■低维护-无密封件,无阀门
- low maintenance - no seals, no valve
■很好的自吸功能-非虹吸,可干转并自吸整套系统
- good self-priming function non - siphon, dry and self suction system
绝大多数蠕动泵系统都包括三个组件:泵头、泵管,以及驱动器,下面我们就来谈谈,组件的选购要点;
Most of the peristaltic pump system comprises three components: pump head, pump, and drive, we are going to talk about, buy points of components;
1.选择管
1. selection tube
◆作为蠕动泵软管的条件
As the peristaltic pump hose condition
·具有一定弹性,即软管径向受压后能迅速恢复形状
• a certain flexibility, that is, the hose can be quickly restored to shape after radial compression
·具有一定的耐磨性
It has a certain wear resistance
·具有一定承受压力的能力
• ability to cope with pressure
·不渗漏(气密性好)
No leakage (good air tightness)
·吸附性低、耐温性好、不易老化、不溶胀、抗腐蚀、析出物低等
Low adsorption, good temperature resistance, aging, swelling, corrosion resistance and low precipitation
◆选择软管应考虑如下因素
The choice of hose should consider the following factors
·抗化学腐蚀性/化学相容性
Chemical resistance / chemical compatibility
传输不同的流体时,软管应表现出一定优良化学性能,即称之为化学相容。如:吸附性低、耐温性好、不易老化、不溶胀、抗腐蚀、析出物低等
When transporting different fluids, the hose shall exhibit certain good chemical properties, which is called chemical compatibility. Such as: low adsorption, good temperature resistance, not aging, swelling, corrosion resistance, low precipitation
抗化学腐蚀性能随温度的升高而降低,在室温下对管没影响的化学药品可能随温度升高对软管产生影响。
The resistance to chemical corrosion decreases with increasing temperature, and chemicals that do not affect the tube at room temperature may have an effect on the hose as the temperature increases.
·承压
Pressure bearing
蠕动泵的应用受软管承压性能的限制。
The application of peristaltic pump is limited by the pressure bearing performance of the hose.
如果系统压力达到超过软管的极限承压,软管会膨胀,导致软管的过度磨损或软管破裂。
If the system pressure exceeds the limit of the hose, the hose will expand and cause excessive wear of the hose or hose rupture.
影响软管承压的因素有:材料、直径与壁厚的比例等。
The factors affecting the pressure of the hose include material, diameter and wall thickness.
·温度
Temperature
软管适应工作温度范围是用户要考虑的因素。不同材料有不同的温度表现。
Flexible hose operating temperature range is a factor for users to consider. Different materials have different temperature performance.
·尺寸
Size
软管的尺寸对流量有直接影响,优秀泵设计会考虑适用软管的内径和壁厚,匹配最佳软管尺寸或管号范围。软管的内径决定了流量;壁厚影响软管被压缩回弹的能力,对软管的寿命也有很大影响。
The size of the hose has a direct bearing on the flow. Excellent pump design will take into account the inner diameter and wall thickness of the hose and match the best hose size or pipe number range. The inner diameter of the hose determines the flow rate; the wall thickness affects the hose's ability to compress and rebound; it also has a great effect on the life of the hose.
·认证
Certified
软管用于相关用途时可能要通过相关的认证。如美国药典标准USP, 欧洲药典标准EP,美国食品药物管理标准FDA, 美国农业部标准USDA和国家卫生基金会标准NSF。
Hoses used for related purposes may be subject to relevant certification. Such as USP standard USP, European Pharmacopoeia Standard EP, American food and drug administration standard FDA, USDA standard USDA and national health foundation standard NSF.
·软管的柔性/弹性/寿命
Flexible / flexible / life of hose
不同软管耐滚轮反复挤压、摩擦的能力不同。不同的管型、管材、泵头、运行速度有不同的寿命。使用寿命在泵系统中叫柔性寿命,在特定的应用中,泵的特性是很一致的。选择长寿命、厚壁管,选用大流量泵,运行在较低转速时可以获得更长的软管使用寿命。
Different hose, roller resistance, repeated extrusion, friction ability is different. Different pipe types, tubing, pump head and running speed have different life. The service life is called the flexible life in the pump system, and the pump characteristic is very consistent in the specific application. Choose long life, thick wall pipe, choose large flow pump, run at a lower speed, you can get longer hose life.
2.泵头选择要点
2. pump head selection points
选择单、多通道输送流体
Single and multichannel fluid delivery is selected
是否易于更换软管
Is it easy to replace the hose?
是否易于固定软管
Is it easy to secure the hose?
压管间隙通过棘轮微调,以适应不同壁厚的软管
The tubing gap is adjusted by ratcheting to fit hose with different wall thicknesses
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
Roller selection: 6 roller structure relative flow is slightly larger; 10 roller structure fluid pulsation amplitude is smaller
扳机结构是否灵巧,开启卡片是否便捷
The trigger structure is smart and it is convenient to open the card
3.驱动器选择要点
3. drive selection points
是否需要进行流量控制
Is flow control necessary?
是否需要流量可以分配
Do you need traffic to be assigned?
流量大小如何
What is the size of the flow?
防护等级
Protection level
整体构造是否合理
Is the overall structure reasonable?
