近些年来,真空技术已开始应用到起重运输作业方面,我国已有很多单位采用真空吸盘搬运物料,例如;上海造船厂用真空吸盘吸运船身;太原钢厂用真空吸盘吸运钢板;北京砖瓦厂、市政一公司用真空吸盘吸运砖块等等。但是,这些真空吸盘均靠动力源产生真空度,需要附加真空泵、压缩空气、管路、阀等一套 In recent years, vacuum technology has been applied to the lifting and transport operations, many units in our country have adopted vacuum suction cups to carry materials, for example; Shanghai Shipyard vacuum suction suction hull; Taiyuan Steel vacuum suction cups steel plate; Beijing brick factory, a municipal sucker with a vacuum suction brick and so on. However, these vacuum cups depend on the power source to generate vacuum, which requires an additional vacuum pump, compressed air, piping, valves, etc.
