{1} Comparison of Design Performance Test Standards for High viscosity Pumps
(2) Different testing acceptance indicators. The acceptance standard of GB/T21411 is that at a speed of (150 ± 7) r/min, the measured values of flow and torque at zero pressure difference and pressure difference should have an error within ± 10% of the manufacturer's published curve. The standard of ISO15136 in hydraulic testing is that at a speed of 300r/min and a specified temperature, the measured pressure meets or exceeds the specified pressure level, the displacement per revolution is within ± 5% of the instruction manual, and the torque is within ± 10% of the instruction manual for all pressure ranges. ISO 15136 has strict requirements for the acceptance of hydraulic testing"
