挖掘机是工程机械中使用最广泛的机种,社会保有量很大。挖掘机的结构日趋复杂,维修难度也越来越大。在实际维修过程中,面临的最大困难是缺乏挖掘机维修资料,尤其缺乏各种机型的精准液压图和电路图。《挖掘机液压图和电路图集》则正好满足了这一需求。本图集由辽宁科技出版社出版,由马德水主编,高衡主审,副主编为朱齐平、于新、李清源、周兴业。 Excavators are the most widely used type of construction machinery, a great social possession. The structure of excavators is becoming more and more complicated, and the difficulty of maintenance is also getting bigger and bigger. In the actual maintenance process, the biggest difficulty is the lack of excavator maintenance information, in particular, the lack of precision models of various types of hydraulic diagrams and circuit diagrams. “Excavator hydraulic diagrams and circuit atlas” just to meet this demand. The Atlas is published by Liaoning Science and Technology Press, edited by Mr. Ma Shui and examined by Gao Heng and co-edited by Zhu Qi-ping, Yu Xin, Li Qingyuan and Zhou Xingye.
