Comprehensive-function Hydraulic Pump / Motor Test bench
Function configuration and parameters of test bench:
The hydraulic comprehensive test bench mainly test single pumps and double hydraulic pumps, open pumps and close hydraulic pumps; low speed, high speed hydraulic motors (pump working condition test), and do the auxiliary test of hydraulic cylinders, hydraulic valves, etc.
Driving mode: output power of electric motor is 110kW; Speed 0-1500r / min
Loading mode: Pump loading: dual way loading of proportional relief valve, maximum 35MPa
oil supply mode:
low-pressure oil pump: : 350 L / min (0-3 MPa) or Self-priming oil supply;
Pilot auxiliary oil: 15L/ min, 0-4Mpa
Data display mode:
1) Flow, temperature and speed are displayed in digit.
4) If the filter is blocked, alarm;will be given by red light.
5) All the data will be displayed on computer in table of curve graph,.
working medium: isovg46 hydraulic oil
Oil tank volume: designing is 1500L, real volume is 1300L
Test Items
1, Displacement test: no-load pressure test, displacement test
2, Test of volume efficiency: the volume efficiency test under rated operating conditions,
3. Overload test: maximum displacement of hydraulic pump or motor (high speed), nominal speed, running for less than 1 minute under rated pressure of 110% or under the maximum pressure
4. External Leakage test: in the test above, check the leakage of the sealing parts.
