節(jié)流閥和單向節(jié)流閥是簡易的流量控制閥，它們在定量泵液壓系統(tǒng)中的主要作用是與溢流閥配合，組成三種節(jié)流調(diào)速系統(tǒng)：即進油節(jié)流調(diào)速系統(tǒng)、回油節(jié)流調(diào)速系統(tǒng)和旁路節(jié)流調(diào)速系統(tǒng)。對于執(zhí)行元件要求往返節(jié)流調(diào)速的系統(tǒng)可使用兩個單向節(jié)流閥。節(jié)流閥也在容積節(jié)流調(diào)速回路中使用。這種閥沒有壓力及溫度補償裝置，不能自動補償載荷及油液粘度變化時造成的速度不穩(wěn)定，但其結(jié)構(gòu)簡單，制造和維護方便。所以在載荷變化不大或?qū)λ俣确€(wěn)定性要求不高的一般液壓系統(tǒng)中得到應(yīng)用。下面是SKF軸承裝配的一些相關(guān)事項。外圈的裝配事先在外殼的圓周上設(shè)置幾處外圈擠壓螺桿用螺絲，裝配過盈配合的外圈。一面均等地擰緊螺桿，一邊裝配。這些螺桿孔平常蓋上盲塞，SKF軸承等的分離型軸承，外殼擋肩上設(shè)置幾處切口，使用墊塊，用壓力機拆卸，或輕輕敲打著拆卸。圓柱孔軸承的裝配可以用壓力機械拔出簡單。此時，內(nèi)圈的裝配。要注意讓內(nèi)圈接受其拔力。以使易于拉拔。寬度大的軸承則油壓法與拉拔卡具并用，大型軸承的內(nèi)圈裝配采用油壓法。

排除方法：添加液壓油一般數(shù)控臥式加工中心安裝在機加工車間，不僅環(huán)境溫度變化大，使用條件差，而且各種機電設(shè)備多，致使電網(wǎng)波動大。安裝加工中心的位置，需要電源電壓有嚴格控制。電源電壓波動必須在允許范圍內(nèi)，并且保持相對穩(wěn)定。否則會影響加工中心數(shù)控系統(tǒng)的正常工作。數(shù)控臥式加工中心的環(huán)境溫度低于3攝示度，相對溫度小于8%。一般來說，數(shù)控電控箱內(nèi)部設(shè)有排風(fēng)扇或冷風(fēng)機，以保持電子元件，特別是處理器工作溫度恒定或溫度差變化很小。
