Product Details
Negative pressure test machine of the plastic inspection well
Summary:
The system is mainly used for anti-voltage stability test, negative
pressure test and sealing performance test. Plastic inspection well
anti-pressure instability (negative pressure) test is used to test
the ability to resist groundwater mainly external load after the
burial of the plastic inspection well base. Seal the head of the
specimen and place two sets of deformation measuring devices on
both sides of the flow groove and the bottom of the flow groove,
then subject the specimen to a stable internal negative pressure
and maintain above 1,000h. Record the deformation amount of the
flow groove with time, observe the sample deformation, collapse,
crack or silver pattern in the test, and extrapolate the
deformation amount of the well base for 50 years.Check the negative
pressure test and sealing performance of the well for the
resistance to negative pressure and the sealing of the system.
Product characteristics:
- The test pressure is arbitrarily set from-80kPa~0kPa, and the
efficient vacuum system can quickly draw the sample to the set
pressure;
- The measurement sensor can be freely adjusted and locked in
multiple directions for testing requirements from 315mm~1200mm; To
ensure that the specimen can be used normally under improper
placement or strengthening rib on the specimen surface;
- The application of industrial embedded system and large full color
LCD touch screen realize the long-term uninterrupted automatic
monitoring of the test process, and automatically record the
pressure-time, deformation-time curve in the test process;
- USB interface settings for data export via the U disk;
- The system has the function of power loss protection, and there is
no need to worry about the loss of the test data due to accidental
power failure. If the power failure is abnormal in the test, after
the test start again reaches the set pressure, the system will
automatically postpone the timing.
- Equipped with PC machine data management software.
