Intelligent environmental fuss around in the stimulation of national policy on the one hand, the domestic construction machinery market threshold gradually, the whole construction machinery industry structure contention also by the economic and durable products continuously adjusted toward intelligent environmental protection. Major construction machinery enterprises have also increased investment in technical innovation and new efforts to promote construction machinery manufacturers agreed action also means that the industry transition to a green, smart, "energy saving, environmental protection" has been infiltrated into the industry as a whole in. On the other hand, the quality of domestic users increasingly demanding mining machinery excavator price list, especially for product efficiency, fuel consumption, maintenance, salvage and other indicators are very concerned about. Doosan Infracore related to this high level stressed excavator industry generally use EFI engine direct injection engine to replace the original purpose is not simply to improve fuel efficiency to reduce fuel consumption so simple, why the industry recognition EFI engine is the industry's future, its more central significance lies around EFI technology has a range of intelligent control technology to be applied, only the intelligent control of fuel injection is the key to cost reduction achieved. With industry data show that nearly 40 percent of construction machinery from the hydraulic system failure, about 15% of the fault from the engine. With intelligent EFI technology, can significantly improve the utilization of engine power, reduce hydraulic system power loss, so that the power system and the load better match the required power and reduce the engine and hydraulic components work intensity, thereby increasing the overall Equipment reliability in long use. Obviously the price of domestic excavator, with mechatronics technology widely used in construction machinery, intelligence has become a trend of construction machinery. Host manufacturers to highlight EFI technology itself, but also attaches great importance to information technology research excavator, fault recording and diagnostic systems. Excavators turned sluggish troubleshooting method (1) Check steering motor when the steering motor stator and rotor rotary valve Face Face or badly worn, will actually turn into the high-pressure fuel tank due to reduced steering action slow. If the steering cylinder, the central rotary joint performance intact, you can turn off the engine after the steering wheel in the dead, at this time if the machine's front wheels can immediately deflection mini excavator price, and feel no weight, that explanation is steering a problem , and should immediately repair or replacement. (2) one-way check valve when a steady flow of oil pressure in the hydraulic steering system steady flow due to one-way valve spring force weakened too, will make the steering cylinder inability to work, resulting in turn slow. In this regard, it can be one-way steady flow valve remote control port base nylon plugs removed, install the pressure gauge; then start the engine, the steering wheel to the left or right direction in situ killed and obstacles in the front side thing; this time, watching the pressure gauge readings, if pressure is less than 7Mpa, they should be one-way steady flow adjustment screw inside the valve properly (you must first loosen the fixing nut), failure can be ruled out.泰安嘉 and Heavy Machinery Co., Ltd. 90 excavator price, Kerry and heavy industry, Tongchuan excavator price offered by 泰安嘉 and Heavy Machinery Co., Ltd ..泰安嘉 and Heavy Machinery Co., Ltd.
