沼氣發(fā)電機組為什么會出現(xiàn)搗缸現(xiàn)象呢？現(xiàn)在就讓沼氣發(fā)電機組的技術人員為大家講解，希望可以幫助到大家。

Why does the biogas generator set vibrate? Now let the technicians of biogas generator set explain to you, hoping to help you.

活塞銷折斷活塞銷強度不夠或有裂紋，活塞銷與活塞、連桿襯套的間隙過大，產(chǎn)生較大的沖擊力；活塞銷孔的線偏斜，與活塞的線不垂直，漏裝活塞銷卡環(huán)或卡環(huán)環(huán)槽磨損活塞銷竄出等，都會造成活塞銷折斷。

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.

連桿劈斷、折斷由于飛車，使連桿負荷超載或連桿彎曲、扭曲，有砂眼等而造成連桿劈斷或折斷。

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.

連桿螺栓折斷連桿螺栓的扭力矩過大，螺栓拉伸變形；扭力矩過小，軸瓦間隙變大，產(chǎn)生沖擊載荷；連桿螺栓材質(zhì)不好或倒扣、滑扣、承載能力差等而導致連桿螺栓折斷。

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.

氣門掉入氣缸氣門桿折斷；氣門鎖瓣脫落，卡簧失去作用；氣門彈簧折斷等使氣門掉入氣缸。

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.

缸套臺肩處折斷缸套臺肩與缸體貼合處圓角太小或沒有圓角，在發(fā)動機交變載荷作用下，該處應力集中而折斷；因阻水圈不適合，安裝缸套時需用力敲打，用力又不均，使缸套強度薄弱處產(chǎn)生裂紋；由于各種原因，缸套安裝后傾斜，在活塞側壓力作用下，缸套縱向產(chǎn)生輕微擺動，時間久后缸套折斷。

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.

活塞銷孔斷裂活塞與缸套間隙過小，粘缸后拉斷活塞；活塞與缸套間隙過大，活塞在缸套內(nèi)擺動而被打壞；連桿彎曲、扭曲，使活塞受較大的附加應力；活塞與活塞銷緊度過大或裝配方式不當，使活塞變形或產(chǎn)生裂紋；活塞材質(zhì)不好等造成活塞銷孔斷裂。

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.

操作不當熄火、起動或作業(yè)中，常猛轟油門，使轉速驟增、驟減頻繁，有關零件受到比正常工作時大好幾倍的沖擊載荷而疲勞損壞產(chǎn)生搗缸。

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.

凸輪軸折斷、飛車及某缸燒瓦后整機強行起動作業(yè)等，也易引起搗缸事故。更多相關發(fā)電機組的事項就來我們網(wǎng)站http://m.pyucoin.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://m.pyucoin.com have a look!
