As a peristaltic pump tube, it needs to be somewhat elastic, meaning it can quickly recover its shape after being radially compressed. It needs to be wear-resistant, able to withstand pressure, leak-proof (good airtightness), have low adsorption
1. Select tube
1. Selection tube
As a peristaltic pump tube, it must meet certain conditions: It should possess elasticity, quickly recovering its shape after radial compression; It must also have wear resistance, pressure tolerance, and good air tightness (no leakage); and finally, it should exhibit low adsorption, good temperature resistance, aging resistance, non-swelling, corrosion resistance and minimal precipitate.
As a peristaltic pump, the condition of the hose has a certain elasticity, that is, the hose can quickly restore shape after the radial compression. It has a certain wear resistance, a certain ability to encounter pressure, no leakage (good air tightness), low adsorption, good temperature resistance, not easy to aging, swelling, corrosion resistance, precipitate advanced.
2. Select pump head
2. Select the pump head
Consider whether single or multi-channel fluid transport is needed, ease of hose replacement and fixation, and the ability to fine-tune the hose compression gap via ratchet or other mechanism to accommodate different hose thicknesses or achieve pressure fine-tuning. Roller selection: A 6-roller structure offers a slightly higher flow rate; a 10-roller structure reduces fluid pulsation. Evaluate the trigger mechanism's dexterity and ease of opening.
Choose single, multi-channel fluid, easy to replace hose, easy to fix hose clearance through ratchet or other way, to adapt to different wall thickness hose or pressure trimming roller selection: 6 roller structure relatively large relative flow; 10 roller structure fluid pulsating smaller trigger structure or not Dexterity, it is convenient to open the card.
3. Select the driver
3. Select the drive
Consider the need for flow control and liquid dispensing, the flow range, the rationality of the overall structure, ease of operation, and whether the flow accuracy and liquid volume accuracy meet requirements.
Is it necessary to control the flow of flow, whether it is necessary for the distribution of liquid, the size of the flow range, the rationality of the overall structure, the convenience of the operation, the arrival of the flow accuracy and the accuracy of the liquid volume.
