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 and killed after the steering wheel excavator price, if at this time able to deflect the front of the machine immediately, and feel no weight, that explanation is a problem with the steering gear Wheeled excavators prices, 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 work of the steering cylinder inability excavator price list, resulting in turn slow. In this regard, can be one-way steady flow valve remote control port base nylon plugs removed, install the pressure gauge; then start the engine of small excavator price, will place the steering wheel to the left or right direction and killed, and the front wheel side is set obstacle; in this case, 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), the fault can be excluded.泰安嘉 and Heavy Machinery Co., intelligent environment 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 domestic users of the mining machinery quality requirements are high, 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. Clearly, as mechatronics 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.
