Upgraded Full Automatic Electrical Consolidation Apparatus
Lever consolidation instrument and pneumatic consolidation instrument are the two most commonly used consolidation test equipments in China at present. We all understand the shortcomings of lever consolidation instrument, while the disadvantage of pneumatic consolidation instrument is the test of dozens of consolidation instruments The pressure sequence must be the same. All samples can be compressed and stabilized before applying the lower load or ending the test. The test period is relatively long, which affects the equipment utilization rate. It cannot be controlled independently for each channel. In addition, the pre-pressure of 1KPa is actually controlled because of friction. No, even the 12.5KPa force cannot be controlled within 1% accuracy, which is estimated by the software. There are also such systems. First, they must be equipped with auxiliary equipment such as air pumps, air pressure stabilizing filter devices, air pressure networks, etc., and must be installed and debugged by professional and technical personnel on site before they are put into use; Affect the accuracy of the test results.
In summary, in response to the shortcomings of the pneumatic consolidation system, we have developed the third-generation fully automatic consolidation instrument to completely improve the above shortcomings.
Features:
1. This technology enables the consolidation test to automatically load and unload according to the set test pressure sequence without external pressure source (such as an air pump), saving energy and protecting the environment. Test pressure ≥ 5kPa ≤ the highest pressure allowed, the pressure sequence can be set arbitrarily within the most important pressure range, especially to meet the test that requires the application of the sample's own weight pressure P0. Each test process is independently controlled. The sample can be replaced and restarted after the test, which greatly improves the equipment utilization rate. During the test, the set pressure added by the variable speed tracking control is automatically based on the compression change of each sample, and the sample is always balanced. The initial value of the consolidation test, which is the zero displacement value of 1kPa, is also guaranteed to be true and effective. If the test of applying the self-weight pressure P0 is carried out, the P0 pressure to be applied for each sample can be set, and it can be applied at one time or applied in stages. This is impossible with any previous consolidation instrument.
2. With the microcomputer network
Using network port to connect with the microcomputer, dozens of consolidation instruments can be connected on the same network. The on-site installation is very simple. The microcomputer provides a single control and dozens of group control operations, which is very simple.
3. Independent operation and self-start
The consolidation controller can be operated independently, that is, no microcomputer support is needed after the test starts. Automatically protect the test site and the collected data when the power is cut off during the test process, and automatically resume the test site after the power is restored.
