Detailed description
I. Product Introduction
The DYJ-1000S computer-controlled automatic manhole cover pressure testing machine is a high-precision material testing equipment driven by a hydraulic power source, utilizing electro-hydraulic servo control technology, and computer data acquisition and processing. It can achieve closed-loop control and automatic detection. It consists of four parts: the main testing machine, oil source (hydraulic power source), measurement and control system, and testing fixtures. The maximum test force is 1000kN, and the accuracy grade of the testing machine is 1st grade.
The DYJ-1000S computer-controlled automatic manhole cover pressure testing machine is used for bearing capacity (residual deformation and test load) tests of manhole covers made of various materials. It can achieve closed-loop control such as equal-rate loading and equal-rate deformation, and can automatically obtain the technical indicators of the test pieces.
This testing machine and its accessories comply with the following standard requirements:
GB/T23858-2009 "Manhole Covers"
GB/T26537-2011 "Steel Fiber Reinforced Concrete Manhole Covers"
CJ/T211-2005 "Polymer Matrix Composite Manhole Covers"
CJ/T121—2000 "Recycled Resin Composite Manhole Covers"
