GB/T 20421.1-2006 Hydraulic fluid power—Determination of characteristics of motors—Part 1:At constant low speed and at constant pressure
Abstract
This part of GB/T 20421 specifies the determination method for the low-speed characteristics of quantitative or variable displacement rotary hydraulic motors. This method includes tests under low-speed conditions, under which 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, and the explanations are given in Appendix A.
