Product OverviewMitech MDW-S digital display series gantry landing type Spring Tension/Compression Testing Machine, through the single-chip automatic control motor driving screw movement, for a variety of coil springs for tensile and compression test. it use of built-in controller, AC servo motor, automatic control and data acquisition system, stable performance, strong structure, high reliability, simple operation, high degree of automation. Widely used in spring manufacturing, low-voltage electrical appliances, power machinery, institutions of higher learning and scientific research institutes and other fields.It is the necessary professional precision testing equipment for improving production efficiency and saving production costs.
Function & applicationWidely used in spring mechanical performance test.
Working PrincipleSpring tension/compression testing machine measured by the force generated by the sensor signal amplified by the A / D converter into the digital signal is accepted by the computer system, the digital processing, the computer system to deal with the operation of A / D conversion Signal to the LCD display data.
Working Conditionsl Operating temperature: room temperature ~ 45 ℃;
l Relative humidity: 20% to 80%;
l No vibration around, no corrosive media, no strong magnetic field interference;
l Horizontal installation on a solid basis;
Instrument Featuresl Widely used in spring manufacturing, low-voltage electrical appliances, power machinery, institutions of higher learning and
scientific research institutes and other fields;
l Modeling novel, strong structure, high reliability, simple operation, high precision measurement;
l The speed of the beam during the test can be pre-set by the program or seeting by manual;
l Built-in controller to ensure that the test machine can be specimen deformation, test force and displacement of the closed-
loop control;
l All-digital AC servo motor through the no noise synchronous toothed belt, high precision seamless ball screw drive to ensure
its smooth load, no gap, high transmission efficiency;
l 5000-line optoelectronic encoder, the relative high accuracy of displacement;
l High precision and high stability of the tire tension and compression strain sensor, coupled with high-precision measurement
and amplification system to ensure that the test force of high precision;
l With a limit protection function, arrived at the limit after the automatic shutdown, to prevent the collision in the middle of the
beam caused by overload or even damage to the sensor;
l With overload protection function, when the load exceeds the maximum value of 3-5% of the file, the test machine
automatically shut down;
l Automatically according to the size of the load can be switched to the appropriate range to ensure the accuracy of
measurement data;
l Zero adjustment, calibration, storage, etc. without any analog adjustment link, the control circuit is highly integrated;
l Test end, test data and test curve automatically saved for later retrieval analysis;
l Use of LCD display, menu-type user interface, simple and intuitive, convenient and quick;
l Consitent with GB, ISO, ASTM, DIN and other relevant domestic and foreign standards.
Operating Method and AttentionsInstrument Maintenancel Before using this instrument, please read the instruction manual carefully, understand the operation steps and precautions,
avoid the damage caused by improper operation or personal safety accident;
l Test machine is a large precision instruments, should pay attention to water, moisture. Exposed workstations, upper and
lower beam parts and attached parts should be coated with anti-rust oil to prevent rust;
l If idle for a long time, at least once a week and move the upper and lower beams, so that beam position, silk mother often
activities to prevent rust;
l The instrument should be test at least once a year to ensure the accuracy of the test machine;
l Electrical connection cable and equipment should be careful when connected, moderate efforts, remember not to swipe,
hard pull.
l Don’t disassemble the instrument without authorization, maintenance related matter, please contact MITECH after-sale
service department with 4000600280.
