威格士柱塞泵工作原理威格士柱塞泵是往复泵的一种，属于体积泵，其柱塞靠泵轴的偏心转动驱动，往复运动，其吸入和排出阀都是单向阀。当柱塞外拉时，工作室内压力降低，出口阀关闭，低于进口压力时，进口阀打开，液体进入;柱塞内推时，工作室压力升高，进口阀关闭，高于出口压力时，出口阀打开，液体排出。带滑靴结构的轴向柱塞泵是目前使用最广泛的轴向柱塞泵，安放在缸体中的柱塞通过滑靴与斜盘相接触，当传动轴带动缸体旋转时，斜盘将柱塞从缸体中拉出或推回，完成吸排油过程。柱塞与缸孔组成的工作容腔中的油液通过配油盘分别与泵的吸、排油腔相通。变量机构用来改变斜盘的倾角，通过调节斜盘的倾角可改变泵的排量。20V-5A-1C-22R20V-5A-1D-22R20V-8A-1A-22R20V-8A-1C-22L20V-11A-1A-22R20V-11A-1C-22L20V-12A-1A-22R20V-14A-1D-22R20VQ-5A-1C-3025V-10A-1A-22R25V-10A-1C-22L25V-10A-86C-22R25V12A-1B-22R25V12A-1C-22R25V12A1D-22R25V12A-11A-22R25V14A-1A-22R25V14A-1B-22R25V14A-1C-22R25V14A-1D-22R25V14A-1B-22L25V14AF-1C-22R25V14AM-1D-22R25V17A-1A-22R25V17A-1B-22R25V17A-1C-22R25V17A-1D-22R25V17A-1A-22L25V17A-11B-22L25V21A-1A-22R25V21A-1B-22R25V21A-1C-22R25V21A-1D-22R25V21A-1A-22L35V25A-1A-22R35V25A-1B-22R35V25A-1C-22R35V25A-1D-22R35V30A-1A-22R35V30A-1B-22R35V30A-1C-22R2520V17A5-1AA-22R2520V17A51BB22L2520V17A51CC22R2520V17A51DD22R2520V17A51AB22R2520V17A81AA22R2520V17A81CC22R2520V17A81CC22L2520V17A81CB22R2520V17A1186DD22R2520V17A111DD22R2520V17A141AA22R2520V17A141CC22R2520V17A141CB22R2520V21A21AA22R2520V21A21CC22R2520V21A51AA22R2520V21A51CC22R2520V21A51DD22R2520V21A81AA22R2520V21A81BB22R2520V21A81CC22R2520V21A81DD22R2520V21A111AA22R2520V21A111CC22R2520V21A11-1AB22R2520V21A11-1DA22R2520V21A121AA22R2520V21A121BB22R2520V21A121CC22R2520V21A121DD22R2520V21A121CB22R2520V21A141AA22R2520V21A141DD22R2520V21A14-1AB22R2520V21A141AC22R2520V21A141AD22R2520V21A141CB22R2520VQH17A12-1DD20R2525V21A1786DA22R3520V25A51AA22R3520V25A51CC22R3520V25A8-86CB22R3520V25A111BB22R3520V25A1186AB22R3520V25A121AA22R3520V25A121CC22R3520V25A12-1DD22R3520V30A21CC22R3520V30A51DB22R3520V30A51DC22R3525V35A21-1BA22R3525V38A12-1BB-22R3525V38A1411AA22R3525V38A171AA22R3525V38A171BB22R3525V38A171CC22R3525V38A171BA22R3525V38A171DA22R3525V38A211AA22R3525V38A21-1BB22R3525V38A21-1CC22R3525V38A21-1AB22R3525V38A21-86BB22R3525V38A21-86CC22R3525VQ30A21-1DD204520V42A5-1CC22R4520V42A11-1AB22R4520V42A11-1AC22R4520V42A12-1CC22R4520V42A12-86DD22R4520V50A5-1CC22R4520V50A8-1CC22R4520V50A11-1AA22R4520V50A11-1CC22R4520V50A12-1AA22R4520V50A14-1AA22L4520V60A5-1CC22R4520V60A8-1AA22R4520V60A8-1CC22R4520V60A11-1AD22R4520V60A12-1AA22R4520V60A12-1CC22R4520V60A14-1CC22R4525V42A14-1AD22R4525V42A17-1AA22R4525V42A17-1CC22R4525V42A17-1DD22R4525V42A17-1DA22R4525V42A21-1AA22R4525V42A21-1BB22R4525V42A21-1CC22R4525V42A21-1BA22R4525V42A21-1BD22R4525V42A21-1DA22R4525V42A21-86AA22R4525V42A21-86DD22R4520V45A5-1BB22R4525V50A12-1DD22R4525V50A14-1AA22R4525V50A14-1DD22R4525V50A17-1AA22R4525V50A17-1CC22R4525V50A17-1DD22R4525V50A21-1AA22R4525V50A21-1CC22R4525V50A21-1DD22R4525V50A21-1BB22L4525V50A21-1AB22R4525V50A21-1AD22R4525V50A21-1DA22R4525V50A21-1DC22R4525V50A21-86AA22R4525V50A21-86BB22R4525V60A12-1DD22R35V30A-1D-22R35V30A-1B-22L35V30A-86A-22R35V35A-1B-22R35V35A-1C-22R35V35A-1D-22R35V38A-1A-22R35V38A-1B-22R35V38A-1C-22R35V38A-1D-22R35V38A-1A-22L35VQ35A-1C-2045V42A-1A-22R45V42A-1B-22R45V42A-1C-22R45V42A-1D-22R45V42A-86A-22R45V42A-86B-22L45V42A-86C-22R45V42A-86D-22L45V50A-1A-22R45V50A-1B-22L45V50A-1C-22R45V50A-1D-22L45V50A-86C-22R45V50AM-86D-22R45V60A-1A-22R45V60A-1B-22R45V60A-1C-22R45V60A-1D-22R45V60A-1A-22L45V60A-1B-22L45V60A-1C-22L45V60A-1D-22L45V60A-86A-22R45VQ60A-86C-202520V12A2-1BB22R2520V12A2-1CA22R2520V12A5-1DD22R2520V12A5-1AD22R2520V12A8-1AA22R2520V12A8-1CC22R2520V12A8-1DD22R2520V12A11-1AA22R2520V12A11-1DD22R2520V14A5-1BB22R2520V14A5-1CC22R2520V14A51DD22R2520V14A8-1BB22R2520V14A8-1CC22R2520V14A8-1DD22R2520V14A11-1AA22R2520V14A11-1BB22L2520V14A11-1CC22R2520V14A11-1DD22L2520V14A12-1AA22R3520V30A8-1AA22R3520V30A8-1CC22R3520V30A8-1DD22R3520V30A8-1CB22R3520V30A8-1DC22R3520V30A11-1BB22R3520V30A11-1CC22R3520V30A11-86CC22R3520V30A12-1AA22R3520V30A12-1AD22R3520V30A12-1DC22R3520V30A14-1AA22R3520V30A14-1AA22L3520V30A14-1CB22R3520V35A5-1BB22R3520V35A5-1CC22R3520V35A8-1CC22R3520V35A81AD22R3520V35A8-86AA22L3520V35A11-1DD22R3520V35A14-1BB22R3520V38A5-1AA22R3520V38A8-1BB22R3520V38A11-1AA22R3520V38A11-1BA22R3520V38A12-1AA22R3520V38A12-1BB22R3520V38A12-1CC22R3520V38A12-1DC22R3520V38A14-1AA22R3520V38A14-1AD22R3525V25A12-1AA22R3525V25A12-1BB22R3525V25A12-1CC22R3525V25A12-1CB22R3525V25A14-1BB22R3525V25A14-1AD22R3525V25A14-1DA22R3525V25A14-1DC22R3525V25A17-1AA22R3525V25A17-1BB22R3525V25A171DD22R3525V25A17-1DA22R3525V25A21-1AA22R3525V25A21-1CC22R3525V25A21-1BA22R3525V25A21-86AA22R3525V30A10-1DD22R3525V30A12-1AA22R3525V30A12-1DD22R3525V30A14-1AA22R3525V30A14-1CC22R3525V30A14-1DD22R3525V30A14-1DA22R3525V30A17-1AA22R3525V30A17-1CC22R3525V30A17-1DD22R3525V30A17-1DA22R3525V30A21-1BB22R3525V30A21-1CC22R3525V30A21-1DD22R3525V30A21-1DA22R3525V35A12-1DD22R3525V35A14-1AA22R3525V35A14-1CC22R3525V35A17-1AA22R3525V35A17-1BB22R3525V35A17-1CC22R3525V35A17-86CB22R3525V35A21-1AA22R4525V60A12-1CC22L4525V60A12-1AA-22R4525V60A12-1CC-22R4525V60A17-1AA22R4525V60A17-1CC22R4525V60A17-1CC22L4525V60A21-1AA22R4525V60A21-1CC22R4525V60A21-1DD22R4525V60A21-1DD22L4525V60A21-1BA22R4525V60A21-1BD22R4525V60A21-1DA22R4525V60A21-86AA22R4535V60A25-1AA-22R4535V60A25-1CC-22R4535V42A25-1AA22R4
