上海市工业设备安装公司总工程师室和科技部最近对《铜管胀口机》、《连通水平测微阀》、《电管弯管器》进行技术评定。与会者认为,这三个项目均有移动灵活、操作方便、工效提高、劳动强度减轻的特点。经审查一致同意通过鉴定。现将其主要效能简介如下: 一、电动铜管胀口机目前,工业气动仪表管道、民用高层宾馆热水系统等均采用紫铜管胀口承插焊接联接方式。它在工艺上要求先加温退火。若遇6～12毫米的管径尚较省力。而加工16～24毫米管径时就费时、费力。并且要配上氧
The Chief Engineer’s Office and the Ministry of Science and Technology of Shanghai Industrial Equipment Installation Company recently performed technical evaluations on the “copper expansion machine,” “connectivity level microvalve,” and “pipe bender.” Participants considered that all three projects have the characteristics of flexible movement, convenient operation, improved work efficiency, and reduced labor intensity. The review unanimously agreed to pass the identification. Now its main performance is summarized as follows: First, the electric copper pipe expansion machine At present, the industrial pneumatic instrument pipelines, civil high-rise hotels hot water systems, etc. are used copper socket expansion socket welding connection. It requires a warm annealing process first. In case of 6 to 12 mm diameter, it is still more labor-saving. The processing of 16 to 24 mm diameter is time consuming and laborious. And to match oxygen
