柱塞泵柱塞往复运动总行程L是不变的，由凸轮的升程决议。柱塞每循环的供油量巨细取决于供油行程,供油行程不受凸轮轴操控是可变的。供油开端时间不随供油行程的改动而改动。滚动柱塞可改动供油终了时间，然后改动供油量。1．柱塞泵动力端油箱温度过高发生的缘由是什么？如何扫除？答：(1)毛病缘由：①油质变坏。②油量过少或过多。(2)扫除办法：①替换润滑油。②增减油量，使油量到达规则需求。R918C02771AZPGG-12-028/028LDC2020MBR918C02740AZPNF-11-032/014LDC0720KB-S0023R918C02614AZPNF-11-022/008RDC720KB-S0023R918C02598AZPNN-11-025/022RDC77KB-S0023R918C02594AZPNF-11-032/016RDC720KB-S0023R918C02591AZPNF-11-032/008RDC720KB-S0023R918C02478AZPF-10-022RSG20PB-S0012R918C02445AZPG-11-038LDC7KB-S0023R918C02440AZPN-11-025LDC7KB-S0023R918C02383AZPF-22-022LRR20MBR918C02381AZPF-21-022LFB20MBR918C02310AZPF-22-022RHO30KB***BOSCHREXROTH齿轮泵0510系列REXROTH力士乐齿轮泵采用修正渐开线齿形，用活动月牙板将高、低压腔分开，并在径向形成压力补偿，使得内外齿齿顶与月牙板之间形成几无间隙的密封，轴向动补偿盘则保证轴向间隙的良好密封，使得该泵的内泄漏减至***低。低压12Mpa、中压21Mpa、高压33Mpa。9510390066AZ-P-N-12-036-RQC12MA9510390067AZ-P-N-12-020-LQC12MA9510390068AZ-P-N-12-022-LQC12MA9510390069AZ-P-N-12-025-LQC12MA9510390070AZ-P-N-12-028-LQC12MA9510390071AZ-P-N-12-032-LQC12MA9510390072AZ-P-N-12-036-LQC12MA9510390073AZ-P-N-12-020-RQR12MB9510390074AZ-P-N-12-022-RQR12MB)
