Abstract
The invention discloses a kind of peristaltic pump, it includes the pump housing and pipeline, and the pipeline includes the pump line part being located in the pump housing and the transfusion tube portion outside the pump housing, and the peristaltic pump realizes that accurate quantification is calibrated in the following way：First, default pump speed is v0, peristaltic pump run time is the actual removal amount of liquid p under the conditions of t, actual speed v1=p/t is calculated afterwards, pump speed v0 calibration factor k can be drawn by v0 and v1 ratio again, time t is tuned into by t ' by calibration factor k, when peristaltic pump works again by pump speed v0 rotation time t ', and then accurate liquid relief amount is obtained.Present invention employs prover time method, it is compared at present using calibration pump speed method with higher accuracy.
Description
Technical field
The present invention relates to the accurate quantification calibration method of peristaltic pump, more particularly to a kind of peristaltic pump and peristaltic pump.
Background technology
Rotate extruding pump line toward direction during wriggling pump work, produce the power toward a direction so that solution along this
The direction movement of individual power, realizes the purposes of automatic liquid relief, the velocity of rotation and rotation time of liquid relief amount and peristaltic pump have relation.Pump
Pipe is pressed under peristaltic pump and run after a period of time, due to reasons such as pump line aging, deformation, abrasions, and peristaltic pump rotation can be made to turn around
The amount of liquid drawn changes, this reduces the accuracy of liquid relief amount, and it is all by compacted that the method is solved at present
Dynamic pump is calibrated, and the mode of calibration has the modes such as gravimetric method, volumetric method, no matter which kind of mode used, essential concept is all logical
The purpose for crossing the rotating speed of calibration peristaltic pump to be calibrated, but actually because peristaltic pump is run at various speeds, pump line shape
Change has fine difference, causes the liquid relief amount after calibration to still suffer from difference, it is seen that existing calibration method, its accuracy is poor.
The content of the invention
The technical problem to be solved in the present invention is, in view of the shortcomings of the prior art there is provided a kind of peristaltic pump and its quantitatively
Calibration method, and then realize the accurate quantification calibration to peristaltic pump.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that.
A kind of peristaltic pump, it includes the pump housing and pipeline, and the pipeline includes the pump line part being located in the pump housing and is located at
Transfusion tube portion outside the pump housing, the peristaltic pump realizes that accurate quantification is calibrated in the following way：First, it is υ to preset pump speed
0, peristaltic pump run time is the actual removal amount of liquid p under the conditions of t, actual speed υ 1=p/t is calculated afterwards, then pass through υ 0
Pump speed υ 0 calibration factor k can be drawn with υ 1 ratio, time t is tuned into by t ' by calibration factor k, when peristaltic pump task again
When press the rotation time t ' of pump speed υ 0, and then obtain accurate liquid relief amount.
A kind of accurate quantification calibration method of peristaltic pump, it comprises the following steps：Step S1, it is υ 0 to preset pump speed, is wriggled
The pump operation time is the actual removal amount of liquid p under the conditions of t；Step S2, calculates actual speed υ 1=p/t；Step S3, passes through
υ 0 and υ 1 ratio can draw pump speed υ 0 calibration factor k, and time t is tuned into t ' by calibration factor k；Step S4, peristaltic pump
By the rotation time t ' of pump speed υ 0 when working again, and then obtain accurate liquid relief amount.
Preferably, the amount of liquid p is the accurate volume V or weight m drawn by volumetric method or gravimetric method.
The accurate quantification calibration method of peristaltic pump and peristaltic pump disclosed by the invention, it is drawn after calibration factor k, is not changed
Become pump speed υ 0, but change the run time t of pump, t is tuned into by t ' by calibration factor, i.e., when the pump housing is devoted oneself to work after calibration
Still run by pump speed υ 0, liquid relief amount V ' is obtained after run time t ', because pump speed is constant before and after calibration, i.e. pump line state is in school
It is the same, the simply length of change run time before and after accurate, it is compared to existing technologies, it is to avoid produced because of pump line deformation
Raw fine difference, present invention employs prover time method, it uses calibration pump speed method to have higher accuracy compared to current.

Into t '；
Step S4, by the rotation time t ' of pump speed υ 0 when peristaltic pump works again, and then obtains accurate liquid relief amount.
The accurate quantification calibration method of peristaltic pump and peristaltic pump disclosed by the invention, it is drawn after calibration factor k, is not changed
Become pump speed υ 0, but change the run time t of pump, t is tuned into by t ' by calibration factor, i.e., when the pump housing is devoted oneself to work after calibration
Still run by pump speed υ 0, liquid relief amount V ' is obtained after run time t ', because pump speed is constant before and after calibration, i.e. pump line state is in school
It is the same, the simply length of change run time before and after accurate, it is compared to existing technologies, it is to avoid produced because of pump line deformation
