(Summary description)  The peristaltic pump tube is the core component of the peristaltic pump. Its service life determines the service cost of the peristaltic pump. Generally speaking, besides the quality of peristaltic pump tube itself, the compression mode, compression strength, compression times and thermal fatigue aging caused by friction have a great relationship with the service life of peristaltic pump tube.   The main factors that affect the service life of peristaltic pump are as follows:   1. outlet pressure of tube, and outlet pressure such as tube resistance.

Information

  The peristaltic pump tube is the core component of the peristaltic pump. Its service life determines the service cost of the peristaltic pump. Generally speaking, besides the quality of peristaltic pump tube itself, the compression mode, compression strength, compression times and thermal fatigue aging caused by friction have a great relationship with the service life of peristaltic pump tube.

  The main factors that affect the service life of peristaltic pump are as follows:

  1. outlet pressure of tube, and outlet pressure such as tube resistance.

  2. temperature of conveying medium

  High temperature medium will speed up the aging of tube.

  3. speed of pump

  This is one of the decisive factors affecting the peristaltic pump tube, and its speed is basically inversely proportional to the life of the peristaltic pump.

  4. compression tube strength

  Should be moderate, otherwise too small force will lead to medium backflow, inaccurate fluid control, but excessive pressure, will greatly shorten the service life of peristaltic pump tube.

  5. ways of compressing tube

  Tube compression process generally divided into large diameter pressure roller, small diameter roller and slipper 3 kinds. Usually the large diameter press roller is stronger than the small diameter pressure roller, and the small diameter pressure roller is stronger than the slipper.

  6. compatibility between material and conveying medium

  Choose peristaltic pump tube must be matched with the media, different media with different pump tube material, to ensure that there is no reaction between each other, so as not to affect the purity of the media. The materials of the pump tubes include silicon rubber tubes, PVC pump tubes, thermoplastic rubber pump tubes, fluorine rubber tubes and so on.

  7. is there any lubricant?

  The lubricant coating on the outer wall of the pump tube can effectively reduce the friction of the peristaltic pump tube and prolong its service life.

  8. operation state of pump tube

  They are divided into two types: intermittent movement and continuous movement. Because the intermittent motion gives the peristaltic pump tube sufficient rebound setting time, so its service life must be longer than the continuous movement.

  There are many factors affecting the peristaltic pump tube, so even if the same product in different environments, its service life will be very different. In general, the service life of the pump tube manufacturer is to use water as the transmission medium, using specific pump head and rotational speed test data. Customers can reasonably determine the service life of the pump tube according to their own use environment, in order to replace it in time and avoid unnecessary losses.
