The JAW-1000 microcomputer controlled manhole cover pressure testing machine is mainly used for compressive strength testing of manhole covers. This testing machine adopts advanced technologies such as servo motors with a wide speed range and computer digital control, which can automatically and accurately measure and control the entire testing process of the testing machine, including loading and unloading. Various experimental parameters are controlled, measured, displayed, processed, and printed by computers, with high integration and easy use.
The YAW-1000J microcomputer controlled electro-hydraulic servo pressure testing machine is specifically designed for conducting compressive strength tests (bearing capacity tests) on sewer grates, cast iron manhole covers, steel fiber reinforced concrete manhole covers, recycled resin composite manhole covers, etc. The test method meets the test requirements specified in standards such as CJ/T3012, JC/T889, CJ/T121, CJ/T948, etc.
Advantages and safety protection devices
1. Low noise, below 50 decibels under working load, basically in a silent state.
2. Pressure follow-up is 70% more energy-efficient than conventional equipment.
3. High control accuracy, with a control accuracy of up to one ten thousandth. (Usually 0.5%)
4. No control dead zone, with a starting point of up to 1%.
5. The oil circuit is highly integrated with few leakage points.
6. When the test force exceeds 2% -5% of the test force for each level, overload protection is activated and the machine is stopped.
7. When the piston rises to the upper limit position, the stroke protection stops and the oil pump motor stops.
8. Hydraulic oil system overload, overpressure, overheating, and overflow protection.
9. Automatic shutdown protection upon completion of the experiment.
