SANY Hydraulic Pump And Motor Test Bench
Product name Hydraulic pump and motor test bench
The test bench was developed for main pump and motor of SANY pump truck, excavator, and rotary drill.
The test range, the test items and the test requirements are consistent with the JB/T7039-7044 and other relevant industry standards.
Test projects
① No-load running test;② Determination of efficiency(Including the determination of displacement, the volumetric efficiency and the total efficiency determination);③ Overload test;④ The variable characteristics test of the variables agencies;⑤ Impact test;⑥ Monitoring of process parameters: monitor noise, vibration, temperature and motion stability and so on, which are generated in the testing process.
① No-load running-in trials, ② Start torque testing; ③ Power measurement (n, T) and efficiency measurement (including displacement measurement, volume efficiency and total efficiency determined); ④ Overload performance testing; ⑤ Low-speed stability testing, ⑥Variable institutions variable characteristics testing, ⑦ Impact test, ⑧ Process parameters monitor: including experimental process of noise, vibration, normal temperature, running smoothness monitoring, etc.
