Precautions for causing burned tiles to fail

<

The preventive measures for burning tile faults are as follows: (1) Select the appropriate model for the use of lubricating oil according to the maintenance regulations, and check the oil level frequently, such as when the engine oil is insufficient. (2) The temperature should be lower when starting. After the friction parts are fully lubricated, the engine is allowed to run at a high speed. (3) Observe the oil pressure gauge while the engine is working. If the oil pressure is low, remove the fault in time; (4) Clean or replace the oil filter cartridge frequently. Prevent oil containing metal chips and other impurities from entering the main oil passage. (5) Sanqin should be done in the normal work: “Careful inspection, diligent inspection, and diligent maintenance”. If the phenomenon of burning tiles occurs before it is repaired, it is a matter of repair methods. The reasons are as follows: (1) The tiles are installed in reverse and the oil channels are blocked; (2) The oil channels are not clean and there are impurities; (3) The main bearing housing is cracked; (4) The bearing and journal are assembled. The contact area is small, even point contact; (5) The coarse filter is installed incorrectly and does not filter; (6) The bending of the crankshaft and the concentricity of the main bearing seat hole are not enough to check, even if the bearing clearance is within the allowable range. Sometimes the individual points are not only without gaps but there may be relative compression, so that the friction surface cannot form a lubricating film during operation. For the above reasons, the following precautionary measures can be taken for the burning of tiles: (1) During the assembly process, care must be taken to pay attention to the passage of lubricant oil, and the shaft journal must have a specified finish; (2) If a clean filter is found, it can be scraped off. The metal shavings should be identified and cleaned and replaced. (3) After assembly, the contact surface of the journal should reach more than 75% of the whole area, and the crankshaft can be rotated flexibly. If there is any contact, it should be scraped. (4) The maintenance of the lubrication system should meet the technical requirements. After starting, observe whether the oil pressure is normal and perform trial operation according to the regulations. After the test run is complete, the oil must be replaced, and the oil filter element must be cleaned or replaced; (5) When the coarse filter is installed The gasket must be pressed tightly. In addition, due to the poor quality of the tile itself and other reasons, it may cause the engine to burn tiles. Specific analysis should be made on the specific issues. The emphasis on prevention during use and maintenance can play a role.
