力士樂液壓泵以其結(jié)構(gòu)簡單、使用維修方便、效率較高而成為農(nóng)業(yè)上應(yīng)用zui廣泛一種水泵,但也因提不上水而令人倍感煩惱。現(xiàn)就提不上水這一。
力士樂液壓泵故意障原因加以分析
1)力士樂液壓泵有些用戶水泵啟動前未灌滿足夠水;看上去灌水已從放氣孔溢出,但未轉(zhuǎn)動泵軸交空氣*排出,致使少許空氣還殘留進(jìn)水管或泵體中。
2)力士樂液壓泵接觸進(jìn)水管水平段逆水流方向應(yīng)用0.5%以上下降坡度,連接水泵進(jìn)口一端為zui高,不要*水平。向上翹起,進(jìn)水管內(nèi)會存留空氣,降低了水管和水泵中真空度,影響吸水。
3)REXROTH葉片泵填料因長期使用已經(jīng)磨損或填料壓過松,造成大量水從填料與泵軸軸套間隙中噴出,其結(jié)果是外部空氣就從這些間隙進(jìn)入水泵內(nèi)部,影響了提水。
4)進(jìn)水管因長期潛水下,管壁腐蝕出現(xiàn)孔洞,水泵工作后水面不斷下降,當(dāng)這些孔洞露出水面后,空氣就從孔進(jìn)入了進(jìn)水管。
5)進(jìn)水管彎管處出現(xiàn)裂痕,進(jìn)水管與水泵連接處出現(xiàn)微小間隙,都有可能使空氣進(jìn)入進(jìn)水管。 水泵轉(zhuǎn)速過低
1)人為因素。有相當(dāng)一部分用戶因原配電動機(jī)損壞,就隨意配上另一臺電動機(jī)帶動,結(jié)果造成了流量少、揚程低抽不上水后果。
2)傳動帶磨損。有許多大型離水泵采用帶傳,因長期使用,傳動帶磨損而松也,出現(xiàn)打滑現(xiàn)象,降低了水泵轉(zhuǎn)速。
3)安裝不當(dāng)。兩帶輪中心距太小或兩軸不太平行,傳動帶緊邊安裝到上面,致使包角太小,兩帶輪直徑計
算差錯以及聯(lián)軸傳動水泵兩軸偏心距較大等,均會造成水泵轉(zhuǎn)速變化。
4)REXROTH葉片泵本身機(jī)械故障。葉輪與泵軸緊固螺母松脫或泵軸變形彎曲,造成葉輪多移,直接與泵體摩擦,或軸承損壞,都有可能降低水泵轉(zhuǎn)速。
5)動力機(jī)維修不錄。電動機(jī)因繞組燒毀,而失磁,維修中繞組匝數(shù)、線徑、接線方法改變,或維修中故障未*排除因素也會使水泵轉(zhuǎn)速改變。
6)吸程太大。有些水源較深,有些水源外圍勢較平坦處,而忽略了水泵容許吸程,產(chǎn)生了吸水少或根本吸不上水結(jié)果。要知道水泵吸水口處能建立真空度是有限度,真空時吸程約為10米水柱高,而水泵不可能建立真空。真空度過大,易使泵內(nèi)水氣化,對水泵工作不利。各離心泵都有其zui大容許吸程,一般3~8.5米之間,安裝水泵時切不可只圖方便簡單。
REXROTH葉片泵因其有可變量輸送、自吸能力強、可逆轉(zhuǎn)、能輸送含固體顆粒的液體等特點,在污水處理廠中,廣泛地被使用在輸送水、濕污泥和絮凝劑藥液方面。螺桿泵選用應(yīng)遵循經(jīng)濟(jì)、合理、可靠的原則。如果在設(shè)計選型方面考慮不周,會給以后的使用、管理、維修帶來麻煩,所以選用一臺按生產(chǎn)實際需要,合理可靠的螺桿泵既能保證生產(chǎn)順利進(jìn)行,又可降低修理成本。
