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.

The four bases for the selection of peristaltic pumps peristaltic pumps use rotating rollers to squeeze the hose to transport fluid. As the fluid only flows in the hose, it does not contact the pump body, and will not cause cross pollution. At the same time, the conveying accuracy is high and the shear effect is small. As peristaltic pump driver is a high-precision equipment integrating machinery, electronics and software, which can receive a variety of external control signals to achieve external signal control, it is often used as an ideal equipment for industrial supporting and distributed control. Then I'll give you a brief introduction of the 4 basis for the selection of peristaltic pump.

1. Determination of requirements

Since the model is selected, you should first determine your own needs, mainly including: flow size, accuracy requirements, transmission medium, channel number, pressure range, suction range and control mode.

2. Selection of pump head

Number of channels: determine the number of channels according to the workload demand.

Number of rollers: the number of rollers is the key factor to determine the pulsation, and the number of rollers depends on the pulsation requirements.

Disassembly method: simple and convenient disassembly method is a good choice.

3. Selection of hose

Inner diameter: the inner diameter is proportional to the flow.

Wall thickness: the greater the pressure, the greater the wall thickness is required.

Material: special medium, special function hose shall be selected, such as corrosion resistance, acid resistance, strong acid resistance, organic resistance

4. Driver selection

Speed: the speed is proportional to the flow. Refer to the parameter diagram.

Accuracy: select the corresponding rotary actuator for different accuracy.

Protection grade: different environments have different requirements for product protection grade. For example, if the working environment requires waterproof and dustproof, the driver corresponding to the IP grade shall be selected.

Flow
How much flow can be pumped?
The BT series peristaltic pump can provide a flow range of 0.035 to 2280 ml/min.

How accurate is the flow rate?
After adopting the calibrated flow pump system, the flow error range can be less than +/-0.5%. Using other pump systems, the flow error range can be less than +/-3%, which meets the requirements of general pumping applications.

Are the volume measurements repeatable?
With the calibrated pump system, the repeat error of the volume measurement can be less than or equal to +/-0.25%.

What effect does viscosity have on fluidity?
The fluidity of all fluids is based on the fluidity of water. The greater the viscosity of the fluid, the lower the flow rate.

Pump head
What is the upper pressure limit?
Depends on the pump tube used. Under normal circumstances, the upper pressure limit of the pump tube is 40 psig (2.7 bar); the nominal pressure is 25 psig (1.7 bar). The company’s PTFE pump head has an upper pressure limit of 100 pounds per square foot during operation.

What is the upper limit of inlet pressure?
It depends on the inner diameter, wall thickness and material of the pump tube used. Normally, the upper pressure limit at the inlet is 40 psi (2.7 bar). The company’s PTFE pump head has an upper pressure limit of 100 pounds per square foot during operation.

Can the peristaltic pump run idly?
Can. It can pump gas, liquid and multiphase mixed fluid. However, the company's PTFE pump head will overheat when idling, so it cannot pump gas.

Is the peristaltic pump a self-priming pump?
Yes. It can generate a vacuum of more than 26 inches of mercury (660 mm of mercury).

Is the peristaltic pump a positive displacement pump?
Yes. The flow of water is proportional to the speed of the rotor.

Is the peristaltic pump non-siphonic?
Yes. At any moment, there is always a roller pressed through the pump tube to lock it, so there will be no backflow.

Can you pump slurry fluids or abrasive solutions?
Can. However, the upper limit of the pumpable viscosity and particle size is related to the inner diameter of the pump tube used.

Is it easy to replace the pump tube?
Not difficult. Easy-install pump head, easy-install II pump head, high-performance pump head, cassette pump head, and quick-install pump tube can be replaced quickly and easily. For the standard pump head, the pump tube can be easily replaced as long as the supplied pump key is used.
