调速阀是进行了压力补偿的节流阀。它由定差减压阀和节流阀串联而成。
节流阀前、后的压力p2和p3分别引到减压阀阀芯右、左两端,当负载压力p3增大,于是作用在减压阀芯左端的液压力增
大,阀芯右移,减压口加大,压降减小,使p2也增大,从而使节流阀的压差(p2-p3)保持不变;反之亦然。这样就使
调速阀的流量恒定不变(不受负载影响)
减压阀芯或节流阀芯在全闭位置时,径向卡住会使出油腔没有流量,在全开位置(或节流口调整好)时,
径向卡住会使调整节流调节部分出油腔流量不发生变化。
另外,当节流调节部分发生故障时,会使调节螺杆不能轴向移动,使出油腔流量也不发生变化。发生阀芯
卡住或节流调节部分故障时,应进行清洗和修复。
(二) 流量不稳定
减压节流型调速阀当节流口调整好锁紧后,有时会出现流量不稳定现象,特别在小稳定流量时更易发生。
其主要原因是锁紧装置松动,节流口部分堵塞,油温升高,进、出油腔小压差过低和进和出油腔接反等。
