Vibration-reducing structure for compressing diaphragm pump

Abstract

A vibration-reducing method for reducing vibrations and vibration noise in a compressing diaphragm pump includes the step of disposing a vibration-reducing unit between the pump head body and a diaphragm membrane to reduce a length of the moment arm, and therefore of the torque, generated upon up and down movement of the diaphragm membrane during pumping.

AI Technical Summary

Benefits of technology

The patent text describes a method for reducing vibration and noise in a compressing diaphragm pump. The method includes a vibration-reducing unit that is placed between the pump head body and the diaphragm membrane. This unit reduces torque by shortening the length of the moment arm, which decreases the strength of vibration and vibration noise. The vibration-reducing unit can be designed with basic curved indents and protrusions that fit into corresponding curved indentations on the pump head body and diaphragm membrane. The technical benefit of this invention is to offer a more efficient and effective approach for reducing vibration and noise in compressing diaphragm pumps.

Problems solved by technology

Referring to FIGS. 12 through 14, a primary serious drawback has long existed in the foregoing conventional compressing diaphragm pump.

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

This synchronous shaking” of the water pipe P will further cause other parts of the conventional compressing diaphragm pump to also simultaneously shake.

Consequently, the overall resonant shaking aforesaid will cause vibration of the housing C of the reverse osmosis purification unit to become stronger, increasing vibration noise and, after a certain period, causing water leakage of the conventional compressing diaphragm pump due to a gradually loosened connection between water pipe P and water outlet orifice 22, as well as gradual loosening of other parts affected by the shaking.

However, the practical vibration suppressing efficiency of using foregoing cushion base 100 with wing plates 101 and rubber shock absorber 102 only affects the primary vibrating drawback to a limited degree, and does not solve the drawbacks of overall resonant shaking or water leakage for the conventional compressing diaphragm pump.

The problem of substantially reducing all of the drawbacks associated with the operating vibration of the compressing diaphragm pump has become an urgent and critical issue.
