自动混凝土搅拌机是一种工作强度大、可靠性要求高的工程机械。为保证其高效的工作状态,日常维护尤为重要。但是长期使用后,发动机可能会损坏,那么在什么情况下应该对发动机进行大修呢?下面将为您详细介绍。
Automatic concrete mixer is a kind of engineering machinery with high working intensity and high reliability requirements. In order to ensure its efficient working state, daily maintenance is particularly important. But after long-term use, the engine may be damaged, so under what circumstances should the engine be overhauled? The following will give you a detailed introduction.
1、筒体内径磨损过大,圆度偏差0.04-0.06mm,圆柱度偏差0.08-0.12mm(一般测量筒体下半部与上半部之差)。对于多缸发动机,圆度和圆柱度偏差以磨损严重的气缸为准。
1. The inner diameter of the cylinder is excessively worn, with roundness deviation of 0.04-0.06mm and cylindricity deviation of 0.08-0.12mm (generally measure the difference between the lower half and the upper half of the cylinder). For multi cylinder engine, roundness and cylindricity deviation shall be subject to the cylinder with serious wear.
2、油量明显增加,油压下降,排气管冒黑蓝烟。
2. The oil volume increases significantly, the oil pressure decreases, and the exhaust pipe emits black and blue smoke.
3、混凝土运输搅拌机的功率显着降低。其大马力仅为额定功率的60%左右(不包括高海拔造成的功率下降),气缸压力低于标准压力的65%。
3. The power of concrete transportation mixer is significantly reduced. Its high horsepower is only about 60% of the rated power (excluding the power reduction caused by high altitude), and the cylinder pressure is 65% lower than the standard pressure.
4、曲轴磨损过大,曲轴各轴颈磨损后的圆度和圆柱度偏差超过使用极限,或不圆度和锥度限制在0.10mm以内。
4. The crankshaft is excessively worn, and the roundness and cylindricity deviation of each crankshaft journal after wear exceeds the service limit, or the out of roundness and taper are limited within 0.10mm.

5、发动机启动或停止时,水温在50^-60℃的条件下不能顺利启动。
5. When the engine starts or stops, the water temperature cannot start smoothly under the condition of 50 ^-60 ℃.
6、自动混凝土搅拌机的发动机有异响或运转异常。发动机在热态运转时,气缸内有响声(活塞敲击声),主轴承或连杆轴承有严重的振动或敲击声。
6. The engine of the automatic concrete mixer has abnormal noise or abnormal operation. When the engine is running in hot state, there is a noise (piston knocking) in the cylinder, and the main bearing or connecting rod bearing has serious vibration or knocking.
以上是混凝土运输搅拌车发动机检修的条件,此外,在有可能结冰的环境中使用时,必须将供水系统排空并储存,以防止管道结冰和开裂;经常检查系统的密封性,对关键部位的管道进行密封。更多内容就来我们网站http://www.zkhntjbc.com获取信息吧。
The above conditions are for the maintenance of the engine of the concrete transportation mixer. In addition, when it is used in an environment that may be frozen, the water supply system must be emptied and stored to prevent the pipeline from freezing and cracking; Regularly check the tightness of the system and seal the pipes at key parts.
