Tip 1

When the peristaltic pump is selected, it can reduce the pump speed to within 300 rpm as much as possible while satisfying the flow rate. The peristaltic pump flow is generated by the rotation of the pump head. If the rotation is faster, the pump tube will be used for a shorter time. Therefore, when it is desired to use the pump tube for a longer period of time, a larger diameter pump can be selected as much as possible. This reduces the speed of the pump.

Tip 2

When the peristaltic pump is not working, the pressure tube clamp should be released to extend the life of the pump tube. Peristaltic pumps rely on the natural rebound of compression hoses and hoses to generate suction and fluid delivery. To maintain the longevity of the pump tubes, when the pump is not in use, try to lift the pump head pressure piece so that the pump tube is naturally unpressurized. State, thereby extending pump tubing life.

Tip 3

The peristaltic pump is used for the pump head, and the remaining connecting pipe can be used as an ordinary pipe. The squeeze tube used on the peristaltic pump needs good pressure resilience and tear resistance, so the material purity of these pump tubes is relatively high and the geometrical dimension precision is high, which will result in higher peristaltic pump tube prices. Therefore, it is more economical to use common pipes for connecting pipes.

Tip 4

The inlet of the peristaltic pump tube should be as short as possible. The fitting and diameter of the tube should not be lower than the diameter of the tube 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 of the pipeline is too small, it will cause the resistance of the suction end to be too large. If the resistance is too large, the rebound of the pump tubing will be hindered, so the actual delivery will be impeded. Traffic will be greatly lost. Similarly, if the outlet pipe is smaller in diameter or the pipe is too long, the discharge pressure of the peristaltic pump is usually small. When the discharge resistance is too large, the output flow rate will decrease.

Tip 5

Peristaltic pump selection when the theoretical flow is greater than the actual flow, it is best to be greater than 30%. The peristaltic pump tube is soft, so the negative pressure and discharge pressure generated by the peristaltic pump tube are small. If the delivered liquid has a certain viscosity or the tube has a certain length, it will cause a loss of the actual flow, in order to achieve the required flow selection. The theoretical flow should be slightly higher than the actual flow.

Tip 6

When selecting a peristaltic pump, be aware that the liquid that needs to be transported will not corrode the pump tube. Because the material of the pump tube is large and there are many kinds of liquids to be transported, there is no pump tube that can tolerate all liquids. Therefore, you need to confirm your own liquid type, and make sure to compare the chemical compatibility chart or ensure that the pump tube is tested by immersion. can use. When selecting a peristaltic pump, be aware that the liquid that needs to be transported will not corrode the pump tube.

Tip 7

When the peristaltic pump is in use, check the wear of the pump tubing regularly. Because the peristaltic pump tube is a consumable part, once it is damaged, it will cause liquid leakage. Therefore, it is necessary to promptly check the surface of the pump casing for early grinding to prevent the pump tube from being damaged.

Tip 8

Peristaltic pump should pay attention to clean up the impurities on the pump casing and pump tube during use. As the peristaltic pump is a more sophisticated instrument, it mainly depends on the pump casing to maintain a high precision clearance, so that the pump tubing can be squeezed efficiently. If the pump tubing is damaged, the inflow liquid will stick to the pump shell pressure wheel and the pressure block and pump tubing. It will change the compression gap of the pump head. Minor changes will also cause excessive premature wear of the pump tubing, which will seriously affect the pump head's damage to the pump head.
