The service life is a topic of more concern, 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, why is this? Read the following article and you will understand.

1, when the pump does not work, loosen the pressure pipe block can extend the life of the pump pipe. Peristaltic pump is through the pump head roller repeatedly extrusion hose and hose natural rebound suction to achieve fluid delivery, want to maintain the longevity of the pump tube, when not using the pump, as far as possible to lift the pump head press block, so that the pump tube in a natural state of non-compression, so as to extend 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 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 will be. When the pump tube is expected to be used for a longer time, the relatively large diameter can be selected to reduce the speed of the pump.

3, pump head with peristaltic pump special pipe, the rest of the connection pipe ordinary pipe. The peristaltic pump with the extrusion tube because of the need for good compressive resilience, tear resistance, so the pump tube material purity is relatively high, wall thickness and shape accuracy is higher, which will cause the price of peristaltic pump tube is higher. Therefore, the peristaltic pump adopts special pipe to ensure the service life, and connects the ordinary pipe, so that the whole system is more economical and applicable.

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

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

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

7, when the peristaltic pump is used, the wear of the pump pipe should be checked regularly. Because the peristaltic pump tube is wearing parts, once damaged will cause liquid leakage, so we should timely check whether the surface of the pump tube has early grinding, in order to prevent the damage of the pump tube.

8, in the choice of peristaltic pump to pay attention to the need to transport the liquid will not corrosion pump pipe. Because there are many materials of the pump tube and many types of liquid to be transported, no pump tube can withstand all the liquids, so we need to confirm our own type of liquid, and make comparison through the chemical compatibility table or immersion experiment to ensure that the pump tube can be used. For those who are not familiar with it, please refer to the relevant article "How to choose the peristaltic pump hose".

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 process; Some pipes are suitable only for a smaller temperature range. Before selecting the pipe, users should make clear the high and low temperature in the system to ensure that the selected pump pipe works safely within this temperature range and improve its service life. There are so many reasons to reduce the service life of the pump, I believe you can read this article to have a systematic understanding of the pump.
