How to improve the service life of peristaltic pump hose

After choosing a suitable Peristaltic Pump Tube, understanding the use skills of the Peristaltic Pump can make the life of the peristaltic pump silicone tube longer

To

1. The peristaltic pump relies on the natural rebound of the compressed hose and hose to generate suction and fluid delivery. When the peristaltic pump is not working, loosen the pressure tube block to make the pump tube in a natural uncompressed state, which can extend the life of the pump tube.

2. Under the premise of satisfying the flow rate, the peristaltic pump should reduce the pump speed to less than 300 revolutions as much as possible. The faster the speed of the pump head, the shorter the time the pump tube can be used, so choose a pump with a larger tube diameter as much as possible to reduce the pump speed and prolong the service life of the hose.

3. Use a special pipe for the peristaltic pump on the pump head, and use ordinary pipes for the other connecting pipes. Because the extruded tube used in the peristaltic pump needs good compression, resilience, and tear resistance, the material purity of these pump tubes is relatively high, the wall thickness and shape accuracy are relatively high, and the price is relatively high. Therefore, it is more economical to use ordinary pipes as connecting pipes.

4. The inlet of the peristaltic pump pipe should be as short as possible, and the joint and diameter of the pipe should not be lower than the pipe diameter of the pump head. If the inlet pipe of the peristaltic pump is too long or the caliber becomes smaller, it will cause excessive resistance at the suction end. If the resistance is too large, the rebound of the pump tube will be blocked, so the actual flow delivered will be greatly lost. In the same way, if the diameter of the outlet pipeline becomes smaller or the pipeline is too long, the discharge pressure of the peristaltic pump is usually small. When the discharge resistance is too large, the output flow will decrease.

5. When selecting a peristaltic pump, the theoretical flow rate should be greater than the actual flow rate, preferably greater than 30%. The peristaltic pump tube is relatively soft, so the negative pressure and discharge pressure generated by it is small. If the conveyed liquid has a certain viscosity or the pipeline has a certain length, it will cause

The actual flow loss, to achieve the required flow selection, the theoretical flow must be slightly higher than the actual flow.

6. During the use of the peristaltic pump, pay attention to cleaning up the debris on the pump casing and pump tube. Because the peristaltic pump mainly relies on the pump casing to maintain a high-precision gap, the pump tube is efficiently squeezed. If the liquid adheres to the pump casing roller and pressure block and the pump tube, the compression gap of the pump head will be changed, resulting in the pump Excessive premature wear of the pipe will seriously affect the pump head and cause damage to the pump head.

7. When the peristaltic pump is in use, check the abrasion of the pump tube regularly. Because the peristaltic pump tube is a vulnerable part, once it is damaged, it will cause liquid leakage. Therefore, it is necessary to check the surface of the pump meter in time to prevent the pump tube from being damaged.

8. When choosing a peristaltic pump, pay attention to whether the liquid that needs to be transported will corrode the pump tube. It is necessary to compare the chemical compatibility table or make sure that the pump tube can be used through the immersion experiment.
