The diesel generator set accessories cylinder liner, piston and cylinder head together form the combustion chamber, so if there is a problem during installation, it will inevitably affect the operation of the unit, and there will be undesirable phenomena such as insufficient combustion, then install the diesel generator set accessories cylinder liner What do you need to pay attention to? Today I will share with you the skills in this regard.
1. Do not forget to install the cylinder liner gasket before the cylinder liner is in place, and carefully check the cleanliness of each part.
2. The pressing force of the cylinder liner should not be too large, especially when the upper shoulder of the cylinder liner is in contact with the plane of the upper seat hole of the body, the pressure cannot be continued, and the cylinder head can be used, but the old cylinder head gasket must be placed in the middle. In order to prevent the cylinder head from pressing the inner port of the cylinder liner, the lower plane of the shoulder contacts the upper plane of the upper seat hole of the body, forming a pair of force couples, which is enough to cause the cylinder liner to break from the weak part of the lower part of the shoulder; The head bolts are made of sleeves with feet according to half the number of cylinder head bolts. The length of the feet is just pressed against the cylinder head gasket of the cylinder set, and cannot be long. The sleeves are spaced and symmetrically sleeved on the cylinder head bolts. The nuts are compressed alternately and symmetrically, and the cylinder liner can be in place.
3. Before the cylinder liner is placed, check the positioning line or mark between the cylinder liner and the body, and the cylinder liner gasket is in the correct position.
4. Install the water seal ring, check that the water seal ring is intact, and the dimensions meet the above standards. When installing the water seal ring, lift it by hand for one to two laps before placing it in place, and check that the water seal ring cannot be twisted or rolled. , The tightness of the circumference should be uniform, the interface of the abrasive tool should be in the upper and lower parts, and then the lifting part should fall into the groove, and then check it should be correct.
5. Before the cylinder sleeve is installed into the body, the water seal ring should be coated with alkaline soap or neutral lubricant, which will lubricate the water seal ring and the lower seat hole of the body when the cylinder is installed, so as to prevent the water seal from being damaged and rolling. , dislocation and other abnormal phenomena.
