③扭矩的测量就用扭矩仪来测定。对于液压马达来说，注入液压马达的液压油所产生的能量和马达输出轴所产生的能量理论上是相等的，这就是马达的能量守恒，即马达输入输出的功率相等。可以用下面这个公式来表示：P液压油=P输出轴a、液压油的功率=流量X压力b、输出轴的功率=扭矩X角速度c、流量X压力=扭矩X角速度经过推算得出：流量X压力=扭矩X2πX转速9510390098AZ-P-N-12-020-RPC12MA9510390099AZ-P-N-12-022-RPC12MA9510390100AZ-P-N-12-025-RPC12MA9510390101AZ-P-N-12-028-RPC12MA9510390102AZ-P-N-12-032-RPC12MA9510390103AZ-P-N-12-036-RPC12MA9510390104AZ-P-N-12-020-LPC12MA9510390105AZ-P-N-12-022-LPC12MA9510390106AZ-P-N-12-025-LPC12MA9510390107AZ-P-N-12-028-LPC12MA9510390108AZ-P-N-12-032-LPC12MA9510390109AZ-P-N-12-036-LPC12MA力士乐PGH型号PGH4-2X/032RE11VU2运行噪音很低振动小密封间隙补偿使在低速、低粘度下也能***运作适合多种不同速度和粘度范围所有安装尺寸和额定尺寸原件可相连可和叶片泵和轴向柱塞泵连接使用R900778549PGH4-2X/063LR07VU2-A436R900770609ABAPG-PGH4-080E4/200L-4-B0/SER900770179PGH5-2X/250RE07WU2R900766037PGH2-2X/006RR07VU2-A334R900754794PGH4-2X/063RE07WE4R900932165PGH4-2X/063RE07VE4R900932159PGH4-2X/050RE11VU2R900932141PGH4-2X/032RE11VU2R900932140PGH4-2X/025RE11VU2R900932139PGH4-2X/020RE11VU2R900245596PGH4-2X/025RE11VU2-A280BR900204884PGH5-2X/200RE07VE4-A388)
