Main parameter
Power: 160KW+5.5KW+5.5KW+1.5KW+1.5+0.8+0.75=175.55KW
Maximum pressure: 35Mpa
Flow of main system: 400L+400L+200L
Speed of hydraulic pump: 0--1500r/min ( 1000r/min is advised)
Test method
Test of hydraulic pump: the main driving motor drives the tested pump to absorb medium from the hydraulic oil tank through the filter with blocking negative pressure alarm to complete the working action, and the pressure load is increased or decreased through the proportional overflow valve at the working oil port of the tested pump. (the auxiliary oil supply pump must be started for the closed circuit pump)
Test of axial high-speed hydraulic motor: same test method to the testing of pumps. (auxiliary oil supply pump must be started)
The maximum flow of low-pressure auxiliary system is ≤ 350L / min, and the maximum pressure of low-pressure auxiliary system is 3Mpa
The maximum flow of the pilot system is ≤ 15L / min, and the maximum pressure of the pilot auxiliary system is 4MPa
Working temperature range of equipment: 0-60 ℃
Equipment power requirements: AC380V 250A
Sensor and controlling power supply: DC24V
The computer automatically generates test reports, curves, data acquisition and printouts them.
Clockwise rotation and counterclockwise rotation can be tested
One oil filter cart is equipped to recover the oil leakage.
Oil tank volume: 1500L
Cooling mode: air cooling;
Test items
1, Displacement test: no-load pressure test, displacement test
2, Test of volume efficiency: the volume efficiency under rated operating conditions,
3. Overload test: maximum displacement of hydraulic pump or motor (high speed), nominal speed, running for 1 minutes or less under rated pressure or under the maximum pressure
4. External Leakage test: in the test above, check the leakage of the sealing parts.
Test accuracy
(1) Pressure: accuracy ± 0.1%, measurement range 0-35mpa (part 31.5Mpa)
(2) Flow: accuracy ± 0.5%, measuring range 5-400l / min
(3) Speed: accuracy ± 0.5%, measuring range 0-1500r / min
(4) Temperature: accuracy ± 1 ℃, measuring range - 20-100 ℃
