柴油发电机组阀门泄漏的危害是什么?

来源:https://www.huannengpower.cn/ 文章作者:济柴环能 发布时间:2022-08-06
柴油发电机组的气门是机组中的重要零件,直接影响机组的密封及相关性能,而且其工作环境较为恶劣,会受到强烈的机械负荷以及高温、化学腐蚀等作用,须正确安装,气门在开箱和运输过程中,不得磕碰,在使用过程中,不得超负荷及承受额外的附加力,否则将使气门变形失效,导致早期损坏。接下来,将为大家介绍柴油发电机组气门漏气的危害。
The valve of the diesel generator set is an important part of the unit, which directly affects the sealing and related performance of the unit. Moreover, its working environment is relatively bad, and it will be subjected to strong mechanical load, high temperature, chemical corrosion and other effects. It must be installed correctly. The valve shall not be bumped during unpacking and transportation. During use, it shall not be overloaded and bear additional force, otherwise, the valve will be deformed and invalid, resulting in early damage. Next, I will introduce the hazards of valve leakage of diesel generator set.
柴油发电机组气门漏气会直接影响发动机的工作特性和使用的经济性。因此,维修及使用人员对机组的气门漏气要引起高度的重视。
The valve leakage of diesel generator set will directly affect the working characteristics and economic efficiency of the engine. Therefore, the maintenance and user should pay great attention to the valve leakage of the unit.
柴油发电机组气门漏气会造成发动机气缸漏气、油耗增加、燃料在气缸燃烧不良、排气冒烟或空气滤清器窜气,严重时会使发动机起动困难,甚至使发动机工作平衡受破坏,运动过程常出现异常振动。
The valve leakage of the diesel generator set will cause air leakage of the engine cylinder, increase fuel consumption, poor combustion of fuel in the cylinder, exhaust smoke or air filter blow by. In serious cases, it will make it difficult to start the engine, and even damage the working balance of the engine. Abnormal vibration often occurs in the movement process.
柴油发电机组气门漏气在高温气流的冲烧下,气门头部和气门座很快被烧蚀,使机械强度下降,进而磨损、变形,使漏气更加严重和积炭增多,造成恶性循环。
Under the impact of the high-temperature air flow, the valve head and valve seat of the diesel generator set will be quickly ablated, which will reduce the mechanical strength, and then wear and deform, making the leakage more serious and the carbon deposition more, resulting in a vicious cycle.
如果是排气门漏气,又遇上排气管积炭堵塞排气不畅、气门导杆和导管间隙过大时,会有一部分高温废气沿着气门导杆和气门导管的间隙冲刷润滑油后进入气门室,污染气门室,使气门室摇臂部件润滑不良,温度升高,粘附积炭,加速柴油发电机组配气机构的磨损和损坏。
If the exhaust valve leaks, and the exhaust pipe is blocked by carbon deposition, the exhaust is not smooth, and the clearance between the valve guide rod and the guide tube is too large, some high-temperature exhaust gas will wash the lubricating oil along the clearance between the valve guide rod and the valve guide tube and enter the valve chamber, polluting the valve chamber, causing poor lubrication of the rocker arm parts of the valve chamber, increasing the temperature, adhering to carbon deposition, and accelerating the wear and damage of the valve mechanism of the diesel generator set.
如果是进气门漏气,漏气的气缸在压缩过程中,压缩温度不能使正时喷入的油自然发火,而部分可燃混合气通过进气门漏气缝隙处回流吸气口、进气管,随后又在下一循环的进气行程重新吸入气缸,当工作行程气缸内又喷入常量燃油时,这些聚积的燃油和可燃混合气会发生燃烧,使发动机工作粗暴,发出敲击声。
In case of air leakage from the intake valve, the compression temperature of the cylinder with air leakage cannot cause the oil injected at the timing to ignite naturally during the compression process, while part of the combustible mixture flows back to the intake port and intake pipe through the air leakage gap of the intake valve, and then is re sucked into the cylinder during the intake stroke of the next cycle. When constant fuel is injected into the cylinder during the working stroke, these accumulated fuel and combustible mixture will burn, causing the engine to work rough, Knock.
若是多缸发动机,当某,个缸的进气门漏气后,倒流入进气管的可燃混合气或废气将被吸入其他缸,使其他缸的工作也受到影响。
In the case of a multi cylinder engine, when the intake valve of a certain cylinder leaks, the fuel mixture or exhaust gas flowing back into the intake pipe will be sucked into other cylinders, and the work of other cylinders will also be affected.
柴油发电机组气门出现漏气故障后,如不及时的对柴油发电机组维修重新研磨气门,恢复其密封性,在短时间内将发展为气门座、气门头锥面、气门杆根部的烧蚀,导致不能修复需要更换新件和存在气门折断掉入气缸内的危险以及机件损坏的隐患。
In case of air leakage of the diesel generator set valve, if the diesel generator set is not repaired and reground in time to restore its sealing property, it will develop into the ablation of the valve seat, valve head cone and valve stem root in a short time, resulting in the failure to repair and replacement of new parts, the risk that the valve will break and fall into the cylinder, and the hidden danger of mechanical damage.
