Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of diaphragm pumps, in particular to a low-noise shock absorption and vibration isolation type diaphragm pump. BACKGROUND

[0002] A diaphragm pump is a pump that uses the reciprocating motion of a diaphragm to pump liquid. Its working principle is to form a pressure difference through the up and down movement of the diaphragm, so that the liquid enters the pump and is discharged. A diaphragm pump is usually composed of a pump body, a diaphragm, a valve and a driving mechanism, etc. During the operation of the pump, when the diaphragm moves downward, negative pressure is generated in the pump, and liquid enters the pump body through the inlet valve. When the diaphragm moves upward, the pressure in the pump increases, and the liquid is discharged through the outlet valve. Due to its structural characteristics, the diaphragm pump can handle fluids containing solid particles and corrosive liquids, and is widely used in chemical, pharmaceutical, food, environmental protection and other fields.

The damping device is arranged on the lower surface of the support foot. The damping device includes a load plate, the upper surface of the load plate is fixedly connected to the support foot, and the lower surface of the load plate is fixedly connected with a plurality of horizontally equidistantly arranged buffer springs.
