REXROTH葉片泵安裝不當(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(jì)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。 力士樂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。 REXROTH葉片泵電動機(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。 REXROTH葉片泵工作前,先將泵內(nèi)充滿液體,然后啟動離心泵,葉輪快速轉(zhuǎn)動,葉輪的葉片驅(qū)使液體轉(zhuǎn)動,液體轉(zhuǎn)動時(shí)依靠慣性向葉輪外緣流去,同時(shí)葉輪從吸入室吸進(jìn)液體。上海維特銳供應(yīng)力士樂葉片泵 在這一過程中,力士樂葉片泵的葉輪中的液體繞流葉片,在繞流運(yùn)動中液體作用一升力于葉片,反過來葉片以一個與此升力大小相等、方向相反的力作用于液體,這個力對液體做功,使液體得到能量而流出葉輪,這時(shí)液體 的動能與壓能均增大。 上海維特銳可提供力士樂報(bào)關(guān)單等證明,在德國設(shè)立的分公司,有能力持續(xù)穩(wěn)定供應(yīng)力士樂產(chǎn)品 R900563233 PV7-1X/06-10RA01MA0-10 R900560659 PV7-1X/63-94RE07MC0-08 R900535588 PV7-1X/40-71RE37MC0-08 R900534143 PV7-1X/10-20RE01MC0-10 R900533582 PV7-1X/16-30RE01MC0-08 R900506809 PV7-1X/100-118RE07MC0-16 R900506808 PV7-1X/63-71RE07MC0-16 R900504653 PV7-1X/10-14RE01MD0-16 513800437 0513R15A7V PV72SM21JSB05PVV2-1X/040RA15DMB PVV2-1X/045RA15DMB PVV2-1X/055RA15DMB PVV2-1X/060RA15DMB PVV2-1X/068RA15DMB PVV4-1X/069RA15DMB PVV4-1X/082RA15DMB PVV4-1X/098RA15DMB PVV4-1X/113RA15DMB PVV4-1X/122RA15DMB PVV5-1X/139RA15DMB PVV5-1X/154RA15DMB PVV5-1X/162RA15DMB PVV5-1X/183RA15DMB PVV5-1X/193RA15DMB PVV5-1X/193RA15DMB PVV21-1X/060-040RA15DDMB PVV21-1X/068-027RA15LUMB PVV41-1X/098-027RA15UDMC PVV41-1X/122-036RA15DDMC PVV42-1X/098-045RA15DDMC PVV21-1X/068-027RA15LUMB PVV51-1X/162-036RB15DDMC PVV51-1X/193-027RA15DDMC PVV52-1X/193-040RB15URMC PVV52-1X/193-055RB15UUMC PVV54-1X/183-082RA15DDMC PVV54-1X/139-082RA15UUMC PVV52-1X/139-068RA15DLMC PVV5-1X/193RA15LMC PVV54-1X/139-069RA15UUMC PVV2-1X/068RJ15UMB PVV4-1X/113RJ15UMC PVV1-1X/027LA15LMB PVV42-1X/082-045RA15DDMC PVV1-1X/027RJ15DVB PVV54-1X/162-082RB15UUMC PVV41-1X/082-018RA15RRVC PVV41-1X/082-046RA15UUMC PVV51-1X/139-027RA15DLMC PVV52-1X/139-068RA15DLMC PVV21-1X/040-018RB15UDMB PVV5-1X/154RJ15DVC PVV21-1X/055-018RA15UUVB PVV5-1X/193RA15LMC PVV4-1X/122RA15RMC PVV54-1X/154-113RJ15UUMC PVV21-1X/045-027RJ15UUMB PVV21-1X/068-027RA15URMB PVV51-1X/154-027RA15RRVC PVV54-1X/193-122RA15UUVC PVV54-1X/193-113RA15UUVC PVV1-1X/046RA15DVB PVV41-1X/082-036RA15LLMC PVV2-1X/060RA15LMB PVV54-1X/193-082RA15DDMC PVV52-1X/154-055RA15UUMC PVV42-1X/082-068RA15UUMC |
