一说到“拉缸”二字，很多车主就面露难色，发动机拉缸是指气缸内壁在活塞环的运动范围内出现明显的纵向机械划痕和刮伤，严重时发生熔着性磨损，造成发动机启动困难或者自行熄火的故障。那么是哪些因素导致发动机拉缸症状？而面对拉缸症状我们该怎么样保养呢？全自动搅拌车厂家为您解说。
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.
发动机出现拉缸的原因
Causes of engine cylinder scuffing
1、发动机冷却系统因为泄漏、缺水，不能及时补充导致发动机过热;
1. The engine cooling system can not be replenished in time due to leakage and water shortage, resulting in engine overheating;
2、全自动搅拌车发动机机油太低，导致气缸密封性、润滑功能丧失;
2. The engine oil of the automatic mixer is too low, resulting in the loss of cylinder sealing and lubrication functions;
3、活塞环断裂，刮伤缸壁;
3. The piston ring breaks and scratches the cylinder wall;
4、活塞销卡圈脱落，刮伤缸壁;
4. The piston pin circlip falls off and scratches the cylinder wall;
5、活塞环因为积炭卡死在槽内，密封作用丧失;
5. The piston ring is stuck in the groove due to carbon deposit, and the sealing effect is lost;
6、活塞销外出，刮伤缸壁;
6. The piston pin goes out and scratches the cylinder wall;
7、气缸内进入异物;
7. Foreign matters enter the cylinder;
8、活塞和缸壁配合间隙过小;
8. The fit clearance between piston and cylinder wall is too small;
9、活塞销装配过紧，导致变形;
9. Piston pin assembly is too tight, resulting in deformation;
10、活塞热变形严重或烧顶熔化;
10. The piston is severely deformed or the top is melted;
11、全自动搅拌车发动机长时间高速或超负荷运转。
11. The engine of the fully automatic mixer operates at high speed or overload for a long time.
怎么预防发动机拉缸?
How to prevent engine from scuffing?
1、新机和大修后的发动机，需要磨合;
1. New engine and overhauled engine need to be run in;
2、维修发动机要确保;
2. Ensure safety during engine maintenance;
3、行驶时注意观察发动机水温。水温正常的温度是70℃～95℃，避免发动机过热。现在天气变冷，建议大家开车前预热。
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、合理使用全自动搅拌车发动机，不要超负荷作业
4. Reasonably use the engine of the fully automatic mixer truck, and do not overload operation
5、定期更换空气滤清器
5. Replace the air filter regularly
6、保证润滑系统正常工作
6. Ensure normal operation of the lubrication system
7、及时检查发动机机油油面高度，保证不缺机油。
7. Check the engine oil level in time to ensure that there is no shortage of oil.
