Service life is a topic of concern for people, after all, everyone hopes that the longer the service life of peristaltic pumps, the better, but often the actual value is lower than the theoretical value. Why is this? I believe you will understand by reading the following article.

1. Releasing the pressure block of the pressure pipe when the pump is not working can extend the service life of the pump pipe. The peristaltic pump achieves fluid delivery by repeatedly squeezing the hose and the natural rebound of the hose through the pump head roller. To maintain the longevity of the pump pipe, try to lift the pump head pressure block when not using the pump, so that the pump pipe is in a naturally non pressurized state, thereby extending the service life of the pump pipe.

2. When selecting, while meeting the customer's flow requirements, try to reduce the pump speed to within 300 revolutions as much as possible. The flow rate of a peristaltic pump is generated by the rotation of the pump head roller. The faster the rotation, the shorter the service life of the pump pipe. When you want the pump pipe to last longer, you can choose a relatively larger pipe diameter to reduce the pump speed.

3. Special pipes for peristaltic pumps are used on the pump head, and ordinary pipes are used for other connecting pipes. The extrusion pipes used on peristaltic pumps require good compressive resilience and tear resistance, so the material purity, wall thickness, and shape accuracy of these pump pipes are relatively high, which leads to higher prices for peristaltic pump pipes. Therefore, dedicated pipes are used on the peristaltic pump to ensure its service life, and ordinary pipelines are used to connect the pipes, making the entire system more economical and applicable.

4. The inlet of the pump pipe should be as short as possible, and the joint and diameter of the pipeline should not be lower than the diameter of the clamp pipe installed on the pump head. The suction force of a peristaltic pump is generated by the rebound of the pump pipe. If the pipeline, especially the inlet pipeline, is too long or the diameter becomes small, it will cause excessive resistance at the suction end. If the resistance is too large, the rebound of the pump pipe will be hindered, and thus the actual flow rate transported will be greatly lost. Similarly, if the diameter of the outlet pipeline becomes smaller or the pipeline is too long, the discharge pressure of the peristaltic pump is usually smaller. When the discharge resistance is too large, it will cause a decrease in output flow.

5. When selecting a peristaltic pump, the theoretical flow rate should be greater than the actual flow rate by more than 30%. The peristaltic pump pipe is relatively soft, so the negative pressure and discharge pressure generated by it are relatively small. If the conveyed liquid has a certain viscosity or the pipeline has a certain length, it will cause a loss of actual flow rate. In order to achieve the required flow rate, the theoretical flow rate should be slightly higher than the actual flow rate when selecting.

6. During the use of the pump, attention should be paid to cleaning the debris on the pump casing and pump pipe. Due to the fact that peristaltic pumps are relatively precise instruments, they mainly rely on the pump casing to maintain a high-precision gap, thereby efficiently squeezing the pump pipe. If the liquid flows into the pump casing pressure wheel, pressure block, and pump pipe due to damage to the pump pipe, it will change the compression gap of the pump head. Even small changes can cause excessive and premature wear of the pump pipe, which can seriously affect the pump head and cause damage to the pump head.

7. When using peristaltic pumps, it is necessary to regularly check the wear of the pump pipes. Because the peristaltic pump pipe is a vulnerable component, once damaged, it can cause liquid leakage. Therefore, it is necessary to promptly check the surface of the pump pipe for early wear to prevent damage to the pump pipe.

8. When choosing a peristaltic pump, it is important to pay attention to whether the liquid to be conveyed will corrode the pump pipe. Due to the variety of materials used in pump pipes and the variety of liquids conveyed, no pump pipe can withstand all liquids. Therefore, it is necessary to confirm the type of liquid you have, compare it through a chemical compatibility table, or ensure that the pump pipe can be used through immersion experiments
