The rapid development of electronic technology, automation technology in the excavator. In the 1970s, in order to save energy consumption and reduce environmental pollution, easy operation and safety excavator operation, used excavators recycling prices, lower noise excavators, used excavators recycling businesses, improve driver working conditions, gradually electronics and automatic control technology on mining. With the improvement of the efficiency of the excavator, energy saving, easy operation, safety and comfort, reliability and durability and other aspects of performance requirements, prompted the hydraulic integration application on the excavator, and make all kinds of performance has been a qualitative leap . To (to see Table 1), depending on the ambient temperature selection of different grades of oil; diesel fuel is not contaminated with impurities, dust and water, used excavators recovered deal will keep the fuel pump premature wear; poor quality fuel oil in paraffin and sulfur content, Ningbo used excavators recovered, the engine will cause harm; daily job to fill the fuel tank after the fuel tank to prevent the inner wall of water drops; daily work before opening the fuel discharge bottom drain valve; in the engine ran out of fuel After or replace the filter, even though the road to be ranked in the air. Minimum ambient temperature 0 ℃ -10 ℃ -20 ℃ -30 ℃ grades of diesel 0 # -10 # -20 # -35 # used excavators recycling business | Kim Ho used excavators | used excavators recovered from Xi'an, Shanghai Jin Hao Used Construction Machinery Co. company. Shanghai Jin Hao Used Construction Machinery Co. (www.jinhaosh.cn) is the Shanghai Minhang District, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
