REXROTH泵A10V0系列應(yīng)用領(lǐng)域
REXROTH泵選型依據(jù),應(yīng)根據(jù)工藝流程,給排水要求,從五個(gè)方面加以考慮,既液體輸送量、裝置揚(yáng)程、液體性質(zhì)、管路布置以及操作運(yùn)轉(zhuǎn)條件等。
1.REXROTH泵流量是選泵的重要性能數(shù)據(jù)之一,它直接關(guān)系到整個(gè)裝置的的生產(chǎn)能力和輸送能力。如設(shè)計(jì)院工藝設(shè)計(jì)中能算出泵正常、zui小、zui大三種流量。選擇泵時(shí),以zui大流量為依據(jù),兼顧正常流量,在沒有zui大流量時(shí),通??扇≌A髁康?.1倍作為zui大流量。
2.REXROTH泵裝置系統(tǒng)所需的揚(yáng)程是選泵的又一重要性能數(shù)據(jù),一般要用放大5%—10%余量后揚(yáng)程來選型。
3.REXROTH泵液體性質(zhì),包括液體介質(zhì)名稱,物理性質(zhì),化學(xué)性質(zhì)和其它性質(zhì),物理性質(zhì)有溫度c密度d,粘度u,介質(zhì)中固體顆粒直徑和氣體的含量等,這涉及到系統(tǒng)的揚(yáng)程,有效氣蝕余量計(jì)算和合適泵的類型:化學(xué)性質(zhì),主要指液體介質(zhì)的化學(xué)腐蝕性和毒性,是選用泵材料和選用那一種軸封型式的重要依據(jù)。
4. REXROTH泵裝置系統(tǒng)的管路布置條件指的是送液高度送液距離送液走向,吸如側(cè)zui低液面,排出側(cè)zui高液面等一些數(shù)據(jù)和管道規(guī)格及其長度、材料、管件規(guī)格、數(shù)量等,以便進(jìn)行系統(tǒng)揚(yáng)程計(jì)算和汽蝕余量的校核。
5. REXROTH泵操作條件的內(nèi)容很多,如液體的操作T飽和蒸汽力P、吸入側(cè)壓力PS()、排出側(cè)容器壓力PZ、海拔高度、環(huán)境溫度操作是間隙的還是連續(xù)的、泵的位置是固定的還是可移的。
REXROTH泵是采用磁懸浮原理和螺旋環(huán)流體力學(xué)結(jié)構(gòu)實(shí)現(xiàn)流質(zhì)推進(jìn),REXROTH泵即取消軸,取消軸連接,取消軸密封結(jié)構(gòu)。啟動(dòng)后電流轉(zhuǎn)化為磁場,磁場力驅(qū)動(dòng)螺旋環(huán)運(yùn)轉(zhuǎn),即螺旋環(huán)提升流質(zhì)前進(jìn)。
REXROTH泵選型原則
1.REXROTH泵使所選泵的型式和性能符合裝置流量、揚(yáng)程、壓力、溫度、汽蝕流量吸程等工藝參數(shù)的要求。
2.REXROTH泵必須滿足介質(zhì)特性的要求。
對(duì)輸送易燃、易爆有毒或貴重介質(zhì)的泵,要求軸封可靠或采用無泄漏泵,如磁力驅(qū)動(dòng)泵、隔膜泵、屏蔽泵
對(duì)輸送腐蝕性介質(zhì)的泵,要求對(duì)流部件采用耐腐蝕性材料。
對(duì)輸送含固體顆粒介質(zhì)的泵,要求對(duì)流部件采用耐磨材料,必要時(shí)軸封用采用清潔液體沖洗。
3.REXROTH泵機(jī)械方面可靠性高、噪聲低、振動(dòng)小。
4.REXROTH泵經(jīng)濟(jì)上要綜合考慮到設(shè)備費(fèi)、運(yùn)轉(zhuǎn)費(fèi)、維修費(fèi)和管理費(fèi)的總成本zui低。
5.REXROTH泵具有轉(zhuǎn)速高、體積小、重量輕、效率高、流量大、結(jié)構(gòu)簡單、輸液無脈動(dòng)、性能平穩(wěn)、容易操作和維修方便等特點(diǎn)。
REXROTH泵A10V0系列應(yīng)用領(lǐng)域REXROTH泵殼內(nèi),并緊固在泵軸上,泵軸由電機(jī)直接帶動(dòng)。泵殼中央有液體吸管。液體經(jīng)底閥和吸入管進(jìn)入泵內(nèi)。泵殼上的液體排出口與排出管連接。
在泵啟動(dòng)前,泵殼內(nèi)灌滿被輸送的液體;啟動(dòng)后,葉輪由軸帶動(dòng)高速轉(zhuǎn)動(dòng),葉片間的液體也必須隨著轉(zhuǎn)動(dòng)。在離心力的作用下,液體從葉輪中心被拋向外緣并獲得能量,以高速離開葉輪外緣進(jìn)入蝸形泵殼。在蝸殼中,液體由于流道的逐漸擴(kuò)大而減速,又將部分動(dòng)能轉(zhuǎn)變?yōu)殪o壓能,REXROTH泵zui后以較高的壓力流入排出管道,送至需要場所。液體由葉輪中心流向外緣時(shí),在葉輪中心形成了一定的真空,由于貯槽液面上方的壓力大于泵入口處的壓力,液體便被連續(xù)壓入葉輪中。可見,只要葉輪不斷地轉(zhuǎn)動(dòng),液體便會(huì)不斷地被吸入和排出。
直線泵工作原理不同與其它任何泵。
