The peristaltic pump silicone tube must be tested in all aspects before use, otherwise it will damage the service life of the silicone tube. The following is a simple introduction of the Puri fluid. We should test from the following aspects:

1, before detecting the size of the peristaltic pump silicone tube, we first have to look at its appearance, pay attention to observe whether there are bubbles, impurities, black spots, etc., once there are these, it will affect its service life, followed by the detection size, size precision, will directly affect the flow of the pump, the flow is mainly determined by the inner diameter of the hose, the larger the diameter, the greater the flow. The outer diameter or wall thickness affects the life of the hose. If the wall thickness exceeds the conventional tolerance, the hose will appear hard, which affects the operation of the pump body.

2. Test the wear resistance, fatigue resistance and resilience of the silicone tube of peristaltic pump. It is recommended to adopt the limit test method, adjust the peristaltic pump speed to the highest speed, transport weakly corrosive fluid.

3. Test the aging resistance and corrosion resistance of the silicone tube of peristaltic pump. Take a sample tube, record its weight, inner and outer diameter, length and other parameters, soak the hose in a glass beaker, take out the hose 72 hours later, clean it with clean water, dry it, measure its weight, inner and outer diameter and length again, and observe its changes; Check whether the hose is soft, brittle, white, crack and so on. If there is any change, it means that the hose has been affected by the chemical of the liquid, indicating that the pump pipe aging resistance, corrosion resistance is poor. The sample of each candidate pump tube shall be put into the actual plant environment for test run, and the test results shall be closely observed. If there is no fading, swelling, cracking, loss of fluidity, or other signs of deterioration of the pump tube after trial operation, it is proved that the pump tube has excellent chemical stability.

4, finally, is the phase certification of peristaltic pump silicone tube, such as FDA, LFGB, USP CLASS VI, etc., which need to be determined according to the actual application field of peristaltic pump.

Above is the peristaltic pump silicone tube need to do several aspects of the test before use, want to know more about the knowledge of silicone tube, you can consult the relevant technical personnel of Purui fluid.
