一般情况下，在驾驶小型搅拌机的过程中是很少出现异常响声的，一旦出现异响那么有可能是您的小型搅拌机出现了故障问题，一些有经验的驾驶员从声音的状况便可以判断出小型搅拌机的故障问题来源。

In general, abnormal noise rarely occurs when driving a small mixer. Once abnormal noise occurs, it may be that your small mixer has a problem. Some experienced drivers can determine the source of the problem from the sound.

当柴油机忽然改动负荷时，在曲轴箱左近可明显地听到急促的“空、空、空”钝哑的敲击声，并随着小型搅拌机负荷或转速的增加而急剧变化，响声增大，翻开加油机盖可听得更分明，无负荷时则不明显。这是由于连杆瓦过度磨损而形成连杆瓦与曲轴连杆轴颈配合间隙过大所致，若使柴油机某缸断油，异响立刻消失，则证明是该缸的连杆瓦响。

When the load of the diesel engine is suddenly changed, a sharp "empty, empty, empty" dull knocking sound can be obviously heard near the left side of the crankcase, and it changes sharply with the increase of the load or speed of the small mixer. The noise increases. It can be heard more clearly when the fuel filler cover is opened, but it is not obvious when there is no load. This is due to the excessive wear of the connecting rod bush and the excessive fit clearance between the connecting rod bush and the crankshaft connecting rod journal. If a cylinder of the diesel engine is cut off and the abnormal noise disappears immediately, it is proved that the connecting rod bush of the cylinder is making noise.

如果在小型搅拌机发动机高速运转时，发出“咯噔、咯噔”的闷击声，忽然减小油门尤为严重，这是因主轴瓦轴向间隙过大所致。

If the engine of the small mixer runs at a high speed, it makes a clunking sound of "clunking, clunking", and suddenly reduces the accelerator, which is especially serious, because the axial clearance of the main bearing pad is too large.

当小型搅拌机的柴油机在其曲轴箱下部有繁重而连续的敲击声，低速时声音清晰可辨，重负荷时更加明显，同时油压随着降低，这是曲轴主轴瓦间隙过大造成的，当发动机低速忽然改动转速时，在气缸上部发出“铛、铛”的响声，这一般是活塞销与连杆衬套、或与活塞销座的配合间隙过大所致。

When the diesel engine of the small mixer has heavy and continuous knocking sound at the lower part of the crankcase, the sound is clear and recognizable at low speed, and more obvious at heavy load. At the same time, the oil pressure decreases with the increase of the clearance between the main bearing pads of the crankshaft. When the engine suddenly changes the speed at low speed, the sound of "clang, clang" is emitted at the upper part of the cylinder, which is generally caused by the excessive fit clearance between the piston pin and the connecting rod bushing, or between the piston pin seat.

如果在小型搅拌机发动机高速运转时，发出“咯噔、咯噔”的闷击声，忽然减小油门尤为严重，这是因主轴瓦轴向间隙过大所致，在气缸全长部位听到轰鸣、沉闷的“空咚、空咚”的敲击声，且翻开加油机口盖时发现有气泡，这是活塞与缸套配合间隙过大所致。

If the engine of a small mixer runs at high speed, it makes a clunking sound of "clunking, clunking" and suddenly reduces the accelerator, which is especially serious. This is because the axial clearance of the main bearing pad is too large. A loud, dull "hollow, hollow" knock is heard at the full length of the cylinder, and bubbles are found when opening the filler cap, which is caused by the excessive fitting clearance between the piston and the cylinder liner.

如果在小型搅拌机同一部位略靠曲轴方向听到“嘎、嘎、嘎”的撞击声，则是连杆扭曲致使其在工作中摇晃的敲击声，后两种声响在改动转速时更能明显听到，且较易于区别，沿气缸上下各处均有相似小铁锤轻击铁块的声音，柴油机排气管冒蓝烟（伴有烧机油现象），用长柄螺丝刀抵在缸体处更易于听出，这种情况就是活塞环侧隙过大或环折断所致。

If the impact sound of "quack, quack, quack" is heard at the same part of the small mixer slightly in the direction of the crankshaft, it is the knock sound caused by the twisting of the connecting rod during operation. The last two sounds can be heard more clearly when the speed is changed, and they are easier to distinguish. There are similar sounds of small hammers hitting iron blocks at the top and bottom of the cylinder, and the exhaust pipe of the diesel engine emits blue smoke (accompanied by oil burning), It is easier to hear when the long handle screwdriver is pressed against the cylinder block, which is caused by excessive side clearance of the piston ring or broken ring.
