技术介绍
空气压缩机是一种用以压缩气体的设备。空气压缩机与水泵构造类似。大多数空气压缩机是往复活塞式,旋转叶片或旋转螺杆。离心式压缩机是非常大的应用程序。由电动机直接驱动压缩机,使曲轴产生旋转运动,带动连杆使活塞产生往复运动,引起气缸容积变化。由于气缸内压力的变化,通过进气阀使空气经过空气滤清器(消声器)进入气缸,在压缩行程中,由于气缸容积的缩小,压缩空气经过排气阀的作用,经排气管,单向阀(止回阀)进入储气罐,当排气压力达到额定压力0.7MPa时由压力开关控制而自动停机。当储气罐压力降至0.5--0.6MPa时压力开关自动联接启动,而空气压缩机就是提供气源动力,是气动系统的核心设备,机电引气源装置中的主体,它是将原动(通常是电动机或柴油机)的机械能转换成气体压力能的装置,是压缩空气的气压发生装置。对于三相交流电的压缩机而言,如果在供电电力系统中出现不平衡负荷,三相电压或电流不平衡会对电力系统和用户造成一系列的危害,比如不仅造成对、电动机、变压器、继电保护和自动装 ...
