The repair method of cracks on the cylinder block and cylinder head of Weichai diesel generator set shall be determined according to the extent of the cracks, damage location, working condition of Weichai diesel generator set and equipment condition. The common repair methods include epoxy resin bonding, screw filling, patch filling, welding filling, leak stoppage, etc. The epoxy resin bonding of Weichai diesel generator set has the advantages of strong bonding force, small shrinkage, fatigue resistance, etc. At the same time, the process is simple, easy to operate, and low cost. The main disadvantage of Weichai diesel generator set is that it is not resistant to high temperature, impact, etc. When the Weichai diesel generator set is next repaired, it will fall off after boiling with hot alkaline water, and needs to be re bonded.
In addition to the high-temperature areas such as combustion chamber and valve seat of Weichai diesel generator set, the cylinder block and cylinder head of Weichai diesel generator set can be repaired by this method. The spiral filling method is applicable to the plane parts with small stress, small strength requirements and short crack range. Its maintenance quality is higher, but it requires more time. If a limit hole is drilled at each end of the crack of Weichai diesel generator set, to prevent the crack from continuing to expand. If Weichai diesel generator sets crack drill holes 3, 4 and 5, the diameter of the hole depends on the diameter of the thread, and ensure that the hole is 1/3 overlapped with the hole.
If the thread of Weichai diesel generator set is tapped out from the above holes 1, 2, 3, 4 and 5, screw the thread into the pre reamed copper rod (screw in some paint to white paint), and then cut off the copper rod to make the cutting point of Weichai diesel generator set 1-1.5mm higher than the crack surface. Drill 6, 7, 8 and 9 holes between the cutting screws, tap and screw in the screws according to the above method, so that the Weichai diesel generator set is full of cracks and forms a spiral chain. In order to fill tightly, use a hammer of Weichai diesel generator set to gently tap between the cutting screws, and finally use a file to repair (if necessary) soldering to prevent leakage of Weichai diesel generator set.
