如何選擇液壓系統(tǒng)控制閥額定壓力
液壓閥的額定壓力如何選擇呢?根據(jù)液壓系統(tǒng)設(shè)計(jì)的工作壓力選擇相應(yīng)壓力級(jí)的液壓閥,并且使系統(tǒng)的工作壓力適當(dāng)?shù)陀诋b品標(biāo)明的額定壓力值。
對(duì)于高壓系列的液壓閥,一般都能適用于該額定壓力以下的所有工作壓力范圍。對(duì)液壓閥流量參數(shù)的選擇可以根據(jù)産品標(biāo)明的公稱流量爲(wèi)依據(jù)。如果産品能提供通過不同流量時(shí)的有關(guān)性能曲線,則對(duì)元件的選擇使用就更爲(wèi)合理了,一個(gè)液壓系統(tǒng)各部分回路通過的流量不可能都相同。因此不能單純根據(jù)液壓泵的額定輸出流量來選
如換向閥的選擇則要考慮到如果液壓系統(tǒng)中采用差動(dòng)液壓缸,在液壓缸換向動(dòng)作時(shí),無桿腔排出的流量比有桿腔排出流量大許多,甚至可能比液壓泵輸出的最大流量還要大;再如果選擇節(jié)流閥、調(diào)速閥時(shí),不僅要考慮可能通過該閥的最大流量,還應(yīng)考慮到該閥的最小穩(wěn)定流量指標(biāo);又如某些回路通過的流量比較大,如果選擇與該流量相當(dāng)?shù)?換向閥,在換向動(dòng)作時(shí)可能産生較大的壓力沖擊,爲(wèi)了改善系統(tǒng)工作性能,可選擇大一檔規(guī)格的換向閥;某些系統(tǒng)大部分工作狀態(tài)通過的流量不大,偶然會(huì)有大流量通過,考慮到系統(tǒng)布置的緊湊,以及閥本身工作性能的允許,或者壓力損失的瞬時(shí)增加,在許可的情況下,仍按大部分工作狀況的流量規(guī)格選取,允許液壓閥在短時(shí)超流量狀態(tài)下使用。
