力士樂REXROTH溢流閥ZDB系列 一、力士樂溢流閥的功能: REXROTH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(shí),會(huì)使流量需求減小。此時(shí)溢流閥開啟,使多余流量溢回油箱,保證溢流閥進(jìn)口壓力,即泵出口壓力恒定(閥口常隨壓力波動(dòng)開啟)。 力士樂安全保護(hù)作用:系統(tǒng)正常a工作時(shí),閥門關(guān)閉。只有負(fù)載超過規(guī)定的極限(系統(tǒng)壓力超過調(diào)定壓力)時(shí)開啟溢流,進(jìn)行過載保護(hù),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)zui高工作壓力高10%~20%)。 1、作卸荷閥用 ; 2、作遠(yuǎn)程調(diào)壓閥; 3、作高低壓多級(jí)控制閥; 4、作順序閥; 5、用于產(chǎn)生背壓(串在回油路上)。 力士樂REXROTH溢流閥ZDB系列 ZDR6DP2-4X/150YM ZDR10DP2-5X/210YM ZDR6DP2-4X/210YM ZDR6DP2-4X/75YM ZDR10DP2-5X/150YM ZDB6GVB2-4X ZDB6GVB2-4X/200V ZDB6VA1-4X/200V ZDB10VA1-4X/200V ZDB10VA1 ZDB10VA1-4X/200V ZDB10VP2-41/200V ZDB10VC2-4X/200V ZDB10VB2-4X/200V ZDB10VP2-41/200V ZDB10VA1-4X/200V ZDB10VA1-4X/200V -
