能迅速恢復(fù)到減壓閥的閥后調(diào)定壓力值；反之，當(dāng)減壓閥閥前壓力時(shí)，卻會(huì)使減壓閥的閥后壓力瞬，但減壓閥將迅速調(diào)節(jié)，使閥后壓力升到調(diào)定值。如果減壓閥的閥前壓力的*值低于閥后壓力值，則閥后壓力就要相應(yīng)，而不能在調(diào)定壓力值上。所以，當(dāng)主油路執(zhí)行機(jī)構(gòu)的*工作壓力低于減壓闔的閥后壓力時(shí)，回路設(shè)計(jì)就應(yīng)采取必要措施，如在減壓閥的閥前增設(shè)單向閥，單向閥與減壓閥之間還可以增設(shè)蓄能器等措施，以防止減壓閥的閼前壓力低于閥后壓力。 高壓膠管出廠時(shí)，均經(jīng)過(guò)額定壓力1.25倍的耐壓試驗(yàn)。固定，可用鋼管代替。開(kāi)啟式電動(dòng)機(jī)內(nèi)部應(yīng)無(wú)雜物
