Rexroth先导式三位四通伺服换向阀的特征:先导式 4/3-伺服换向阀 NG10 ~ NG35,遮盖度约为 20 %; 先导阀 NG6,配有控制阀芯和阀套,伺服性能可靠,但电磁铁驱动操作,4位4通,断电时处于 Fail-safe 功能位置;控制电磁铁配有电子位置反馈器和位移传感器的电子控制器 (Lvdt DC/DC);主级配有位置反馈器;线性行程滑阀,配有防扭转装置;流量特性:S = 曲线渐增式,NG16, 25, 27,带有负载分接头 C1/C2 ;用于阀板安装, NG10 接口的位置符合ISO 4401-05-05-0-05, NC16 接口的位置符合 ISO 4401-07-07-0-05,NG25/27 接口的位置符合ISO 4401-08-08-0-05,NG35 接口的位置符合 ISO 4401-10-09-0-05 ;安装板根据规格参数表,NG10 RC 45055, NG16 RC 45057, NG25/27 RC 45059 和 NG35 RD 45060(单独订购);插头式连接器符合 DIN 43560-AM2,电磁铁 2P+PE/ M16x1.5,位移传感器 4P/Pg7 含在供货范围内;外接电子控制器(单独订购),电子放大器,用于标准特性曲线,没有斜坡,电子放大器,有斜坡和死区补偿 Rexroth配有电子位置反馈器的先导式三位四通伺服换向阀由 2 个主要部件构成:先导阀(1),配有控制控制阀芯和阀套、回位弹簧、控制电磁铁和感应式位移传感器;主级(2),配有对中弹簧和位置反馈器 功能说明:当没有操动控制电磁铁时,先导阀的控制滑阀在弹簧力作用下处在“Fail-Safe”功能位置中,主级滑阀处在其弹簧对中的中间位置。在集成电子控制器中将设定值与主级控制滑阀的位置实际值进行比较。 如果存在控制偏差,就会驱动控制电磁铁,以改变磁力的方式对先导滑阀进行调整。 经过控制截面的体积流量使得主控制滑阀移动。 如果将设定值设置为 0 V,则主级的控制滑阀就会在对中弹簧作用下保持在被遮盖的中间位置。要么在内部通过接口 P,或者在外部通过接口 X 将控制油供应给先导阀。 可以在内部通过接口 T 或者在外部通过接口 Y 回流到油箱。 电源故障:如果发生故障,或者当电缆断线时,集成式电子控制器就会将控制电磁铁断电,先导滑阀进入“Fail-Safe”功能位置,并且将主级的控制油腔卸空。 主级控制滑阀在弹簧作用下进入中间位置。 Rexroth力士乐先导式三位四通伺服换向阀的部分常用型号: 4WRL10E80S-3X/G24Z4/M 4WRL10E80S-3X/G24EZ4/M 4WRL10E80S-3X/G24ETZ4/M
