NT4000 - Mining shearer/scraper test system - Main features
01 Functional Modularization
The whole design of the platform is adopted, and the modular component combination is adopted inside, which is convenient for the platform combination and maintenance.
02 Advanced means of measurement
Advanced real-time measurement and control system is adopted, including input electrical parameters test, rotational speed torque test, etc. The sampling rate of torque and rotational speed is up to 1000Hz, which meets the requirements of high precision and rapid response of the test system. Moreover, transient data and eigenvalue data are provided to facilitate the comprehensive analysis of test process data by software in the later stage.
The test items are complete
According to the test requirements stipulated by the national standard, the test items can be added or subtracted according to the configuration module, which can meet various type verification test items
04 System Design
It adopts advanced CAN fieldbus design, conforms to the international standard ISO11898(CAN), and has simplified network characteristics. Multiple test systems CAN be connected to the network, and the function expansion of the system does not need to be rewired, but CAN be connected to the bus module nearby. I/O channel can be expanded and adjusted at will to adapt to a variety of complex and changeable site. Digital calibration technology is adopted to make the calibration simple, fast, highly intelligent, rich in self-check, prompt, and parameter setting functions. Modular design simplifies the structure, improves reliability and maintainability.
05 Humanized design
Adopt professional bench design, fixture has quick docking function, and convenient loading and unloading can be adapted to different specimen installation.
Customized test software
The test system test software developed by Sichuan Chengbang software development team designs the software according to the test process, categorizes the software interface and control process, reduces the repetition of tests, and greatly improves the work efficiency of the test personnel. It also has the functions of real-time curve drawing, transient value capture, trend curve drawing and analysis, multi-parameter combination display, qualification determination, report export and so on.
