دستگاه تست ضربه سری میکروکنترل Mitech MJB-W، از طریق کنترل کامپیوتری حرکت آونگ ، برای فلز، که می تواند فلز، مواد غیر فلزی و کامپوزیت تحت مقاومت بار دینامیکی در برابر ضربه تست باشد استفاده می شود. از کنترل کامپیوتر، با عملکرد پایدار و درجه بالایی از اتوماسیون، استفاده می کند. عملکرد یکپارچه. ساختار آن قوی، ساختار ساده، راندمان بالا است. این دستگاه به طور گسترده ای در فولاد، لوله های فولادی و دیگر فلزات آهنی و آلیاژهای آن استفاده می شود که از عملکرد ضربه ضد آونگ آن برای اندازه گیری دقیق استفاده می شود. تجهیزات تست دقیق حرفه ای لازم برای بهبود راندمان تولید و صرفه جویی در هزینه های تولید است.
Function & application
It is widely used in the accurate determination of pendulum impact resistance of ferrous metals and alloy materials, such as steel, steel pipe, etc..
Working Principle
The hemispherical punches of the impact testing machine impact and pass through the specimen at a certain speed and measure the energy consumed by the punch to evaluate the impact resistance of the specimen.
Working Conditions
l Operation Temperature:Ambient temperature～45℃；
l Relative humidity:20％～80％；
l In an environment free from vibration,corrosive medium and high magnetic field
l Installed on a flat basis.
l Power supply voltage fluctuation does not exceed 10% of rated voltage.
Instrument Features
l Widely used in metallic and non-metallic processing industry, quality testing in quality inspection departments , scientific
research in higher education institutions and other fields;
l It adopts single-chip control,and tilt pendulum, hanging pendulum, impact, are all under the computer control, and automatic
tilt pendulum, with high efficiency, especially for continuous impact test;
l Zero adjustment, calibration, save, etc. without any analog adjustment link, the control circuit is highly integrated;
l The system can realize the automatic calibration of the indication accuracy;
l At the end of the test, the test data is automatically saved for later retrieval.
l With features of novel shape, strong structure, high reliability, simple operation;
l Can be directly observed in the display, intuitive readings, high test efficiency;
l Using a single support column structure, cantilevered hanging pendulum, U-shaped pendulum hammer, with stable
performance and high precision;
l Impact knife with screw mounting fixed, easy to replace;
l Sample simple beam support can quickly replace the sample, easy to operate;
l Take the brand computer, Chinese and English Windows operating platform, menu prompts, mouse operation, with fast
running, clear interface, simple operation and so on, to meet the needs of different materials test;
l Real-time print output test data, user-friendly data processing, analysis and so on;
l Equipped with safety protection pin, safety protection network, etc., to ensure safety test;
l Consistent with GB, ISO, ASTM, DIN and other relevant domestic and foreign standards.
Operating Method and Attentions
Instrument Maintenance
l Before using the instrument, please read the instruction manual carefully, understand the operation steps and precautions,to
avoid the damage caused by improper operation or personal safety accident;
l Testing machine is a large precision instrument, should pay attention to avoid water, moisture. Exposed workbench and
attached parts should be coated with anti-rust oil to prevent rust;
l It is forbidden to put samples before the pendulum hangs. Before placing the sample, make sure that the pendulum has been
stalled and that the insurance pin has been ejected;
l Should pay attention to check the use of jaw support, pendulum, etc. are reliable to live tight to prevent the test results
inaccurate or accident occurred;
l Pendulum shaft bearings at both ends of the factory has been refueling, users do not have to refuel, if it is repaired,then add
1-2 drops of sewing machine oil or watch oil, the rest of the power bearing plus Vaseline or butter;
l If idle for a long time, at least once a week to prevent rust;
l After the test, the pendulum to be placed in the vertical position, and the handle putter placed in the brake position.
