drb365-a mini peristaltic pump aging test

DYX peristaltic pump product models include DRBN20A-01, DRB320A-01, DRB030A-01, DRB130A-01, and DRB365A. These peristaltic pumps are all DC pumps with voltages of DC3.2V, DC5V, DC12V, and DC20V. DYX peristaltic pumps have a wide range of applications, such as sweeping robots, floor scrubbers, soap dispensers, automatic cooking machines, high-end water dispensers, cosmetic dispensers, and medical products. The drb365-a mini peristaltic pump has the largest flow rate, which can reach 0.4-0.5LPM.

Why use a micro dc peristaltic pump?

First of all, the working principle of a dc electric peristaltic pump is to transport liquid through peristaltic motion. When the driver is started, the motor drives the pressure wheel on the pump head to continuously rotate, causing the hose to peristaltic under the action of the pressure wheel, thereby forming a continuous fluid delivery channel. This working principle ensures the stability and accuracy of fluid during transportation, and is especially suitable for scenarios that require high-precision liquid transportation, such as pharmaceutical preparation and chemical reagent mixing.

Secondly, micro-peristaltic pumps have a series of significant advantages. Its compact structure and small size make it easy to install and carry, and is suitable for places where space is limited.

At the same time, the accessories of the mini dc peristaltic pump are also designed with user convenience in mind. For example, the wall thickness of the adaptable hose is 1mm, and the maximum inner diameter can reach 4mm. There is no need for joints to install stuck tubes, making it easy to use. In addition, the housing material of the micro peristaltic pump is corrosion-resistant and can be used in places with poor environments.

Technical Specification

What is the difference between a micro diaphragm pump and a micro peristaltic pump?

From the working principle point of view, the micro diaphragm pump mainly drives the diaphragm inside the pump to do reciprocating motion through the circular motion of the motor or the rotation of the screw, thereby realizing the suction and discharge of gas or liquid. In this process, the diaphragm plays a key role. It directly contacts the liquid or gas being transported, and forms a pressure difference through its own reciprocating motion, thereby completing the pumping work.

In contrast, the working principle of the micro peristaltic pump is more unique. It uses one or more pairs of rollers to squeeze the pump tube to push the fluid in the pipeline forward. This working mode prevents the peristaltic pump from generating shear force on the transported liquid during the transportation process, thereby ensuring the integrity and stability of the liquid. At the same time, since the pump body does not directly contact the transported liquid, the peristaltic pump is also suitable for transporting some corrosive or high-purity liquids.

Secondly, from the structural characteristics, the micro diaphragm pump is usually composed of a drive device, a diaphragm and a pump body, and the structure is relatively simple. The micro peristaltic pump includes components such as a drive device, a roller, and a pump tube. Its pump tube can be selected according to the nature of the transported liquid, and has high flexibility.

Dimension Drawing

What does the suction of a micro 12v peristaltic pump refer to?

When the micro peristaltic dosing pump is working, the motor drives the roller to rotate, and the roller and the pump housing squeeze the pump tube. During the rotation of the roller, the liquid is pushed downstream at the rear end of the pump tube area squeezed by the roller. When the roller leaves, due to the elasticity of the pump tube, the squeezed area will return to a circular tube shape, and a negative pressure will be formed inside the pump tube, which is the so-called "suction".

Function: Start and maintain fluid flow: When the pump starts working, the suction helps start the fluid flow and ensures that the liquid or gas can be smoothly sucked from the inlet. During the continuous operation of the pump, the suction maintains the continuity of this flow.

Overcome pipeline resistance: During the transportation process, there may be various resistances in the pipeline, such as friction resistance, bending resistance, etc. The suction of the micro peristaltic pump can effectively overcome these resistances and ensure that the fluid can pass through the pipeline smoothly.

How does the suction force of a small dc peristaltic pump affect its working efficiency?

First of all, we need to understand that suction is the force generated by the peristaltic pump during operation, which is used to suck liquid or gas from the inlet and push it to the outlet. This force directly determines whether the pump can effectively absorb and transport the medium.

Specifically, when the suction of the dc circulating peristaltic pump is strong enough, it can absorb liquid or gas more quickly and push it to the outlet more smoothly. This not only increases the working speed of the pump, but also ensures the stability and continuity of the delivery process. Therefore, in situations where high efficiency and continuous delivery are required, micro peristaltic pumps with strong suction are undoubtedly more advantageous.

However, if the suction of the micro peristaltic pump is insufficient, it may not be able to effectively absorb liquid or gas, or there may be intermittent situations during the delivery process. This not only reduces the working efficiency of the pump, but may also affect the delivery accuracy and stability. Therefore, when selecting a micro peristaltic pump, it is necessary to evaluate the required suction size based on the specific delivery requirements and medium characteristics.
