Marine diesel fuel in the combustion chamber to ignite, generate high pressure gas. In the gas piston driven, Weifang Huadong ship machines wholesalers, descends from the upper external work only. Piston down until the vent open (in this case in crank position, the gas expansion work at this end, a large number of in-cylinder exhaust gas on its own high-pressure free, people from the exhaust port to the exhaust pipe of a diesel engine bush-burning editor It is not a seasonal use of lubricants. Different seasons should use different grades of oil. Some diesel bush-burning, is the result of summer using a small viscosity oil in the bush can not form a film due to the contact surface. The second is the lubricant unclean . If dirty oil added to the body, Weifang Huadong boat engine service, it will cause clogging of the oil bush-burning. Third, pay attention to observe the instrument when the diesel engine oil pressure should be normal (0.15 ~ 0.25) MPa of Room idling engine oil pressure not less than 0.5MPa. Many machine hand rarely pay attention to see the oil pressure gauge, and therefore can not be found hidden faults. The fourth is to add the right amount of oil is not. If the oil is too easy to burn the oil when the engine is running, Shandong EAST ship machine retailers, the formation of carbon, if it is too small, it will cause poor lubrication and bush-burning axle. Usually the oil surface in the most appropriate scale up and down between the dipstick. Fifth, long-term overload caused by bush-burning. due to long-term overload operation, engine temperature, low speed, east ship machines, bush bearing capacity increases, a corresponding reduction in the fuel supply pump, combined with lower oil viscosity at high temperatures, more likely to cause bush-burning. Sixth axis and tile fit gap does not meet the standard gap is too small, the oil is not easy to enter, can not form a film layer, the gap is too large, easy to drain the oil, the oil film layer is difficult to form. Therefore, in the repair assembly bearing clearance must be guaranteed within the standard range.
