Product use:
The pressure testing machine is a kind of testing machine suitable for all kinds of compression loading, which can be used to test the compressive strength and elastic modulus of various high-strength concrete, cement components, rocks and other engineering building materials. The accuracy error of the test force indication is less than ± 0.5%, which is characterized by good rigidity, high precision, simple and easy to use.
Main features:
1. Adopt four columns and fixed beam structure, with high rigidity.
2. C3 class high-precision spoke type weighing sensor is adopted, which is not affected by air temperature, with high precision, good stability and good output linearity.
3. The design of the hanging big straight street ball surface seat adopts the advanced grinding technology. The surface roughness reaches 0.2 μ m, and the surface coincidence reaches over 95%.
4. High performance two-way oil cylinder, fast oil return, zero leakage, good repeatability and linearity.
5. The test space is large, and the distance between upper and lower pressure plates is 115-450mm, which is convenient for test expansion, verification and calibration.
6. The imported silent internal gear pump and oil source system pressure difference follow-up technology are adopted to reduce the noise and control the temperature rise of hydraulic oil better, so as to ensure that the temperature of hydraulic oil is normal under normal working conditions 24 hours a day, with the advantages of small volume, light weight and stable performance.
7. It has rich fixture tooling, deformation measurement and other accessories, which can meet various needs of customers.
8. The paint of the whole machine adopts spray molding technology, which is wear-resistant, dirt resistant and easy to clean.
9. The force measuring cabinet adopts a novel embedded design, which can bear a voltage range of 85-250v and has stronger anti-interference performance.
10. It adopts touch screen and keyboard dual control mode, with neat and beautiful appearance, meeting the preferences of different technicians.
11. By using Windows system control software, the elastic modulus E, upper yield strength Reh, lower yield strength rel, specified plastic extension strength RP, tensile strength RM, specified total extension strength RT, yield point elongation AE and other technical parameters can be obtained automatically.
12. The microcomputer is used for automatic data acquisition and processing as well as synchronous screen display of test data and test curve.
13. The test curve can be locally enlarged and multi curve superposition comparison can be carried out.
14. The test software supports the simultaneous control of compression and bending resistance of the testing machine, which can greatly provide the use efficiency of the equipment.
