What does peristaltic pump hose need to do?

The peristaltic pump hose improves the service life of the hose on the peristaltic pump; * Elasticity and resilience, good compression characteristics; Smooth tube walls provide balanced solution flow, inhibit bacterial growth, and tolerate continuous peristaltic pump pumping.

How do we test the peristaltic pump hose?

1 detection of peristaltic pump hose size before, first to look at its appearance, pay attention to observe whether there are bubbles, impurities, black spots, etc., once there are these, will affect its service life, followed by the detection size, size precision, 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 will eventually affect the life of the hose. If the wall thickness exceeds the conventional tolerance, the hose will appear hard, which will eventually affect the operation of the pump body.

2. Test the wear resistance, fatigue resistance and resilience of the peristaltic pump hose. It is recommended to adopt the limit test method, adjust the peristaltic pump speed to z high speed, transport weakly corrosive fluid, and pay attention to the change of the flow of the peristaltic pump every day.

3. Test aging resistance and corrosion resistance of peristaltic pump hose. 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. Then is the phase certification required for peristaltic pump hose, such as FDA, LFGB, USP CLASS VI, etc., which need to be determined according to the actual application field of peristaltic pump.
