Factors affecting the life of peristaltic pump tube
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.
How to choose peristaltic pump tube
The peristaltic pump tube is extruded by platinum vulcanization process, which eliminates the precipitate problem often encountered in other vulcanization methods. So how do we choose the right peristaltic pump tube? First of all, suitable peristaltic pump tube should have the following characteristics: 1. it has a certain elasticity, and the tube can quickly restore shape after radial compression (Shore hardness: 40~80). 2. it has a certain wear resistance. 3. have the ability to withstand pressure. 4. no leakage (good air tightness). 5.low suction, temperature resistance, no aging, no swelling, corrosion resistance, low precipitation.
How much pressure can the peristaltic pump reach
The pressure of the peristaltic pump is determined by the pressure pipe gap and the characteristics of the tube. To understand this problem, we first need to understand how the peristaltic pump produces pressure. Peristaltic pump is to rely on roller extrusion tube to transport liquid, in order to prevent liquid reflux, must always remain sealed, with sealing on the corresponding will produce a certain amount of pressure. The looser the pressure pipe, the lower the pressure, the longer the life of the tube; conversely, the tighter the pressure pipe, the greater the pressure, tighter to a certain extent, with the roller rotation, the tube will cause wear and tear, tube life will be shorter.
