As a small but powerful fluid transport equipment, micro-peristaltic pump has many advantages, such as no pollution, high precision, low shear force, strong corrosion resistance, good sealing and simple maintenance, but there are also some disadvantages. The following is a detailed supplement to the shortcomings of the micro-peristaltic pump:
Pressure limitation: Microperistaltic pumps use flexible tubes as pumping elements, which limits the range of pressures they can withstand. In high pressure environments, the pump tube may be damaged by excessive extrusion, which affects the pumping effect and service life.
Pulse flow: During operation, the micro-peristaltic pump will generate pulse flow. This is because the pump tube is periodically squeezed and released, resulting in the flow of fluid in the pump tube is pulsed. This type of pulse flow may not be suitable in some application scenarios where a steady continuous flow rate is required.
Flow attenuation: With the increase of use time, the elasticity of pump pipe materials (such as rubber, silicone, etc.) will gradually deteriorate, resulting in a decrease in pumping efficiency and flow attenuation. This affects the accuracy and stability of the pumped fluid.
Aging of the pump tube: The pump tube is a wearing part in the micro-peristaltic pump, and aging will occur after a long time of use. Aging pump pipe will not only affect the flow accuracy, but also may lead to leakage and other safety problems.
Poor flow consistency: When multiple pump heads or multiple pump tubes are used at the same time, the flow consistency between different pump heads or pump tubes may be poor due to differences in pump tube material, wall thickness, inner diameter, etc., and small differences in pump head design. This will affect the accuracy and stability of the overall flow control.
Noise problems: Although some micro-peristaltic pumps use silencing technology to reduce noise, in some application scenarios, their operating noise may still have a certain impact on the environment. Especially in places with high noise requirements, such as laboratories, hospitals, etc., special attention is needed.
Cost considerations: Although the micro-peristaltic pump has many advantages, its manufacturing cost is relatively high. This is mainly due to its precision manufacturing process and high quality pump pipe materials. Therefore, when choosing a micro-peristaltic pump, it is necessary to consider factors such as its performance, cost and service life.
In summary, the micro-peristaltic pump has a wide range of application prospects in the field of fluid transportation, but it is also necessary to pay attention to its shortcomings and limitations during use. Through reasonable selection, use and maintenance, it can give full play to its advantages and reduce the impact of disadvantages.
