A survey of energy saving mechanical potential of Chinese Academy of Sciences recently released show that China is one of the world's natural resources to waste the most affected countries, ranked 56 in the 59 countries surveyed. Construction machinery industry as the internal combustion engine product except the automobile industry the second largest use of industry, although the scope of work is limited to the construction, mining and construction sites and other excavators prices, but because of its emission intensity, emission targets and inferior to the car, so the environment The more pollution. 90 excavator for this price, the State Council "on the strengthening of the internal combustion engine of industrial energy saving advice" in the clear requirements early in 2013, by 2015, energy-saving products accounted for 60% of the internal combustion engine combustion engine product ownership society, the internal combustion engine fuel consumption rate decreased 6% -10%. China Construction Machinery Industry Association, Qi Jun excavator price list indicates that China is "the world's largest construction site," construction led the rapid development of construction machinery industry. However, the requirements of the relevant construction machinery products have been relatively relaxed emissions, which makes the market is flooded with a large number of high-emission products, it has become a heavy burden on the environment of our country. Therefore, Qi Jun believe that China's construction machinery industry in energy saving policy-oriented, market demand for double-level will face an important opportunity, in 2013 the State has a series of policies to support the development of environmental protection industry into the implementation phase, 2014 to versatility, miniaturization Smart EFI represented energy saving construction machinery industry will drive growth of over 25%. According to the 2013 annual country report of the Government clearly shows that China's annual energy reduction targets if not completed. Statistics show that efficiency of energy use is only US 26.9%, Japan 11.5%. State "Industrial Energy Efficiency" second five "plan" shows that the overall objective of industrial energy: By 2015, above-scale industrial added value of energy consumption decreased by about 21% compared with 2010. States make stringent requirements of engineering machinery enterprises have put their energy efficiency and environmental protection strategy in an important position. In addition, in the present construction of the new town become a source of economic growth for a long period of time, the energy saving will boost the construction machinery market has a positive effect. Crawler excavators turned sluggish troubleshooting method (1) Check the steering pump steering pump leak if severe, can also cause the machine to turn slowly. An important reason to cause the steering pump leak is small excavators price list, the gap side of the pump rotor and vanes and side end surface is too large (normal clearance should be less than 0.047mm, the maximum should not exceed 0.100 mm). Check is: In the case of the steering cylinder, the central rotary joint and steering performance are intact, dress a new pump to do comparison tests; such as dress up turning good performance, then prove that the fault is with the steering pump should be replaced The new pump. (2) Check the central rotary joint when the central rotary joints excavator inner cylindrical surface or seals badly worn, will make through the entire oil and gas system of collusion in the swivel joint at seal failure, resulting in a swivel joint operation of each system not sensitive. When the machine is steering, high-pressure oil leaking into the gas path or in the other (suspension, legs, etc.) of the hydraulic lines, so that the supply of hydraulic steering cylinder fuel reduced, resulting in slow movement steering cylinder. Check the approach is: flip up the wheel brake manual gas switch, if it contains oil mist ejected from the inside gas, then the central rotary joint due to severe wear has enabled oil to leak into the gas path. In this case, replace the central rotary joint seals and repair central rotary joint.泰安嘉 and Heavy Machinery Co., Ltd. 90 excavator price | Kerry and Heavy | Wuhan excavator price offered by 泰安嘉 and Heavy Machinery Co., Ltd ..泰安嘉 and Heavy Machinery Co., Ltd.
