Excavator maintenance taboo: the indiscriminate use of butter and butter graffiti pad cylinder. Butter is commonly used in engineering machinery repair grease, can play the role of lubrication and sealing. Therefore, some mechanic during the installation of the cylinder pad, the pad will be in the cylinder coated with a layer of butter, that this would increase the tightness of the diesel engine. As everyone knows, but doing so affects the performance of the diesel engine. Cylinder pad is the most important between the diesel engine block and the cylinder head seals, it will not only be able to seal high-temperature high-pressure gas cylinders produced, but also seals the cylinder head and the cylinder of the cooling water and lubricating oil, so While working cylinder pad, should pay special attention to its sealing quality. Cylinder pad butter during the installation, when the cylinder head bolt tightening, some butter will be squeezed into the cylinder waterways and oil passages in the cylinder head gasket to remain in butter between the cylinder at work, due to high temperature, some will flow people cylinder combustion and partly remains in the binding surface of the cylinder block and cylinder head, the cylinder pad, resulting in a gap between the price of Xi'an 90 mini excavator cylinder head and the body plane, the impact of high temperature and high pressure gas cylinder head gasket is easy from here, Xi'an destroyed cylinder head gasket 90 mini excavator price, resulting in leakage. In addition, a long time in the butter will produce coke at high temperatures, resulting in premature aging deterioration cylinder head gasket. So do not buttering installation cylinder head gasket.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. EFI technology with intelligent Hou Xian 90 mini excavator price, can significantly improve the utilization of engine power, reducing the hydraulic system power loss Xi'an 90 mini excavator price, so that the power system and the load better match the required power and reduce engine and work intensity of hydraulic components, thereby increasing the reliability of the equipment in long-term use of the whole. 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.
