As shown in FIG. 10 and FIG. 11, it is the operation mode of the above-mentioned conventional five-pressure chamber diaphragm pump. When the output shaft 11 of the motor 10 rotates, the tilting eccentric cam 40 is rotated, and at the same time, the balance wheel housing 50 is The five balance wheels 52 sequentially generate up and down reciprocating motions, and the five piston actuating regions 74 on the diaphragm 70 are also actuated by the up and down movements of the five balance wheels 52, and the synchronization is pushed up and down. The reverse up and down displacement, therefore, when the balance 52 is actuated downward, the piston actuation zone 74 and the piston pusher block 80 of the diaphragm 70 are simultaneously pulled down, so that the piston piece 98 of the piston valve body 90 is pushed away and will come from the pump.

As shown in FIG. 12 to FIG. 14, the conventional five-pressure diaphragm diaphragm pump has a serious defect for a long time. When it is actuated, the five balance wheels 52 will alternately push up the piston actuation region 74 of the diaphragm 70. It is equal to the position of the five piston actuating regions 74 on the bottom surface of the diaphragm 70, and an upward force F (shown in FIG. 13) is continuously applied, and the external force 71 and the positioning convex are multiplied by the force F. The torque generated by the arm length L1 between the ring blocks 76 (ie, the torque = F × L1) causes the entire pump body to vibrate. Since the motor 10 output shaft 11 rotates at a speed of 800-1200 rpm, it drives five The intensity of the 〝 vibration generated by the rotation of the balance wheel 52 has been high.

The effect of the cushion 102 to achieve the shock absorption is rather limited, and the strength of the shock generated by the pump body is extremely strong, and the sound of the outer casing C is still generated to cause an annoying sound. Further, the water pipe connected to the water outlet 22 of the pump head cover 20 is provided. P will also oscillate synchronously with the frequency of the 〝 ( (Figure 14 and its The imaginary line P in the a view) is slapped to other components in the adjacent reverse osmosis water purifier. If it is used for a period of time, the water pipe P and its pipe joints will gradually loosen each other due to swaying. In the end, it will lead to the result of water leakage. Many of the above defects are caused by the 〝 vibration caused by the operation of the five plenum diaphragm pump. Therefore, how to greatly reduce the 〝 vibration loss caused by the operation of the five plenum diaphragm pump has been It has become a very urgent issue to be solved.
