1, Overview

1．1 Hydraulic comprehensive test bench is a special equipment used for the test and appraisal of hydraulic components in maintenance enterprises. The system selects high-quality hydraulic and electrical components and accessories at home and abroad. It has the characteristics of compact structure, reliable quality, reasonable design, easy operation and maintenance.

1．2 The hydraulic system of the test-bed adopts the closed oil tank structure, which is allowed to work in the environment with dust, but the dust on the hydraulic equipment should be cleaned frequently when using, so as to ensure that the hydraulic system has good heat dissipation and oil cleanliness.

2, Structural and functional features

2. 1. Manual remote loading; Computer display; Variable frequency and variable speed control, testing curve and report printing.

2. 2 test bench can test hydraulic pumps, hydraulic valves, hydraulic motors, hydraulic pump valve, cylinder inner leakage, curve characteristics, control test, etc.

2. 3. The designation of integrated oil loop block makes the system have the characteristics of less leakage, compact structure, easy disassembly and assembly.

2. 4. The output oil loop is arranged orderly and clear, easy to operate and install.

2. The test bench is divided into three parts: main pumping station, electric-motor driving platform and control bench.
