   A4F016/32RNSC12定量泵故障排除基本要點


 相對于定常系統(tǒng),大大節(jié)約了能量,達(dá) 15%盡管動力相同,卻減少了能耗,從而優(yōu)化了效率相比齒輪泵,壽命增長了集成式控制器,設(shè)計更緊湊的控制裝置具有很高的適應(yīng)性,可用于各種重要應(yīng)用通過調(diào)節(jié)旋轉(zhuǎn)斜盤角度,可實現(xiàn)流量的無級調(diào)節(jié)。工作噪音具有高功率密度驅(qū)動適配器可互換,靈活性較高斜盤式設(shè)計軸向柱塞泵的作業(yè)原理,當(dāng)電動機(jī)帶動傳動軸旋轉(zhuǎn)時,泵缸與柱塞一同旋轉(zhuǎn),柱塞頭永遠(yuǎn)保持與斜盤觸摸,因斜盤與缸體成一視點,因而缸體旋轉(zhuǎn)時,柱塞就在泵缸中做往復(fù)運(yùn)動。以一柱塞為例,它從0°轉(zhuǎn)到180°,即轉(zhuǎn)到上面柱塞的方位,柱塞缸容積逐漸增大,因而液體經(jīng)配油盤的吸油口a吸人油缸;而該柱塞從180°轉(zhuǎn)到360°時,柱塞缸容積逐漸減小,因而油缸內(nèi)液體經(jīng)配油盤的出口排出液體。只需傳動軸不斷旋轉(zhuǎn),泵便不斷地作業(yè)。" 

用隔膜之前后動作使隔膜與泵頭間變化造成球閥上下移動形成真空吸附與推擠現(xiàn)象達(dá)到液體輸送之目的。

①當(dāng)膜片往后拉時,出口球閥掉下與球座緊緊密合,入口球閥因膜片后拉時與泵頭間產(chǎn)生真空而往上浮起,液體跟著被吸上來。

②當(dāng)膜片往前推時,入口球閥與球座氣密,使液體不會通過,而出口因膜片往前推擠使球閥開啟,液體吐出


由以上之動作原理我們可簡單地知道膜片、泵頭、球閥球座任何一項因素造成漏氣則無法達(dá)到輸送之目的,或流量異常,通常由此四項組成主生之故障為:

① 球座與球閥無法氣密

② 入口、出口異物阻塞

③ 膜片破損

故若液體輸送異常,朝這方面處理,應(yīng)該都可解決,而造成上述情況之因素為何,不勝枚舉,端視當(dāng)時之配管、配件及操作情形才可判定。

臥式柱塞泵是由幾個柱塞(一般為3個或6個)并列安裝,用1根曲軸通過連桿滑塊或由偏心軸直接推動柱塞做往復(fù)運(yùn)動,實現(xiàn)吸、排液體的液壓泵。它們也都采用閥式配流裝置,而且大多為定量泵。煤礦液壓支架系統(tǒng)中的乳化液泵一般都是臥式柱塞泵。乳化液泵用于采煤工作面,為液壓支架提供乳化液,工作原理靠曲軸的旋轉(zhuǎn)帶動活塞做往復(fù)運(yùn)動,實現(xiàn)吸液和排液。軸向式軸向柱塞泵(英文名:Piston pump)是活塞或柱塞的往復(fù)運(yùn)動方向與缸體中心軸平行的柱塞泵。軸向柱塞泵利用與傳動軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動所產(chǎn)生的容積變化來進(jìn)行工作的。由于柱塞和柱塞孔都是圓形零件,可以達(dá)到很高的精度配合,因此容積效率高。直軸斜盤式直軸斜盤式柱塞泵分為壓力供油型和自吸油型兩種。壓力供油型液壓泵大都是采用有氣壓的油箱,靠氣壓供油的液壓油箱,在每次啟動機(jī)器之后,必須等液壓油箱達(dá)到使用氣壓后,才能操作機(jī)械。如果液壓油箱的氣壓不足時就啟動機(jī)器,會對液壓泵內(nèi)的滑靴造成拉脫現(xiàn)象,會造成泵體內(nèi)回程板與壓板的非正常磨損。
