Advanced Hydraulic Pump Test Bench
Specification
- Functional requirements: Available to mainly test hydraulic pumps (open pumps, closed pumps, double open
pumps), high-speed motors to be tested.
and low-speed hydraulic motor is tested in simple way.
The computer on the test bench acquires the test data of hydraulic
pump and the hydraulic motor and record them and then form
displaying curves and print test report.
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.
- Assisting test of hydraulic valves, hydraulic cylinders, etc,
III. Function and parameters of the test bench
1. driving mode: by electric motor, 160kw+5.5KW+5.5KW+0.75KW+0.75KW0.75KW
2, speed adjusting mode: frequency converter control, 100-3000r/min.
3, loading mode: 3-way loading, through manual relief valve,
38Mpa+38Mpa+31.5MPa
Triple pumps can be tested
4. Oil supply from test bench to the tested pump :: both self
priming ,and in forced way
5. what can be tested? the test bench mainly test open hydraulic pumps, tandem open
pumps, closed pumps, and high-speed hydraulic motors. , and
auxiliary test hydraulic valves and hydraulic cylinders ,etc.
6 The test bench is able to test both clockwise rotation and
counterclockwise rotation pumps
7. the test bench can generate and print test report.
8. the test bench is with filter equipment for recovery of leakage
oil.
9,oil tank volume: 1200L
10. oil in and oil out are filtered with alarm function
11. Cooling way: air cooling radiator
- maximum flow of system: ≦380L/min+380L/min+150L/min
