Butter the cylinder mat. Butter is commonly used in engineering machinery repair grease, can play a role in lubrication and sealing.
Therefore, when installing the gasket, some repairmen butter the gasket, thinking that it will increase the tightness of the diesel engine. However, this has affected the performance of the diesel engine.
Cylinder pad is an important seal between the cylinder block and the cylinder head, it can not only seal the high temperature and high pressure gas produced in the cylinder, but also can seal the cooling water and lubricating oil in the cylinder head and cylinder body, so when disassembling the cylinder pad, we should pay special attention to its sealing quality.
If installed in the cylinder MATS and butter, when the cylinder head bolt is tightened, part of the butter will be squeezed into the cylinder in the channel and the oil duct, stay in the cylinder gasket between the butter in cylinder work, due to the effect of high temperature, part will shed cylinder combustion, others remain in the combination of the cylinder block and cylinder head, cylinder pad, cylinder head and the body plane between aperture, high temperature and high pressure gas from impact cylinder pad, easily damaged cylinder pad, cause air leakage.
In addition, the butter at high temperature for a long time will also produce carbon deposit, resulting in premature aging cylinder pad deterioration. Do not apply butter to the cylinder gasket.
Therefore, proper buttering can effectively improve the working performance and efficiency of SINOTENG construction machines.
