Description

Damping device for diaphragm pump

Technical Field

The utility model belongs to the technical field of the shock attenuation equipment, especially, relate to a damping device for diaphragm pump.

Background

Diaphragm pumps, also known as control pumps, are a more specific form of positive displacement pumps. It relies on the back and forth movement of a diaphragm to vary the volume of the working chamber to draw and expel fluid. The diaphragm pump is the main type of actuator by receiving a control signal output by a modulation unit. Diaphragm pumps operate by power to vary the fluid flow by varying the working chamber volume to intake and exhaust fluid by virtue of a back and forth diaphragm. Because the diaphragm pump can produce the vibration at the course of the work, can produce great noise after this vibration passes through base transmission to the complete machine. The existing diaphragm pump base is not provided with a buffering and damping structure, and only a damping rubber pad is arranged at the fixed connection part of a bolt of the whole diaphragm pump base, but the damping effect is poor.

Therefore, how to solve the above problems becomes a focus of research by those skilled in the art.
