一、前言为了配合电磁铁的设计和改进工作,今年四月在一机部主持下经上海红卫电器厂、无锡机床电器厂、安阳机床电器厂、广州机床研究所等单位共同研究确定要将电磁阀的反力特性曲线进行测定,以便提出既具先进性又有代表性的反力曲线,作为电磁铁设计和改进的依据;同时又是作为今后阀生产单位质量检定标准之一。我所于1972年6月和7月将北京液压件厂、南通液压件厂、上海立新液压件厂、大
I. Preface In order to cooperate with the design and improvement work of the electromagnet, in April this year, under the auspices of a department, Shanghai Hongwei Electric Factory, Wuxi Machine Tool Electric Factory, Anyang Machine Tool Electric Factory, Guangzhou Machine Tool Research Institute and other units jointly determined to be The reaction force characteristic curve of the solenoid valve is measured, so as to present both the advanced and representative reaction force curve as the basis for the design and improvement of the electromagnet. At the same time, it is also used as one of the quality standards for valve production units in the future. I am in June 1972 and July will be Beijing Hydraulic Factory, Nantong Hydraulic Factory, Shanghai Lixin Hydraulic Factory, large
