DYX Mini Portable DC Electric Peristaltic Pump

How to increase the flow rate of a micro peristaltic pump?

1. Optimize pump head design: For specific fluids and needs, optimize the design of the pump head to improve the fluidity of the fluid and reduce the resistance of the fluid in the pump head, thereby increasing the flow rate.

2. Improve hose material and inner diameter: Select appropriate hose material and inner diameter to adapt to the characteristics and flow requirements of the fluid. For example, using hose materials with high elasticity and low resistance, or appropriately increasing the inner diameter of the hose, can reduce the resistance of the fluid during transmission, thereby increasing the flow rate.

3. Adjust the speed: According to actual needs and conditions, appropriately increase the speed of the mini peristaltic pump. The increase in rotational speed can increase the amount of liquid pumped out per unit time, thereby increasing the flow rate. However, it should be noted that too high a rotational speed may have an impact on the life of the pump, so the rotational speed needs to be considered comprehensively relationship with pump life.

4. Reduce the viscosity of the fluid: Reduce the viscosity of the fluid within the allowable range by heating, dilution, etc. Low-viscosity fluids experience less resistance when flowing in the pump tube, resulting in higher flow rates.

5. Optimize the operating environment of the dc pump: Ensure that the micro peristaltic pump operates in appropriate temperature, humidity, pressure and other environments. Appropriate environmental conditions can reduce the impact of external factors on pump performance, thereby improving flow stability.

What does the pulsation of a micro dc peristaltic pump mean?

The pulsation of the mini dc peristaltic pump refers to the phenomenon that when the peristaltic pump transmits liquid, due to its working principle, the liquid is transmitted in the form of streams. This is because the peristaltic pump uses rollers to alternately squeeze the soft

The pipe is used to transmit liquid, and the liquid pumped out each time is the liquid capacity between the two rollers, which causes the transmitted liquid to flow out one after another, forming a pulsating phenomenon. This pulsation phenomenon may

It has an impact on the stability and continuity of fluid delivery, especially in situations where precise flow control is required. Therefore, in practical applications, it is necessary to select suitable ones according to specific needs and occasions.

Peristaltic pump models, and take measures to reduce the impact of pulsation on fluid delivery.

Technical Specification

What factors affect the flow rate of micro peristaltic pumps?

The flow rate of a small dc peristaltic pump is affected by many factors, including the following aspects:

1. Characteristics of the liquid: The viscosity of the liquid, whether it contains particulate matter and other characteristics have a significant impact on the flow rate of the peristaltic pump. These characteristics of the liquid will affect the suction and lift of the pump, thereby affecting the flow rate.

2. The inner diameter and wall thickness of the hose: The inner diameter and wall thickness of the hose have a direct impact on the flow rate transmitted by the peristaltic pump. Generally speaking, the larger the inner diameter, the greater the flow rate; and the larger the wall thickness, the stronger the pressure to absorb liquid.

3. Pump speed: The higher the pump speed, the higher the flow rate. This is because within a certain period of time, the faster the speed, the greater the amount of liquid pumped out.

4. Pump head design and rotor diameter: The structural design of the pump head and the diameter of the rotor will also affect the flow rate. Generally speaking, the larger the diameter of the rotor, the greater the flow rate.

5. Suction lift and lift: Suction lift refers to how deep the water surface is from the pump and water can be pumped, and lift refers to how high the pumped water can be pumped. These two parameters directly affect traffic flow.

6. Fluid properties: Depending on the liquid being transmitted, the properties of the fluid will also be different. For example, when the flow rate of transmission water is 2000mL/min, if the transmission oil is a liquid with a certain viscosity, the flow rate will inevitably decrease.

7. Environmental factors: Environmental temperature, humidity, air pressure, etc. will also affect the flow rate of the micro peristaltic pump.

What circumstances does a micro peristaltic water pump need self-priming function?

1. Liquid transportation: In many industrial and laboratory applications, liquids need to be transported from one container to another, or from one location to another.

If the liquid storage container is lower than the delivery position, or a certain liquid level difference needs to be overcome, the self-priming function allows the micro peristaltic pump to complete the delivery task without the help of external driving force.

2. Fluid sampling: In fields such as environmental monitoring, chemical analysis, and biological laboratories, fluid sampling is required. The self-priming function of the micro peristaltic pump can make the sampling process more convenient and faster, while ensuring the accuracy and reliability of sampling.

3. Sewage collection: In the field of sewage treatment and wastewater treatment, various fluids need to be collected. The self-priming ability of the  peristaltic dosing pump can help it effectively absorb various sewage or wastewater and transport it to appropriate treatment facilities.

4. Gas transportation: In some applications, gas needs to be transported from one location to another, such as gas sampling or transporting gas samples. The self-priming function of the micro peristaltic pump allows it to complete the gas delivery task without the help of external compression force.

5. Self-priming metering: In some metering applications, a self-priming micro peristaltic pump is required to accurately meter liquids, such as the addition or dilution of chemical reagents. The self-priming function can help the pump quickly reach a stable flow rate when starting, thereby improving metering accuracy and reliability.
