Shanghai Farrer Instrument Technology Co., Ltd. manufacturers of 15 years of processing capacity, assembly capacity, research and development capabilities. Can make the tensile testing machine / tensile machine to achieve high precision configuration. The overall performance of the tension machine can be measured by level. At present, there are mainly 1 level of tensile machines and 0.5 level of tensile machines in the market. And our company's tensile machine, tensile testing machine, all can reach the super 0.5 level of tensile testing machine. Specifically buy what kind of tension machine, mainly depends on the user needs to carry out which test? This requires detailed communication with the tension machine manufacturers.
Two, the choice of core accessories,
Rally machine price, the price of the test machine price increase is determined by the cost, this is a fact that we can not argue, then the choice of configuration is the main factor affecting the cost of the main accessories of the pulling machine:
Body, fixtures, sensors, etc., as well as the outer shell, the inner liner of the material of the production process, people often say a while! words: details determine success or failure, how to see the quality of a company and equipment, often need us to consider from the details, the more
is able to do things in detail the more manufacturers can be trusted. The following describes the advantages of the relevant test machine parts of FARI instruments.
Tension test machine/precision of the points of the tension machine force sensor
1.
First of all, the force sensor of the tension machine, there are sub-domestic sensors, imported domestic sensors, Shanghai Farrer Instruments uses the United States imported sensors, because the sensor is good or bad to determine the accuracy of the test machine and the stability of the force measurement, currently on the market with the sensor for the tensile strength of the machine. Small value of the general use of S-type sensors, large value of the general use of spoke sensors, sensors, generally for the internal resistance strain gage type, if the strain gage precision is not high or the fixed strain gage with the rubber aging resistance is not good in the or the sensor's material is not good will affect the sensor's accuracy and service life.
2.
The next point is the accuracy of the tensile testing machine/precision of the drive sensor parts of the movement of the ball screw, because the screw if there is a gap in the future to make the test data, will directly respond to the test of the maximum deformation and elongation after break. Currently on the market electronic universal testing machine has a screw is used T-shaped ordinary screw, so that one is a gap is relatively large, the second is the friction is relatively large use of short service life, Shanghai FARI instrument used for the German U Li Nieff high-precision non-gap ball screw, surface quenching hardness of HRC58-62, service life of up to a few decades. And to ensure that the accuracy is unchanged.
3.
Again is the point of tension tester/tensile strength machine precision tensile strength machine transmission system, the current market tensile strength machine transmission system, some use reducer, some use ordinary belt, the main drawbacks of these two transmission: the former need to add lubrication oil on a regular basis, the latter can not ensure that the transmission of the synchronization of the impact of the test results. Farrer's tension machine transmission system uses a full arc synchronous belt deceleration, to ensure the synchronization of transmission precision, high transmission accuracy, high efficiency, smooth transmission, low dry sound, no maintenance and long service life.
4.
Again is the point of tension tester / tension machine accuracy of the power source (motor) also known as the motor, currently on the market, some of the tensile strength machine using ordinary three-phase motors or inverter motors, this motor is controlled by analog signals, the control response is slow, inaccurate positioning, the general range of speed narrowing high-speed on the absence of low-speed or low-speed on the absence of high-speed and speed control is not accurate! Farrer Instruments tension machine motor used for the Japanese Panasonic all-digital AC servo motor, control mode using full digital pulse control, speed range, up to 0.001-1000MM/MIN, control and positioning accuracy, fast response, 0.01 seconds can be added to the full speed, the motor can ensure full-scale speed control is accurate and long service life of up to a few decades, and do not have to maintain.
5. Tensile testing machine / tensile machine accuracy of the key points of the measurement and control system motherboard Shanghai Ferry Instruments main controller using the 21st century's most advanced 32-bit ARM processor,
Processing speed to the level of Pentium-level general-purpose computers, compared to the traditional 8-bit MCU measurement and control system overall performance is greatly improved, the computing speed is faster, higher control accuracy.
Advanced speed, displacement, force three closed-loop technology, can realize precise arbitrary waveform control.
6. Tensile testing machine / tensile machine accuracy of the main points of the software FARI Instruments tensile machine measurement and control software powerful unit system, can adapt to any unit system in the world, such as the force value unit gf, kgf, N, kN, tf, lbf, ozf, tf (SI), tf (long), tf (short), etc. for choice, but also to expand any variety of units.
More protection mechanisms: force, travel, displacement over range protection settings, upper and lower limit travel switch hardware protection settings.
Adopting multi-threaded parallel processing technology, the test process real-time simultaneous display of force-displacement, force-time, displacement-time, stress-strain curves, etc., can be switched to the desired curve screen, and can view the user settings.
Fully open test result editing method, users can get any test result they want. Maximum force, breaking force, peeling force, tensile strength, shear strength, tear strength, maximum deformation, yield force, elongation, modulus of elasticity, ring stiffness, non-proportional elongation, minimum force in the interval, average force in the interval, fixed elongation to take the force, fixed force to take the elongation, and so on, up to more than 400 calculations by the computer automatically calculate the results for the user to choose to call.
Three, whether it is a real test machine manufacturers, which is the most direct impact on the price of the main reason, we recommend that customers must first go to the field before confirming the purchase.
