蠕动泵选型注意事项

、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.

特殊需求：防护等级 、防爆等级等。外控需求：设备配套、操作方式等，例如RS232、RS458通讯、0－5V外控调速、脉冲调速等
Special requirements: protection grade, explosion-proof grade and so on. External control requirements: Equipment matching, operation mode and so on, such as RS232, RS458 communication, 0 5V external control speed regulation, pulse speed regulation, etc.

蠕动泵优点：
The advantages of the peristaltic pump:

1、无污染：流体只接触泵管，不接触泵体；
1, no pollution: the fluid only contacts the pump tube and does not touch the pump body.

2、精度高：重复精度，稳定性精度高；
2. High precision: repetitive precision, high stability precision;

3、低剪切力：是输送剪切敏感，侵蚀性强流体的梦想工具；
3, low shear force: it is a dream tool for transporting shear sensitive and aggressive fluid.

4、密封性好：具有良好的自吸能力，可空转，可防止回流；
4, good sealing performance: good self suction ability, can be idle, can prevent backflow;

5、掩护简单：无阀门和密封件；
5. The cover is simple: no valves and seals;
