【Z2DB16VD2-2X/100V先導(dǎo)式溢流閥】詳細說明
?Z2DB16VD2-2X/100V先導(dǎo)式溢流閥力士樂電磁溢流閥
溢流閥是一種液壓壓力控制閥。在液壓設(shè)備中主要起定壓溢流作用,穩(wěn)壓,系統(tǒng)卸荷和安全保護作用。  定壓溢流作用:在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中,定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力增大時,會使流量需求減小。此時溢流閥開啟,使多余流量溢回油箱,保證溢流閥進口壓力,即泵出口壓力恒定(閥口常隨壓力波動開啟)。
穩(wěn)壓作用:溢流閥串聯(lián)在回油路上,溢流閥產(chǎn)生背壓運動部件平穩(wěn)性增加。   
系統(tǒng)卸荷作用:在溢流閥的遙控口串接溢小流量的電磁閥,當(dāng)電磁鐵通電時,溢流閥的遙控口通油箱,此時液壓泵卸荷。溢流閥此時作為卸荷閥使用。   
安全保護作用:系統(tǒng)正常工作時,閥門關(guān)閉。只有負載超過規(guī)定的極限(系統(tǒng)壓力超過調(diào)定壓力)時開啟溢流,進行過載保護,使系統(tǒng)壓力不再增加(通常使溢流閥的調(diào)定壓力比系統(tǒng)最高工作壓力高10%~20%)。   
實際應(yīng)用中一般有:作卸荷閥用,作遠程調(diào)壓閥,作高低壓多級控制閥,作順序閥,用于產(chǎn)生背壓(串在回油路上)。   
溢流閥一般有兩種結(jié)構(gòu):1,直動型溢流閥 。2,先導(dǎo)型溢流閥。   
對溢流閥的主要要求:調(diào)壓范圍大,調(diào)壓偏差小,壓力振擺小,動作靈敏,過載能力大,噪聲小。
比例閥采用閥芯 閥體結(jié)構(gòu)。伺服閥和伺服比例閥主要應(yīng)用在閉環(huán)控制系統(tǒng),比例閥的驅(qū)動裝置是比例電磁鐵。
伺服閥的驅(qū)動裝置是力馬達或力矩馬達.閥體兼作閥套。
驅(qū)動裝置不同.所以近些年出現(xiàn)了比例伺服閥。
比例閥一般最高幾十Hz,伺服閥中位沒有死區(qū),伺服閥對液壓油液的要求更高.性能參數(shù)不同;否則容易堵塞,
用來控制流量和流向,比例閥要求低一些.比例閥有中位死區(qū);
比例閥和伺服閥的區(qū)別主要體現(xiàn)在以下幾點:
逐漸向伺服閥靠近,
比例換向閥屬于比例閥的一種,滯環(huán),中位死區(qū),頻寬,過濾精度等特性不同.閥的額定壓降不同;比例換向閥具有與普通換向閥相似的中位機能,
而比例伺服閥性能介于伺服閥和比例閥之間,因此應(yīng)用場合不同,伺服閥和伺服比例閥采用閥芯 閥套的結(jié)構(gòu)。中位機能種類不同.其它結(jié)構(gòu)的比例閥主要應(yīng)用在開環(huán)控系統(tǒng)及閉環(huán)速度控制系統(tǒng);因為比例閥的性能越來越好;2伺服閥的頻響(響應(yīng)頻率)更高。閥芯結(jié)構(gòu)及加工精度不同.伺服閥與比例閥之間的差別并沒有嚴格的規(guī)定。
,可以高達200Hz左右,需要精過濾才行,而伺服閥中位機能只有O型(Rexroth產(chǎn)品的E型)。武穴黎翔專業(yè)代理德國力士樂全系列產(chǎn)品, 專注原裝全新力士樂 ,假一罰萬,力士樂好價格??!歡迎詢價?。?/span>
