Instrument features

1. Manual loading
Combining domestic and foreign instruments, as well as the characteristics of our SWG, SWX, and SWY series strong strength machines, vertical loading is used in the sand strength test (most foreign products are vertical), completely overcoming the testing errors caused by static friction and self weight during the no-load process of the original horizontal machine;
During the low wet pressure and wet shear strength tests of green sand, vertical loading is used. Due to the low strength of the sand sample, it is not suitable to directly contact it with hands. It is better to use the SAC prototype equipped with a special opening and closing punch tube with a support plate for sample preparation, which is directly placed on the vertical loading platform to avoid damage to the sand sample during operation and affect the test results;
When conducting strength and compression tests (such as resin sand specimens), no other high-pressure accessories or pressure equipment are required.
2. Cross head fixture mechanism
This instrument uses a crosshead displacement adjuster, which facilitates the placement of test samples and reduces idle time. The application of the crosshead fixture system not only improves testing accuracy but also makes operation very convenient.
3. High precision
This instrument adopts CNC mechanical loading, which avoids measurement errors caused by changes in hydraulic oil viscosity due to leakage and temperature difference caused by hydraulic loading. The application of high-precision S-shaped force sensors and a 4/2 bit A/D data acquisition system can achieve fast data acquisition rate and truly reflect the peak data when the sample is damaged. Further improve the accuracy of the system.
4. Data storage and power failure protection function
This instrument can fully store the collected data in the computer system for further display and printing output in the event of shutdown or power outage.
5. Storage and printing function (optional)
The instrument has strong printing function. Capable of outputting collected and stored data in the form of data through keyboard commands. For two or more sets of data, the average value can be printed.
