Why does the biogas generator set vibrate? Now let the technicians of biogas generator set explain to you, hoping to help you.
活塞销折断活塞销强度不够或有裂纹,活塞销与活塞、连杆衬套的间隙过大,产生较大的冲击力;活塞销孔的线偏斜,与活塞的线不垂直,漏装活塞销卡环或卡环环槽磨损活塞销窜出等,都会造成活塞销折断。
The broken piston pin has insufficient strength or cracks, and the clearance between the piston pin and the piston and connecting rod bushing is too large, resulting in large impact force; The center line of the piston pin hole is skewed, not perpendicular to the center line of the piston, the piston pin snap ring is not installed, or the piston pin moves out due to the wear of the snap ring groove, which will cause the piston pin to break.
连杆劈断、折断由于飞车,使连杆负荷超载或连杆弯曲、扭曲,有砂眼等而造成连杆劈断或折断。
The connecting rod is split or broken due to the overload of the connecting rod or the bending, twisting and sand holes of the connecting rod caused by the flying car.
连杆螺栓折断连杆螺栓的扭力矩过大,螺栓拉伸变形;扭力矩过小,轴瓦间隙变大,产生冲击载荷;连杆螺栓材质不好或倒扣、滑扣、承载能力差等而导致连杆螺栓折断。
The connecting rod bolt is broken, the torque of the connecting rod bolt is too large, and the bolt is stretched and deformed; When the torque is too small, the bearing bush clearance becomes larger, resulting in impact load; The connecting rod bolt is broken due to the poor material of the connecting rod bolt or the poor back-off, sliding and bearing capacity.
气门掉入气缸气门杆折断;气门锁瓣脱落,卡簧失去作用;气门弹簧折断等使气门掉入气缸。
The valve falls into the cylinder and the valve rod is broken; The valve key falls off and the circlip loses its function; Broken valve spring, etc. causes the valve to fall into the cylinder.

缸套台肩处折断缸套台肩与缸体贴合处圆角太小或没有圆角,在发动机交变载荷作用下,该处应力集中而折断;因阻水圈不适合,安装缸套时需用力敲打,用力又不均,使缸套强度薄弱处产生裂纹;由于各种原因,缸套安装后倾斜,在活塞侧压力作用下,缸套纵向产生轻微摆动,时间久后缸套折断。
Broken at the shoulder of the cylinder liner The fillet at the joint of the shoulder of the cylinder liner and the cylinder block is too small or there is no fillet. Under the action of the alternating load of the engine, the stress at this place is concentrated and broken; Because the water stop ring is not suitable, the cylinder liner needs to be knocked hard when installing, and the force is uneven, which causes cracks at the weak part of the cylinder liner; Due to various reasons, the cylinder liner inclines after installation. Under the pressure of the piston side, the cylinder liner swings slightly in the longitudinal direction, and the cylinder liner breaks after a long time.
活塞销孔断裂活塞与缸套间隙过小,粘缸后拉断活塞;活塞与缸套间隙过大,活塞在缸套内摆动而被打坏;连杆弯曲、扭曲,使活塞受较大的附加应力;活塞与活塞销紧度过大或装配方式不当,使活塞变形或产生裂纹;活塞材质不好等造成活塞销孔断裂。
The piston pin hole is broken, and the clearance between the piston and the cylinder liner is too small, and the piston is pulled out after sticking to the cylinder; The clearance between the piston and the cylinder liner is too large, and the piston swings in the cylinder liner and is damaged; The connecting rod is bent and twisted, which makes the piston subject to greater additional stress; The piston and piston pin are too tight or the assembly method is improper, resulting in piston deformation or cracks; The piston pin hole is broken due to poor piston material.
操作不当熄火、起动或作业中,常猛轰油门,使转速骤增、骤减频繁,有关零件受到比正常工作时大好几倍的冲击载荷而疲劳损坏产生捣缸。
When the engine is shut down, started or operated improperly, the accelerator is often slammed, resulting in the sudden increase and decrease of the speed, and the fatigue damage of the relevant parts caused by the impact load several times greater than that of the normal operation.
凸轮轴折断、飞车及某缸烧瓦后整机强行起动作业等,也易引起捣缸事故。更多相关发电机组的事项就来我们网站http://www.huannengpower.com看看!
Broken camshafts, flying cars and forced starting of the whole machine after a certain cylinder is burnt are also easy to cause cylinder vibration accidents. For more matters related to generator set, please visit our website http://www.huannengpower.com have a look!
