Hydraulic Damper Test Bench

About

Damper test bench is a high performance test equipment to test the damper assembly of the main HSU unit. Testing to be perform to check the Differential pressure creating capacity of the damper assembly. Damper test bench has the cage to assemble the Damper in it. Pressure of upto 150 bar and flow upto 200 LPM is provided on both side of the cage to check the Jounce and Rebounce characteristics of the damper assembly. Meanwhile, graph of pressure difference V/s flow is plotted and Test report is generated in the end of test.

  • 200 liter oil storage tank.
  • High pressure filter of 10 micron.
  • Jounce Flow (LPM) 50-200, Acceptable Pressure Drop Across Damper(bar) 72.8-23.5, 115.8-76.1, 117.2-100.4, 131.0-105.1
  • Rebound Flow (LPM) 60-200, Acceptable Pressure Drop Across Damper(bar) 76.4 - 33.3, 81.7 - 66.9, 93.7- 80.3
  • Temperature gauge: 0-90 Deg C.
  • Air cooled oil cooler 220 lpm, 50 Deg C, 18.5 KW, Pr: 15-20 bar.
  • Delivery hose 300 bar.
  • Motor drive : Suitable for 55kw
  • Anti-Vibration Pad: 300 kg.
  • NRV (Line Mounted): 220 LPM.
  • Filler Breather: 10 micron, 90 LPM.
  • Suction Strainer: Flow rate: 300 LPM, 2.5” BSPF.
  • 400 Ltr Hydraulic tank with baffle plate & slope in the bottom.

The Damper assembly has the main purpose of creating differential pressure within the HSU unit. Damper assembly creates the partition between hydraulic oil filled in bottom part of main cylinder. It absorbs the shock and jerks of the K9 VAJRA Tank and ensures smooth rebounce and jounce movement.

Key Features

  • Pilot operated direction control valve (ng25) is provided in the system to ensure proper connection of A to B
  • Vfd panel with ABB variable frequency drive with flow regulator to control the RPM to the motor and subsequently regulates the flow.
  • Single high performance drive is used to ensure the rotation of the motor is anticlockwise.
  • Single high performance drive is used to ensure the rotation of the motor is clockwise.
