Does the micro peristaltic pump pulsate?

Yes, peristaltic mini pumps will produce pulsations when transferring liquids. This is because the peristaltic pump uses rollers to alternately squeeze the hose to transfer liquid. The liquid pumped out each time is between the two rollers.

Liquid capacity, causing the fluid being transferred to flow out in spurts. This pulsation phenomenon may have an impact on the stability and continuity of fluid delivery, especially when precise flow control is required.

occasion. Therefore, in practical applications, it is necessary to select a suitable mini dc peristaltic pump model according to specific needs and occasions, and take measures to reduce the impact of pulsation on fluid delivery.

Why does the micro dc peristaltic pump pulsate?

The pulsation phenomenon of the small dc peristaltic pump is due to its working principle. In a peristaltic pump, the hose is periodically deformed under the squeeze of the roller, thereby generating negative pressure in the tube and sucking the liquid.

into the tube. When the roller rotates through a certain angle, the hose is released and returns to its original shape, pushing the liquid out of the tube. This process is cyclical, so the microperistaltic pump produces the phenomenon of pulsation.

How does the pulsation of a dc electric peristaltic pump affect its working efficiency?

Pulsation will affect the flow stability of the pump, causing periodic fluctuations in the pump's flow output, thus reducing its working efficiency. For processes that require precise control of fluid delivery, pulsation may will produce errors in flow control, thereby affecting the efficiency and stability of the entire process.

Therefore, in practical applications, it is necessary to select a suitable peristaltic pump type according to specific needs and occasions.And take measures to reduce the impact of pulsation on fluid transportation to improve the working efficiency of the peristaltic pump.

How to reduce the impact of pulsation on fluid transportation?

Pulsation is a common problem when peristaltic pumps deliver fluids, which affects the stability and delivery efficiency of the fluid. In order to reduce the impact of pulsation on fluid transportation, the following measures can be taken:

1. Add a buffer container: Adding a buffer container at the outlet of the pump can effectively absorb pulsation and improve the stability of the fluid.

2. Optimize the mini peristaltic pump speed: By adjusting the pump speed, the frequency and amplitude of pulsation can be changed, thereby reducing the impact of pulsation on fluid delivery.

3. Change the starting and stopping method of the pump: Using a gradual starting and stopping method can reduce the acceleration and deceleration of the micro peristaltic pump, thereby reducing the pulsation.

4. Use a pulsation damper: A pulsation damper is a device specially used to reduce pulsation. It can absorb and reduce pulsation and improve the stability of the fluid.

5. Adjust the pipe diameter and layout: By adjusting the pipe diameter and layout, the flow characteristics of the fluid and the transmission mode of pulsation can be changed, thereby reducing the impact of pulsation on fluid transportation.

6. Increase fluid viscosity: Increasing the viscosity of a fluid can reduce the compressibility of the fluid, thereby reducing pulsation. However, this may have an impact on fluid delivery efficiency.

7. Reduce the displacement of the small dc peristaltic pump: Reducing the displacement of the pump can reduce the amount of liquid squeezed each time, thereby reducing pulsation. However, this may affect the pump's delivery efficiency.

8. Use multiple pumps for parallel delivery: By using multiple pumps for parallel delivery, the flow and stability of the fluid can be increased, thereby reducing the impact of pulsation on fluid delivery.

9. Increase the number of stages and rotors of the pump: Increasing the number of stages and rotors of the pump can increase the compression ratio and flow rate of the pump, thereby reducing pulsation. However, this may increase the complexity and cost of the pump.

10. Control the oil replenishment and oil drain methods of the system: Through reasonable oil replenishment and oil drain methods, the inlet and outlet pressure of the pump can be balanced, thereby reducing pulsation.

How to reduce the flow rate of a dc electric peristaltic pump?

The flow rate of a peristaltic water pump can be reduced in the following ways:

1. Adjust the pump speed: The flow rate of the peristaltic pump is directly related to the pump speed. Reducing the pump speed can reduce the pump outlet pressure, thereby reducing the flow rate. Please note that the adjustment speed should be within the rated speed range of the pump to avoid damage to the mechanical parts of the pump.

2. Replace the mini dc peristaltic pump hose with a smaller inner diameter: By replacing the peristaltic pump hose with a smaller inner diameter, the flow rate can be effectively reduced.

3. Use an external switch speed regulator: Connecting an external switch speed regulator can reduce the speed and thus the flow output. But the cost of this method will be relatively high.
