Energy Efficient Digital Hydraulic Motor Test Stand Computerized

Hydraulic Pump  Test Stand 

Specification

I. Functional Requirements: Capable of mainly testing hydraulic pumps (open pumps, closed pumps, double open pumps), and high-speed motors to be tested. Additionally, low-speed hydraulic motors can be tested in a simple manner.

The computer on the test bench acquires and records the test data of the hydraulic pump and the hydraulic motor, subsequently forming display curves and printing test reports.

II.
Test Items:

1. Displacement Test: Comprising no-load pressure test and displacement test.
2. Test of Volume Efficiency: Measuring the volume efficiency under rated operating conditions.
3. Overload Test: Involving the maximum displacement of the hydraulic pump or motor (at high speed), nominal speed, and running for 1 minute or less under rated pressure or the maximum pressure.
4. External Leakage Test: During the aforementioned test, inspect the leakage of the sealing parts.
5. Assisting Test of Hydraulic Valves, Hydraulic Cylinders, etc.

III. Function and Parameters of the Test Bench

1. Driving Mode: Powered by electric motor, 160kW + 5.5kW + 5.5kW + 0.75kW + 0.75kW + 0.75kW
2. Speed Adjusting Mode: Controlled by frequency converter, 100 - 3000r/min.
3. Loading Mode: Three-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 forced.
5. What Can Be Tested? The test bench mainly examines open hydraulic pumps, tandem open pumps, closed pumps, and high-speed hydraulic motors. Also, it conducts auxiliary tests on hydraulic valves and hydraulic cylinders, etc.
