逻辑分析法诊断液压系统故障时，分为两种情况：a对较为简单的液压系统，可以根据故障现象，按照液压源一控制元件-执行元件的顺序在液压系统原理图基础上，逐项检查并根据已有检查结果．排除其他因素．逐渐缩小范围，直至正确推理分析出故障原因并排除之；b对于较为复杂的液压系统．通常町根据故障现象按控制油路和主油路两部分进行分析，逐一将故障排除之。3129310802PGPE030A194*BE*OJ*15-303129310805PGPE030A194BEOK17-303129310807PGPE030A194*BE*OK*17-303129310808PGPE030A194*JE*AB*07-303129310809PGPE030A294*BEEG10-253129310810PGPE030A194*BEOJ12-303129310813PGM030A994*MEAB12-25*3129310816PGM030C894MEAB05-**3129310817PGM030A842*BEOF10-25*安全。在进行液压系统故障诊断时，应遵循安全的原则。3129320069PGFD030BBYED10-1GED10BY3129320126P30B196*BIAC12-65*FSED10-13129320154PGP030C597*BIAG15-**BFEC10-13129320159FD30BBY*AD20-1JAD20BY*3129320165FD30BBYED20-1HJAB07BY3129320193P30B542BI**20-30JCAB05-13129320271PE30B294*BIEG10-25DEC12-13129320311PGP030B278*BI*OG15-25DOG15-13129320324FD30BBYED15-1FED15BY3129320368FD30BBYID10-1NID10BY3129320406P30B642BYAL20-43**AB10-1液压系统中，bai选择的参数顺序是这样du的：先确定液压缸活塞zhi杆的动作速度和作用力→确定液压系统dao的所需流量和所需压力→确定油泵的类型→按照油泵的要求选择配套电机，也就说：液压系统中的电机要根据油泵的要求来选择。流量×工作压力÷机械效率=液压系统功率一般在选型的时候取大于功率的50%左右3349116324PGP511A0045CS1Q2NJ7J5B1B13349111909PGP511A0050CL6D4NE3E3B1B13349116261PGP511A0050CS2A2ND5D4B1B1+ZR3349112708PGP511A0060AA1H2ND5D4B1B13349112621PGP511A0060AA1H2NE5E3B1B13349112093PGP511A0060AA1H2NL1L1B1B13349112216PGP511A0060AF1D4NJ7J5B1B13349112715PGP511A0060AF1H2MJ7B1LABH3349112230PGP511A0060AJ5D3NE3E3B1B13349112536PGP511A0060AK1H2NE3E2B1B13349112534PGP511A0060AK1H2NE5E3B1B13349112629PGP511A0060AK1H2NL1L1B1B13349112751PGP511A0060AL1H2NE5E3B1B1
