10 and 11 are diagrams illustrating practical modes of operation of the conventional pumping diaphragm pump of FIGS.

Initially, when the motor 10 is turned on, the wobble plate 40 is driven to rotate by the motor output shaft 11, and the three eccentric circular members 52 of the eccentric circular mounting portion 50 continuously perform up and down reciprocating stroke operations. Do.

Second, the three pump pistons 80 and the three piston operating zones 74 of the diaphragm membrane 70 are continuously driven by the up and down reciprocating strokes of the three eccentric circular members 52, and displaced up and down.

Third, when the eccentric circular member 52 is stroked downward and the pump piston 80 and the piston operating zone 74 are displaced downward, the piston disk 98 of the piston valve assembly 90 is pushed and opened. Tap water W can flow into the pre-hydraulic chamber 26 through the water inlet orifice 21 of the pump head cover 20 and the inlet port 97 of the piston valve assembly 90 (the arrow extending from W in the enlarged view of FIG. 10). reference).

Fourth, when the eccentric circular member 52 is stroked upward and the pump piston 80 and the piston operating zone 74 are displaced downward, the piston disk 96 of the piston valve assembly 90 is pulled and closed. Then, the tap water W in the preliminary water pressure chamber 26 is compressed, and the water pressure in the inside is raised to the range of 80 to 100 psi. The pressurized water Wp that has received the pressure pushes the plastic anti-return valve 94 of the piston valve assembly 90 into an open state.

Fifth, when the plastic anti-return valve 94 of the piston valve assembly 90 is pushed into the open state, the pressurized water Wp in the pre-hydraulic chamber 26 is connected to the group of outlet ports 95 in the corresponding sector in the central outlet fitting 92. Via, it is directed to the high-pressure water chamber 27 and discharged from the water outlet orifice 22 of the pump head cover 20 (see arrow WP in FIG. 11).

Finally, by regular repetitive operation of each group of outlet ports 95 of the three sectors of the central outlet mounting portion 92, the pressurized water Wp is further filtered by a reverse osmosis membrane cartridge from a conventional pumping diaphragm pump. Thus, the finally filtered pressurized water Wp can be used in the reverse osmosis membrane water purifier.

FIGS. 12 to 14 show serious drawbacks due to the vibration applied to the conventional pressure-feeding diaphragm pump for a long time. As described above, when the motor 10 is turned on, the wobble plate 40 is rotationally driven by the motor output shaft 11, and the three eccentric circular members 52 of the eccentric circular mounting portion 50 continuously move up and down reciprocatingly. In the meantime, the three pump pistons 80 and the three piston operating zones 74 of the diaphragm membrane 70 are continuously driven by the up and down reciprocating strokes of the three eccentric circular members 52, and are displaced up and down. The force F continuously acts on the three piston action zones 74 with the length of the moment arm L1 from the outer protrusion rim 71 to the periphery of the annular positioning convex portion 76 (see FIG. 13). Therefore, the resultant torque can be derived using the formula “torque = acting force F X length of moment arm L1”, which is obtained by multiplying the acting force F by the length of the moment arm L1. Due to the combined torque, the entire conventional diaphragm pump is directly subjected to vibration. Due to the high speed rotation of the motor output shaft 11 of the motor 10 up to 700-1200 rpm, the vibration intensity caused by the sequential movement of the three eccentric circular members 52 can reach a sustained unacceptable stage.

In order to cope with the direct vibration of the conventional pressure-feeding diaphragm pump, as shown in FIG. 14, a cushion base 100 including a pair of wing plates 101 is always provided as a supplementary support. Each wing plate 101 is further provided with a rubber cushioning member 102 at the sleeve portion in order to enhance the vibration reduction effect. During installation of a conventional pumping diaphragm pump, the cushion base 100 is securely screwed to the housing C of the reverse osmosis purification unit using appropriate fastening screws 103 and corresponding nuts 104. However, when the cushion base 100 is used together with the wing plate 101 and the rubber cushioning member 102, the actual vibration suppression effect corresponds only to the direct primary vibration, and the direct primary vibration is The overall vibration suppression is limited because C causes a secondary vibration that resonates. Due to this resonance, the total vibration noise generated in the housing C of the reverse osmosis purification unit is further increased.

In addition to the disadvantage that the total vibration noise generated in the housing C is increased, the disadvantage is that the water supply pipe P connected to the water outlet orifice 22 of the pump head cover 20 vibrates synchronously with the primary vibration. (See hidden line in FIG. 14). This synchronous vibration of the water supply pipe P may cause a further disadvantage that other parts of the conventional pressure-feeding diaphragm pump are vibrated simultaneously. As a result, after a certain period of time, the connection between the water supply pipe P and the water outlet orifice 22 is gradually loosened, and the coupling between the other parts is also gradually loosened by vibration, so that water leakage from the conventional pressure-feeding diaphragm pump is prevented. Occur.

The overall disadvantages and overall leakage, which are further disadvantages of conventional pumping diaphragm pumps, cannot be solved by the conventional methods of dealing with the aforementioned primary vibrations. A method for substantially reducing the defects due to the vibration of the operation of the pressure-feeding diaphragm pump over the entire surface is an urgent and serious problem.
