1、选择管
1. Selection tube

作为蠕动泵软管的条件具有一定弹性，即软管径向受压后能迅速恢复形状，具有一定的耐磨性，具有一定遭遇压力的能力，不渗漏（气密性好），吸附性低、耐温性好、不易老化、不溶胀、抗侵蚀、析出物高级。
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、选择泵头
2. Select the pump head

选择单、多通道输送流体，是否易于更换软管，是否易于固定软管压管间隙通过棘轮或者其他方式微调，以适应不同壁厚的软管或实现压力的微调滚轮选择：6滚轮结构相对流量稍大；10滚轮结构流体脉动幅度较小扳机结构是否灵巧，开启卡片是否便捷。
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、选择驱动器
3. Select the drive

是否需要进行流量控制，是否需要液量分配，流量范围大小如何，整体结构是否合理、操作是否便捷，流量精度、液量精度是否抵达要求
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.
