產(chǎn)品詳情
對(duì)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(dòng)作靈敏,過(guò)載能力大,噪聲小。
1)電磁溢流閥原理上,一般是由先導(dǎo)式溢流閥加上一個(gè)2位2通電磁閥組成。
2)這個(gè)電磁閥實(shí)際上由兩部分組成:2位2通的液壓閥部分,加上一個(gè)電磁鐵。2位2通閥是開(kāi)通,還是關(guān)閉,是由電磁鐵推動(dòng)閥芯運(yùn)動(dòng)來(lái)實(shí)現(xiàn)的。像樓上朋友講的,有的閥電磁鐵通電時(shí)打開(kāi),有的閥電磁鐵斷電時(shí)打開(kāi),蘿目青菜個(gè)人各愛(ài)(根據(jù)系統(tǒng)要求選擇)。也就是說(shuō),電磁閥這里有一條通路一頭與先導(dǎo)溢流閥的某個(gè)部位相連,另一頭通過(guò)油管與油箱相連。通過(guò)操作電磁鐵可以讓先導(dǎo)溢流閥的某個(gè)部位或者與油箱相通,或者不與油箱相通。
3)先導(dǎo)溢流閥的主閥上腔壓力,是由先導(dǎo)閥加于控制的。如果先導(dǎo)閥正常工作,即主閥上腔有先導(dǎo)閥規(guī)定的壓力,則整個(gè)溢流閥就會(huì)在系統(tǒng)壓力到達(dá)調(diào)定壓力時(shí)其主閥口打開(kāi)一定的開(kāi)度,一方面能將系統(tǒng)多余流量流回油箱,另一方面又能維持系統(tǒng)的壓力為先導(dǎo)閥的調(diào)定值。可見(jiàn),先導(dǎo)閥主要管壓力,主閥服從先導(dǎo)閥的領(lǐng)導(dǎo),在先導(dǎo)閥動(dòng)作時(shí)將主閥口開(kāi)到合適大小,正好將多余流量流出去,又不影響系統(tǒng)壓力。
4)如果先導(dǎo)閥不調(diào)什么壓力,也就是說(shuō)主閥上腔沒(méi)有先導(dǎo)閥控制的壓力,這樣主閥芯就解放了,由于沒(méi)有來(lái)自上腔調(diào)壓力,閥口就開(kāi)到最da,油源來(lái)的油不再進(jìn)入系統(tǒng)而以盡可能低的卸荷壓力流回油箱。
5)可見(jiàn)定差溢流閥中的電磁閥,僅僅在系統(tǒng)卸荷時(shí)(液壓閥部分)流過(guò)1-2升/分的先導(dǎo)流量,而浩浩蕩蕩的主流量還是通過(guò)主閥口流回油箱020127 WS08W-01M-C-N-12DL
