Study On The Saving-energy Principle Of Oscillation Sieve

In engineering applications,because the service medium hasn't absorbed all vibration energy of vibration machine,there is a energy-wasting problem. Aimed at the energy-wasting problem in the vibration machine, according to the character that vibration and impact machine consume the most power in the start moment and receive potential force, at the time of asking for the power equation, separated the potential force from the machine system, researched the energy-saving effect combining with the effect of potential force. Introduced a new principle of machine energy-saving design, based on the potential energy as a constant. The principle indicates if there are potential forces in the vibration machine, making the potential force be a balance system can reach the purpose of saving energy, at the same time came to the conclusion that vibration energy can't be fully absorbed by service medium,the energy-wasting is not only related with the movement form of vibration machine but also excitation form and the vibration of the work.The productivity and the screening quality had seriously affected the highway's rate of progress and the construction quality, Vibration sieve also had the energy-wasting problem. After proving the validity of machine energy-saving design, applied the principle in vibration sieve in order to resolve the energy wasting problem. Made vibration exciters to be a balance system of potential force, satisfied the condition potential energy to be constant to design the oscillation sieve. Changed the output of vibration exciter from force to moment, at the same time changed the movement form of vibration sieve from vibration to oscillation. The conclusion that oscillation sieve is better than vibration sieve in the effect of saving-energy by analyzing the testing vibration sieve can be gained.By theory analyzing and testing, the energy-saving technology can be realized which need to be satisfied vibration exciter to be a balance system of potential energy,the equipment to be a balance system of potential energy and the rate of kinetic energy to be the least.
