WEW-300B Tension Test Machine

Specifications tension test machine is a computer display manual universal testing machine, do tension, compression, bending, and other test

  1.  Instruction Model WEW-300B servo tension test machine is designed of computer display manual control by valve, main engine controller separately fixed. It has the characteristics of operation amenity, working steady, high accuracy and loading steady. It can implement the experimentations such as the tensile, compression, bending, shearing etc. to the metal, nonmetallic composite materials.   2.  Structure Model WEW-300B servo tension test machine consists of an adjustable support (base, screw thread pole, moveable crossbeam (lower clamp set)) and a working frame (working oil tank, piston, platform, support crossbeam (upper clamp set)). Element of the machine: high-pressure oil pump supply oil to the working oil tank, the piston moves and press board and upper crossbeam to do stretch and press test. The stretch test is done in the space between upper crossbeam and movable crossbeam. The life motor, gear, chain drive rotate at a same speed to move the crossbeam.   3.  PC display universal testing machine introduction It is electro-hydraulic universal material testing and analysis system, has the functions of test the collected data, automatic analysis, print report and curve. Applicable to stretch, compress metal, compress cement, and concrete nonmetal materials tests. It is an ideal testing system for industrial and mining business, commerce arbitration institution, scientific research institution, colleges, construction project quality control institution and so on.   4.  Characteristics It adopts the four vertical pillars (2 columns and 2 lead screw) framework structure. It is of the more stable construction and the more guaranteed rigidity. It utilizes the hydraulic chuck sample automatic clamping. It employs the high precision pressure-operated sensor to measure the hydraulic force. It is of the high measuring accuracy and the wider range. It uses the high accuracy motion transducer. It adopts PCI wire control mode. It utilizes Windows XP operation system. It can be allocated with the touch screen which is more beneficial for the operation and control modes such as the constant rate force control, constant rate stress control, constant rate deformation control, constant rate stroke control, low cycle fatigue control, consumer self-programming control etc. It can draw the multiple experimental curves such as the force-deformation, force-shift, stress-strain, force-time and so forth. It can partially the experimental curve and hold the additive comparison to the multi-curves. It can automatically seek the multiple technical parameters such as elastic module E, upper yield strength ReH, lower yield strength REL, stipulated non-proportional elongation intensity Rr, tensile strength Rm, stipulated total elongation intensity Rt, yield point percentage elongation etc. It can also print the complete experimental report and curve. It comprehensively conforms with GB/T228-2002 requirements.   5.  Security protection Position limiter; emergency switch; the control system can protect automatically once over-load, over-currency, over-voltage, over-temperature   6.  Software   6.1 Two-level authorization passwords management. 6.2 live indication of load, position and strain, simultaneously. 6.3 peak indication of load, position and strain, during and after test.   6.4 live indication of load, position and strain rates during test.   6.5 live X-Y graph of user-selected curve: stress vs. strain; load vs. position; stress vs. position; load vs. strain; load vs. time; position vs. time etc.   6.6 automatic saving of transducer information to file for later recall, re-graph and recalculation.   6.7 automatic saving of results to file for statistical computation and export to spreadsheet and database programs: Access and Excel.   6.8 print single test reports including X-Y graph on a single page 6.9 select from a predefined analyses including: peak load, peak stress, tensile strength, Rp0.2, Rt0.5, ReH, ReL, elongation break and so on.   6.10 specimen geometries of flat, round, cylinder, square, tube, pipe.   6.11 define, save and recall tests setups to minimize errors and save time.   6.12 select the international units, such as “N”, “kgf”, “lb”, “mm”, “in” and so on. 6.13 calibration: adjusting hardware of load cell by software, make it meet testing standard.   7.   Electro-hydraulic measurement control cabinet   7.1 internal micro-computer control panel, communicate with PC by RS232 series port.   7.2 adopts famous brand import integrated component, such as BB, AD,Atmel, and so on, fully digitized design.   7.3 adopts integrated high precision meter amplifier. 7.4 18 bits high accuracy analog-to-digital conversion.   8.
