Abstract

The utility model provides a low-flow buffer shock damper provided with a buffer cavity inside, and a water inlet and an outlet at both ends, and capable of stabilizing the flow rate of liquid flowing through the low-flow buffer shock damper. The utility model has the advantages of simple structure, convenient manufacture and low cost, and can be used for technologies of dialysis, perfusion, analysis for liquid chromatography, etc., and in places needing to provide stable flow rate and no low frequency shock.

Description

Low discharge buffering vibration absorber
The utility model relates to low discharge buffering weakening technical field.
In research and production, usually need flow speed stability, do not have the liquid of low-frequency vibration to export.And peristaltic pump commonly used or other continuous liquid output unit be because self characteristics, and the liquid of output has pulse character, and other machinery of upstream produces various low-frequency vibrations simultaneously, also down propagates along flowing liquid.
The purpose of this utility model is to provide a kind of flow rate of liquid that can make stable, does not have the low discharge buffering vibration absorber of low-frequency vibration.
The utility model is realized in the following ways.
Inside of the present utility model is the buffering cavity, and two ends are entery and delivery port.Buffering can be provided with tubule in the cavity, and tubule is connected with water intake on the wall.Have relief opening on the wall on water intake side.
The utility model shakes with the buffer compartment of gas and act as the basis, utilize the compressibility of gas itself to come crest, the trough of fluctuation pulse are adjusted on the one hand, reach the effect that subtracts ripple, utilize the reflected refraction of shock wave on gas one liquid interface that vibrational energy is decayed on the other hand and spread, thereby reach suppressor pulse, isolate and eliminate the purpose of low-frequency vibration, finally form one constant working fluid.The utility model is simple in structure, and is easy to make, and cost is low.The utility model can be used in the technology such as dialysis, perfusion, liquid-phase chromatographic analysis, and the place that flow speed stability, no low-frequency vibration liquid need be provided.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing 1, the utility model structural representation.Wherein, 1-water intake, 2-relief opening, 3-tubule, 4-buffer cavity, 5-water outlet.
Referring to accompanying drawing, enter from the water intake 1 of buffer upper end by connecting flexible pipe from the working fluid of the needs buffering weakening of pump output, flow into buffer cavitys 4 by the glass tubule 3 that is positioned at the buffer inside center.Have air in certain amount in the buffer cavity 4, the elasticity that this air in certain amount had can make the liquid in the buffer cavity 4 obtain cushioning weakening.At last, discharge from the water outlet 5 of buffer lower end, become the fluid that a branch of calmness flows through the liquid of buffering weakening.This line body can utilize the connection flexible pipe to pick in the instrument and equipment in downstream.
The amesiality mouth of pipe in buffer upper end is the relief opening 2 that is provided with for controller buffer gas inside amount.In real work, open relief opening 2 earlier, allow liquid freely inject a period of time in the buffer.By the time after certain amount of fluid has been accumulated in buffer inside, again relief opening is shut.Through after a while, the liquid of buffer output steadily and has not fluctuateed with regard to becoming so again.
Whole buffer useable glass or other material are made.If: the total discharge of each pulse is V ', and buffer internal cavities volume is V, environment constant latm ≈ 10.3m water column, buffer input output pressure difference is represented with loss of head: 10 centimeter water columns.
The relative change rate of flow velocity: &Delta;V / V < 10.3 m &times; V &prime; V &times; 10 cm Just can determine the volume V of needed buffer cavity according to the value of V ' in the real work and to the requirement of △ V/V like this.
