100-ton/1000KN Top-mounted Electro-hydraulic Servo Manhole Cover Pressure Testing Machine
Other Products
I. Main Purpose of the Equipment:
The microcomputer-controlled electro-hydraulic servo manhole cover pressure testing machine is mainly used for compression strength tests of manhole covers. Various test parameters are controlled, measured, and displayed by the computer, offering high integration and ease of use.
The microcomputer-controlled electro-hydraulic servo manhole cover pressure testing machine is specifically designed for compressive strength tests (load-bearing capacity tests) of sewer grates, cast iron manhole covers, steel fiber reinforced concrete manhole covers, water grate covers, and recycled resin composite manhole covers. The test methods comply with the requirements specified in standards such as:
CJ/T3012—93, JC/T889—2001, CJ/T121—2000,
CJ/T948-2005GB/T23858-2009《Manhole Covers》
CJ/T211-2005《Polymer Matrix Composite Manhole Covers》
CJ/T511-2017《Cast Iron Manhole Covers》
CJ/T1009-2006《Glass Fiber Reinforced Plastic Composite Manhole Covers》
CJ/T327-2010《Ductile Iron Composite Resin Manhole Covers》
CJ/T121-2000《Recycled Resin Composite Manhole Covers》
CJ/T130-2001《Recycled Resin Composite Water Grates》
CJ/T212-2005《Polymer Matrix Composite Water Grates》
CJ/T328-2010《Ductile Iron Composite Resin Water Grates》.
II. Main Structure and Functional Features:
The testing machine mainly consists of the main unit, oil source, control cabinet, and test force measurement and acquisition system. The main unit adopts a double-column frame structure, which is compact and easy to operate. The oil source uses a dedicated oil source for testing machines, with high system pressure, low noise, and stable performance. The measurement system primarily collects data through high-precision load sensors and residual deformation measurement devices. The computer displays test force and deformation, with functions such as zeroing, calibration, gain adjustment, and peak hold.
