GB/T 20421.3-2006 Hydraulic fluid power—Determination of characteristics of motors—Part 3:At constant flow and at constant torque
Abstract
This part of GB/T 20421 specifies the method for determining the low-speed characteristics of quantitative or variable displacement hydraulic motors under constant flow and constant torque. This method includes tests under low-speed conditions, where the frequency of hydraulic pulses may have a significant impact on the stable and continuous torque output of the motor and affect the system to which the motor is connected. The accuracy of the measurement is divided into three grades: A, B, and C, which are described in Appendix A.
