力士乐流量阀2FRM6B76-3X/16QMV
流量控制阀 利用调节阀芯和阀体间的节流口面积和它所产生的局部阻力对流量进行调节,从而控制执行元件的运动速度。流量控制阀按用途分为 5种。(1)节流阀:在调定节流口面积后,能使载荷压力变化不大和运动均匀性要求不高的执行元件的运动速度基本上保持稳定。(2)调速阀:在载荷压力变化时能保持节流阀的进出口压差为定值。这样,在节流口面积调定以后,不论载荷压力如何变化,调速阀都能保持通过节流阀的流量不变,从而使执行元件的运动速度稳定。(3)分流阀:不论载荷大小,能使同一油源的两个执行元件得到相等流量的为等量分流阀或同步阀;得到按比例分配流量的为比例分流阀。(4)集流阀:作用与分流阀相反,使流入集流阀的流量按比例分配。(5)分流集流阀:兼具分流阀和集流阀两种功能。

阀门安装
(1)阀用联接螺钉的性能等级必须符合制造厂的要求,不得随意代换。联接螺钉应均匀拧紧(勿用锤子敲打或强行扳拧),不要拧偏,最后使阀的的安装平面与底板或油路块安装平面全部接触。
(2)应注意进油口与回油口的方位,某些阀如将进油口与回油口装反,会造成事故。有些阀件为了安装方便,往往开有同作用的两个孔,安装后不用的一个要封堵。
(3)液压阀的安装方式应符合制造厂及系统设计图样中的规定。
(4)板式阀或插装阀必须有正确的定向措施。
(5)为了保证安全,阀的安装必须考虑重力、冲击、振动对阀内主要零件的影响。
(6)方向阀一般应保持轴线水平安装;
(7)一般需调整的阀件(如流量阀、压力阀等),顺时针方向旋转时,增加流量、压力,逆时针方向旋转时,则减少流量、压力。

电磁铁的性能指标主要包括适用电压(电流)、推(拉)力和行程等。
根据电压可以分为12V直流,24V直流,110V交流,220V交流等。NG6阀用电磁铁推拉力一般为20-
70N,行程在 3-7mm之间。当怀疑某电磁阀卡滞或线圈烧毁时,可以将电磁阀反过来,看其行程是否
在上述范围之内。
电磁铁的外特性主要表现为电阻。最常见的24V NG6电磁阀线圈阻值一般在16-26Ω之间,24V插装
阀线圈阻值一般在20-38Ω之间,24V比例阀线圈阻值一般在21-26Ω。理论上,电磁吸力与电流的平
方成正比,所以12V线圈阻值一般为对应24V线圈的1/4左右。
比例电磁阀一般要求电流达到某一范围。如REXROTH(力士乐)系列泵用24V比例电磁阀一般要求电
流200-600mA,12V的要求电流400-1200mA。LINDE系列泵用24V比例电磁阀要求电流220-405mA或175-
360mA。SAUER系列泵用24V比例电磁阀要求电流13-85mA。
