The manhole cover pressure tester adopts a hydraulic loading system and manually controls the loading; the manhole cover pressure tester controller realizes electronic force measurement and digital display. As the name suggests, the manhole cover pressure tester is a equipment that tests manhole covers. So how much do you know about this equipment? Let’s introduce the characteristics and working conditions of the manhole cover pressure tester to you, hoping to help you understand more.
1. Equipment characteristics of manhole cover pressure tester:
1. Use a microcomputer to display, drive the hydraulic cylinder and load sensor to detect the test force of the test piece. Stable and reliable performance, accurate data detection.
2. This test machine is suitable for test pieces with a bearing capacity of more than 20kN and no more than 1000kN.
3. Comply with the national GT/T2611 "General Technical Conditions of Test Machines" and the national metrological verification regulations JJG139 "Tenering, Pressure and Universal Test Machines".
4. The manhole cover pressure tester is suitable for compression and bending strength tests of manhole covers, and can meet relevant professional standards such as 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 related professional standards.
5. The host adopts a high-rigid structure to ensure safety during the test.
6. Place the loading cylinder on the top, and the workbench height is 300mm, which is easy to pick up and put up the manhole cover specimen.
7. A ball-hinged connection is adopted between the rigid pad and the piston push end to ensure the authenticity of the measured bearing capacity.
8. The oil cylinder and piston of the manhole cover pressure tester are sealed with special materials to achieve high sealing, low friction and long life.
9. Use professional test oil pump motor set, low noise and long life.
10. Choose an ultra-fine oil filter to ensure the cleaning of the oil circuit system and ensure the long-term work of the control actuators.
11. The digital display table displays the current force value, peak value, etc. in real time.
2. Working conditions of manhole cover pressure tester
1. Within the range of room temperature of 10℃-35℃, the relative humidity shall not exceed 80%;
2. Install correctly on a stable basis, with a level of 1/1000;
3. In a vibration-free environment, there is no corrosive medium or electromagnetic field interference around it;
4. The fluctuation range of the power supply voltage should not exceed ±10% of the rated voltage;
5. The mechanical and electrical control cabinet of manhole cover pressure test should achieve reliable grounding.
To sum up, it is the characteristics and working conditions of the manhole cover pressure tester. In the process of selection, users can choose based on their own situation.
