[ Hongjie Water ] Working principle and function of metering pump damper

Metering pump is a device used to deliver precise flow, which is widely used in industrial fields and laboratories. The damper is one of the important components, which plays a key role in the working process of the pump. Below I will introduce the function and principle of the damper in detail.

The damper plays an important role in the metering pump, which can control and stabilize the flow of the liquid. It has the following functions: smooth output flow, by slowing down the working speed of the pump, the fluid is pumped out in a more stable way to ensure the stability of the flow output; reduce pulsation, effectively reduce or eliminate the periodic changes in the output flow, and improve the accuracy and stability of the flow; adjust the flow range, change the parameters of the damper or select different dampers as needed to achieve the operation of the pump in different flow ranges. These functions make the damper have a wide range of application value in the metering pump system and improve the performance and adaptability of the pump.

The damper principle is based on the interaction between fluid dynamics and mechanical motion. Common metering pump dampers usually adopt piston or diaphragm structure.

The piston damper consists of a piston, a damping liquid and a regulating device. The liquid is controlled by the movement of the piston and the damping device to achieve flow regulation and stabilization. During operation, the liquid flows from the pump inlet into the piston chamber, and the piston then starts to move. The control device of the damper controls the movement speed and position of the piston by adjusting the flow and pressure of the damping liquid, thereby achieving flow regulation and stable output.
The diaphragm damper is a device consisting of two chambers, which are separated from each other by a flexible diaphragm. Its principle is to achieve the fluid delivery and damping effect by the liquid entering from one chamber to another. During operation, the inflow and outflow of the liquid causes the diaphragm to vibrate and deform, thereby achieving the pumping of the liquid and the regulation of the flow. This vibration can be controlled by springs or gas pressure to stabilize the output flow. At the same time, the resistance generated during the vibration of the diaphragm can be adjusted by the damping liquid. The viscosity and resistance characteristics of the damping liquid affect the speed and amplitude of the diaphragm vibration, thereby achieving the effect of smooth flow regulation and pulsation reduction. Commonly used damping liquids include liquids with higher viscosity such as liquid silicone or special damping oil.

In general, the damper in the metering pump achieves a stable output of flow and reduces pulsation by controlling the movement speed of the piston or diaphragm and the resistance of the damping liquid. The design and adjustment parameters of the damper can be optimized according to specific application requirements to meet the metering pump operation with different flow ranges and accuracy requirements.
