Background
The engine cylinder cover, the cylinder sleeve and the piston jointly form a combustion chamber of the diesel engine, and the combustion chamber is one of parts of the diesel engine which can bear high-temperature and high-pressure working conditions. The pretightening force of the bolts borne by the top surface of the cylinder cover is far greater than the combustion pressure, and the bottom surface of the cylinder cover bears the pressure and the heat load of high-pressure gas generated by fuel combustion. When the diesel engine works, the mechanical stress and the thermal stress born by the cylinder cover are very complicated. The inner cavity of the cylinder cover is provided with an air inlet channel, an exhaust channel, an air inlet valve, an exhaust valve, a fuel injector and the like. The cylinder head bottom plate, the air inlet valve, the air outlet valve, the exhaust passage, the oil injector and the like are in direct contact with high-temperature gas generated by combustion of fuel in the combustion chamber, and bear and transfer a part of heat of the high-temperature gas; in addition, mechanical and thermal stresses make the head plate susceptible to fatigue deformation. The cylinder cover is provided with a cooling water cavity, heated parts are cooled by cooling water, the heat load of the parts is improved, and the reliable use of the parts is ensured. The poor assembling state between the oil sprayer sleeve and the cylinder cover can cause cooling water to permeate or directly leak to a combustion chamber. If the amount of cooling water penetrating into the combustion chamber is small, the cooling water can be combusted together with fuel, so that scale deposits appear on the wall surface of the combustion chamber, and heat transfer of heated parts is directly influenced, so that the heated parts are overheated and damaged; if the leakage is severe, the cooling water entering the combustion chamber may even cause a water hammer failure in the diesel engine and be severely damaged. The poor sealing of the sand removal process (hole plug) of the cylinder cover causes the leakage of cooling water, so that the water consumption is increased, and the serious result of the leakage of the cooling water affects the completion of the operation of the locomotive.
And the existing equipment which can carry out air tightness detection on all the opened holes on the whole engine cylinder cover does not exist. Therefore, an engine cylinder head airtightness detection device is provided.
