Check the excavator oil oil: In addition to changing the oil in accordance with the requirements, the daily check the oil level when the engine oil quality can be checked immediately if unusual oil change. Note that if the inspection process oil emulsion (milky or white, there is a bubble), whether sour smell, whether thinning or thickening the viscosity was observed. What factors influence oil consumption? 1. workload: truck oil consumption than large cars, and construction machinery larger than the oil consumption of the truck; the greater if the same construction machinery, engine load, the higher the temperature, the viscosity of the oil to diminish, into the combustion chamber loss of oil is also more. 2. The impact of operating conditions: overheating or preheat proceeds at full speed. If you continue to use this operating mode, such as pistons or cylinder liner wear will increase, resulting in increased oil consumption, engine power output drops. 3. The air filter and oil filter replacement neglect, dirty air, contaminated oil can cause abnormal wear of the piston or cylinder liner, thereby increasing oil consumption. 4. If the use of poor quality fuel, the combustion chamber will produce carbon and some harmful substances can cause abnormal wear of the piston and cylinder liner, so that oil consumption increases. 5. The machine vibrations: the machine is inclined or uneven local jobs, rocking back and forth inside the oil sump, the impact of high-speed rotation of the crankshaft, the formation of mist emanating from the vent to the outside. Governance overheating technical measures (1)? Freestanding fan instead of conventional models fan mostly non independent mechanical connection type, namely by the diesel engine crankshaft through a fan belt wheel and tape drive used excavator price, fan speed and crankshaft speed Synchronize. This way when the low speed and high load conditions, insufficient cooling air flow fan, easily lead to overheating when a large load of construction machinery; the way in the high-speed low load conditions, the fan speed operation, cooling air is too large, easily lead when a small load of construction machinery too cold. (2)? The radiator instead Split - traditional radiator group (module) from the water radiator, hydraulic oil cooler, torque converter oil cooler, oil cooler and so on successively in series into a group, mounted on the front fan. This installation type has the following disadvantages: a plurality of radiator cooling fan shared a homemade mini excavator price, not according to their specific target cooling temperature cooling; a plurality of radiators connected in series, so that the cooling air through each radiator The flow resistance increases, and the cumulative effect of heat, cold reduced and radiator coolant temperature, reducing the cooling effect. Shandong Highway Engineering at a traditional cooling system ZL50 type loader has been transformed. The use of dual output shaft of the hydraulic motor are driven radiator fan and water pump installed in the front of the engine, radiator water cooling excavator price, consisting of a module; hydraulic oil cooler from the cooling fan, radiator and water separation Prices of small and medium excavators, installed in the engine on the other side composed another module. Its hydraulically driven fan and electric fans, are used ECV intelligent control, according to their desired speed cooling. (3)? Improved heat sink material and arrangement in recent years, at home and abroad to develop new materials with aluminum radiator foam, graphite foam and aluminum, such as several, including the United States developed a graphite foam material spherical graphite network like structure, the contact surface is large, has a very high thermal diffusivity, heat transfer coefficient higher than conventional copper radiator. Aluminum radiator light quality, good corrosion resistance, heat dissipation is 106% copper heat sink.
