Description

The LIYA Semi-Automatic (Motorized) range of 2000 kN and 3000 kN capacity compression testing machines have been designed for reliable and consistent testing of a wide range of specimens. Machines confirms all EN, ASTM and BS standards written above. These also meet the requirements of CE norms for the safety and health of the operator.

The EN Semi-Automatic Concrete Compression Testing Machines consist of;

Load Frame,

Semi-Automatic Hydraulic Power Pack,

Digital Readout Unit

Distance Pieces, Ø 205×25 mm, Ø 205×50 mm and Ø 205×80 mm,

Upper Platen (with ball seating assembly) Ø300 mm,

Lower Platen Ø300 mm,

Loading Cylinder Assembly & Limit Switch for safety,

Front and Rear Protective Doors for safety.

The ASTM Semi-Automatic Concrete Compression Testing Machines consist of;

Semi-Automatic Hydraulic Power Pack,

Digital Readout Unit

Distance Pieces, Ø 165×80 mm, Ø 165×50 mm and 2 pcs. Ø 165×25 mm,

Upper Platen (with ball seating assembly) Ø165 mm,

Lower Platen Ø165 mm,

Loading Cylinder Assembly & Limit Switch for safety,

Front and Rear Protective Doors for safety.

Concrete Compression Load Frame

Capacities of 2000 kN and 3000 kN Load Frames are most popular and available models for welded type frames.

The load frame provides the stability needed for accurate and repeatable test results over the years of operation. The machine’s hydraulic power pack, control and read out units are positioned on the right hand side of the load frame for easier accessibility, increased productivity and for safer operations.

Upper Platens/Lower Platens

Upper Platen (with ball seating assembly) Ø 30 x 5 cm and Lower Platen Ø 30 cm x 5 cm.

The platens enable the testing of a wide variety of cylinder, cube blocks or similar samples.

  • Manufactured from high quality steel, which is then hardened, smoothed and finished.
    • The roughness value for the surface texture of the auxiliary platens is ≤ 3.2 µm.
    • Ø 165 mm, Ø 216 mm and Ø 300 mm Upper Platen (with ball seating assembly) and Lower Platen have centering rings on the lower platens for proper centering of 100 mm and 150 mm cube, 100 mm and 150 mm cylinder samples.
    • Ø 300 mm Upper Platen (with ball seating assembly) and Lower Platen has an specimen centering apparatus on lower platen as standard 150 mm cube and ∅ 150 mm cylinder.

Block Platens with Sliding Rail Assembly 

STANDARDS: EN 772-1, 12390-4

Block Platens with Sliding Rail Assembly are installed on the compression testing machines for testing concrete blocks and other structural materials. The Sliding Rail Assembly allows the platens to be easily installed without removing the existing Ø 300 mm compression platens. This assembly should be factory installed.

It should be noted that after installing, the vertical clearance between the platens decreases by 50 mm.

Block Platens Lifting Assembly is used for easy removal of the lower platen of Block Platens and easy replacement of the distance pieces between the piston and the lower platen.

Distance Pieces

Distance pieces are used to reduce the amount of vertical clearance between the upper platen and the lower platen. Supplied with Ø205 mm distance pieces.

Loading Cylinder Assembly & Limit Switch

All frames have a single acting up stroking ram. The diameter of piston changes with regard to the capacity.

The maximum ram stroke is 50 mm, a limit switch is fitted to prevent over travel of the ram which cuts the power to the pump for safety.

At the end of the test process to start a new test the piston returns to default position.

The pressure transducer is used for load measurements.

There is a low friction coaxial PTFE seal between the cylinder and the piston fitted to the cylinder.

SEMI-AUTOMATIC (MOTORIZED) HYDRAULIC POWER PACK AND LPI BATTERY OPERATED DIGITAL READOUT UNIT 

Semi-Automatic (Motorized) Hydraulic Power Pack

The Semi-Automatic (Motorized) Power Pack, controlled by a pressure rate control valve is designed to supply the required oil to the load frames for loading. The power pack can load different frames with required pace rates. A rapid approach pump is supplied as standard. The power pack is equipped with a safety valve (maximum pressure valve) to avoid machine overloading. Maximum working pressure of the system is 600 bar.

Dual Stage Pump

The dual stage pump is formed by two groups;

  1. Low pressure gear pump
  2. High pressure radial piston pump

On the dual stage pump, a high delivery, low pressure gear pump is used for rapid approach, while a low delivery, high pressure durable variable output pump is used for test execution. The rapid approach facility shortens the time interval from piston start until the upper platen touches to the specimen. This excellent feature helps to save a lot of time when a large number of specimens are going to be tested.

Motor

The motor which drives the dual pumps in an AC motor.

Distribution Block

A distribution block is used to control the oil flow direction supplied by the dual stage pump, the following parts are fitted to the distribution block; Safety valve (max. pressure valve), Transducer and Pressure relief valve.

High Precision Pressure Transducer 

The LIYA range of Semi-Automatic and Automatic Machines can be upgraded with option High Precision Pressure Transducer special calibration Class 1 starting from 1% of the full range.

This unique performance enables the machines to be used for a considerable number of applications including:

• Early age(2 or 3 days) compression strength tests
• Flexural and splitting tests by using proper accessories
• Mortar (Cement) compression tests by using proper accessories
• Core Testing

Oil Tank

The tank includes enough oil to fill the mechanism which pushes the ram during the test. The level and oil temperature can be seen on the indicator fitted to the tank. It has 25 L capacity. Hydraulic motor oil, number 46, must be used.

LPI Battery Operated Digital Readout Unit 

The LPI Battery Operated Digital Readout Unit has been designed to use with load cells or pressure transducers on different material test applications.

• The unit is operates with DC voltage source of -1,5 to 1,5 volts
• Can operate with 2 x AA batteries or with adapter.
• Real time numeric display of load and load pressure
• 1 channel with two different calibration table (can be used for 2 sensors)
• Peak hold property
• Multi-point calibration
• Easy preload zeroing
• 8 keys keyboard
• Serial port for PC or printer

The LPI is a very convenient readout unit that can be used to retrofit old compression machines with manometer (gauge).
