The shield machine air automatic pressure-holding test system is a special equipment designed and developed by our company for the calibration, performance test and evaluation of the shield machine’s air automatic pressure-holding system and key components. Its main functions are as follows:
①Simulate the actual working status of the automatic air pressure holding system of the shield machine, observe the changes of various related parameters, and analyze the law of change.
②Verify the design scheme of the automatic air pressure holding system of the shield machine, and provide data support for the design and development of the system.
③Individual calibration and calibration of each core component.
④ Conduct comparative tests on the core components of the pressure holding system to provide experimental data for system optimization and analysis.
⑤ Carry out the step response of the system (static performance test), and evaluate the static operating characteristics of the system.
⑥ Carry out disturbance test (dynamic performance test) by adding disturbance to the system to evaluate the dynamic performance of the system.
