Compression Testing Machine

Product Details:

Salient Features:

• Simplified design for ease of operation and maintenance
• Safety provisions against over load and over the travel Highly rigid loading frame
• FSA's guarantee of quality
• Motor driven crosshead for easy adjustment facilitates rapid fixing of the test specimen
• Wide range of accessories available Straining at variable speeds to suit a wide range of materials

Application:

• Compression Testing Machine have a wide range of applications. It is designed to check materials under compression, bending, Transverse, Brinell Hardness & Shear testing etc.

Construction:

• The machine consists of 2 units viz. the loading unit and control panel.
• A. Loading Unit: It consists of a base at its center, hydraulic cylinder, piston and two screws. A crosshead is mounted on the screws and is driven by a motor for rapid adjustment of test height. A table is mounted on the piston with a ball joint in between. The precisely ground piston and the individuallylapped cylinder piston assembly ensures a smooth transfer of the force with minimum friction losses.
• B. Control Panel: It consists of a hydraulic system with a power pack, load measuring & indicating system and electrical system.
• A. Hydraulic System: It consists of a hydraulic power pack with a directly driven radial plunger pump. Power pack consist of the oil filter, oil strainer, air breather, drain plug, oil level indicator etc. It can generate an oil pressure up to 250 bar. A pressure compensated flow control valve is provided for controlling the oil flow to cylinder thereby archiving a desire piston speed.
• B. Load Measuring & Indicating system For dial type machines: The oil pressure in the main cylinder is transferred to the small dynamometer cylinder. The dynamometer piston iskept rotating at
  slow speed to ensure dynamic friction condition. The piston exerts a force proportionate to the pressure on the hanger connected to
  the pendulum through an auto range selecting lever system. The force defects the pendulum. A damping system is provided to
  ensure the slow return of the pendulum. The Pendulum lever pushes a rack which slides over two pulleys a rack movement is proportional to the load. A pinion engaged with a rack rotates and moves the pointer. A window type dial is provided for easy and clear indication. A continuous roll type recorder is provided for plotting a load verses deformation graph.
• For Electronic & Computerised Machines: The oil pressure in the main cylinder is transferred to an electronic pressure transducer which gives the proportional electronic signal.
  Displacement measurement is carried out by a rotary encoder mounted on the base. The linear motion of the piston is. Converted in rotary motion and the encoder undergoes angular displacement. This gives the proportional electronic signal for deflection. The pressure transducer and encoder signals are given to electronic panel / computer.
• C. Electrical System: A separate switch box and the electrical panel is provided. Both hydraulic pump motor and cross head motor have interlocks. Limit switch
  is provided for over travel safety. A push button station is provided on the control panel with UP, DOWN pushbuttons for cross head
  motor and ON, OFF push buttons for the pump motor.
• Operation: The specimen to be tested is to be kept on the machine table, The position of the cross head can be adjusted by operating UP, DOWN push buttons. The Compression test can be conducted by positioning the specimens between the compression plates. The Bend /
  Transverse tests can be conducted by positioning the specimen over the bending supports. The load is applied by
  operating the hand operated valves ergonomically placed for ease of control.
