mini excavator track rollers

Replacement time of kobelco fuel filter: Hydraulic excavators generally need to be replaced after 2000 hours of operation, otherwise the system will be polluted and cause system failure. According to statistics, about 90% of hydraulic system failures are caused by system pollution. In addition to checking the color, viscosity, and smell of the oil, it is also necessary to check the oil pressure and air humidity. If you work in a higher altitude and lower temperature environment, you must also pay close attention to the carbon content, colloid (olefin) and sulfide in the engine oil, as well as the impurities, paraffin and moisture content in the diesel. In special circumstances, if the machinery uses low-grade diesel oil (sulfur content in diesel oil is 0.5﹪～1.0﹪), the kobelco fuel filter and machine filter should be replaced every 150h; Machine filter. Use crushers, vibratory rammers and other equipment that have a heavy load on the hydraulic system. The replacement time of the hydraulic oil return filter, pilot filter and respirator filter is every 100h. Cost-effective fuel filtration does not equate to cutting corners We pay attention to every little detail (to save you from worries) We use quality components to manufacture quality filters - both high-end and standard models

What are the differences between the friction-welded mini excavator track rollers and the traditional type of track roller? 1.Friction-welding mini excavator track rollers is better in the wear-resistance and has longer working lifetime. 2.Consumption of material For traditional track roller, the roller bodies are connected by the welding rod. For friction-welding mini excavator track rollers, the roller bodies are connected by the friction between roller bodies.Friction part of roller will be added more material to make sure roller is conformed to the standard size after friction-welding. 3.Interior parts For traditional track roller, the welding is done after two processes of fine machining, therefore the requirement to the size of interior parts is not that severe. For friction-welding track roller, after the welding, there is one more fine ma-chinning with concentric locating to make sure the conformity of inner sizes.And for which, the requirement to the size of interior parts is severe.Interior parts for friction-welding track roller are with higher standard. 4.Differences on the manufacturing processes
