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

　　自動上料攪拌機在驅動過程中會產生活塞環的異常聲音。下面將描述判斷和處理自動上料攪拌機的方法。

　　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：活塞與缸壁之間的間隙太大。WD615系列發動機的活塞裙和氣缸的標準間隙為0.143-0.182，磨損極限為0.35-0.40。發動機運轉一段時間后，氣缸活塞磨損并且潤滑不良。活塞和氣缸之間的匹配間隙由于磨損而增大，并且在氣環中發生了嚴重的臺階，從而導致活塞撞擊氣缸。聲音異常。經過一段時間的操作后，活塞裙和缸體嚴重磨損，導致嚴重的倒圓并沖擊缸體。每個鏈節由于各種原因而變形，導致活塞偏心，間隙變大，汽缸被撞擊。活塞爆震缸將導致過多的發動機燃油消耗，發動機燃油消耗，燃油消耗和經濟性。當活塞嚴重撞擊氣缸時，它將拉動活塞并使氣缸破裂，從而導致連桿斷裂并損壞氣缸體。
          

　　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.

　　判斷活塞爆裂的方法：

　　To judge the bursting of piston:

　?。?）氣缸到氣缸的切削：爆破氣缸的位置是通過逐氣缸方法確定的。如果將機油切入氣缸，聲音會大大降低或消失，并且在恢復供油時，可以清晰聽到。嗒嗒“聲音，表明氣缸活塞撞擊氣缸。

　?。?） 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.

　?。?）為了進一步確認氣缸活塞已被敲擊，可以將氣缸的噴油器取下，向氣缸中添加少量的CD級增壓油（密封件），安裝噴油器，然后發動機開始。敲擊聲消失或減弱。手術后，會再次出現敲門聲，無疑會敲打氣缸的氣缸。

　?。?） 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.

　　對于活塞缸，可以使用以下方法：

　　For piston cylinders, the following methods can be used:

　?。?）發動機啟動后，在低溫下運轉時，發動機會發出爆震聲。溫度恢復正常后，聲音消失，無需進一步處理即可暫時處理。

　?。?） 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.

　?。?）當發動機溫度正常時，會發出清晰的爆震聲。盡量避免高速操作，拆卸和維修。

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

　　（3）拆下氣缸蓋并拔出活塞后，發現氣缸嚴重脫離或變形，或活塞與氣缸之間的間隙過大，應更換氣缸套，活塞和活塞環。

　?。?） 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.

　?。?）如果發現連桿（混凝土攪拌機）變形，則應盡可能更換。

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