Microcomputer controlled electro-hydraulic servo manhole cover pressure testing machine

The main engine of the microcomputer-controlled manhole cover pressure testing machine adopts a high-rigidity structure to ensure safety during the test process. It uses an ultra-fine oil filter to ensure the cleanliness of the oil circuit system and ensure the long-term operation of the control actuators.According to GB/T 23858-2009 "Inspection Manhole Cover", GB/T26537-2011 "Steel Fiber Concrete Inspection Manhole Cover", CJ/T3012-1993 "Cast Iron Inspection Manhole Cover", CJ/T121-2000 "Recycled Resin Composite Inspection Manhole Cover" and JC889-2001 "Steel Fiber Concrete Inspection Manhole Cover" and other industry or national standards are designed and produced for testing the bearing capacity of manhole covers.Its structural performance fully complies with the test specification requirements.It can be programmed by the user on site according to the experimental needs, with automatic closed-loop control, cyclic loading, loading speed, and loading waveform (because the loading process stipulated in the standard is a cyclic waveform loading process). In short, each index step of the national standard can be programmed, making the entire process fully automated without manual intervention.
