一說到“拉缸”二字，很多車主就麵露難色，發動機拉缸是指氣缸內壁在活塞環的運動範圍內出現明顯的縱向機械劃痕和刮傷，嚴重時發生熔著性磨損，造成發動機啟動困難或者自行熄火的故障。那麽是哪些因素導致發動機拉缸症狀？而麵對拉缸症狀kaiyun該怎麽樣保養呢？全自動攪拌車廠家為您解說。
When it comes to the word "scuffing", many car owners are embarrassed. Engine scuffing refers to the failure that the inner wall of the cylinder has obvious longitudinal mechanical scratches and scratches within the range of motion of the piston ring, and in serious cases, it causes melting wear, which makes it difficult for the engine to start or automatically shut down. So what are the factors that cause the engine cylinder pulling symptom? And how should we maintain it in the face of cylinder pulling symptoms? The manufacturer of the automatic mixer will explain it to you.
發動機出現拉缸的原因
Causes of engine cylinder scuffing
1、發動機冷卻係統因為泄漏、缺水，不能及時補充導致發動機過熱;
1. The engine cooling system can not be replenished in time due to leakage and water shortage, resulting in engine overheating;
2、全自動攪拌車發動機機油太低，導致氣缸密封性、潤滑功能喪失;
2. The engine oil of the automatic mixer is too low, resulting in the loss of cylinder sealing and lubrication functions;
3、活塞環斷裂，刮傷缸壁;
3. The piston ring breaks and scratches the cylinder wall;
4、活塞銷卡圈脫落，刮傷缸壁;
4. The piston pin circlip falls off and scratches the cylinder wall;
5、活塞環因為積炭卡死在槽內，密封作用喪失;
5. The piston ring is stuck in the groove due to carbon deposit, and the sealing effect is lost;
6、活塞銷外出，刮傷缸壁;
6. The piston pin goes out and scratches the cylinder wall;
7、氣缸內進入異物;
7. Foreign matters enter the cylinder;
8、活塞和缸壁配合間隙過小;
8. The fit clearance between piston and cylinder wall is too small;
9、活塞銷裝配過緊，導致變形;
9. Piston pin assembly is too tight, resulting in deformation;
10、活塞熱變形嚴重或燒頂熔化;
10. The piston is severely deformed or the top is melted;
11、全自動攪拌車發動機長時間高速或超負荷運轉。
11. The engine of the fully automatic mixer operates at high speed or overload for a long time.
怎麽預防發動機拉缸?
How to prevent engine from scuffing?
1、新機和大修後的發動機，需要磨合;
1. New engine and overhauled engine need to be run in;
2、維修發動機要確保安全;
2. Ensure safety during engine maintenance;
3、行駛時注意觀察發動機水溫。水溫正常的溫度是70℃～95℃，避免發動機過熱。現在天氣變冷，建議大家開車前預熱。
3. Observe the engine water temperature when driving. The normal temperature of water temperature is 70 ℃~95 ℃ to avoid overheating of the engine. The weather is getting cold now. It is recommended that you warm up before driving.
4、合理使用全自動攪拌車發動機，不要超負荷作業
4. Reasonably use the engine of the fully automatic mixer truck, and do not overload operation
5、定期更換空氣濾清器
5. Replace the air filter regularly
6、保證潤滑係統正常工作
6. Ensure normal operation of the lubrication system
7、及時檢查發動機機油油麵高度，保證不缺機油。
7. Check the engine oil level in time to ensure that there is no shortage of oil.
