Peristaltic pumps are also called constant flow pumps and hose pumps. The mechanical principle of peristaltic pumps is very simple. It pumps fluid by alternately squeezing and releasing the pump tubing. Just like using two fingers to squeeze a hose filled with liquid, as the finger moves, a negative pressure is created inside the tube, and the liquid flows with it!

     As a professional airliner company engaged in the research and development of peristaltic pumps for many years, Jincheng Peristaltic Pump Co., Ltd. has summarized the following skills in the long-term use, for the majority of peers and users to refer to, please read the ax.

     Tip 1: When the peristaltic pumps are not working, the pressure tube clamp should be loosened to extend the life of the pump tube. Peristaltic pumps rely on compression hoses and hoses to naturally produce suction and fluid transport. To maintain long life of the pump tube, when not using the pump, try to lift the pump head clamp so that the pump tube is naturally unstressed. State to extend pump life.

     Tip 2: When the peristaltic pumps are selected, the pump speed can be reduced to less than 300 rpm under the premise of meeting the flow. The flow of peristaltic pumps is generated by the rotation of the pump head. If the rotation is faster, the pump tube will be used for a shorter period of time, so when it is desired to use the pump tube for a longer period of time, the pump with a larger diameter can be selected as much as possible. Thereby reducing the speed of the pump.

    Tip 3: Use a special tube for peristaltic pumps on the pump head. The other connecting tubes can be used with ordinary pipes. The extruded tubes used on peristaltic pumps require high compressive resilience and tear resistance. Therefore, the material purity of these pump tubes is relatively high and the geometrical accuracy is high, which results in higher peristaltic pumps. Therefore, it is more economical to use a common pipe as the connecting pipe.

    Tip 4: The entrance of the peristaltic pumps should be as short as possible. The joints and caliber of the pipes should not be lower than the caliber of the tubes installed in the pump head. The peristaltic pump suction is generated by the rebound of the pump tube. If the pipeline, especially the inlet pipeline, is too long or the diameter is small, the suction resistance will be too large. If the resistance is too large, the pump will be blocked, so the actual delivery. Traffic can be greatly lost. Similarly, if the outlet pipe becomes smaller or the pipe is too long, the discharge pressure of the peristaltic pumps is usually small, and when the discharge resistance is too large, the output flow rate is lowered.

    Tip 5: The theoretical flow rate is greater than the actual flow rate when selecting the peristaltic pumps, preferably greater than 30%. The peristaltic pumps are soft, so the negative pressure and discharge pressure generated by them are small. If the liquid to be delivered has a certain viscosity or the pipeline has a certain length, the actual flow loss will be caused. In order to achieve the required flow rate selection. The theoretical flow is slightly higher than the actual flow.

    Tip 6: Peristaltic pumps should pay attention to cleaning the debris on the pump casing and pump tube during use. Since the peristaltic pumps are relatively precise instruments, the pump casing is mainly used to maintain a high precision gap, so that the pump tube can be squeezed efficiently. If the inflowing liquid adheres to the pump casing pressure roller and the pressure block and the pump tube due to the damage of the pump tube, Will change the pressure gap of the pump head, even a slight change will cause excessive premature wear of the pump tube, which will seriously affect the pump head damage caused by the pump head.

     Tip 7: Peristaltic pumps should be regularly checked for wear on the pump tube when in use. Because the peristaltic pumps are wearing parts, once they are damaged, liquid leakage will occur. Therefore, it is necessary to check the surface of the pump casing for early grinding to prevent the pump tube from being damaged.

    Tip 8: When selecting the peristaltic pumps, pay attention to whether the liquid to be delivered will corrode the pump tube. Because the pump tube is made of many materials, there are many kinds of liquids to be transported. There is no pump tube that can withstand all liquids. Therefore, you need to confirm your own liquid type, compare it with a chemical compatibility meter or ensure the pump tube by immersion test.
