1.化学相容性在为泵送腐化性流体抉择蠕动泵时,要害是抉择准确的泵管资料。选错泵管会招致险情,有可能损坏装备及危及人身保险。请查问泵及泵控制作商所供给的每项用处的化学相容性表。应用新的或未表明级别的化学物资前须对泵停止试验。将一小段泵管浸入流体中。检讨泵管尺寸、色彩、分量及强度的变更情形。可能的话,在拉伸应用泵管前,测试一下泵中的泵管。泵管受挤压时期发生绕曲,会将化学物资揉入管壁中,减速管材的老化崩溃。
2.无传染性在试验室研讨、制药、生物技巧产物出产等很多应用处所中,将流体断绝至关重要。已有大批研讨论证了硅胶管及硅基资料不会与种种生物资料发生化学反映。另有别的品种的一些资料也存在此种机能,而且可到达USP Class VI 级请求。有些泵则采取了用惰性PTFE管材制成的泵管组件。
3.抗绕曲才能差别管材蒙受辊子重复碾压的才能也各别。个别而言,特定的泵管尺寸、泵管资料、泵头范例、以及运行速率这多少项参数的组合决议了泵管的应用寿命。泵管应用寿命,或在泵中的挠曲屈从极限是投入新应用前的重要斟酌要素。现在,在体系中应用热塑性分解橡胶(TPE),泵管运行寿命超越500小时已是很平常的事件。在某一特定应用处所中,泵的机能是十分稳固的。筛选抗绕曲能较大的管材、采取较厚的管壁或筛选较大的泵及应用较低的运行速率等均可最大限制地延伸泵管的应用任务。
4.清楚度对某些应用处所,为清楚懂得灌泵或干运行等任务进程,能透过管道察看流体的活动情形是十分有代价的。但从另一方面讲,欠亨明管材则对一些光敏流体有利益。
5.管壁硬度对断定某一特定管道的泵送才能至关重要。泵管太软,则易破坏;泵管太硬,则泵不能任务。可用硬度计(如Shore A等)来测定特定管材的物感机能。
6.流体压力平日对泵管运送压力流体的才能构成制约。大少数蠕动泵采取无支持管道。这类泵管的压力极限为2至3Pa(30至45磅/平房英寸)。市场上一些较大型的泵则采取带支持管道(带编织物强化层)。浸泡在光滑液中的泵管可蒙受高达15至20Pa(300磅/平房英寸)的压力。

1. Chemical compatibility When choosing a creep pump for the pump, the key is to select accurate pump tube data. Choosing the wrong pump tube will incur risks and may damage equipment and endanger personal insurance. Please check the chemical compatibility table for each use supplied by the pump and pump control manufacturer. Test the pump before applying new or unspecified grade chemicals. Immerse a small pump tube into the fluid. Review changes in pump tube size, color, component and strength. If possible, test the pump tube in the pump before stretching the pump tube. When the pump tube is squeezed, a winding occurs, and the chemical material is rubbed into the wall of the pipe to slow down the aging of the pipe material.
2. Non-infectious in many applications such as laboratory research, pharmaceuticals, and production of biotech products, it is crucial to cut off fluids. A large number of researches have been conducted to prove that the Guanji data will not react chemically with various biological data. Some other types of data also exist and can reach USP Class VI requests. Some pumps use pump tube assemblies made of inert PTFE pipes.
3. The ability to resist winding can be different from the ability of the tube to suffer repeated rolling of the roller. Individually, the application life of the pump pipe is determined by the combination of specific pump pipe size, pump pipe data, pump head example, and operation rate. The service life of the pump pipe or the bending yield limit in the pump is an important discretionary factor before entering new applications. It is now common to use thermoplastic decomposition rubber(TPE) in a system with a pump tube operating life exceeding 500 hours. In a particular application, the function of the pump is very stable. The application task of the pump tube can be extended to the maximum limit by selecting the pipe with larger winding resistance, adopting thicker pipe walls or screening larger pumps and applying lower operating rates.
4. For certain applications, it is very costly to see the fluid movement through the pipeline in order to clearly understand the task process such as pumping or dry operation. However, on the other hand, it is of interest to some photosensitive fluids that the Hengming tube is not available.
5. Pipe wall hardness is crucial to determine the pumping ability of a particular pipe. The pump tube is too soft, it is easy to destroy; If the pump tube is too hard, the pump can not be task. Hardenometers(such as Shore A, etc.) can be used to determine the sensory function of specific tubes.
6. Fluid pressure normally restricts the ability of the pump tube to transport pressure fluids. Most creep pumps take unsupported pipes. The pressure limit for this type of pump tube is 2 to 3 Pa(30 to 45 lbs. / cottage inch). Some of the larger pumps on the market take the belt support pipe(with woven reinforced layer). A pump tube soaked in smooth liquid can withstand pressure up to 15 to 20 Pa(300 lbs. / cottage in.).
