How to improve the service life of peristaltic pump hoses in pharmaceutical indu

In the pharmaceutical field, peristaltic pumps have high accuracy in application, low flow rate, can transmit highly viscous liquids, and non-polluting and non-corrosive pump pipe types are extremely popular.
In the pharmaceutical field, peristaltic pumps have high accuracy in application, low flow rate, can transmit highly viscous liquids, and non-polluting and non-corrosive pump pipe types are extremely popular. Experts said that when the customer chooses a peristaltic pump, whether it is an industrial peristaltic pump, a laboratory peristaltic pump, or a liquid medicine transmission peristaltic pump, the transmission accuracy of the peristaltic pump determines the work efficiency, and the transmission accuracy of the peristaltic pump requires a good peristaltic pump body, peristaltic pump pump head and hose. Among them, the peristaltic pump hose is the main working part of peristaltic pump, and its performance directly affects the accuracy and stability of peristaltic pump flow. There are many factors that affect the life of the peristaltic pump hose, such as the running speed of the pump head, the material of the hose and the gap between the pump head roller and the arc.

Fatigue damage is the main manifestation of hose rupture, and the running speed of the pump head needs to be adjusted. When choosing a peristaltic pump, you should try to choose a pump head with a larger flow rate, which can also run at a lower speed, thereby extending the life of the hose. The choice of material plays an important role in the overall performance of the peristaltic pump hose. Domestic hoses are generally food-grade silicone tubes with a generally calibrated life of 200 hours (uninterrupted operation at 600rpm), while under the same conditions, imported hoses can have a long life of more than 1200 hours. In contrast, the price of imported hoses will be much more than that of domestic. However, the industry said that the imported hose also needs to be selected according to the actual use, and not all the imported hose life is very long, some materials of the imported pipe life may be much shorter than the domestic hose, only suitable for use in some special occasions.

In addition, the size of the pressure pipe gap and the uniformity of the pressure pipe gap also affect the life of the peristaltic pump hose. Such as whether the curve of the arc is uniform, the size of the processing error of the roller and the wheel, and the assembly error of the center of the roller and the center of the arc. If the pressure pipe gap is not uniform, in order to ensure the air tightness of the pump head, the position of the minimum pressure will not leak, so that the rest of the place will be overpressure (the gap is smaller than the normal value), which will reduce the local life of the hose.
