溢流閥壞了的判斷方法

2019-09-06

  1、壓力大無法自動溢流,會造成動作異常,打齒。
  2、溢流閥自動溢流,不保壓會造成無動作?!∫缌鏖y的工作原理及作用;
  1、溢流閥定壓溢流作用:在定量泵節流調節系統中,定量泵提供的是恒定流量。當系統壓力增大時,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)。
  2、安全保護作用:系統正常工作時,閥門關閉。只有負載超過規定的極限(系統壓力超過調定壓力)時開啟溢流,進行過載保護,使系統壓力不再增加(通常使溢流閥的調定壓力比系統極限工作壓力高10%~20%)。噴油嘴廠家
  3、作卸荷閥用作遠程調壓閥:
  作高低壓多級控制閥作順序閥用于產生背壓(串在回油路上)。
  先導型溢流閥由主閥和先導閥兩部分組成。先導閥類似于直動型溢流閥,但一般多為錐閥(或球閥)形閥座式結構。主閥可分為一節同心結構、二節同心結構和三節同心結構。
