GB/T 20421.2-2006 Hydraulic fluid power—Determination of characteristics of motors—Part 2:Startability
Abstract
This part of GB/T 20421 describes two methods for determining the startability of rotary hydraulic motors. These are two similar measurement methods, the constant torque method (see Chapter 6) and the constant pressure method (see Chapter 7). Since the results obtained are the same, there is no difference in superiority between the two methods. In Appendix A, explanations of additional physical quantities and letter symbols are provided. The accuracy of the measurement is divided into three grades, A, B, and C, and explanations are given in Appendix B.
