When the distributed peristaltic pump is used for timing and quantitative feeding, relative constant flow feeding and precise titration of liquid medicine, the flow calibration should be carried out first. If the flow still has deviation after one calibration, or the flow has deviation after the calibration has been put into use for a period of time, the same method can be used to calibrate again, so as to improve the measurement accuracy.
Flow calibration operation method:
(1) Enter the "flow correction" page and confirm that the pipeline has been fully filled (there is no air in the pipe). If it has not been fully filled, please start the peristaltic pump to perform filling. (in the flow correction mode, it will stop automatically after running for a period of time after starting) (2) prepare a container, clear the weight of the container on the electronic scale, place the container at the outlet of the pump pipe, press the start / stop key to start the peristaltic pump, and measure the amount of materials pumped (the unit can be ml, G, kg, etc.) after the peristaltic pump stops automatically. It is better to measure several times with the same method and take the average value of several times.
(3) Press the ENT key, cooperate with the up and down keys, and input the value measured in the previous step as the calibration value. For example, if the value measured in the previous step is 84.0g, set the "calibration value" to "84.00"; Then press ESC to exit the flow correction page.
(4) After calibration, if the flow or speed is reset, and the new value changes more than the original value, it shall be recalibrated.
Precautions for calibration operation:
(1) The rotating speed at calibration time is generally not less than 20rpm.
(2) After replacing the new pump pipe, run it at full speed for several minutes before calibration, and the effect is better.
(3) It is better to calibrate when the liquid level of raw material barrel is in the middle position (half barrel).
The distributive peristaltic pump plays the role of other pumps in the fields of high clean material transportation, precise flow control, precise dosing and micro filling. Correct use and reasonable maintenance are the necessary conditions to give full play to the superior performance of peristaltic pump.
1、 At the initial stage of using the peristaltic pump, pay attention to the service life of the pump pipe and make records. After use, try to replace the pump pipe before it reaches the expected service life.
II. In case of pipe breakage and leakage, the pump head shall be cleaned in time to prevent corrosive materials and easily solidified materials from damaging the roller parts of the pump head.
3、 Frequently check the operation flexibility of the roller, and timely repair the roller if it is found to be inflexible.
4、 The power supply must have a reliable grounding wire, which is the most important safety rule.
5、 Cut off the power supply when replacing the pump pipe and cleaning the machine body.
6、 Do not use a dripping cloth to wipe the signal terminals on the operation panel and the back of the chassis.
