6.对8柱塞泵的测量模拟表明,当泵的合成轴向力是噪声发射的主要原因时,在8柱塞泵中,缸体工作腔内压力变化过程处于最优化条件下,其噪声可能降8dB(A).检验这一结论,目前只能通过实际的轴向柱塞机构,测量其噪声才能说明,因此批量的9柱塞泵在结构上要作适当的修改.为了在改变结构时将费用限制在最小的范围,批量泵的柱塞仍要利用.当柱塞面积模拟时选定流量Q_8=Q_9,那么理论的容积流量就会减
6. The simulation of 8-piston pump shows that when the pump’s synthetic axial force is the main reason of noise emission, in the 8-piston pump, the pressure change process in the working chamber of the cylinder is under the optimal conditions, and the noise May drop 8dB (A) .To test this conclusion, currently only through the actual axial piston mechanism to measure the noise to illustrate, so the bulk of the 9 piston pump in the structure to make the appropriate changes in order to change the structure When the cost is limited to a minimum range, the plunger of the mass pump is still used.When the piston area is simulated, the selected flow Q_8 = Q_9, then the theoretical volume flow will be reduced
