The pressure testing machine is a testing machine suitable for all kinds of compressive loading. It can be used to test the compressive strength and elastic modulus of various engineering building materials such as high-strength concrete, cement components, rock and so on. The accuracy error of test force indication is ≤± 1%, which has the characteristics of good rigidity, high precision, simplicity and ease of use.

1. It adopts fixed frame structure with high rigidity.

2. C3 level high-precision spoke load cell is adopted, which is not affected by air temperature, with high precision, good stability and good output linearity.

3. The suspended large-diameter spherical seat is designed with advanced grinding technology. The spherical roughness reaches Ra0.2 microns and the surface coincidence is more than 95%.

4. High performance two-way oil cylinder is adopted, with fast oil return speed, zero leakage, good repeatability and linearity.

5. The test space is large, and the spacing between the upper and lower pressure plates is 90-340mm, which is convenient for test expansion, verification and calibration.

6. The imported high-pressure plunger pump and differential pressure Follow-up Technology of oil source system are adopted, with lower noise and better control of hydraulic oil temperature rise, so as to ensure that the temperature of hydraulic oil is normal under the normal working condition of 24 hours a day. It has 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 plastic spraying process, which is wear-resistant, dirt resistant and easy to clean.

9. The force measuring cabinet adopts a novel embedded design, which can withstand a voltage range of 85-250v and has stronger anti-interference performance.

10. The dual control mode of touch screen and keyboard is adopted, which has a neat and beautiful appearance and meets the preferences of different technicians.

11. Microcomputer automatic data acquisition and processing and synchronous screen display of test data and test curve are adopted.

12. The test curve can be locally enlarged and the superposition comparison of multiple curves can be carried out.
