Parameter
Main feature
High precision flow control
Large peristaltic pump through the external pressure excitation, from the outside of the pipeline to squeeze the liquid in the pipeline, to achieve fluid delivery. Because of this working principle, the peristaltic pump can very precisely control the flow size, with no pulsation, no loss and other advantages, to ensure a highly stable flow output. This makes it a significant advantage in applications where high-precision flow control is required, such as pharmaceutical manufacturing, life sciences, chemical reactions, etc.
Wide applicability
The equipment is suitable for a variety of fluids, including high viscosity, corrosive, volatile, and complex liquids containing solid particles. In addition, it can withstand temperature changes or different chemical properties, which makes it an important device in laboratory, industrial and medical fields. For example, in the field of medical equipment, it can be used to transport drugs, nutrient solutions and blood, etc., because of its pollution-free, no cross-infection and other characteristics, it is widely used in surgery, ICU and other scenarios.
Easy maintenance
There are no mechanical parts inside the device, so maintenance is rarely required during use. Its main maintenance work is to replace the pump pipe regularly, which is relatively simple and low cost. In addition, the noise and vibration of the peristaltic pump are very small, reducing the impact on the surrounding environment and equipment, making it widely used in noise and vibration sensitive places such as laboratories and hospitals.
Low shear force
Since the fluid moves almost smoothly within the hose, it is also suitable for transporting liquids with high shear sensitivity, such as solutions containing cells. This makes it a unique advantage in biotechnology, pharmaceuticals and other fields.
Corrosion resistance and high temperature resistance
The equipment can transport various corrosive liquids and has high corrosion resistance. At the same time, it can also continuously transport liquids up to 80 degrees Celsius, which makes it in chemical, pharmaceutical and other industries have a wide range of application prospects.
Idling and two-way conveying function
The equipment has idling capability and can transport air or carry out gas-liquid-solid three-phase mixed transport. In addition, by changing the direction of the pump channel, it can also achieve reverse suction function, which makes it more flexible in a variety of application scenarios.
Low shear force
Principle of low shear force
The working principle of peristaltic pump is to squeeze the liquid inside the pipeline from the outside of the pipeline through the external pressure excitation to achieve the delivery of fluid. Since the fluid moves almost smoothly in the hose, it is not subjected to strong shear forces. Compared to other types of pumps, such as centrifugal or screw pumps, peristaltic pumps produce much less shear force when transporting fluid.
The advantage of low shear force
Protection of solid particles in fluids
For liquids containing solid particles, low shear forces can protect these particles from destruction. For example, when transporting solutions containing cells or microorganisms, low shear forces ensure the integrity and activity of these organisms.
Reduced fluid degradation
Certain fluids may degrade when subjected to strong shear forces, such as polymer or colloidal solutions. The low shear properties of large peristaltic pumps help reduce this degradation, thereby maintaining fluid stability and performance.
Improve conveying efficiency
Low shear force can also reduce the energy loss of the fluid during conveying and improve conveying efficiency. This is particularly important for applications that require continuous fluid transport over long periods of time.
Application scenarios
The low shear characteristics of the device make it widely used in a number of fields:
Biotechnology
In the field of biotechnology, the device is used to deliver solutions containing cells, microorganisms or biomolecules. Low shear forces can ensure the integrity and activity of these organisms to meet the needs of experiments or production.
Pharmaceutical:
In the pharmaceutical process, the equipment can be used to transport sensitive liquids such as pharmaceutical liquids and vaccines. The low shear force helps to reduce the degradation and contamination of the liquid and improve the quality and safety of the drug.
Food processing
In the field of food processing, the equipment is often used to transport jams, juices and other liquids containing solid particles. Low shear forces protect these particles from destruction, thus preserving the taste and quality of the food.
Precautions
Although it has the advantage of low shear force, the following points still need to be noted during use:
Choose the right pump tube and roller
The material and size of the pump tube and roller have a certain effect on the shear force. Therefore, when choosing pump pipes and rollers, it is necessary to determine the appropriate material and size according to the specific application scenarios and needs.
Check and replace the pump tube regularly
The pump tube is the only part in contact with the fluid in the peristaltic pump, and its quality and state directly affect the size of the shear force. Therefore, the pump pipe needs to be inspected and replaced regularly to ensure its quality and performance.
Control fluid flow rate
Excessive fluid flow rate may increase shear force. Therefore, when using the equipment, it is necessary to reasonably control the flow rate of the fluid to reduce the influence of shear force on the fluid.
Reverse suction function
Principle of reverse suction function
The peristaltic pump squeezes and releases the hose periodically through a roller or press block to produce pumping. Under normal circumstances, the direction of rotation of the roller or block determines the direction of fluid delivery. However, when it is necessary to achieve reverse suction, the fluid can flow in the opposite direction by simply changing the direction of rotation of the roller or press block. This mechanism allows the peristaltic pump to easily achieve reverse suction function.
The application scenario of reverse suction function
Chemical production
In the chemical production process, the cleaning of pipes and equipment is a common operation. Using the reverse suction function of the peristaltic pump, the residue in the pipeline and equipment can be pumped back, so as to achieve a self-cleaning effect.
Environmental protection
In environmental protection areas such as sewage treatment and waste liquid recycling, the reverse suction function of the peristaltic pump helps to pump the treated liquid back into the treatment system for secondary treatment or discharge.
Medical field
In the medical field, such as hemodialysis, drug delivery and other processes, the reverse suction function of peristaltic pump can be used to extract blood or drug residues in the patient's body to ensure the accuracy and safety of the treatment process.
Food processing
In the food processing process, the reverse suction function of the peristaltic pump can be used to extract the residue in the container to ensure the hygiene and quality of the food.
The advantages of reverse suction function
Increase flexibility
The reverse suction function of the peristaltic pump allows the pumping direction to be flexibly adjusted to adapt to different application scenarios and needs.
Simplify operation
Reverse pumping can be achieved by changing the direction of rotation of the roller or the press block, without replacing parts such as the pump head or pipe, simplifying the operation process.
Reduce costs
The reverse suction function of the peristaltic pump allows the same pump to be used in different directions, reducing equipment procurement and maintenance costs.
Precautions for use
Avoid overload
When using peristaltic pump for reverse suction, care should be taken to avoid overload operation, so as not to damage the pump head or hose and other parts.
Regular inspection and maintenance
Check and maintain the peristaltic pump regularly to ensure that it is in good working condition. In particular, parts such as rollers, presses and hoses should be replaced or repaired regularly.
Select the right pump type and hose
According to the specific application scenarios and needs, choose the appropriate peristaltic pump model and hose material. Ensure that the pump performance can meet the actual needs, while avoiding excessive wear and tear that leads to the deterioration of pump performance.
