How does the peristaltic pump achieve very good efficiency?

1. When the peristaltic pump is not working, loosening the pressure block can prolong the life of the pump tube. The peristaltic pump relies on the natural rebound of compressed hoses and hoses to generate suction and fluid delivery. To maintain the longevity of the pump tube, when the pump is not in use, try to lift the pump head pressure block so that the pump tube is naturally uncompressed State, thereby extending the life of the pump tube.

 

2. When selecting the peristaltic pump, under the premise of satisfying the flow, the pump speed can be reduced to less than 300 revolutions. The flow of the peristaltic pump is generated by the rotation of the pump head. If the rotation is faster, the pump tube will be used for a shorter time. Therefore, when you want the pump tube to be used for a longer time, you can choose a pump with a larger tube diameter as much as possible. Thereby reducing the speed of the pump.

 

3. The pump head uses special pipes for peristaltic pumps, and the other connecting pipes use ordinary pipes. Extrusion tubes used on peristaltic pumps require good compression, resilience, and tear resistance. Therefore, the material purity of these pump tubes is relatively high, and the wall thickness and shape accuracy are high, which will result in higher prices for peristaltic pump tubes. 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. Peristaltic pump suction is produced by the rebound of the pump tube. If the pipeline, especially the inlet pipeline, is too long or the diameter 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 delivery Traffic will suffer a big loss. 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, generally greater than 30%. The peristaltic pump tube is soft, so the negative pressure and discharge pressure generated by it are small. If the conveyed liquid 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 rate selection The theoretical flow rate is slightly higher than the actual flow rate.

 

6. When using the peristaltic pump, pay attention to cleaning up the debris on the pump casing and pump tube. Because the peristaltic pump is a relative instrument, it mainly relies on the pump casing to maintain a high-precision gap, so as to squeeze the pump tube with high efficiency. It will change the compression gap of the pump head, even a small change will cause excessive premature wear of the pump tube, which will seriously affect the pump head and cause damage to the pump head.

 

7. When using the peristaltic pump, check the wear 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 to be transported will corrode the pump tube. Because the pump tube is made of many materials, and the type of liquid to be transported is also very large, no pump tube can withstand all liquids, so you need to confirm your own liquid type, compare the chemical compatibility table or ensure the pump tube through immersion experiment can use.
