賀德克(ke)過濾器是輸送介質(zhi)管道上*的一(yi)種裝置，通常安裝在減(jian)壓(ya)閥(fa)、泄(xie)壓(ya)閥(fa)、定水位閥(fa) ,方(fang)工過濾器其它設備的進口端設

過濾(lv)(lv)器按獲(huo)得過濾(lv)(lv)推動(dong)力的方法(fa)不同，分為重力過濾(lv)(lv)器、真空過濾(lv)(lv)器和加(jia)壓過濾(lv)(lv)器三類。

重力(li)

借助懸(xuan)浮液的重(zhong)力和位差在(zai)過(guo)濾介質上形成(cheng)的壓力作為過(guo)濾的推動(dong)力，一般為間歇操作，如砂器。

選(xuan)型(xing)要點

選用濾(lv)油器時，要考慮下列幾點：

⑴過濾精度(du)應滿足預定要求。

⑵能在較長時間內保持足(zu)夠的通流能力。

⑶濾芯具有足夠的(de)強度，不因液壓的(de)作用而(er)損(sun)壞。

⑷濾芯抗腐蝕性(xing)能好(hao)，能在規定(ding)的溫度下持久地(di)工作(zuo)。

⑸濾芯清(qing)洗或更換簡便(bian)。

因此，濾油器應根據液壓系統的技術要求，按過濾精度、通流能力、工作壓力、油液粘度、工作溫度等條件選定其型號。以下(xia)為賀德克(ke)過濾器部分型號(hao)展示：
