《郑国伟、文德邦主编的《设备管理与维修工作手册》中,在“设备维修的技术管理”篇章的附件三“锻压设备大修理通用技术条件”2.12条款规定:锻锤垫木排的材质应符合技术要求,木材的绝对含水率不得超过25%。对此含水率根据我们的调查和工作实践提出如下意见,以作垫木施工和修订安装规范时参考。在60年代初期我们安装1t自由锻锤和3.15t模锻锤时,按设计和安装规范要求垫木的相对含水率不
In the “Manual for Equipment Management and Maintenance” edited by Zheng Guowei and Wen Debang, the “General Technical Conditions for Heavy-duty Repair of Forging Machines” in Chapter 3 of the “Technical Management of Equipment Maintenance” section stipulates: the material of the hammer hammer pad Should meet the technical requirements, the absolute moisture content of wood must not exceed 25%. This moisture content is based on our investigation and work practices and puts forward the following opinions for reference when making construction and revision of installation specifications.
