ISO 4409 Hydraulic Motor Test Bench For Motor Performance Testing Equipment
200N.m
Introduction of Motor Performance Testing Equipment:
Motor test bench is used to test all kinds of motor machine
comprehensive performance indicators of the test device, can
measure the current, voltage, power factor, electric power; torque,
speed, power; efficiency; push and pull; slewing angle and other
performance parameters. According to the test piece can be divided
into hydraulic motor test bench, pneumatic motor test bench,
low-speed motor test bench, high-speed motor test bench and so on.
Introduction of hydraulic motor test bench:
Hydraulic motor testing equipment is a kind of equipment used to
test and evaluate the performance of hydraulic motors. It simulates
the actual working conditions to test various performance and
functions of hydraulic motors to ensure that they work properly and
meet the expected performance requirements.
Standard of Hydraulic motor testing equipment:
ISO8426:2008 Hydraulic fluid power — Positive displacement pumps
and motors — Determination of derived capacity;
ISO4409:2019 Hydraulic fluid power— Positive- displacement pumps,
motors and integral transmissions — Methods of testing and
presenting basic steady state performance;
ISO4392-1:2002 Hydraulic fluid power — Determination of
characteristics of motors — Part 1: At constant low speed and
constant pressure;
Test items of motor testing equipment:
The motor test bench can test the hydraulic motor's torque, speed,
efficiency; inlet pressure, outlet pressure, differential pressure;
circulating flow, leakage flow, volumetric efficiency, total
efficiency; outlet temperature, temperature difference and so on.
| Volumetric Efficiency | Calculation of the volumetric efficiency of a hydraulic motor by
measuring its input and output flows under specific conditions |
| Rated Flow | Tests the flow of a hydraulic motor at rated speed to see if it
meets design requirements. |
| Rated Speed | Test the speed of the hydraulic motor at rated pressure to ensure
that it meets the design requirements. |
| Rated Pressure | Test the output pressure of the hydraulic motor at rated speed to
see if it meets the design requirements. |
