Abstract

A vibration-reducing structure for a compressing diaphragm pump features a pump head body and a diaphragm membrane. The pump head body comprises three operating holes and a first curved vibration-reducing positioning structure which surrounds an upper surface of each operating hole and is arranged in a circumference. The diaphragm membrane comprises three equivalent piston acting zones and a second curved vibration-reducing position structure placed in a position corresponding to the position of the first curved vibration-reducing positioning structure. The first positioning structure in the pump head body, which may be grooves, slots, perforations, or protrusions, is coupled to the second positioning structure corresponding to the diaphragm membrane which may be protrusions, grooves, slots, or perforations to reduce a moment arm generated during pumping by movement of the diaphragm membrane, thereby generating less torque to decrease strength of vibration and vibration noise.

FIGS. 10 and 11 are views showing a practical operation mode of the conventional compression diaphragm pump of FIGS. 1 to 9. FIG.

First, when power is supplied to the motor 10, the vibration plate 40 is operated by the motor output shaft 11 to rotate, and three eccentric circular plates 52 on the eccentric circular mount 50 are continuously and continuously Moving up and down reciprocal stroke.

Second, the three piston action zones 74 and three pumping pistons 80 in the diaphragm membrane 70 are continuously operated by the up and down reciprocating strokes of the three eccentric circular plates 52, displacement.

Thirdly, when the eccentric circular plate 52 is moved in the downward stroke, the pumping piston 80 and the piston action zone 74 are displaced downward and the piston disk 98 of the piston valve assembly 90 is pushed to the open state, the tap water W flows into the preliminary-pressurizing 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 As indicated by arrows extending from W in an enlarged view of Fig.

Fourth, when the eccentric circular plate 52 is moved in the upward stroke, the pumping piston 80 and the piston action zone 74 are displaced upward so that the piston disk 98 of the piston valve assembly 90 is pulled into the closed state, The tap water W in the pressurizing chamber 26 is compressed to increase the water pressure to a range of 80 psi-100 psi. As a result, the pressurized water Wp pushes the plastic check valve 94 of the piston valve assembly 90 to be opened.

Fifthly, when the plastic check valve 94 of the piston valve assembly 90 is pushed into the open state, the pressurized water Wp in the pre-pressurizing chamber 26 is discharged to the corresponding sector of the central discharge mount 92 Water chamber 27 through the group of ports 95 and then out of the water discharge orifice 22 of the pump head cover 20 (indicated by arrow Wp and shown in Figure 11) ).

Finally, a regular (sequential) repetitive operation for each group of discharge ports 95 for three sectors of the central discharge mount 92 causes the pressurized water Wp to flow out of the conventional compression diaphragm pump continuously To be further RO filtered by the RO cartridge so that the final filtered pressurized water Wp can be used in the reverse osmosis purification system.

Referring to Figs. 12-14, serious disadvantages caused by vibration have existed for a long time in the conventional compression diaphragm pump described above. As described above, when power is supplied to the motor 10, the vibration plate 40 is operated by the motor output shaft 11 to rotate, and the three eccentric circular plates 52 on the eccentric circular mount 50 are continuous While the three piston action zones 74 and the three pumping pistons 80 in the diaphragm membrane 70 are moved up and down the reciprocal stroke of the three eccentric circular plates 52, A moment arm that is continuously operated by a reciprocating stroke and moves up and down to move the equivalent force F from the outer rising rim 71 to the periphery of the annular positioning projection 76, (As shown in Fig. 13) to the three piston operating zones 74 with a length L1 of < RTI ID = 0.0 > a < / RTI > Thereby, the resultant torque is generated by multiplying the acting force F by the length L1 of the moment arm, as indicated by the formula "torque = acting force F x length L1 of the moment arm". The combined torque results in direct vibration in all conventional compression diaphragm pumps. Motor output shaft 11 is 700 in the motor (10) standing jinyeo a high rotation speed to the range of 1200rpm, the vibration, which is caused by replacement (alternately takes place) acts (alternate acting) of the three eccentric circular plate 52 Strength can reach an unacceptable state continuously.

In order to deal with the direct vibration of the conventional compression diaphragm pump, as shown in Fig. 14, a cushion base 100 having a pair of wing plates 101 is always provided as a supplemental support do. Each of the wing plates 101 is further sleeved with a rubber shock absorber 102 for vibration suppression (blocking) improvement. In the installation of the conventional compression diaphragm pump, the cushion base 100 is firmly screwed onto the housing C of the reverse osmosis purification unit by means of a suitable fixing screw 103 and corresponding nut 104. However, the actual vibration suppression efficiency using the cushion base 100 having the wing plate 101 and the rubber shock absorber 102 mentioned above covers only the primary direct vibration, while the basic direct vibration is applied to the housing C The total vibration is reduced only to a limited extent because it causes a second vibration due to the occurrence of resonant shaking. This resonance shake causes the overall vibration noise of the housing C of the reverse osmosis purification unit to become stronger.

In addition to the disadvantage that the overall vibration noise of the housing C increases, a further disadvantage is that it is connected to the water discharge orifice 22 of the pump head cover 20 The water pipe P will cause synchronously shake with resonance with the fundamental oscillation (as indicated by the hypothetical line shown in Fig. 14). This simultaneous shaking of the water pipe P will cause simultaneous shaking of the remaining parts of the conventional compression diaphragm pump, which will cause additional disadvantages. As a result, after a period of time, not only is the fit gradually loosened between the other components affected by the shake, but also the connection between the water pipe P and the water discharge orifice 22 gradually loosens, Water leakage will occur.

A further disadvantage of the overall resonance shake and water leakage in conventional compression diaphragm pumps can not be overcome in the conventional way of addressing the basic vibration disadvantages mentioned above. How to substantially reduce all the disadvantages associated with the operating vibration of a compression diaphragm pump has become an urgent and important issue.

It is an object of the present invention to provide a vibration reduction structure for a compression diaphragm pump characterized by a pump head body and a diaphragm membrane. It is also a further object of the present invention to provide a diaphragm membrane having at least three basic curved grooves, slots or perforated segments, or a pump head body with curved projections, and three basic curved projections, or curved grooves, slots, To provide a vibration-reduction structure for a compression diaphragm pump.

With a small torque, the vibration intensity of the compression diaphragm pump is substantially reduced.

Another object of the present invention is to provide a diaphragm membrane having at least three basic curved grooves, slots or penetrating segments, or a pump head body with curved projections, and three basic curved projections, or curved grooves, slots, or through segments Wherein the three basic curved projections are fully inserted into the corresponding three basic curved grooves, slots, or penetrating segments to form a vibration-reduction structure for a short-length moment arm, Less inductive torque, the torque being achieved by multiplying the length of the moment arm by a constant acting force. With a small torque, the vibration intensity of the compression diaphragm pump is substantially reduced. The present invention, which is supported by a conventional cushion base having a rubber shock absorber and installed on the housing of the reverse osmosis purification unit, can completely remove the cumbersome noise caused by the resonance shake of the conventional compression diaphragm pump.

The vibration-reduction structure for the compression diaphragm pump can substantially reduce the vibration strength of the compression diaphragm pump and is supported by the cushion base and mounted on the housing of the reverse osmosis purification unit, The annoying noise caused by resonance shaking of the diaphragm pump can be completely eliminated.

 Figures 15-22 are views illustrating a first exemplary embodiment of a vibration-reduction structure for a compression diaphragm pump.

A basic curved groove 65 is circumferentially disposed and surrounding a portion of the upper side of each operating hole 61 of the pump head body 60, While a basic curved protrusion 77 surrounds a portion of each concentric annular positioning protrusion 76 on the bottom side of the diaphragm membrane 70 and extends in the circumferential direction The positions of the basic curved grooves 65 and the basic curved projections 77 correspond to each other so that the curved projections 77 extend to the basic curved grooves 65 and mate with the basic curved grooves 65. [

An example of the above-mentioned comparison result shows that the length L2 of the moment arm is shorter than the length L1 of the moment arm.

The resultant torque is calculated (calculated) by multiplying the same acting force F by the length of the moment arm, while the combined torque of the present invention is such that the length L2 of the moment arm is shorter than the length L1 of the moment arm Which is smaller than the combined torque of the conventional compression diaphragm pump.
