Product features:
-
The system adopts plunger pump + frequency converter control to enable high-pressure regulation. A 15L/min pump is deployed for rapid pressurization, ensuring that the pressurization process for samples with a pipe diameter of φ400mm and a maximum length of 1000mm can be completed within 60~70 seconds.
-
The host system utilizes a centralized cluster control architecture based on embedded PCs. Each workstation functions as an independent module integrated with microcomputers, which receive control instructions from the embedded PC, execute pressure adjustment, logic processing, and data collection. Meanwhile, these modules continuously transmit control data back to the PC through a serial bus, enabling automatic identification of sample volume characteristics and material properties.
-
The exclusive pressure control system automatically formulates pressure-rising protocols and algorithms, guaranteeing rapid pressure rise, stable constant pressure, strong expansion capability, and a 100% test success rate. It comes with functionalities including real-time monitoring, data storage, power-off data protection, power-on data recovery, test result storage and printing, and sample pre-treatment.
-
High-precision pressure acquisition and control are achieved through the adoption of a vector frequency conversion system and high-precision pressure sensors. A fuzzy PID pressure control algorithm is employed to realize linear pressure rise until burst. High-precision pressure transmitters and subsequent conditioning circuits are utilized to achieve high-precision pressure acquisition.
-
Featuring ease of use and convenient operation, the instrument is equipped with an automatic pressure relief function (only one button is required for pressure release). Two time display modes (count-up and count-down) can be switched freely, and it also supports storing and printing test reports that include curves and test data.
