A4F016/32RNSC12定量泵故障排除基本要點(diǎn)
相對(duì)于定常系統(tǒng),大大節(jié)約了能量,達(dá) 15%盡管動(dòng)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(jì)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(shí)現(xiàn)流量的無級(jí)調(diào)節(jié)。工作噪音具有高功率密度驅(qū)動(dòng)適配器可互換,靈活性較高斜盤式設(shè)計(jì)軸向柱塞泵的作業(yè)原理,當(dāng)電動(dòng)機(jī)帶動(dòng)傳動(dòng)軸旋轉(zhuǎn)時(shí),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(diǎn),因而缸體旋轉(zhuǎn)時(shí),柱塞就在泵缸中做往復(fù)運(yùn)動(dòng)。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(shí),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(dòng)軸不斷旋轉(zhuǎn),泵便不斷地作業(yè)。"
用隔膜之前后動(dòng)作使隔膜與泵頭間變化造成球閥上下移動(dòng)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(shí),出口球閥掉下與球座緊緊密合,入口球閥因膜片后拉時(shí)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(shí),入口球閥與球座氣密,使液體不會(huì)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(dòng)作原理我們可簡單地知道膜片、泵頭、球閥球座任何一項(xiàng)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(xiàng)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(shí)之配管、配件及操作情形才可判定。

臥式柱塞泵是由幾個(gè)柱塞(一般為3個(gè)或6個(gè))并列安裝,用1根曲軸通過連桿滑塊或由偏心軸直接推動(dòng)柱塞做往復(fù)運(yùn)動(dòng),實(shí)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(dòng)活塞做往復(fù)運(yùn)動(dòng),實(shí)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(dòng)方向與缸體中心軸平行的柱塞泵。軸向柱塞泵利用與傳動(dòng)軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動(dòng)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(dòng)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(shí)就啟動(dòng)機(jī)器,會(huì)對(duì)液壓泵內(nèi)的滑靴造成拉脫現(xiàn)象,會(huì)造成泵體內(nèi)回程板與壓板的非正常磨損。
