Product Description

Lift traction machine load test system, inverter performance online test bench

Traction machine test system

The power part of the traditional elevator is mainly composed of a traction machine, a frequency converter, a car, a wire rope, and a counterweight. The traction machine adjusts the balance of the car and the counterweight by rolling the wire rope to realize the control of the height of the car, that is, the elevator goes up and down. Its product development and factory testing of the traction machine must ensure product performance and product quality, so it is particularly important to conduct strict testing and analysis of the performance of the traction machine.
 

The traction machine test system adopts a modular, integrated design, and the operation part is ergonomically designed, and can complete manual/automatic mode control. The bench is divided into a single traction machine test bench and a double traction machine towing test bench, which is mainly composed of three parts: mechanical system, electrical system and upper computer software system.
1.Mechanical system: mechanical platform, loading equipment (electric dynamometer/traction machine), clamping system, shafting connection part and other equipment.
2.Electrical system: drive controller, load control, sensor (torque, speed, current, voltage, vibration, temperature) real-time data acquisition system, data acquisition, current sensor acquisition, electrical parameter measurement equipment, alarm system and other equipment.
3.Software system: The upper computer test software is divided into data acquisition communication module, data acquisition setting module, data real-time exchange control module, and data processing module according to the system. The host computer completes the functions of test control, data analysis and display, data recording and export according to the test items.
Test items: input current, voltage, power factor, electric power, output torque, speed, power, efficiency, temperature rise, vibration and noise, etc. The traction machine test system is suitable for completing the whole performance test in the process of simulating the actual operation conditions of the traction machine→ that is, forward start upward → braking→ reverse start→ downward → braking. The system mainly completes the test of torque, rotation speed and so on. And complete the data collection, storage, report, curve drawing and printing functions. It is to complete the factory test and development performance test of the traction machine. The main test process is that when going up, the traction machine runs as a forward motor, while when going down, the traction machine runs as a generator in reverse. In order to be able to simulate the actual operating conditions of the traction machine, such as forward and electric upward and reverse power generation downward, the load must be able to drive/load in four quadrants (generator/motor, forward/reverse). The speed is operated between 0 and steady speed throughout the operation, but a constant test load is required.

Key features:
1.All bench building functions are modular, and test modules can be added or decreased according to the different test objects.
2.The advanced real-time measurement and control system meets the requirements of high precision and fast response of the test system, and is convenient for the software to conduct a comprehensive analysis of the test process data in the later stage.
3.According to the test requirements specified in the national standard, the test items can be increased or decreased according to the configuration module to meet the test items of various types of tests.
4.The asynchronous motor/permanent magnet motor/traction machine is used as the load of the tested motor, which changes the traditional load mode, improves the dynamic measurement range and accuracy of the system's torque and speed, improves the loading performance (forward/reverse, reverse drag), and shortens the response time of loading.
5.Professional motor test bench, fixture with quick docking function, easy to load and unload, can adapt to the installation of different tested motors, the system operation adopts piano table/cabinet + computer table control mode, can complete all test operation layout in a single position.
6.Customized test software, classifying the software interface and process, reducing repeated tests, and greatly improving the work efficiency of testers. It can be used for real-time curve drawing, transient value capture, trend curve drawing and analysis, multi-parameter combination display, pass judgment, and report export.
