Comprehensive-function Hydraulic Pump / Motor Test bench

Brief introduction

The hydraulic comprehensive test bench is a specialized equipment used for testing and evaluating hydraulic components in maintenance enterprises. The system selects high-quality hydraulic and electrical components and accessories from home and abroad, and has the characteristics of compact structure, reliable quality, reasonable design, easy operation and maintenance,

The hydraulic system of this test bench adopts a closed oil tank structure, which allows it to work in a dusty environment. However, attention should be paid to regularly cleaning the dust on the hydraulic equipment during use to ensure that the hydraulic system has good heat dissipation and oil cleanliness.

Specification

• Functional requirements: Available to mainly test hydraulic pump (open, closed, double open pump), high-speed motors
• .

The test bench also do the auxiliary test for hydraulic oil cylinder, low speed hydraulic motor and valves

High speed motor to be tested according to the method of testing pumps.

Low speed motor is tested in simple method. Mount a pump onto the test table. The pump is connected with the 90KW electric driving motor. Let the electric driving motor drive the pump, then let the pump drive the low-speed hydraulic motor.

Function and parameters of the test bench

1. Driving mode: by electric motor, 90kw+22KW+1.5KW+0.75KW

2, Speed adjusting mode: frequency converter control 0-1500r/min.

3, Loading mode: two-way loading, through guide relief valve, 35 Mpa, Tandem pumps can be tested.

4.max. flow of system: ≦330L/min× 2 loops

5. High-pressure auxiliary system:

max pressure of 5MPA, max, flow is ≦7.5L/min

6. Low- pressure auxiliary system:

max pressure of 3MPA, max, flow is ≦330L/min

7. The test bench should be used where the temperature is 10-60℃

8. air-cooling radiator for cooling oil

9. the sensor and the controlling electric power: DC24 V

10.. Displaying mode: rotation speed, flow, and the temperature are showed in digital .meter. Pressure is displayed by mechanical meter. All the test data will be showed on the computer.

11. Oil supply from test bench to pump needing test:: both self priming ,and in forced way

12. The test bench is able to test both clockwise rotation and counterclockwise rotation pumps

13, The test bench is with an oil filter equipment cart for recycling the leaked oil

14,oil tank volume: 1000L

15. oil in and oil out are filtered with alarm function

16, Generally the buyer is able to install the hoses onto the test bench after receiving the test bench. But if the buyer need the seller send a technician to go to his factory to install the test bench, he need bear the cost of the round air tickets, and food, hotel , accommodation in the country of the buyer.
