Service life is a topic that people are concerned about. After all, we all hope that the service life of peristaltic pump as long as possible, but the actual value is often lower than the theoretical value. Why is that?

1. When the pump does not work, loosen the pressure pipe block to prolong the life of the pump pipe. The peristaltic pump achieves fluid transfer by repeatedly squeezing the hose with the roller of the pump head and the hose naturally bouncing back. In order to maintain the life of the pump tube, when the pump is not in use, try to lift the pressure block of the pump head, so that the pump tube is in a natural pressure free state, so as to extend the service life of the pump tube.

2, selection, in the premise of meeting customer flow requirements, try to reduce the speed of the pump to less than 300 revolutions. The flow of peristaltic pump is generated by the rotation of the pump head roller. The faster the rotation, the shorter the service life of the pump tube. When you want the pump tube to last longer, you can choose a relatively large diameter to reduce the pump. The speed of rotation.

3, pump head use peristaltic pump special pipe, other connecting pipe use ordinary pipe. The squeezable tube used by peristaltic pump requires good compression resilience and tear resistance, so the material purity of these pump tubes is relatively high, the wall thickness and shape accuracy are required to be high, which will lead to the price of peristaltic pump tubes. Therefore, the peristaltic pump on the use of special pipeline to ensure the service life, and the use of ordinary pipeline to connect the pipeline, so that the whole system is more economical and applicable.

4. The inlet of the pump pipe should be as short as possible, and the joint and diameter of the pipeline should not be lower than the diameter of the pipe installed in the pump head. The suction of peristaltic pump is produced by the rebound of pump pipe. If the pipeline, especially the inlet pipe passing long or pipe diameter becomes smaller, the suction end resistance will be too large, too large resistance will hinder the rebound of the pump pipe. As a result, the actual traffic will be greatly lost. Similarly, if the outlet pipe diameter becomes smaller or the pipe passes long, because the discharge pressure of the peristaltic pump is usually smaller, when the discharge resistance is too large, the output flow will be reduced.

5, the selection of peristaltic pump, the theoretical flow should be greater than 30% of the actual flow. The peristaltic pump tube is softer, so it produces less negative pressure and less discharge pressure. If the liquid being transported has a certain viscosity or the pipe has a certain length, the actual flow loss will be caused. In order to achieve the required traffic, the traffic at the selected time is slightly higher than the actual traffic.

6, pump in the process of use, pay attention to clean up the debris on the pump shell and pump pipe. Because the peristaltic pump is a relatively precise instrument, it mainly relies on the pump shell to maintain a high precision clearance, so as to efficiently squeeze the pump tube. It can change the compression clearance of the pump head, and even a small change can cause excessive and premature wear of the pump tube, which can seriously affect the pump head and cause damage to the pump head.

7, the peristaltic pump in the process of use, to regularly check the wear of the pump pipe. Because the peristaltic pump pipe is wearing parts, once damaged, it will cause leakage. Therefore, it is necessary to check whether there is early wear on the surface of the pump pipe in time to prevent damage to the pump pipe.

8, choose peristaltic pump should pay attention to whether the liquid will be transported corrosion pump pipe. Because the pump tube material is a lot, need to transport a lot of liquid types, no pump tube can withstand all the liquid, so we need to confirm the type of their own liquid, with the chemical compatibility comparison table or ensure that the pump tube through the immersion test is safe, can be used.

9. The operating temperature range is also an important factor to consider. Different materials have different temperature properties. Some pipes, such as silicone rubber, have a wide temperature range and are suitable for high and low temperature processes; And some pipes are only suitable for smaller temperature ranges. Before choosing the pump pipe, the user should first understand the high and low temperature in the system to ensure that the selected pump pipe works safely in this temperature range and extends its service life.
