查擰緊，不要吸進(jìn)空氣。

4. Intake or blockage of oil suction pipeline; Check the tightening and do not breathe air.

5、自動(dòng)攪拌車的安裝支架的剛性不足，工作時(shí)會(huì)產(chǎn)生震動(dòng)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、輸入法蘭與萬(wàn)向傳動(dòng)軸的連接、萬(wàn)向傳動(dòng)軸與取力器的連接角度過大、松動(dòng)時(shí)會(huì)產(chǎn)生噪音；檢查緊固。

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、自動(dòng)攪拌車罐體內(nèi)有粘結(jié)的混凝土存料，要清鏟干凈。

7. There is bonded concrete stock in the tank of the automatic mixer, which should be cleared.

當(dāng)我們的自動(dòng)上料攪拌車在使用過程中，如果出現(xiàn)噪音的話，應(yīng)仔細(xì)檢查其產(chǎn)生的原因，并采取相應(yīng)的措施，在平常的使用中也要做好對(duì)車輛的維護(hù)以及保養(yǎng)工作，能夠有效避免各種故障的發(fā)生。更多相關(guān)的事項(xiàng)就來網(wǎng)站http://jackpetty.net咨詢吧。

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.
