The service life is a topic that people are more concerned about, after all, we all hope that the longer the service life of the peristaltic pump, the better, but often the actual value is lower than the theoretical value, which is why? I believe that reading the following article, you will understand.

1, when the pump is not working, loosening the pressure block can extend the life of the pump tube. Peristaltic pump is through the pump head roller repeatedly extrusion hose and hose natural rebound to produce suction to achieve fluid delivery, want to maintain the longevity of the pump tube, when not using the pump, try to lift the pump head press block, so that the pump tube in a natural state of non-pressure, thereby extending the life of the pump tube.

2, selection in the premise of meeting customer flow requirements, as far as possible to reduce the pump speed to less than 300 RPM. The flow of peristaltic pump is generated by the rotation of the pump head roller, the faster the rotation, the shorter the service life of the pump tube, when you want to use the pump tube longer, you can choose a relatively large diameter, thereby reducing the speed of the pump.

3, pump head with peristaltic pump special pipe, the rest of the connection pipe ordinary pipe. The extruded tube used on the peristaltic pump needs good compressive resilience and tear resistance, so the material purity of these pump tubes is relatively high, the wall thickness and shape accuracy are high, which will cause the price of peristaltic pump tubes to be higher. Therefore, special tubes are used on the peristaltic pump to ensure the service life, and ordinary pipes are connected to make the whole system more economical and applicable.

4, the pump pipe inlet as short as possible, the joint and caliber of the pipeline should not be lower than the caliber of the stuck pipe installed in the pump head. Peristaltic pump suction is generated by the pump pipe rebound, if the pipeline, especially the inlet pipe passing long or diameter becomes small, it will cause the suction end resistance is too large, the resistance is too large pump pipe rebound will be blocked, so the actual flow of the transport will be greatly lost. In the same way, if the diameter of the outlet pipeline is smaller or the pipe is long, because the discharge pressure of the peristaltic pump is usually small, when the discharge resistance is too large, the output flow will be reduced.

5, the theoretical flow rate of peristaltic pump selection is greater than the actual flow rate of more than 30%. The peristaltic pump tube is soft, so the negative pressure and discharge pressure generated by it are small, if the liquid delivered has a certain viscosity or the pipeline has a certain length, it will cause the loss of the actual flow, in order to achieve the required flow, the theoretical flow should be slightly higher than the actual flow.

6, the pump should pay attention to clean up the debris on the pump shell and pump pipe during use. Because the peristaltic pump is a relatively precise instrument, mainly rely on the pump shell to maintain a high precision gap, so as to efficiently squeeze the pump tube, if the pump tube is damaged and the flow of liquid sticks to the pump shell pressure wheel and block and pump tube, it will change the pressure gap of the pump head, even small changes will cause excessive premature wear of the pump tube, which will seriously affect the damage of the pump head.

7, when the peristaltic pump is used, it is necessary to check the wear of the pump pipe regularly. Because the peristaltic pump tube is a wearing part, once damaged, it will cause liquid leakage, so it is necessary to check the surface of the pump tube in time whether there is an early grinding to prevent the pump tube from being damaged.

8, when choosing the peristaltic pump, pay attention to whether the liquid that needs to be transported will corrode the pump pipe. Because the pump tube has more materials and the types of liquids transported are also very many, no pump tube can withstand all the liquids, so you need to confirm your own liquid type, compare it through the chemical compatibility table or make sure that the pump tube can be used through the immersion experiment. If you do not understand it, you can see the relevant article "Choose the Peristaltic pump hose tutorial".

9, the operating temperature range is also an important factor to consider. Different materials have different temperature performance, some pipes such as silicone rubber have a wide temperature range, suitable for high temperature and low temperature processes; Some pipes are only suitable for a small temperature range. Before selecting the pipe, the user should first find out the high and low temperature in the system to ensure that the selected pump pipe works safely in this temperature range and improves its service life. There are so many reasons to reduce the service life of the pump, I believe that after reading this article you can have a systematic understanding of the pump.
