很多人听到混凝土搅拌机在运行过程中出现异常的声音不会很重视,这就陷入了一个错误的误区,往往会造成机械设备的损害,那么混凝土搅拌机出现这样声音要重视起来!
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!
混凝土搅拌机低速启动发动机突然变速时,缸体上部会发出“咣咣咣咣”的声音,这是由于之间的间隙过大造成的活塞销和连杆衬套,或带活塞销座。
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.
混凝土搅拌机在开始高速运转时,会发出“咔、咔”的闷响,尤其是在油门突然减小时尤为严重,这是由于油门轴向间隙过大造成的。
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.
当听到气缸全长发出轰隆隆、沉闷的“空咚、空咚”敲击声时,打开加油口盖,发现有气泡(表示有漏气),这是活塞和气缸。由于套筒间隙过大。
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.
如果在曲轴方向的同一部位轻微听到“嘎、嘎、嘎”的撞击声,是工作时连杆扭动引起的震动声。后两种声音在速度变化时更加明显。听得见,很容易分辨;有类似小锤子敲击气缸上下铁块的声音,柴油机排气管冒蓝烟(伴有烧机油现象),用长柄螺丝刀轻触气缸如果在本体处比较容易听到,可以判断是活塞环侧间隙过大或环断裂。
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.
柴油机突然改变负荷时,在曲轴箱附近(从缸体中部到下部)可清晰听到急促的“空、空、空”沉闷的敲击声,且随着负荷的增加或转速和急剧变化,声音增大,打开加油口盖可以听得更清楚,空载时不明显。这是由于连杆衬套磨损过大,导致连杆衬套与曲轴连杆轴颈间隙过大。
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.
