Excavators filter common use of knowledge and maintenance of oil filters role is to filter sludge in the engine, engine oil impurities arising from the deterioration of their own to prevent oil deterioration, minimize wear under the various components during operation of the general situation, engine oil filter change intervals for the first 50 hours of the replacement, then every 250 hours of work to be replaced. Oil, fuel filters Frequently Asked Questions 1. Under what circumstances requiring replacement of oil filter, fuel filter? Fuel filter is the removal of the fuel in the iron oxide, dust and other magazines, to prevent clogging of the fuel system, reduce mechanical wear, to ensure the stability of the engine run. Under normal circumstances, the engine fuel filter replacement cycle for the first time to work 250 hours replacement, then every 500 hours to replace, the specific time should be flexible depending on the fuel quality replacement levels. When the filter pressure gauge indicates alarm or abnormal Lianyungang used mini excavator price, you need to check whether there are anomalies filter, if any, must be changed. When the filter surface deformation of a leak or rupture, you need to check whether there are anomalies filter, if any, must be replaced. 2. Whether the higher filtration precision oil filter better? For an engine or equipment, a proper cartridge filter accuracy should achieve a balance between filtration efficiency and dust capacity. Use high filtering accuracy of the filter, it may be because of low dust capacity cartridges resulting in shortened life of the filter, thereby increasing the risk of premature clogged oil filter. 3. The low-grade oil, fuel filters and pure oil, fuel filters the role of equipment What is the difference? Pure oil, fuel filters can effectively protect the equipment, prolonging the life of another, inferior oil, fuel filters can not be good protective equipment, can not extend the life of equipment, or even worsen usage of equipment. Taian Jia and Heavy Machinery Co., winter digging machine park needs maintenance skills 1, if the excavator surface soil we must clean up, check for loose fasteners. 2, check the antifreeze level and oil level is normal, check the oil quality is normal, check the fuel level of antifreeze. 3, if the weather is particularly cold, excavator downtime is very long, set the engine cooling fluid drained. At the same time in order to prevent the battery feed, you must remove the battery storing it in a warm place. 4, from time to time between start once the engine is running, if the antifreeze level and oil level is lower than normal oil level, please do not hesitate to add to normal after the start. Key in the cold weather to preheat position to preheated lights (were repeated preheating), and then start the engine, idle for 5-10 minutes after the no-load operation of each cylinder movement 5-10 times than the maximum small stroke 5-10MM. Finally the engine revolution speed up fast operating each cylinder movement 5-10 times Lianyungang used mini excavators prices, while operating turn around and walk back and forth three times each. Until the system temperature rose to 50-80 degrees before normal operation, continue to make all of the work means each movement 5-10 minutes after stopping the engine. 5, to replace the diesel models is -10 to -30, depending on the region where the more northerly areas necessary to add - No more diesel, in addition to replacing the fuel filter Lianyungang used mini excavators prices, oil To replace the applicable local thickening oil, oil filter replacement Lianyungang also used mini excavators prices, oil spills where the hydraulic system should be promptly replaced, conditional tank insulation to do. 6, cooling system hoses to carefully check whether the aging and broken, if there are questions to be replaced because these places in winter are more prone to problems. If the conditions provide hot water heating tank of water per day it is best to launch this better engine, but must be careful not to forget to turn on the water. Why we do not advocate adding antifreeze is antifreeze in particular because of the additional cold areas are less likely to start the engine.泰安嘉 and Heavy Machinery Co., Ltd.
