Description
Technical Parameters
Peristaltic pump dispenser is one of the core components of peristaltic pump, it is usually called peristaltic pump driver or compression device, its main function is to periodically squeeze and release the elastic hose through the roller, press block or other forms of compression elements. This extrusion and release process makes the fluid in the hose flow forward under the action of pressure, so as to achieve the delivery of fluid. By precisely controlling the rotation speed, direction and extrusion force of the roller or the press block, the distributor can realize the precise adjustment and control of the fluid delivery volume.
The peristaltic pump distributor is usually composed of a motor, a reducer, a transmission mechanism and a roller (or a press block). The motor provides power to drive the speed reducer to rotate, and the speed reducer converts the rotating motion of the motor into the extrusion motion of the roller (or press block) through the transmission mechanism. When the roller (or presser) squeezes the hose, the fluid in the hose is compressed and moves forward; When the roller (or press block) releases the squeeze on the hose, the hose returns to its original state, and the fluid continues to flow forward under the negative pressure in the hose. Fluid is continuously pumped out by continuous extrusion and release.

Flow calibration-Important steps to ensure accurate flow output
Calibration step
Go to the traffic correction page
First, you need to go to the "Flow correction" page of the peristaltic pump distributor.
Check that the pipe is completely filled (there is no air in the pipe). If the pipe is not filled, start the peristaltic pump to fill the pipe. In flow correction mode, it automatically stops after running for a period of time after starting.
Prepare the measuring vessel
Prepare a container and zero the container weight on an electronic scale.
Place the container at the pump line outlet ready to receive the fluid flowing from the device.
Start peristaltic pump and record flow rate
Press the start and stop button to start the peristaltic pump, after the peristaltic pump automatically stops, measure and record the amount of the pumped material (the unit can be milliliters, grams, kilograms, etc.).
In order to improve the accuracy of the measurement, it is recommended to measure several times and take an average value.
Enter the calibration value
Press Ent key, and cooperate with up and down keys, input the value measured in the previous step as the calibration value.
For example, if the previous step measured a value of 84.0 grams, set the "calibration value" to "84.00".
Then press Esc to exit the traffic correction page.
Precautions
Calibration conditions
When calibrated, the speed is generally not less than 20rpm.
After replacing the new pump tube, it is recommended to run at full speed for a few minutes before calibration, in order to obtain more accurate calibration results.
When the liquid level of the raw material barrel is in the middle position (half the barrel), the calibration effect is better.
01
Re-calibrate
If the flow rate or speed is reset after calibration, and the new value changes significantly from the original value, the calibration should be re-performed.
If the flow is still deviated after a calibration, or the flow deviation occurs after the calibration is put into use for a period of time, it can also be calibrated again using the same method to improve the measurement accuracy.
02
Operation specification
When calibrating the flow, ensure that all connections are tight and leak-free to avoid fluid leakage affecting the measurement results.
During the measurement process, a stable measurement environment should be maintained to avoid interference from external factors to the measurement results.
03
Safety precautions
When performing maintenance or calibration of the peristaltic pump distributor, ensure that the power supply is cut off to avoid electric shock or equipment damage.
When handling corrosive, toxic, or flammable fluids, take appropriate safety measures, such as wearing protective gloves and glasses.
04
Details to be noted
The following aspects should be paid attention to in flow calibration：
Pre-calibration preparation
Confirm pipe status: Before flow calibration, ensure that the pipe is completely filled, that is, there is no air in the pipe. If the pipe is not completely filled, the peristaltic pump should be started to fill until the pipe is filled with fluid.
Prepare measuring tools: Prepare an accurate measuring container and electronic scale for measuring the amount of fluid flowing out of the peristaltic pump dispenser. Ensure that the capacity of the measuring vessel is large enough to accommodate the fluid that flows out during the calibration process.
Calibration process
Set calibration parameters: Enter the flow calibration page of peristaltic pump distributor, and set calibration parameters according to actual needs, such as speed, running time, etc. In general, the calibration speed is generally not less than 20rpm.
Start calibration: Place the measuring vessel at the outlet of the pump tube and press the start stop button to start the peristaltic pump. After the peristaltic pump automatically stops, immediately measure and record the amount of pumped material. In order to improve the accuracy of the measurement, it is recommended to measure several times and take an average value.
Input calibration value: Input the measured average value as calibration value into the flow correction page of the peristaltic pump distributor. Ensure that the entered values are correct to avoid errors in subsequent use.
Post-calibration processing
Check the calibration results: After the calibration is completed, the calibration results should be checked to see if they meet expectations. If there is a large deviation between the calibration result and the actual demand, the calibration should be re-calibrated until the requirements are met.
Record calibration data: the data and results obtained in the calibration process are recorded for subsequent analysis and reference. This helps to understand the performance changes of the peristaltic pump distributor and provides a basis for subsequent maintenance.

Use suitable lubricating oil and operate according to the instructions to avoid excess or insufficient.
Pump pipe and seal replacement
Regularly check pump pipes and seals (such as hose, O-rings, etc.) for wear or aging.
If the pump pipe is found to be cracked, deformed or blocked, it should be replaced in time to avoid affecting the pumping effect and flow accuracy.
If the seal is damaged, it should also be replaced in time to ensure the tightness of the pump body and prevent liquid leakage.
