    There are many types of industrial pumps, such as constant flow pumps, metering pumps, etc. Peristaltic pumps are one of the subdivided products with medium and small flow rates. The main working principle is to pump the liquid through the roller squeezing the hose. Here I will share with you some basic knowledge of peristaltic pumps, hoping to help you.
Tips for using Peristaltic Pumps
 
    1. Try to avoid too long suction lift
 
    Try to keep the distance between the inlet and outlet hoses as short as possible. The peristaltic pump mainly generates suction by the rebound of the pump tube. If the pipeline is too long, the pressure at the inlet will increase, and the actual flow rate will become inaccurate. , and if the outlet end is too long, the discharge pressure of the pump will be too high, and the output flow will decrease.

    2. Pay attention to cleaning
 
    When using a peristaltic pump, pay attention to keeping the pump body clean. If the working environment is harsh, it is recommended to directly cover the pump body with a plastic film, which will not affect the observation and use, but also provides good protection.
 
    3. How to adjust the error
 
    When the peristaltic pump is just used, the transmission flow may be different due to the different transmission medium and the length of the hose, so it can be adjusted through flow calibration, combined with the manual or our operation video. A technician can be consulted.
 
    4. Can errors be avoided?
 
    After the adjustment, many people hope that there will be no error at all. This peristaltic pump cannot do it. The displayed flow value is calculated based on the slope of the transmission curve caused by different specifications of hoses. Usually there is a linear relationship, so calibration Finally, when the speed changes, errors will occur. If you need extremely low errors, it is recommended to use high-precision pumps such as syringe pumps.
 
    5. Installation attention
 
    The peristaltic pump is generally assembled except for the hose when it leaves the factory. Although the installation of the hose is simple, it should be noted that the hose is in the center of the roller during installation, and the hoses on both sides are stuck in the center, otherwise the hose will be damaged.
