巨型全钢工程机械子午线轮胎成型机新型定型鼓压力控制装置的设计

摘要

This paper introduces the new drum pressure control device for giant OTR radial tire building machine.Pneumatic control system consists of pneumatic diaphragm valves,purge diaphragm valves, pressure switches,left lock electromagnetic valve and right lock electromagnetic valve.The pressure is detected by a pressure switch and two diaphragm values and two electromagnetic values are controlled by programmable logic controller(PLC).This new device enables control of green tire position,inflating and deflating process,gas pressure level,and internal pressure level even at the circumstances of power outage and/or gas shutoff.%介绍巨型全钢工程机械子午线轮胎成型机新型定型鼓压力控制装置的设计。新型定型鼓压力控制装置的气动控制系统由充气膜片阀、放气膜片阀、压力开关、左锁定电磁阀和右锁定电磁阀等组成，压力开关检测压力，可编程控制器对两个膜片阀和两个锁定电磁阀进行控制。该装置实现了对定型胎坯固定、充气和放气及定型压力控制、停电或/和停气时保证内压的目的。
