The Static-Dynamic Characteristic Experimental Research And Its Application Of The Electromagnetic Valve Relieving Constant Pressure Variable Pump

The saving of the energy resources demands immediate attention nowadays, especially in the department of the energy utilization, because the consumption speed of the energy resources is going faster and faster, and the energy-saving conception is becoming more and more important. An energy-saving research has been done in this article on Q*DPCY type pump which is a kind of new type hydraulic pump invented by professor Xu Sheng-wu, a famous hydraulic expert. This new type pump has several features such as original, portable, low noises and energy-saving.A experiment research has been done on the original pump, Q63DPCY14-1Bk type constant pressure pump, using the synthetically experimental table which is built importantly by the institution. The principle analysis, experimental table construction and the data acquisition are included. Then the efficiency and static-dynamic characteristic analysis was done according to the data. After that a mathematics model was constructed by the method of transfer function and a simulation was proceeded on the model using the MATLAB/SIMULINK module, a contrast was done on the data collected by the experiment and the simulation, and then an optimized design was done by changing the construct parameters of the pump according to the result of the analysis. The optimized pump was applied on the design of the mountain drilling machine because of its advances on the energy-saving.
