液控單向閥沖擊振動(dòng)噪聲的産生與解決
液控單向閥在液壓缸液壓回路中應(yīng)用十分廣泛提醒大家在應(yīng)用此閥時(shí),必須充分考慮該閥的特點(diǎn),否則會(huì)造成回路不穩(wěn)定,尤其是在高壓液壓系統(tǒng)中,液控單向閥反向開啓前P2口的壓力很高,爲(wèi)了減小液壓系統(tǒng)中的控制壓力,液壓沖擊和噪聲,采用了卸荷閥芯的液壓控單向閥,卸荷閥能使液控單向閥性能得到改善,該液控單向閥的特點(diǎn)是,當(dāng)液控單向閥口K處于無(wú)壓力油時(shí),壓力油隻能從油口P1流向油口P2,不能反向。當(dāng)控制口K有控制壓力油時(shí),油液因控制活塞推動(dòng)頂桿,而頂桿頂開卸荷閥芯,同時(shí)主閥芯打開,接通P1、P2兩通口,油液可在這兩個(gè)方向上自由流通,卸荷閥減小了液壓沖擊,使液壓缸液控單向閥的性能較穩(wěn)定,但在大流量高壓系統(tǒng)中仍存在沖擊或噪聲。
液控單向閥常應(yīng)用在保壓,洩壓,鎖緊回路中。由于液壓系統(tǒng)保壓過(guò)程中,因壓力大,油液壓縮、管道膨脹,元件發(fā)生彈性變形等都能貯存能量,在洩壓時(shí),能量突然釋放,并且在換向閥從中位到左位時(shí),由于液壓缸上腔壓力較大,此時(shí)下腔壓力已升高,卸荷閥與主閥幾乎同時(shí)打開,使上腔的壓力油突然通過(guò)液控單向閥釋放到回油路。由于這兩個(gè)原因同時(shí)存在而使保壓后洩壓太快,産生沖擊振動(dòng)和噪聲,因此 大蘭液壓廠家對(duì)該類液壓回路增加一節(jié)流閥得以解決。
由于高壓大流量液控單向閥導(dǎo)緻了洩壓過(guò)快,使沖擊增大,于是在該回路中加上一節(jié)流閥,從而使液控單向閥卸荷閥先打開,然后再打開主閥,由于節(jié)流閥具有足夠的流量控制范圍,能保證穩(wěn)定的最小流量,調(diào)節(jié)方便,洩漏小,溫度和壓力對(duì)影響也小,所以通過(guò)調(diào)節(jié)節(jié)流閥,控制液壓缸上腔的油液洩壓時(shí)間也相應(yīng)延長(zhǎng),洩壓能力也會(huì)增強(qiáng),同時(shí)還減少了液壓油對(duì)各元件的沖擊及噪聲。
