 Tester){kind=small}
It is used to test the plastic manholes resistance to external load, mainly water, when the manholes based was placed under ground. It’s a necessary equipment to evaluate the material properties of plastic manholes bases and structural integrity. This instrument complies with the following international and industry standards. BS: BS EN 13598-2. Test pressure from -70kPa ~ 0kPa arbitrarily set, efficient vacuum system can quickly pump the sample to set the pressure. Special sealed head, can be wrapped around the structure of the wall pipe, double-walled hollow wall pipe and double-wall corrugated pipe composed of the nozzle tube nozzle radial seal, easy to operate, reasonable head structure can be assembled once sealed, the user Can be customized a variety of sealed head;. cantilevered lifting structure design, deformation measuring device fixed to the cantilever end, was fan-like distribution, and can be telescopic adjustment, the structure of the test has an open test space for a variety of specifications from Φ315mm ~ Φ1200mm check wells test needs. Measurement sensor can be multi-directional adjustment and locking, to ensure that the specimen in the improper placement or the presence of stiffeners on the surface of the case can be used normally. Adopt industrial embedded systems, large-size full-color LCD touch screen, to achieve the test process of long-term uninterrupted automatic monitoring, without manual duty, automatic recording test process pressure - time, deformation - time curve; Detection, once the sample leakage or instability, the system automatically stops the vacuum pump operation, and prompted the test to complete. USB interface settings, through the U disk can be data export;. system witha power-down protection, no need to worry about the test data due to an unexpected power failure, if the test abnormal power failure, start the test again to set the pressure, the system automatically delay timing.
