焦化发电机组的紧固件组装是非常重要的一个环节，如果开始没有装好，后续可能会非常多的问题。今天为大家介绍一下焦化发电机组紧固件组装的具体注意事项，希望对大家有帮助。

The fastener assembly of coking generator unit is a very important link. If it is not installed at the beginning, there may be many problems left in the future. Today, I would like to introduce the specific precautions for the assembly of fasteners of coking generator set, hoping to help you.

1.气缸盖螺母的组装

1. Assembly of cylinder head nuts

拧紧气缸盖螺母时，应分数次逐步拧紧到规定的力矩，并按先中间、后两边、对角交叉的原则进行。拆缸时也应按规定顺序逐步拧松。若气缸盖螺母拧紧得不均匀或不平衡，会引起缸盖平面翘曲变形。若螺母拧得过紧，螺栓会拉伸变形，机体和螺纹也会受到损坏。若螺母拧得不够紧，会造成气缸漏气、漏水、漏油，气缸内的高温气体也会烧坏气缸垫。

When tightening the cylinder head nuts, gradually tighten them to the specified torque several times, and proceed according to the principle of first middle, then two sides and diagonal crossing. When removing the cylinder, loosen it gradually according to the specified sequence. If the cylinder head nuts are tightened unevenly or unevenly, the cylinder head plane will be warped and deformed. If the nut is tightened too tightly, the bolt will be stretched and deformed, and the body and thread will also be damaged. If the nut is not tightened enough, it will cause air, water and oil leakage in the cylinder, and the high-temperature gas in the cylinder will also burn the cylinder gasket.

2.飞轮螺母的组装

2. Assembly of flywheel nut

安装时飞轮螺母须拧紧，并用止推垫圈折边锁紧。如果飞轮螺母拧得不紧，焦化机工作时，会产生敲击声，严重时会损坏曲轴锥面，剪裂键槽，扭断曲轴，造成严重事故。另外还要注意止推垫圈的角只能扳折一次。

During installation, the flywheel nut must be tightened and locked with thrust washer. If the flywheel nut is not tightened tightly, the coking machine will produce a knocking sound when it is working. In serious cases, it will damage the conical surface of the crankshaft, cut the keyway, and twist the crankshaft, causing serious accidents. Also note that the angle of the thrust washer can only be broken once.

3.连杆螺栓的组装

3. Assembly of connecting rod bolts

用友良钢材加工的连杆螺栓在工作中承受很大冲击力，不能用普通螺栓代替。拧紧时扭力要均匀，两根连杆螺栓要轮流分几次逐步拧紧到规定力矩，后用镀锌铁丝锁紧。

The connecting rod bolts made of Yosemite steel bear great impact force during work and cannot be replaced by ordinary bolts. When tightening, the torque should be uniform. The two connecting rod bolts should be tightened gradually to the specified torque several times in turn, and then locked with galvanized iron wire.

若连杆螺栓扭紧力矩过大，会使螺栓拉伸变形甚至折断，引起捣缸事故;若连杆螺栓拧紧力矩过小，轴瓦间隙增大，工作时产生敲击声和冲击载荷，甚至发生烧瓦抱轴及连杆螺栓折断事故。

If the tightening torque of the connecting rod bolt is too large, the bolt will be stretched and deformed or even broken, causing the cylinder tamping accident; If the tightening torque of the connecting rod bolt is too small, the clearance of the bearing bush will increase, resulting in knocking sound and impact load during operation, and even the accident of burning the bearing bush and holding the shaft and breaking the connecting rod bolt.

4.主轴承螺栓的组装

4. Assembly of main bearing bolts

应保证主轴承的安装精度，且不松动。拧紧主轴承螺栓时，5道主轴承应按照先中间，后2、4道，再1、5道的顺序，分2～3次均匀拧紧到规定的力矩。每拧紧一道还应检查一次曲轴转动是否正常。主轴承螺栓拧紧力矩过大或过小所产生的危害，与连杆螺栓拧紧力矩过大或过小所产生的危害基本相同。

The installation accuracy of the main bearing shall be guaranteed without looseness. When tightening the main bearing bolts, the five main bearings should be tightened evenly to the specified torque in 2-3 times in the sequence of first middle, then 2 and 4, then 1 and 5. Check whether the crankshaft rotates normally after each tightening. The harm caused by excessive or too small tightening torque of main bearing bolts is basically the same as that caused by excessive or too small tightening torque of connecting rod bolts.

5.平衡块螺栓的组装

5. Assembly of balance weight bolts

平衡块螺栓安装时应按顺序，分几次逐步拧紧到规定力矩。平衡块应按原位装复，否则会失去平衡作用。

When installing the balance weight bolts, tighten them gradually to the specified torque in sequence and several times. The balance weight shall be reinstalled in situ, otherwise it will lose its balance function.

6.摇臂座螺母的组装

6. Assembly of rocker arm seat nut

对于摇臂座螺母，在使用过程中要结合保养经常定期检查。如果摇臂座螺母松动，会使气门间隙增大，气门开启延后，关闭提前，气门开启延续时间缩短，引起焦化机供气不足，排气不净，功率下降，油耗增加。

The rocker arm seat nut should be regularly checked in combination with maintenance during use. If the rocker arm seat nut is loose, the valve clearance will increase, the valve opening will be delayed, the valve closing will be advanced, and the valve opening duration will be shortened, resulting in insufficient air supply, dirty exhaust, reduced power and increased fuel consumption of the coking machine.
