電機(jī)控制系統(tǒng)改進(jìn)設(shè)計與液壓泵性能試驗
[Abstract]:In order to complete the basic research on the performance test of hydraulic power components based on series-parallel hydraulic compensation power recovery principle, this paper has a detailed understanding of the relevant test standards and the experimental conditions that can be provided by the laboratory. Two main tasks are accomplished: 1, analyzing, improving and perfecting the electronic control part of the existing test system; 2, completing the performance test of the series pump and the parallel pump in the power recovery system. There are some problems in the electronic control part of the existing test system in the laboratory, such as the frequency conversion and speed regulation of the motor can not be realized, the design of the Y / start control circuit of the motor is cumbersome and the reliability is low. In this paper, the main circuit and control loop of the original motor control system are analyzed, the problem is found out, and the improved design is completed. The experimental results verify the correctness of the design. On this basis, the performance test of series pump and parallel pump in power recovery system is completed in this paper, which provides technical support for the performance test of hydraulic power components based on series-parallel hydraulic compensation power recovery principle.
