空压机上的电磁阀基础知识
Aug
空气压缩机中的电磁阀具有广泛的用途。 电磁阀数量和种类繁多意味着它们几乎可以涵盖任何类型的流体或材料应用。 在本博客中，成都沛丁机电设备有限公司将讨论空压机上的电磁阀基础知识以及电磁阀在空气压缩机中的一些用途。
电磁阀是流体学中最常用的控制元件。他们的任务是关闭、释放、计量、分配或混合流体。它们存在于许多应用领域。电磁阀提供快速安全的切换、高可靠性、长使用寿命、所用材料的良好介质兼容性、低控制功率和紧凑设计。
空压机是用于生产压缩空气的机器。 它由一台由电动机提供动力的活塞式压缩机、一台冷干机和一个储气罐组成。 它的工作原理是空气压缩：从大气中抽取空气，经压缩机压缩后收集到一个罐中。 进气口处装有过滤器，以防止异物进入气缸盖。 冷却盘管去除压缩空气加热产生的冷凝水。
在电磁阀的应用过程中，电磁阀必须处于常开工作状态。 对于小流量，推荐使用直接作用型 RD236（连接 1/4″）和 RB214，因为它们专门用于常开操作。对于大流量，使用先导式电磁阀，如 RB203 型（带有商业连接） 3/8”）推荐。
当系统运行时，电动机运行压缩机，压缩机吸入过滤后的空气，对其进行压缩，将其送到冰箱，最后送到水箱。 在此阶段，电磁阀通电并关闭电路，使其保持在压力下。 当油箱达到要求的压力读数时，压力开关停止电机，单向阀将空气保持在油箱内。 为了防止压缩机在压力下保持太久而损坏，电磁阀然后断电，它允许排出仍然在回路中的多余空气。

电磁阀的不同之处在于它们使用的电流特性、它们产生的磁场强度、它们用来调节流体的机制以及它们控制的流体的类型和特性。该机构从线性动作、柱塞式致动器到枢转电枢致动器和摇臂致动器不等。阀门可以使用双端口设计来调节流量或使用三端口或更多端口设计在端口之间切换流量。多个电磁阀可以一起放置在一个歧管上。阀体必须与流体相容；常见的材料有黄铜、不锈钢、铝和塑料。而且密封件必须与流体兼容。
为了简化密封问题，螺帽、芯、弹簧、遮光环和其他组件经常暴露在流体中，因此它们也必须兼容。这些要求提出了一些特殊的问题。芯管必须是非磁性的，才能将螺线管的磁场传递到螺帽和芯。螺帽和芯需要具有良好磁性能的材料，例如铁，但铁容易腐蚀。可以使用不锈钢，因为它们有磁性和非磁性两种。例如，电磁阀可能使用 304 不锈钢阀体、305 不锈钢芯管、302 不锈钢弹簧和 430 F不锈钢（用于磁芯和螺帽的磁性不锈钢)。
