力士乐Rexroth柱塞泵1.泵的轴线与电机的轴线虚保持一定的同轴度。对于齿轮泵,泵的转动轴与电机输出轴之间的安装采用弹性联轴节,其不同轴度不得大于O.1mm,采用轴套式联轴节的不同轴度不得大于0.05mm;对于叶片泵,一般要求不同轴度不得大于0.1mm,且与电机之间应采用挠性连接;同样对于斜盘式轴向安装精度也提出具体要求:(1)支座安装的斜盘式轴向泵,其同轴度检查允差事=0.1mm;(2)采用法兰安装时,安装精度要求其芯轴径向法兰同轴度检查公差为西=0.1mm:法兰垂直度检查允差t=0.1mm;(3)采用轴承支架安装皮带轮或齿轮,然后通过弹性联轴节与泵联接,来保证泵的主动轴不承受径向力和轴向力。可以允许承受的力应严格控制在许用范围内,特殊情况下还要对转子进行精密的动平衡实验,以尽量避免共振。2.滤器的安装为避免泵抽空,严禁使用精密过滤器。对于齿轮泵的过滤精度应≤40um,在吸油口常用网式过滤器。对于叶片泵,柱塞泵,油液的清洁度应达到国家标准等级16/19级,使用的过滤器精度大多为25~30um。吸油口过滤器的正确选择和安装,会使液压故障明显减少,各元件的使用寿命可大大延长。REXROTH柱塞泵系列型号有:A4VSO系列,A10VSO系列,A4VG系列,A4V系列,A6VM系列,A7VO系列,A8VO系列,A2FO系列士乐(REXROTH)液压泵及液压马达1.A8VO系列:A8VO55,A8VO80,A8VO107,A8VO1602.A2F系列:A2F23,A2F28,A2F55,A2F80,A2F107,A2F1603.A4VSO系列:A4VSO40,A4VSO45,A4VSO56,A4VSO71,A4VSO125,A4VSO180,A4VSO250,A4VSO3554.A4VG系列:A4VG28,A4VG45,A4VG50,A4VG56,A4VG71,A4VG125,A4VG180,A4VG2505.A6V系列:A6V55,A6V80,A6V107,A6V160,A6V225,A6V2506.A7V系列:A7V16,A7V28,A7V55,A7V80,A7V107,A7V160,A7V200,A7V2507.A8V系列:A8V55,A8V80,A8V107,A8V115,A8V1728,A10VSO系列:A10VSO28.A10VSO43,A10VSO45,A10VSO71,A10VSO100,A10VSO1409.A10VD系列:A10VD17,A10VD21,A10VD28,A10VD43,A10VD7110.A11V系列:A11V130,A11V160,A11V190,A11V250A10VSO45DFR1/31R-PPA12N00(R910907403),A10VSO45DFR1/31R-PPA12N00(R902427886),A10VSO45DR/31R-PPA12N00(R910908725),A10VSO71DFR1/32R-VPB22U99S2183(R902449039),A10VSO18DFR1/31R-PPA12N00(R910945178),A10VSO18DFR1/31R-PPA12N00(R910945178),A10VSO28DFR1/31R-PPA12N00(R902449017),A10VSO28DFR1/31R-PPA12N00(R910903163),A10VSO28DFR1/31R-PPA12N00(R910910590),A10VSO37DFR1/31R-PPA12N00(R910905405),A10VSO71DFR1/32R-VPB22U99(R902449040),A10VSO71DFR1/32R-VPA12N00(R902427855),A10VSO71DRS/32R-VPB22U999(R902452429),A10VSO71DFR1/31R-PPA1200-S1486(R902427947),A10VSO100DRS/32R-VPB1200-S1439(R902436353)。A10VSO45(37)DFR1/31R-PPA12N00-S1648(R902428405),A10VSO71DFR1/31R-PPA12N00-S16458CORE(58CC)(R902427855),
