Cause pistonring scrapes the lecture to cause of the destruction caused by the lubricating oilfilm amid piston auditorium and cylinder. The main influencing factors are: thepiston and the cylinder next the gap is too small; piston field assemblyimproper assembly pardon to compression or stretching caused by the mouth ringdeformation; wrong assembly cylinder or adapter cylinder head, causing theliner deformation; The diesel engine long-term operation at high temperatures,causing the lubricant film break ring; Insufficient grease or seriouspollution.
Maximizethe use of hot begin following the engine starts; taking into account the operation of the dieselengine in winter the temperature should be maintained within the usual range,prohibit Meng throttle provoked warming emergency brake parking, and otherharmful habits; to prevent the load surge at low temperatures, fierce reductionand long idle, and to minimize the number of cool start. truly good job in theoperation of diesel engines organization in the supplementary robot and overhaul work,mechanical put-on to maintain a sober swiftness and a reasonably priced load.
Strengtheningthe "filter" and the timely replacement of the filter. Information,1g of dust into the cylinder allows the cylinder the upper wear 0.01mm, appropriately thatthe piston wear 0.75g and piston sports ground wear 0.009mm. appropriately must be irritated upon aregular basis to preserve the air filter, oil filter, diesel filter.
Properselection, inspection and replacement of oil should be used in the similar batch,same manufacturer, thesame viscosity and atmosphere grades of lubricants is strictlyprohibited lubricant mixture of swap viscosity and mood grades, filling theelection in no wind, pollution-free occasion. to prevent dust and water and othercontaminants from entering.
Thecorrect selection should be based on climatic conditions and the play a role ofdiesel engine fuel, and seriously calibration and familiarization of the fuelinjector fuel injection pressure and injection pump fuel supply give support to angleto ensure the operation of diesel engines in the best state.
Avoidthe diesel engine without the cooling water starts or prolonged overheatingstate operation, forbidden the filling in the diesel engine operatingtemperature is too high, coolant or water to wash the body.
2.2improve the mood of diesel engine repair
Strengthen the parts clean and pollution prevention in each processmatching and assembly work. exact matching and assembly of the piston ring.High-speed diesel engine piston ringauto dvdand car dvd playersurface plated chromium, molybdenum, andother spray process, prohibit the use of grinding field to trim the"backlash"; application of special tools to install piston rings,piston arena opening should be forbidden from clear progress and compression, toprevent the assembly methods of inadequate piston arena distortion; piston rodassembly into the cylinder vivaciously pounding the prohibition to prevent thepiston arena and cylinder crash and cause damage, cracks and stressconcentration.
