4WE6D6X/OFEG24N9K4直流24V电磁阀

电磁换向阀

工作原理:

利用电磁铁的通电吸合与断电释放而直接推动阀芯来控制液流方向的。

类型:

交流(D,36V或220V或380V)

直流(E,24V或100V )

干式、湿式

交流电磁铁:使用电压为交流110、220、380V。特点是启动力非常大，不需要专门的电源，吸合、释放快，动作时间约为0.01 ~0.03s。缺点是电源电压下降15%以上，电磁铁吸力明显减小，若衔铁不动作，干式电磁铁会在10~15min (湿式1~1.5h) 后烧坏线圈，且冲击及噪声非常大，寿命低，允许切换频率为10次1分。

直流电磁铁:使用电压为直流110和24V,工作可靠，吸合释放时间约为0.05~ 0.08s,切换频率般为120次/分，冲击小、体积小、寿命长，但需要专门的直流电源，成本较高。

交流本整型电磁铁:电磁铁是直流的，电磁铁本身带整流器，通入交流电经整流后再供给直流电磁铁。

干式电磁铁:电磁铁线圈、铁芯与轭铁处于空气中而不和油液接触。电磁铁与阀连接时，在推杆处设置密封圈，避免了油液进入电磁铁，而且装拆方便。为了防止回油进入干式电磁铁中，要求换向阀的回油压力不能太高。

湿式电磁铁:湿式电磁铁的推杆与阀芯连成一体,取消了推杆处的动密封，所以摩擦力小，复位性能好，冷却润滑好，工作寿命长。

电磁线圈是通电产生电磁的一种装置。在铁芯的外部缠绕与其功率相匹配的导电绕组，这种通有电流的线圈像磁铁一样具有磁性，它也叫做电磁铁（electromagnet）。我们通常把它制成条形或蹄形状，以使铁芯更加容易磁化。另外，为了使电磁铁断电立即消磁，我们往往采用消磁较快的的软铁或硅钢材料来制做。这样的电磁铁在通电时有磁性，断电后磁就随之消失。

电磁铁烧毁

1.电源电压比电磁铁规定的使用电压高而引起线圈过热。

2.推杆伸出长度过长，与电磁铁的行程配合不当，电磁铁衔铁不能吸合，使电流过大，线圈过热。当一个电磁铁因其他原因烧毁后，使用者自行更换电磁铁时更容易出现这种情况。由于电磁铁的衔铁与铁芯的吸合面到与阀体安装表面的距离误差非常大,与原来电磁铁相配合的推杆的伸出长度就不一定能完全适合更换后的电磁铁。如更换后的电磁铁的安装距离比原来的短，则与阀装配后，由于推杆过长，将有可能使衔铁不能吸合，而产生噪声，抖动甚至烧毁。如果更换的电磁铁的安装距离比原来的长，则与阀装配后，由于推杆显得短了,在工作时，阀芯的换向行程比规定的行程要小，阀的开口度也变小，使压力损失加大，油液容易发热，甚至影响执行机构的运动速度。因此，使用者自行更换电磁铁时，必须认真测量推杆的伸出长度与电磁铁的配合是否合适，绝不能随意更换。
