Analysis and Treatment of Low Control Oil Pressure of FW Pump Turbine in 1000MW Unit
Power System Engineering, 2020Co-Authors: Liu Zhi-qianAbstract:Two AC motor Oil pumps,which are the parts of the A feedwater pump turbine Oil system of No.8 unit in Huadian Zouxian Power Generation Co.,Ltd.,had been cooperating due to the low Control Oil Pressure.Because of the lost of backup,the safety and stability operation of the unit was influenced seriously.Through analysis and investigation,the cause of the low Control Oil Pressure was confirmed to be the large inner leakage amount of the relief valve.The defect of low Control Oil Pressure was solved completely after the equipment treatment.

Comparative Study of the Auto Electronic Control System
Applied Mechanics and Materials, 2014Co-Authors: Feng Zhen Qu, Bao Cheng LuAbstract:Based on mathematical principle of function interpolation we design dominant and recessive auto electronic Control system. In order to compare the performance of the two systems, we design a Control experiment of automobile electronic signals for these two systems. The system adopts the CAN bus Control, the wheel speed and door signal use the 0001-0100 signal channel to Control, Oil Pressure and fault signal use the 0100-1111 signal channel to Control. From the testing results of two systems, the dominant auto electronic Control system occupies 8 channels, which is far from the theoretical value; and the recessive Control occupies only 2 channels, which is accord with the theoretical value. It provides the technical support for the design of automotive electronic Control system

Stability of Oil Film and Output Speed of Hydroviscous Drive Affected by the Pressure of Control Oil
2020Co-Authors: Huang XiaoAbstract:Based on the theories of hydraulics and nonlinear Control system, the model of hydroviscous drive (HVD) was established, the influences of small ripple of Control Oil Pressure on the output speed of HVD and the stability of Oil film between friction disks were analyzed. The conclusion presents that when the frequency of the Control Oil's Pressure ripple is higher than 60?Hz and the peak is less than 0 05?MPa, HVD can work stably. The result is useful for studying the application of frequency conversion technology in regulation of Control Oil Pressure.
