How to solve the problem of noise produced by piston cylinder of automatic feeding mixer?

　　自动上料搅拌机在驱动过程中会产生活塞环的异常声音。下面将描述判断和处理自动上料搅拌机的方法。

　　In the process of driving, the automatic feeding mixer will produce the abnormal sound of life plug ring. The method of judging and handling the automatic feeding mixer will be described below.

　　活塞起爆缸的主要原因如下：活塞与缸壁之间的间隙太大。WD615系列发动机的活塞裙和气缸的标准间隙为0.143-0.182，磨损极限为0.35-0.40。发动机运转一段时间后，气缸活塞磨损并且润滑不良。活塞和气缸之间的匹配间隙由于磨损而增大，并且在气环中发生了严重的台阶，从而导致活塞撞击气缸。声音异常。经过一段时间的操作后，活塞裙和缸体严重磨损，导致严重的倒圆并冲击缸体。每个链节由于各种原因而变形，导致活塞偏心，间隙变大，汽缸被撞击。活塞爆震缸将导致过多的发动机燃油消耗，发动机燃油消耗，燃油消耗和经济性。当活塞严重撞击气缸时，它将拉动活塞并使气缸破裂，从而导致连杆断裂并损坏气缸体。
          

　　The main reasons for the piston bursting are as follows: the gap between the piston and the cylinder wall is too large. The standard clearance between piston skirt and cylinder of WD615 Series engine is 0.143-0.182, and the maximum wear limit is 0.35-0.40. After the engine has been running for some time, the cylinder piston is worn and poorly lubricated. The matching clearance between the piston and the cylinder increases due to wear, and serious steps occur in the first gas ring, resulting in the piston hitting the cylinder. Abnormal sound. After a period of operation, the piston skirt and cylinder block are severely worn, resulting in serious rounding and impact on the cylinder block. Each chain link is deformed due to various reasons, resulting in eccentric piston, larger clearance and cylinder being hit. Piston knock cylinder will lead to excessive engine fuel consumption, engine fuel consumption, fuel consumption and economy. When the piston hits the cylinder severely, it will pull the piston and break the cylinder, which will cause the connecting rod to break and damage the cylinder block.

　　判断活塞爆裂的方法：

　　To judge the bursting of piston:

　　（1）气缸到气缸的切削：爆破气缸的位置是通过逐气缸方法确定的。如果将机油切入气缸，声音会大大降低或消失，并且在恢复供油时，可以清晰听到。嗒嗒“声音，表明气缸活塞撞击气缸。

　　（1） Cylinder to cylinder cutting: the position of the blasting cylinder is determined by cylinder by cylinder method. If the oil is cut into the cylinder, the sound will be greatly reduced or disappear, and can be heard clearly when the oil supply is restored. The "click" sound indicates that the cylinder piston strikes the cylinder.

　　（2）为了进一步确认气缸活塞已被敲击，可以将气缸的喷油器取下，向气缸中添加少量的CD级增压油（密封件），安装喷油器，然后发动机开始。敲击声消失或减弱。手术后，会再次出现敲门声，无疑会敲打气缸的气缸。

　　（2） In order to further confirm that the cylinder piston has been knocked, the fuel injector of the cylinder can be removed, a small amount of Cd level booster oil （seal） can be added to the cylinder, the fuel injector can be installed, and then the engine starts. The knocking sound disappears or weakens. After the operation, there will be a knock on the door again, which will undoubtedly knock on the cylinder of the cylinder.

　　对于活塞缸，可以使用以下方法：

　　For piston cylinders, the following methods can be used:

　　（1）发动机启动后，在低温下运转时，发动机会发出爆震声。温度恢复正常后，声音消失，无需进一步处理即可暂时处理。

　　（1） When the engine is started and running at low temperature, the engine will knock. After the temperature returns to normal, the sound disappears and can be temporarily processed without further processing.

　　（2）当发动机温度正常时，会发出清晰的爆震声。尽量避免高速操作，拆卸和维修。

　　（2） When the engine temperature is normal, there will be a clear knocking sound. Try to avoid high-speed operation, disassembly and maintenance.

　　（3）拆下气缸盖并拔出活塞后，发现气缸严重脱离或变形，或活塞与气缸之间的间隙过大，应更换气缸套，活塞和活塞环。

　　（3） After the cylinder head is removed and the piston is pulled out, it is found that the cylinder is seriously separated or deformed, or the clearance between the piston and the cylinder is too large, the cylinder sleeve, piston and piston ring should be replaced.

　　（4）如果发现连杆（混凝土搅拌机）变形，则应尽可能更换。

　　（4） If the connecting rod （concrete mixer） is found to be deformed, it should be replaced as much as possible.
