很多人聽(tīng)到混凝土攪拌機(jī)在運(yùn)行過(guò)程中出現(xiàn)異常的聲音不會(huì)很重視，這就陷入了一個(gè)錯(cuò)誤的誤區(qū)，往往會(huì)造成機(jī)械設(shè)備的損害，那么混凝土攪拌機(jī)出現(xiàn)這樣聲音要重視起來(lái)！

　　Many people hear the abnormal sound of concrete mixer in the process of operation will not pay attention to it, which falls into a wrong area, often cause damage to mechanical equipment, so the sound of concrete mixer should pay attention to it!

　　混凝土攪拌機(jī)低速啟動(dòng)發(fā)動(dòng)機(jī)突然變速時(shí)，缸體上部會(huì)發(fā)出“咣咣咣咣”的聲音，這是由于之間的間隙過(guò)大造成的活塞銷(xiāo)和連桿襯套，或帶活塞銷(xiāo)座。

　　Concrete mixer suddenly start the engine at low speed with speed, on cylinder body ministries send out the voice of “MAO MAO MAO MAO”， this is due to the large clearance between the piston pin and connecting rod bushing, or take the piston pin.

　　混凝土攪拌機(jī)在開(kāi)始高速運(yùn)轉(zhuǎn)時(shí)，會(huì)發(fā)出“咔、咔”的悶響，尤其是在油門(mén)突然減小時(shí)尤為嚴(yán)重，這是由于油門(mén)軸向間隙過(guò)大造成的。

　　When the concrete mixer starts running at high speed, it will make a dull “crack, crack” sound, especially when the throttle suddenly decreases for a few hours, which is caused by the excessive axial clearance of the throttle.

　　當(dāng)聽(tīng)到氣缸全長(zhǎng)發(fā)出轟隆隆、沉悶的“空咚、空咚”敲擊聲時(shí)，打開(kāi)加油口蓋，發(fā)現(xiàn)有氣泡（表示有漏氣），這是活塞和氣缸。由于套筒間隙過(guò)大。

　　When hearing the full length of the cylinder issued a rumbling, dull “empty thunk, empty thunk” knock sound, open the refueling cover, found that there are bubbles （indicating a leak）， this is the piston and cylinder. Because the sleeve clearance is too large.

　　如果在曲軸方向的同一部位輕微聽(tīng)到“嘎、嘎、嘎”的撞擊聲，是工作時(shí)連桿扭動(dòng)引起的震動(dòng)聲。后兩種聲音在速度變化時(shí)更加明顯。聽(tīng)得見(jiàn)，很容易分辨；有類(lèi)似小錘子敲擊氣缸上下鐵塊的聲音，柴油機(jī)排氣管冒藍(lán)煙（伴有燒機(jī)油現(xiàn)象），用長(zhǎng)柄螺絲刀輕觸氣缸如果在本體處比較容易聽(tīng)到，可以判斷是活塞環(huán)側(cè)間隙過(guò)大或環(huán)斷裂。

　　If the same part of the crankshaft direction slightly hear the sound of “quack, quack, quack”， it is the vibration caused by the twist of the connecting rod when working. The latter two sounds are more pronounced when the speed changes. It is easy to distinguish; There is similar to the sound of a small hammer hitting the upper and lower iron blocks of the cylinder, the diesel engine exhaust pipe smoke blue （accompanied by burning oil phenomenon）， with a long handle screwdriver gently touch the cylinder if it is easy to hear in the body, you can judge that the piston ring side clearance is too large or ring fracture.

　　柴油機(jī)突然改變負(fù)荷時(shí)，在曲軸箱附近（從缸體中部到下部）可清晰聽(tīng)到急促的“空、空、空”沉悶的敲擊聲，且隨著負(fù)荷的增加或轉(zhuǎn)速和急劇變化，聲音增大，打開(kāi)加油口蓋可以聽(tīng)得更清楚，空載時(shí)不明顯。這是由于連桿襯套磨損過(guò)大，導(dǎo)致連桿襯套與曲軸連桿軸頸間隙過(guò)大。

　　Diesel engine suddenly change the load, near the crankcase （from the middle of the cylinder block to the bottom） can clearly hear the rapid “empty, empty, empty” dull knocking sound, and with the increase of load or speed and rapid change, the voice increases, open the refueling cover can hear more clearly, no load is not obvious. This is because the connecting rod bushing wear is too large, resulting in connecting rod bushing and crankshaft connecting rod journal clearance is too large.
