GENERAL PROPERTIES
UTM-3000.FPR automatic 500 kN tension / 1000 kN compression testing machine has been designed to meet the need for reliable and consistent tensile testing of steel rebars up to 26 mm diameter and compression testing of concrete cube samples up to 150 mm and cylinders up to 160×320 mm.
This lightweight low cost and high accurate machine is suitable for use both in the site testing and educational purposes. UTM-3000.FPR feature the complete automatic test cycle with a closed loop digital readout. Once the specimen parameters have been introduced, it is sufficient to press the START button to complete the test.
UTM-3000.FPR tension/compression test machines consist of three main parts: Frame, power pack and data acquisition & control system. On the measuring system pressure transducer is used for load measurements and Linear Potentiometric Displacement Transducers is used for crossheads separation measurement and plotting stress/elongation graph. Each part has been designed to manufacture machines with a high degree of mechanical stability and complies to EN ISO 6892-1(method B), 15630-1 (with suitable platen set) standards.
FRAME
The load frame is a welded steel fabrication carrying the ball-seated upper platen or the universal grip assembly. Positively located on the loading ram which is protected from debris by a cover, the lower platen is marked for the centering of cube and cylinder specimens. The dimensions of the frame allow the tension tests on steel rebar up to 26 mm dia., and flat specimens up to 15mm thick and 50mm wide, compression tests on concrete cylinders up to 320 mm long x 160 mm diameter and cubes up to 150 mm. The machine is supplied complete with 5 pcs. 90 mm x Ø165, 2 pcs. 50 mm x Ø165 and 2 pcs. 30 mm x Ø165 distance pieces. To test samples shorter than 150 mm extra distance pieces should be ordered. The frame has a double acting piston with over travel protection to stop the motor when the maximum platen or grip travel be reached.
The main characteristics are;
- High stability welded assembly
- 500 kN tensile and 1000 kN compression capacity
- 100 mm piston stroke with safety limit switch
- Upper compression platen with ball seating assembly and lower platen included
- Set of two tensile grips and jaw faces included
- Platen hardness of min 55 HRC
- Distance pieces included
POWER PACK
The UTC-4830 Automatic Hydraulic Power Pack, dual stage, controlled by U-Touch PRO Control Unit is designed to supply the required oil to the load frames for loading. The power pack is very silent, even at full load and can load the specimen between 1 kN/sec. to 20 kN/sec, with an accuracy of ±5%. A rapid approach pump is supplied as standard. A safety valve (maximum pressure valve) is used to avoid machine overloading.
Dual Stage Pump
The dual stage pump is formed by two groups:
- Low pressure gear pump
- 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 radial piston 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 alot of time when a large number of specimens are going to be tested.
Motor
The motor which drives the dual pump is a 0.75 kW AC motor which is controlled by an Omron J7 motor inverter. The variation in the oil flow is executed with the variation of the rotation speed of the 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;
a- Solenoid valve
b- Safety valve (maximum pressure valve)
c- Transducer
d- Low pressure gear pump
e- High pressure radial piston pump
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 20 L capacity. Hydraulic motor oil, number 46, must be used.
U-Touch PRO Control Unit
TFT Graphic Display U-Touch PRO Control Unit is designed to control the machine and processing of data from load-cells, pressure transducers or displacement transducers which are fitted to the machine.
All the operations of U-Touch PRO are controlled from the front panel consisting of a 800×480 pixel 65535 color resistive touch screen display and function keys 4 analogue channels are provided for load-cells, pressure transducers or displacement transducers.
