Vibration-reducing structure for five-compressing-chamber diaphragm pump

Abstract

A vibration-reducing structure for five-compressing-chamber diaphragm pump features a pump head body and a diaphragm membrane. The pump head body includes five operating holes and a basic curved dent circum-disposed around the upper side of each operating hole. The diaphragm membrane includes five equivalent piston acting zones such that each of which has a acting zone hole with an annular positioning protrusion for each acting zone hole and a basic curved protrusion circum-disposed around each concentric annular positioning protrusion in corresponding position with each mating basic curved dent in the pump head body. Thereby, five basic curved protrusions completely insert into corresponding five basic curved dents with a short length of moment arm in generating less torque, which is obtained by length of moment arm multiplying a constant acting force and primarily causes adverse vibration. With less torque, the vibration strength of the five-compressing-chamber diaphragm pump is substantially reduced.

Description

[0001]This application claims the benefit of provisional U.S. Patent Application No. 62 / 000,653, filed May 20, 2014, and incorporated herein by reference.FIELD OF THE PRESENT INVENTION[0002]The present invention relates to a vibration-reducing structure for five-compressing-chamber diaphragm pump, particularly for one structure that can reduce the “vibration strength” of the pump so that the annoying noise incurred by the “consonant vibration” with the housing of reverse osmosis purification (RO) purification system is deleted when it is installed on the commercial water supplying apparatus of large scale in either the settled home, recreational vehicle or mobile homeBACKGROUND OF THE INVENTION[0003]Currently, the conventional five-compressing-chamber diaphragm pumps exclusively used with RO (Reverse Osmosis) purifier or RO water purification system, which is popularly installed on the water supplying apparatus in either the settled home, recreational vehicle or mobile home, have so...

AI Technical Summary

Benefits of technology

The invention is a vibration-reducing structure for a diaphragm pump that includes a pump head body and a diaphragm membrane. The pump head body has five operating holes and curved dent around each hole and the diaphragm membrane has five equivalent piston acting zones with matching curved dent. This reduces torque and vibration, making the pump run smoother. This structure can be used in a reverse osmosis purification unit and can also eliminate noise caused by the pump's vibrations.

Problems solved by technology

Referring to FIGS. 12 through 14, a primary serious drawback has long-lasting existed in the foregoing conventional five-compressing-chamber diaphragm pump as below.

However, the resultant torque causes the whole conventional five-compressing-chamber diaphragm pump to vibrate directly.

However, the practical vibration suppressing efficiency of using foregoing cushion base 100 with wing plates 101 and rubber shock absorber 102 only affects to the primary vibrating drawback aforesaid and in limited degree because the overall “resonant shakes” aforesaid will incur the vibration of the housing C for the reverse osmosis purification unit to become stronger with harassing noise.

Therefore, how to substantially reduce all the drawbacks associated with the operating vibration for the five-compressing-chamber diaphragm pump becomes an urgent and critical issue.

Therefore, how to substantially reduce all the drawbacks associated with the operating vibration for the five-compressing-chamber diaphragm pump becomes an urgent and critical issue indeed.
