Jinan, a professional production of new promise spring tension and compression testing machine

The test machine is a major achievement in scientific research and technology companies over the years. The machine according to JB / T7796-2005 "spring tension and compression testing machine technology" made the technical requirements. The model is mainly to do all kinds of coil spring tension and compression tests. Test force of the spring at a certain amount of displacement, or measuring deformation of the spring under certain test force, can also be used for other elastic components and small mechanical testing, mainly for spring factory, low-voltage electrical plants, power machinery factories, universities and research institutes. In the machinery manufacturing and a variety of devices, springs or elastic elements for good or bad part of the spring, the elastic component quality, it will affect the overall performance and service life of the machine according to the << spring tension and compression testing machine technical conditions >> The technical requirements made, mainly for the strength test coil springs and elastic components, namely a given amount of elastic deformation was measured elasticity. I. Features: 1. Dual Rail solve the measurement error and measurement error due to both ends of a compression spring machine stiffness caused by unbalanced surface caused by poor. 2. The use of new precision instrumentation amplifiers, precision, high-stability voltage reference and high-precision DACs, ensure the machine with high resolution and excellent repeatability. 3. Using a large area of ??the LCD as a display, real-time display force value, displacement, displaying information and intuitive full force value is stable; 2-3 can be accurate to one decimal place; displacement accurate to two decimal places 4. unique The automatic operation mode, the measurement of very simple multiple points, each work process can test for 12 points, each point measured without pause, without any time interval, greatly improving the work efficiency. 5. Machine reasonable layout, compact structure, optimize circuit design, with high robustness. 6. Overload limit protection can test print stiffness, force value, displacement, data can be set to automatically print or manual print.
