調(diào)壓步驟
1、關(guān)閉減壓閥前的閘閥,開啟減壓閥后的閘閥,制造下游低壓環(huán)境;
2、將調(diào)節(jié)螺釘按逆時針旋轉(zhuǎn)至最上位置(相對最低出口壓力),然后關(guān)閉減壓閥后閘閥;
3、慢慢開啟減壓閥前的閘閥至全開;
4、順時針慢慢旋轉(zhuǎn)調(diào)節(jié)螺釘,將出口壓力調(diào)至所需要的壓力(以閥后表壓為準(zhǔn));調(diào)整好后,將鎖緊
螺母鎖緊,打開減壓閥后閘閥;
5、如在調(diào)整時出口壓力高于設(shè)定壓力,須從第一步開始重新調(diào)整,即只能從低壓向高壓調(diào)。期正常工作。
使用技巧
在設(shè)定機(jī)械泵的驅(qū)動壓力時,正確的方法是使驅(qū)動壓力高于背壓1-1.

減壓閥
5kg/cm2(15-20psig)。這在大多數(shù)情況下是正確的。但有時為達(dá)到泵的要求排量,需要將驅(qū)動壓力設(shè)得稍高一些。驅(qū)動壓力高時,不利的一面是容易對進(jìn)氣閥造成磨損。如果驅(qū)動壓力高于要求值,會對進(jìn)氣閥造成嚴(yán)重的磨損而不得不提前更換進(jìn)氣閥。
在這種情況下,建議使用減壓閥或減壓閥站。減壓閥既可以允許將驅(qū)動壓力維持在能夠滿足泵排量的設(shè)定壓力,同時也可以保護(hù)進(jìn)氣閥不受磨損。另外,在應(yīng)用空間較狹窄時,建議使用帶集汽管的減壓閥站。在泵泵水過程中,集汽管為泵供汽從而為泵提供了緩沖區(qū)。這個緩沖區(qū)使整個裝置的動作柔和,減少對減壓閥的磨損。
DB和DBW類型閥是插裝結(jié)構(gòu)先導(dǎo)式溢流閥 ,它們用于限制系統(tǒng)壓力(DB)或限制和 電磁卸載(DBW只帶螺紋連接
)系統(tǒng)壓力。 該閥組主要包括閥體和溢流閥插裝元件。管路中的壓力作用于閥芯,并經(jīng)過節(jié)流孔同時作用于球
閥芯。當(dāng)管路中的壓力超過彈簧設(shè)定的壓力值時,球閥芯克服彈簧力開啟。此時來自油口的油液經(jīng)節(jié)流孔流入彈
簧腔,并通過控制通道由外部引回油箱。由于在閥芯高壓流體流動的平衡狀態(tài),油液經(jīng)A口流向B口,同時保持設(shè)
定的工作壓力不變。DBW 型溢流閥(僅螺紋連接型)原則上功能與DB型相同。借助頂裝方向閥可控制主閥卸荷。
