沈阳电工铸铁厂的XZB148B气动微震压实造型线,采用电-气联合控制,用JLXK_1型行程开关发令,经JZ_7型中间继电器转换接通电磁阀,推动机械动作,实现连续运行。自试生产以来,且已联动生产,但效果达不到设计水平,影响因素很多,其中行程开关因撞击而损坏,也是个关键问题。该厂曾对撞块和开关支架等结构作了改进,但结果仍不理想。又 Shenyang electrotechnical ironworks XZB148B pneumatic microseismic compaction molding line, the use of electric - gas joint control, with JLXK_1 type travel switch order, by JZ_7 type intermediate relay connected to the solenoid valve to promote mechanical action, to achieve continuous operation. Since the trial production, and has been linked production, but the effect of less than the design level, many factors, including stroke switch damage due to impact, is also a key issue. The factory had on the block and switch bracket and other structures made improvements, but the result is still not satisfactory. also
