suction pump
3.On the basis of 3D modeling and virtual prototyping technology and energy saving transformation method for parameterized simulation moving beam typed oil suction pump, and using the eccentric gear reducer to replace the ordinary gear reducer to let the driving radius of eccentric gear be kept a variation of similar tendency with the load of crank in order to improve load property of the motor, thus raised the working efficiency of the entire oil suction pump and achieved the effect of energy saving.
4.Results showed that the best extracted design was: the baked green tea was sifted through a 0.45 mm sieve, the 3 g of sample tea were infused by 400 ml boiling deionized water, and extracted in boiling water bath for 30 min and then the extraction was sucked with suction pump and settled to the volume of 500 ml. The FAA contents were determined by the ninhydrin colorimetric method.
